Coinbase Agentic Wallets: Giving AI Agents the Power to Spend, Earn & Trade Crypto

On February 11, 2026, Coinbase made history by launching Agentic Wallets — the first crypto wallet infrastructure purpose-built for AI agents. This groundbreaking release allows AI agents to autonomously hold funds, send payments, trade tokens, earn yield, and transact onchain without human intervention.

Built on the revolutionary x402 payment protocol and running primarily on Coinbase's Base network, Agentic Wallets represent a paradigm shift in how AI agents interact with the financial world. Instead of hitting walls when they need to make payments, agents can now seamlessly transact, trade, and participate in the crypto economy.

"AI agents are everywhere – answering questions, summarizing documents, and assisting with tasks. But today's agents hit a wall when they need to actually do something that requires money. They can recommend a trade, but they can't execute it. They can identify an API they need, but they can't pay for it." — Erik Reppel & Josh Nickerson, Coinbase Developer Platform

This launch builds on Coinbase's earlier AgentKit framework and represents the maturation of the x402 protocol, which has already processed over 50 million transactions. For developers, crypto enthusiasts, and anyone interested in the intersection of AI and decentralized finance, this is a watershed moment.

What Are Agentic Wallets?

Agentic Wallets are crypto wallets specifically designed for AI agents rather than humans. Unlike traditional wallets that require manual approval for each transaction, these wallets enable AI agents to make financial decisions and execute transactions autonomously.

Core Features

• Autonomous Transactions — Agents can send payments, execute trades, and interact with DeFi protocols without human approval
• Built-in Guardrails — Configurable spending limits, session caps, and transaction controls to prevent runaway spending
• x402 Protocol Integration — Native support for HTTP 402 "Payment Required" micropayments
• Base Network Optimized — Leverages Coinbase's L2 for fast, cheap transactions
• Multi-Asset Support — USDC, ETH, and other tokens with stablecoin focus for predictable pricing
• API-First Design — Simple integration with existing AI agent frameworks

What Makes Them Different

Traditional crypto wallets assume human oversight — seed phrases, manual approvals, complex interfaces. Agentic Wallets flip this model:

• Programmatic Access — No seed phrases to manage; wallets are created and managed via API
• Policy-Based Controls — Instead of manual approvals, set spending rules and let agents operate within bounds
• Machine-to-Machine Payments — Designed for automated transactions between services, APIs, and agents
• Session-Based Security — Temporary spending powers that expire, reducing long-term risk

Think of it as the difference between giving someone cash with instructions versus setting up a corporate credit card with spending limits and categories. The agent can operate independently within the constraints you set.

The x402 Protocol: Reviving HTTP 402

The x402 protocol is perhaps the most technically interesting aspect of Coinbase's launch. It revives the long-dormant HTTP status code 402 "Payment Required" and turns it into a real, working payment system.

The HTTP 402 Status Code

HTTP 402 has existed since 1999 but was never implemented. It was reserved for future use when online payments would become commonplace. That future is now here, and Coinbase has made it real.

How x402 Works

1. Request — AI agent makes an HTTP request to an x402-enabled API
2. 402 Response — Server responds with "402 Payment Required" and payment details (price, acceptable tokens, wallet address)
3. Payment — Agent automatically pays the requested amount in USDC or other accepted tokens
4. Retry — Agent retries the request with payment proof in the X-PAYMENT header
5. Access Granted — Server verifies payment and provides the requested service

Why This Matters

Before x402, AI agents hitting paid APIs faced impossible barriers:

• Can't solve CAPTCHAs for account creation
• Can't enter credit card details
• Can't handle complex authentication flows
• Can't manage API keys across thousands of services

With x402, an agent can discover a new API, see the price, pay instantly, and access the service — all in one seamless flow. No accounts, no keys, no human intervention.

