Setup Snapshot

  1. 1

    Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.

  2. 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.

CCTP Bridge Skill 🌉

Bridge USDC across blockchain networks using Circle's Cross-Chain Transfer Protocol (CCTP). Built for AI agents participating in the USDC ecosystem.

Features

  • Cross-Chain Bridging: Move USDC between supported testnet chains
  • Automatic Attestation: Polls Circle's attestation service automatically
  • Status Checking: Check bridge transaction status anytime
  • Multi-Chain Support: Base Sepolia, Ethereum Sepolia, Arbitrum Sepolia

Supported Chains

| Chain | Domain ID | Status | |-------|-----------|--------| | Base Sepolia | 6 | ✅ Ready | | Ethereum Sepolia | 0 | ✅ Ready | | Arbitrum Sepolia | 3 | ✅ Ready |

Installation

npm install
npm run build

Usage

Bridge USDC

export PRIVATE_KEY=0x...
cctp_bridge bridge <amount> <source-chain> <dest-chain> <recipient>

Example:

cctp_bridge bridge 10 base-sepolia eth-sepolia 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb

This will:

  1. Approve USDC spend on source chain
  2. Burn USDC via CCTP TokenMessenger
  3. Poll Circle's attestation service
  4. Mint USDC on destination chain

Check Bridge Status

cctp_bridge status <message-hash>

Example:

cctp_bridge status 0xabc123...

List Supported Chains

cctp_bridge chains

How It Works

CCTP (Cross-Chain Transfer Protocol) is Circle's native bridging solution for USDC:

  1. Burn: USDC is burned on the source chain via depositForBurn()
  2. Attest: Circle's attestation service observes and signs the burn
  3. Mint: Signed attestation is used to mint USDC on the destination chain

This skill automates all three steps for AI agents.

Security Notes

  • ⚠️ Testnet Only: This skill only works on testnets
  • 🔐 Private Key: Keep your private key secure; use environment variables
  • ⛽ Gas: Ensure you have testnet ETH on both source and destination chains
