FHE x402 Payment Skill

Private, encrypted payments for autonomous agents on Ethereum using Zama's Fully Homomorphic Encryption (fhEVM). All payment amounts are encrypted on-chain — only the payer and payee can see them.

Quick Start

Set a wallet and RPC, then run any command:

# Minimal setup (local dev)
export USER_PRIVATE_KEY=0x...
export RPC_URL=https://sepolia.infura.io/v3/YOUR_KEY

# Check wallet info
run info

# Wrap 10 USDC into encrypted cUSDC
run wrap --amount 10