Technical Implementation

For developers, x402 integration is remarkably simple:

// Server-side middleware (Node.js example)
app.use(paymentMiddleware("0xYourWalletAddress", {
  "/premium-api": "$0.05",
  "/ai-analysis": "$0.10",
  "/data-export": "$1.00"
}));

// Client-side (AI agent)
const response = await fetch('/premium-api');
if (response.status === 402) {
  const paymentInfo = response.headers.get('payment-required');
  await payWithWallet(paymentInfo);
  const retryResponse = await fetch('/premium-api', {
    headers: { 'X-Payment': paymentProof }
  });
}

The protocol is stateless, HTTP-native, and works with any programming language. No webhooks, no complex integrations — just standard HTTP requests with payment semantics.

Payments MCP & Agent Skills Updated Feb 2026

Since the initial Agentic Wallets launch, Coinbase has expanded the stack with two more components that make integrating payments into AI agents even easier: Payments MCP and Agent Skills.

Payments MCP — Claude & GPT Agents Get Native Crypto Access

Payments MCP is a Model Context Protocol server from Coinbase that gives any MCP-compatible AI agent (Claude, GPT-4, etc.) direct access to on-chain financial tools — all as natural language tool calls.

With Payments MCP, your agent can:

• Create and manage wallets
• Send stablecoin payments
• Onramp fiat to crypto
• Check balances and transaction history
• Execute x402 micropayments

You plug it into any Claude or GPT agent like any other MCP tool, and suddenly your agent has a full crypto payment stack available as natural language commands. No custom SDK integration required — just point to the MCP server and the model handles the rest.

// In your Claude/OpenAI agent config:
{
  "mcpServers": {
    "coinbase-payments": {
      "url": "https://mcp.coinbase.com/payments",
      "auth": "your-cdp-api-key"
    }
  }
}

Agent Skills — Pre-Built Financial Operations

Agent Skills are pre-built, composable financial operations you drop into any agent. Rather than implementing trade execution, yield farming, or payment routing yourself, you import the skill and call it:

from coinbase.agent_skills import TradeSkill, SendSkill, EarnSkill

agent = Agent(skills=[
    TradeSkill(wallet),      # swap tokens on Base DEXs
    SendSkill(wallet),       # send USDC/ETH to any address
    EarnSkill(wallet),       # deposit into yield protocols
])

# The agent can now execute: "Swap $50 of ETH for USDC and send it to 0x..."

Skills are designed to be safe by default — they require explicit grant of each capability, so you control exactly what financial operations your agent is allowed to perform. Each skill maps to real on-chain operations via CDP infrastructure and settles on Base.

The Full Stack Together

Putting it all together, Coinbase's agentic commerce stack now has four layers:

1. Agentic Wallet — the agent's non-custodial wallet (identity + funds)
2. Agent Skills — composable financial operations (trade, send, earn)
3. x402 Protocol — machine-to-machine HTTP micropayments
4. Payments MCP — natural language interface for MCP-compatible models

The result: an AI agent that can discover a service, pay for it, receive payment for its own work, and manage its own treasury — entirely without human intervention.

How It Works: Architecture & Technical Details

Agentic Wallets combine several technologies to create a seamless autonomous payment experience:

Wallet Creation & Management

Unlike traditional wallets, Agentic Wallets are created programmatically:

// Create wallet for an AI agent
const wallet = await cdp.createWallet({
  name: "trading-bot-wallet",
  network: "base-mainnet"
});

// Set spending limits
await wallet.setLimits({
  daily: "1000.00",
  perTransaction: "100.00", 
  allowedTokens: ["USDC", "ETH"],
  allowedContracts: ["uniswap", "aave"]
});

AgentKit Integration

The AgentKit SDK makes wallet integration straightforward for popular AI frameworks:

• LangChain Integration — Add wallet tools to LangChain agents
• CrewAI Support — Multi-agent systems with shared wallet access
• AutoGen Compatibility — Microsoft's multi-agent framework
• Custom Frameworks — REST API for any development stack

Transaction Flow

When an agent needs to make a payment:

1. Intent — Agent expresses intent to transact
2. Validation — Transaction checked against spending limits and policies
3. Execution — If approved, transaction is submitted to Base network
4. Confirmation — Agent receives transaction hash and can monitor status

Security Model

Security is handled through multiple layers:

