Setup snapshot

git clone https://github.com/RHinAK/usdc-agent.git

1
Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

name: usdc-agent description: "Enable AI agents to autonomously manage USDC - create wallets, check balances, send payments, bridge cross-chain via CCTP, and handle x402 pay-per-use API flows. Use when an agent needs to pay for services, transfer funds, manage treasury across chains, or interact with paywalled APIs."

USDC Agent Skill

Enable AI agents to autonomously transact with USDC using Circle's Programmable Wallets and Cross-Chain Transfer Protocol (CCTP).

Prerequisites

Circle API key from Circle Developer Console
Store the API key:

security add-generic-password -a "clawdbot" -s "circle-api-key" -w "YOUR_API_KEY"

Install dependencies:

cd /path/to/usdc-agent && npm install

Quick Start

Create a Wallet

./scripts/usdc-cli.ts wallet create
# Returns: wallet address and ID

Check Balance

./scripts/usdc-cli.ts balance 0x1234...abcd
# or check all wallets
./scripts/usdc-cli.ts balance --all

Send USDC

./scripts/usdc-cli.ts send --to 0xRecipient --amount 10.00 --chain base-sepolia

Bridge Cross-Chain (CCTP)

./scripts/usdc-cli.ts bridge --from ethereum --to solana --amount 100.00

Pay for x402 API

./scripts/usdc-cli.ts pay402 "https://api.example.com/data"
# Automatically handles 402 Payment Required flow

Supported Chains

| Chain | Network ID | USDC Contract | |-------|-----------|---------------| | Ethereum | ethereum | 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 | | Base | base | 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 | | Polygon | polygon | 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 | | Arbitrum | arbitrum-one | 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 | | Solana | solana | EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v |

Testnet: Use base-sepolia, ethereum-sepolia, polygon-amoy for testing.

x402 Payment Flow

The x402 protocol enables pay-per-use APIs. When a server responds with 402 Payment Required:

CLI parses payment requirements from response
Signs payment authorization using Circle Wallets
Retries request with signed payment in X-PAYMENT header
Returns API response after payment settles

// Programmatic usage
import { pay402 } from './scripts/usdc-client';

const response = await pay402({
  url: 'https://api.example.com/premium-data',
  maxAmount: '1.00', // Max willing to pay
  walletId: 'your-wallet-id'
});

Cross-Chain Transfers (CCTP)

CCTP enables native USDC transfers without wrapped tokens:

USDC burned on source chain
Circle attestation confirms burn
USDC minted on destination chain

Typical transfer time: 10-20 minutes (standard) or ~10 seconds (fast transfer).

# Standard transfer (cheaper, ~15 min)
./scripts/usdc-cli.ts bridge --from base --to solana --amount 50.00

# Fast transfer (~10 sec, higher fee)
./scripts/usdc-cli.ts bridge --from base --to solana --amount 50.00 --fast

API Reference

Environment Variables

CIRCLE_API_KEY - Circle API key (or use keychain)
USDC_DEFAULT_CHAIN - Default chain for operations (default: base-sepolia)
USDC_WALLET_SET_ID - Wallet set ID for grouping wallets

Wallet Operations

createWallet(): Promise<{ address: string, walletId: string }>
getBalance(address: string, chain?: string): Promise<string>
listWallets(): Promise<Wallet[]>

Payment Operations

send(to: string, amount: string, chain?: string): Promise<TxHash>
bridge(from: string, to: string, amount: string, fast?: boolean): Promise<TxHash>
pay402(url: string, maxAmount?: string): Promise<Response>

Error Handling

| Error | Cause | Resolution | |-------|-------|------------| | INSUFFICIENT_BALANCE | Not enough USDC | Fund wallet or reduce amount | | INVALID_CHAIN | Unsupported chain | Check supported chains list | | ATTESTATION_TIMEOUT | CCTP attestation delayed | Retry or check Circle status | | PAYMENT_REJECTED | x402 payment failed | Verify amount meets requirements |

Security Notes

Never expose API keys in code
Use testnet for development
Set spending limits per wallet
Review x402 payment requests before auto-approving
