What is Vincent Wallet for AI Agents?
Vincent provides a robust security layer for blockchain-enabled agents, ensuring that private keys are never exposed directly to the AI. By leveraging Openclaw Skills, developers can grant agents the ability to manage assets, execute decentralized exchange (DEX) swaps, and interact with complex smart contracts within strict, user-defined boundaries. All transactions are signed server-side via smart accounts, providing a non-custodial experience for the agent while maintaining full oversight for the human owner.
This skill is designed to bridge the gap between autonomous decision-making and financial execution. Whether the agent is managing a small treasury on Base or participating in prediction markets on Polygon, the Openclaw Skills integration ensures that every action remains within the safety limits of the owner's configured policies, such as spending caps or address allowlists.
Vincent Wallet for AI Agents Use Cases
- Automating token swaps and DeFi interactions based on real-time market triggers.
- Enabling agents to place and manage bets on Polymarket prediction markets using USDC.e.
- Executing treasury transfers or contract interactions within predefined safety boundaries.
- Signing raw messages or transaction hashes for specialized protocols on Ethereum and Solana curves.
How Vincent Wallet for AI Agents Works
- The agent initializes a new wallet via the API, which generates a server-side secret and a unique claim URL.
- The human owner visits the claim URL to take ownership and configure spending policies, such as daily limits or specific token allowlists.
- The agent performs actions by sending requests to the API using a secure Bearer token associated with the wallet.
- Every transaction request is automatically validated against the owner's policies before being signed server-side.
- Compliant transactions are executed gaslessly via a paymaster, while exceptions trigger a manual approval request sent to the owner.
Vincent Wallet for AI Agents Setup
To get started, create a new smart account wallet using a POST request.
curl -X POST "https://heyvincent.ai/api/secrets" \
-H "Content-Type: application/json" \
-d '{
"type": "EVM_WALLET",
"memo": "Agent Wallet",
"chainId": 84532
}'
For users of Openclaw Skills, the resulting API key should be stored in the local credentials directory at ~/.openclaw/credentials/agentwallet/<API_KEY_ID>.json. Provide the claimUrl from the response to the user so they can finalize the wallet setup and set their preferred security policies.