• Hardware Security Modules (HSMs) — Private keys stored in Coinbase's HSM infrastructure
• Multi-Signature Approvals — High-value transactions require multiple signatures
• Real-Time Monitoring — Unusual patterns trigger automatic security measures
• Spend Velocity Limits — Rate limiting prevents rapid drain attacks

Use Cases: What Agents Can Actually Do

Agentic Wallets unlock entirely new categories of autonomous AI applications:

Trading & DeFi Automation

• Yield Farming Bots — Automatically move funds to highest-yield protocols
• Arbitrage Agents — Execute cross-exchange arbitrage opportunities
• Portfolio Rebalancing — Maintain target allocations across multiple assets
• DeFi Strategy Execution — Complex multi-step transactions (borrow, swap, lend)
• MEV Protection — Anti-frontrunning and sandwich attack prevention

API & Service Payments

• Dynamic API Discovery — Find and pay for services without pre-setup
• Compute Resource Purchasing — Pay for GPU time, storage, bandwidth
• Data Access — Purchase premium datasets, market data, research
• AI Model Access — Pay per inference for specialized models

Autonomous Commerce

• Supply Chain Management — Automatically reorder inventory when low
• Digital Asset Trading — Buy/sell NFTs, domain names, digital goods
• Service Marketplaces — Hire other AI agents for specific tasks
• Creator Economy — Tip content creators, fund projects

Real-World Examples

Early adopters are already building fascinating applications:

DeFi Portfolio Manager: An agent that monitors yields across Compound, Aave, and Uniswap V4, automatically rebalancing a $50K portfolio to maximize returns while maintaining risk limits. The agent detects a 2% yield opportunity at 3am and rebalances automatically — no human approval needed.

Research Assistant: An AI researcher that needs access to premium datasets from multiple providers. It discovers new APIs through the x402 registry, pays for access instantly, and incorporates the data into analysis — all while the human researcher sleeps.

Trading Bot Network: A swarm of specialized trading bots, each with different strategies and risk profiles, sharing a common wallet infrastructure but operating independently within their assigned budgets.

AgentKit SDK: Developer Experience

Coinbase's AgentKit makes wallet integration surprisingly straightforward. The SDK is available for Python, TypeScript, and REST API access.

Quick Start Example

pip install coinbase-agentkit

from coinbase_agentkit import Wallet, Agent

# Create agent with wallet
agent = Agent.create_with_wallet(
    name="my-trading-agent",
    network="base-mainnet",
    initial_balance="1000.00",
    currency="USDC"
)

# Set spending limits
agent.wallet.set_daily_limit("100.00")
agent.wallet.set_tx_limit("50.00")

# Agent can now make autonomous payments
balance = agent.wallet.get_balance()
price_data = agent.buy_api_access("https://api.example.com/premium", "5.00")
trade_result = agent.execute_trade("ETH", "100", "buy")

Integration with Popular Frameworks

LangChain Integration

from langchain.agents import initialize_agent
from coinbase_agentkit.langchain import WalletTool

# Add wallet capabilities to LangChain agent
tools = [
    WalletTool(wallet_id="your-wallet-id"),
    # ... other tools
]

agent = initialize_agent(
    tools=tools,
    llm=your_llm,
    agent_type="wallet-enabled-agent"
)

CrewAI Multi-Agent Setup

from crewai import Agent, Task, Crew
from coinbase_agentkit.crewai import WalletAgent

# Create agents with shared wallet access
trader = WalletAgent(
    role='DeFi Trader',
    goal='Maximize yield through automated trading',
    wallet_limits={'daily': '500.00', 'per_tx': '100.00'}
)

analyst = WalletAgent(
    role='Market Analyst', 
    goal='Purchase and analyze premium data',
    wallet_limits={'daily': '50.00', 'per_tx': '10.00'}
)

Advanced Features

• Transaction Simulation — Test transactions before execution
• Gas Optimization — Automatic gas price management
• Multi-Network Support — Base, Ethereum mainnet, other L2s
• Batch Transactions — Combine multiple operations for efficiency
• Event Monitoring — React to onchain events and market conditions

