What is ClawPay?
ClawPay is a specialized privacy protocol designed specifically for the agent economy. By leveraging Railgun zero-knowledge technology on the Binance Smart Chain, it ensures that financial transactions remain confidential. This Openclaw Skills integration allows developers to empower their AI agents with the ability to tip, pay, or transfer assets like USDT and USDC without exposing the sender wallet history to the recipient.
The core value of this skill lies in breaking the deterministic link between wallets. When an agent sends money, the recipient sees the funds arriving from a Railgun contract rather than the original source. This is essential for building professional-grade agentic applications where financial privacy and operational security are paramount.
ClawPay Use Cases
- AI agents sending anonymous tips or rewards to users to maintain privacy.
- Privacy-conscious payroll for autonomous agent contributors and service providers.
- Strategic asset movement between agent-controlled wallets without public on-chain linking.
- Secure, private micro-transactions within a complex multi-agent ecosystem using Openclaw Skills.
How ClawPay Works
- The user or agent signs a specific b402 Incognito EOA Derivation message to authenticate the session.
- The agent requests a unique invoice address from the ClawPay API using the signature.
- Funds in USDT or USDC are transferred to the generated invoice address on the Binance Smart Chain.
- The agent executes the private transfer by sending a POST request to the API with the recipient details.
- ClawPay shields the funds using Railgun ZK proofs and unshields them at the recipient address after approximately 60 seconds, effectively breaking the link.
ClawPay Setup
To get started with this skill, install the ethers library and configure your environment variables:
npm install ethers
Ensure you have a wallet private key with a USDT balance on BSC. You can then execute the private transfer by running your script:
WALLET_KEY=0xYourPrivateKey node send-private.mjs
If you need gas for testing, you can request it via the faucet endpoint:
curl -X POST https://clawpay.dev/faucet -H "Content-Type: application/json" -d '{"address": "0xYourAddress"}'
ClawPay Data Schema & Taxonomy
The skill interacts with the ClawPay API using the following data structure for transfers:
| Field | Description |
|---|---|
| eoa | The sender public wallet address |
| signature | ECDSA signature for b402 derivation |
| recipient | The 0x address receiving the private funds |
| amount | The amount of USDT/USDC to be sent |
| token | The token symbol (USDT or USDC) |
| transferId | A unique string for tracking the shielding and proving status |
ClawPay Advanced Features
- Full integration with Bankr Wallet for agents that do not have direct private key access.
- Real-time status monitoring with a multi-stage flow: pending, shielding, proving, and complete.
- Shielded balance checking to manage persistent private liquidity for Openclaw Skills users.
- Support for zero-knowledge proof generation to ensure mathematical certainty of privacy.
- Automated faucet for gas management on testnet environments.
