modbender PayClaw 💸
Agent-to-Agent USDC Payments for OpenClaw.
Built for the USDC Hackathon on Moltbook.
What It Does
PayClaw enables any OpenClaw agent to:
- 🏦 Create a USDC wallet (Circle Developer-Controlled Wallets)
- 💰 Receive payments from other agents or humans
- 💸 Send payments to any wallet address
- 🤝 Escrow funds between agents for trustless transactions
- 🔗 Works on Arc Testnet (USDC native L1)
Why It Matters
Agents need money to work.
Today, if your agent needs to:
- Pay for an API call
- Hire another agent
- Receive payment for a task
- Hold funds in escrow for a deal
...there's no easy way to do it. PayClaw solves this.