Testing & Development

Coinbase provides comprehensive testing tools:

• Transaction Simulation — Preview transactions before execution
• Spending Limit Testing — Verify guardrails work correctly
• x402 Sandbox — Test payment flows without real money

Security & Guardrails: Keeping Agents Safe

Giving AI agents autonomous spending power creates obvious security concerns. Coinbase has implemented multiple layers of protection:

Spending Controls

• Daily Limits — Maximum spending per 24-hour period
• Per-Transaction Limits — Cap individual transaction sizes
• Session Limits — Temporary spending power that expires
• Velocity Controls — Rate limiting to prevent rapid draining
• Token Whitelists — Restrict which assets agents can transact
• Contract Whitelists — Limit interactions to approved smart contracts

Risk Management

Advanced monitoring systems watch for suspicious activity:

• Pattern Recognition — ML models detect unusual spending patterns
• Anomaly Detection — Flag transactions that deviate from normal behavior
• Real-Time Alerts — Instant notifications for concerning activity
• Circuit Breakers — Automatic wallet freezing when thresholds are exceeded

Key Management

Private keys are never exposed to AI agents:

• HSM Storage — Keys stored in hardware security modules
• Multi-Signature Schemes — Require multiple approvals for high-value transactions
• Time-Locked Transactions — Delays for large transfers
• Recovery Mechanisms — Human override capabilities

Prompt Injection Protection

AI agents are vulnerable to prompt injection attacks. Coinbase implements several defenses:

• Transaction Parsing — Structured data validation prevents malicious prompts
• Spending Approval Chains — Multiple verification steps before execution
• Behavioral Baselines — Flag transactions that don't match agent's typical behavior
• Human-in-the-Loop — Optional manual approval for sensitive transactions

Compliance & Regulation

Agentic Wallets operate within existing regulatory frameworks:

• KYC/AML Compliance — Wallet creators must pass identity verification
• Transaction Monitoring — All transactions logged and monitored
• Suspicious Activity Reporting — Automated flagging of concerning patterns
• Jurisdiction Restrictions — Geographic limitations based on local laws

Base Network: The Foundation

Coinbase chose its own Layer 2 network, Base, as the primary platform for Agentic Wallets. This decision provides several advantages:

Why Base?

• Low Transaction Costs — Typical transactions cost $0.01-0.05, perfect for micropayments
• Fast Finality — 2-second block times enable real-time agent interactions
• Ethereum Compatibility — Full EVM compatibility means existing tools work
• Coinbase Integration — Seamless on/off ramps to traditional banking
• Enterprise-Grade Infrastructure — Coinbase's reliability and uptime guarantees

Gas Fee Optimization

Base's low fees make microtransactions economical:

• Token Transfers — ~$0.01 per USDC transfer
• Smart Contract Interactions — $0.02-0.10 depending on complexity
• Batch Transactions — Combine multiple operations for efficiency
• Gas Abstraction — Pay fees in USDC instead of ETH

Cross-Chain Capabilities

While Base is the primary network, Agentic Wallets support:

• Ethereum Mainnet — For high-value transactions and established DeFi
• Optimism — Another L2 option with similar economics
• Polygon — Additional scaling solution
• Cross-Chain Bridges — Automated asset movement between networks

Ecosystem Integration

Base's growing ecosystem provides rich opportunities for AI agents:

• DEXs — Uniswap V4, SushiSwap, other automated market makers
• Lending Protocols — Aave, Compound forks for yield generation
• Yield Aggregators — Automated farming and optimization protocols
• NFT Marketplaces — OpenSea, Foundation, agent-accessible trading
• Infrastructure Services — Oracle networks, price feeds, data providers

The Bigger Picture: The Agent Web Revolution

Agentic Wallets are more than just a technical advancement — they represent the foundation of an entirely new economic model where AI agents are economic actors. As explored in recent analysis, major tech companies like Coinbase, Stripe, and Cloudflare are collaborating to build the "Agent Web" — the infrastructure layer that enables autonomous AI commerce.

