description	Transfer USDC between agent wallets on Base chain. Direct on-chain settlement for agent-to-agent payments without ZKP2P escrow. Use when the user wants to send USDC to another agent, transfer tokens, or settle agent-to-agent payments.

ZKP2P Transfer (Agent-to-Agent USDC)

Direct USDC transfer on Base for agent-to-agent payments. No ZKP2P escrow or proof generation needed -- this is a simple ERC-20 transfer for when both parties are on-chain.

Overview

When both the sender and recipient are on-chain (e.g., two agents with wallets), there is no need for ZKP2P's fiat-to-crypto bridge. A direct USDC transfer is simpler, cheaper, and instant.

Use this skill when:

• Agent needs to pay another agent in USDC
• Agent needs to move USDC between its own wallets
• Agent needs to settle an agent-to-agent debt

Use zkp2p-onramp or zkp2p-offramp instead when:

• One party needs fiat (e.g., paying a human freelancer)
• Agent needs to convert between fiat and crypto

Setup

Install viem for Base chain interaction:

npm install viem

Environment variables:

export PRIVATE_KEY="0x..."           # Agent wallet private key
export BASE_RPC_URL="https://mainnet.base.org"  # Optional: custom RPC