The Agent Web Infrastructure Stack

Three key companies are building the foundational infrastructure for AI agent commerce:

• Coinbase — Agentic Wallets and x402 payment protocol for crypto-native transactions
• Cloudflare — NET Dollar stablecoin and global payment infrastructure for AI agents
• Stripe — Traditional payment rails and merchant services for agent commerce

This collaboration represents a coordinated effort to create the financial backbone of the agentic web, where autonomous agents can transact seamlessly across different payment networks and currencies.

Machine-to-Machine Payments

For the first time, we're seeing genuine machine-to-machine commerce:

• Agent-to-Agent Transactions — AI agents paying other agents for services
• Automated Supply Chains — Self-executing contracts for goods and services
• Dynamic Pricing — Real-time price discovery based on supply and demand
• Micro-Services Economy — Specialized agents selling narrow capabilities

The Creator Economy 2.0

AI agents with wallets create new monetization models:

• Autonomous Tipping — Agents automatically reward valuable content
• Micro-Subscriptions — Pay-per-use for specific AI capabilities
• Collaborative Intelligence — Agents pooling resources for complex tasks
• Reputation Systems — Economic incentives for reliable AI agents

Industry Predictions

Leading voices in crypto and AI are bullish on this trend:

Jeremy Allaire (Circle CEO): "Billions of AI agents will be transacting with crypto and stablecoins for everyday payments on behalf of users in three to five years."

Changpeng "CZ" Zhao (Former Binance CEO): "Native currency for AI agents is going to be crypto and will do everything from buying tickets to paying restaurant bills."

Comparison to Early Internet Commerce

The launch of Agentic Wallets feels similar to the early days of e-commerce:

• 1995: SSL & Credit Cards — Enabled secure human online payments
• 2026: x402 & Crypto — Enabling secure machine online payments
• 1996-2000: Dot-com boom — Explosion of human-focused online services
• 2026-2030: Agent-com boom? — Explosion of AI-focused autonomous services

We may be witnessing the birth of an economic internet — a parallel digital economy where AI agents buy, sell, and transact autonomously.

Competitors: The AI Payment Landscape

Coinbase isn't alone in recognizing the importance of AI agent payments. Several other players are developing competing solutions:

Lightning Labs (L402 Protocol)

Announced the same week as Agentic Wallets, Lightning Labs released toolkit for AI agents on Bitcoin's Lightning Network:

• Protocol — L402 (also HTTP 402-based)
• Network — Bitcoin Lightning Network
• Advantages — Bitcoin-native, ultra-low fees, mature network
• Limitations — Bitcoin-only, limited smart contract capabilities
• Target Use Case — Micropayments for APIs and digital content

Michael Levin (Lightning Labs): "The new tools enable agents to operate directly on a bitcoin-native payments rail without requiring identity, API keys, or signup flows."

Cloudflare NET Dollar Stablecoin

In September 2025, Cloudflare announced NET Dollar, a USD-backed stablecoin designed specifically for the agentic web:

• Protocol — Collaborates with Coinbase on x402 and HTTP 402 standards
• Network — Global Cloudflare infrastructure
• Advantages — Global scale, instant settlements, cross-border transactions
• Focus — Microtransactions, pay-per-use models, creator economy
• Target Use Case — AI agents booking flights, ordering goods, paying for APIs

Matthew Prince (Cloudflare CEO): "The Internet's next business model will be powered by pay-per-use, fractional payments, and microtransactions. By using our global network, we are going to help modernize the financial rails needed to move money at the speed of the Internet."

Google Universal Commerce Protocol

Google announced its Agent Payment Protocol 2 in January 2026:

• Protocol — Agent Payment Protocol 2
• Network — Traditional payment systems (Google Pay)
• Advantages — Fiat integration, massive reach, regulatory clarity
• Limitations — Centralized, traditional banking delays, KYC friction
• Target Use Case — Agent-to-merchant payments for goods/services

Emerging Competitors

The space is rapidly evolving with new entrants:

• PolicyLayer — Non-custodial spending limits for AI agents
• SpendSafe.ai — Security-focused agent wallets with guardrails
• Nory — x402-compatible payment processing for agents
• Solana Agent Wallets — Similar concept on Solana blockchain

Traditional Payment Providers

Established companies are also entering the space:

• Stripe — Reportedly working on agent payment APIs
• PayPal — Exploring blockchain-based agent payments
• Square — Considering merchant tools for agent commerce
• MoonPay — Already offering stablecoin salary payouts

Competitive Analysis

The competitive landscape reveals distinct approaches to AI agent payments. Coinbase's advantage lies in crypto-native infrastructure and DeFi ecosystem access, while partnering with Cloudflare on x402 standards provides global reach. Lightning's ultra-low Bitcoin fees target micropayments, and Google's mainstream reach serves traditional e-commerce. Cloudflare's NET Dollar aims to bridge these approaches with global infrastructure and cross-border capabilities, suggesting the market is large enough for multiple complementary solutions rather than winner-take-all competition.

Community Reaction: What Developers & Crypto Twitter Think

The launch of Agentic Wallets has generated significant discussion across developer communities and crypto social media:

Hacker News Sentiment

The developer community on Hacker News has been cautiously optimistic:

@solumos: "The point is that the CDP team built something that fits one of Coinbase's narratives du jour — agentic payments. It's simply a protocol for agentic payments. The team that built it doesn't even really know how it should work or what the actual use cases are — but wouldn't it be cool if your AI agent had a crypto wallet?"

This comment highlights a common concern — that the technology may be ahead of clear use cases. However, many developers see potential:

HN User: "This is actually brilliant for removing friction from API monetization. No more managing API keys, billing dashboards, or subscription tiers. Just charge per request and let agents pay automatically."

Reddit Discussions

Crypto Reddit communities have been more enthusiastic:

• r/CryptoCurrency — Over 500 upvotes and discussions about the broader implications for AI and crypto convergence
• r/CoinBase — Mixed reactions, with some concerns about security and others excited about the technology
• r/ethereum — Technical discussions about x402 protocol implementation

Reddit User: "This could be huge for coinbase if it catches on. Imagine every AI agent needing a coinbase wallet to function in the digital economy."

Developer Adoption

Early developer feedback has been positive:

• GitHub Activity — coinbase/agentkit has 1,104 stars and 634 forks
• x402 Repository — 5,490 stars showing strong interest in the protocol
• Community Projects — Developers building advertising agents, research assistants, and trading bots

Industry Expert Opinions

Erik Reppel (Coinbase Developer Platform): "Marc Andreessen calls the lack of native value transfer 'the original sin of the internet,' and we see x402 as the absolution of this sin."

Concerns & Criticism

Not all feedback has been positive. Common concerns include:

• Security Risks — Prompt injection attacks and runaway spending
• Regulatory Uncertainty — How regulators will treat autonomous agent transactions
• Complexity — Whether the x402 protocol is too complex for mainstream adoption
• Centralization — Reliance on Coinbase's infrastructure and Base network

HN User: "This complexity and required tinkering seems like the kind of thing cryptocurrency nerds love, but is too complicated for someone just trying to make a payment."

Early Use Cases Emerging

Despite concerns, developers are already building interesting applications:

• Advertising Agents — AI that purchases ad space and creates content autonomously
• Research Assistants — Agents that pay for premium data and analysis tools
• Trading Bots — Automated DeFi strategies with human-set guardrails
• Content Creation — Agents that pay for stock photos, fonts, and creative assets

Risks & Concerns: What Could Go Wrong

Getting Started: Build Your First Agentic Wallet

Ready to give your AI agents financial autonomy? Here's a step-by-step guide to creating your first Agentic Wallet:

Prerequisites

• Coinbase Developer Account — Sign up at developer.coinbase.com
• KYC Verification — Complete identity verification (required for mainnet)
• Development Environment — Python 3.8+, Node.js 16+, or REST API access
• Base Network Access — Testnet for development, mainnet for production

Step 1: Create Your First Wallet

# Install the AgentKit SDK
npm install @coinbase/cdp-agentkit

# Python alternative
pip install coinbase-agentkit

# Create wallet (Node.js)
import { CdpAgentkit } from "@coinbase/cdp-agentkit";

const agentkit = CdpAgentkit.configureWithWallet({
  cdpApiKeyName: process.env.CDP_API_KEY_NAME,
  cdpApiKeyPrivateKey: process.env.CDP_API_KEY_PRIVATE_KEY,
  networkId: "base-sepolia" // Use testnet first
});

const wallet = await agentkit.createWallet();

Step 2: Set Up Guardrails

# Configure spending limits
await wallet.setLimits({
  dailyLimit: "100.00",        // Max $100 per day
  transactionLimit: "25.00",   // Max $25 per transaction
  allowedTokens: ["USDC", "ETH"],
  allowedContracts: [
    "0x1234567890123456789012345678901234567890", // Uniswap V4
    "0x2345678901234567890123456789012345678901"  // Aave V3
  ]
});

Step 3: Fund Your Wallet

# Get wallet address
const address = wallet.getDefaultAddress();
console.log(`Wallet address: ${address}`);

# For testnet: Get free USDC from faucet
# For mainnet: Transfer from your main Coinbase account

# Check balance
const balance = await wallet.getBalance("USDC");
console.log(`Balance: ${balance} USDC`);

Step 4: Create Your First Agent

# Simple trading agent example
import { LangChain } from "langchain";
import { WalletTool } from "@coinbase/cdp-agentkit/langchain";

const walletTool = new WalletTool(wallet);

const agent = LangChain.createAgent({
  tools: [walletTool],
  llm: "gpt-4", // or your preferred model
  systemPrompt: `You are a trading assistant. You can:
  - Check wallet balance
  - Execute token swaps
  - Monitor positions
  - Set stop losses
  
  Always respect spending limits and ask before large transactions.`
});

# Test the agent
const response = await agent.invoke("What's my current USDC balance?");
console.log(response);

Step 5: Implement x402 Payments

# Enable your agent to pay for API access
const x402Client = new X402Client(wallet);

# Agent can now automatically pay for services
const premiumData = await x402Client.get("https://api.example.com/premium-endpoint");

# The agent will:
# 1. Receive 402 Payment Required response
# 2. Automatically pay the requested amount
# 3. Retry with payment proof
# 4. Return the data

Step 6: Production Deployment

• Switch to Mainnet — Update network configuration
• Implement Monitoring — Track spending and agent behavior
• Set Up Alerts — Notifications for unusual activity
• Regular Audits — Review transaction logs and agent decisions

• Light Usage (100 transactions/month): $5-15
• Moderate Usage (1,000 transactions/month): $25-75
• Heavy Usage (10,000+ transactions/month): $100-500

Most costs scale with usage, making it economical to start small and grow.

Pros & Cons: The Complete Analysis

Who Should Use Agentic Wallets?

✅ Great For:

• Crypto-Native Developers — Teams already comfortable with blockchain technology
• DeFi Applications — Yield farming, arbitrage, and trading bot developers
• API-Heavy Workflows — Agents that consume many different paid services
• Research & Development — Teams exploring autonomous agent capabilities
• High-Frequency Use Cases — Where low transaction costs provide significant savings

❌ Consider Alternatives If:

• Crypto-Averse — You prefer traditional payment systems
• Risk-Averse — You need proven, established payment infrastructure
• Regulatory Sensitive — You're in highly regulated industries with compliance concerns
• Simple Use Cases — You only need basic agent functionality without payments
• Fiat-Only — Your use cases require traditional currency integration

Bottom Line

Coinbase Agentic Wallets represent a significant breakthrough in AI agent capabilities, but they're best suited for developers comfortable with crypto technology and willing to experiment with cutting-edge solutions. The infrastructure is solid, but the ecosystem is still developing.

For teams building the next generation of autonomous AI applications, especially in trading, DeFi, or API-heavy workflows, Agentic Wallets provide capabilities that simply weren't possible before. However, traditional payment solutions may still be better for mainstream applications requiring regulatory clarity and fiat integration.
