What is Vincent - A Wallet for AI Agents?
Vincent is a sophisticated wallet infrastructure designed specifically for the agentic economy. It provides a secure bridge for AI agents to interact with decentralized finance (DeFi) protocols, execute token swaps, and manage assets across various EVM chains. By integrating this capability into Openclaw Skills, developers can ensure that agents operate within strictly defined boundaries.
The core value of Vincent lies in its security architecture. The agent never sees the private key; instead, it interacts with a server-side smart account. This allows the human owner to maintain full control through configurable policies, such as spending limits and address allowlists, which are essential when deploying Openclaw Skills in production environments.
Vincent - A Wallet for AI Agents Use Cases
- Automating token swaps and liquidity management for autonomous DeFi agents.
- Enabling AI agents to participate in Polymarket prediction markets using USDC.e.
- Implementing human-in-the-loop approvals for high-value on-chain transactions.
- Providing agents with a gasless environment for sending ETH or ERC-20 tokens via sponsored transactions.
- Using raw message signing for cross-chain protocols involving Ethereum and Solana.
How Vincent - A Wallet for AI Agents Works
- The developer creates a new wallet (EVM, Raw Signer, or Polymarket) via the API, which generates a server-side private key.
- The system returns an API key for the agent and a claim URL for the human owner to authorize the wallet.
- The owner sets specific spending policies and thresholds via the claim interface.
- The AI agent uses the API key to request transactions, such as swaps or transfers, which are automatically checked against the active policies.
- Valid transactions are executed through a ZeroDev smart account with gas fees sponsored by a paymaster, while policy violations trigger human approval requests via Telegram.
Vincent - A Wallet for AI Agents Setup
To get started with this integration for Openclaw Skills, you must first provision a wallet and store the credentials securely.
# Create a new EVM wallet
curl -X POST "https://heyvincent.ai/api/secrets" \
-H "Content-Type: application/json" \
-d '{
"type": "EVM_WALLET",
"memo": "Agent Trading Wallet",
"chainId": 8453
}'
Store the resulting apiKey in ~/.openclaw/credentials/agentwallet/<API_KEY_ID>.json. Ensure the user visits the provided claimUrl to set their spending limits before the agent begins transacting.
Vincent - A Wallet for AI Agents Data Schema & Taxonomy
The skill manages wallet metadata and authentication tokens required for on-chain interactions. The following structure is typical for its data management:
| Attribute | Description |
|---|---|
apiKey |
The bearer token used by the agent for authentication. |
address |
The public address of the smart account or EOA. |
claimUrl |
The management link provided to the user for policy configuration. |
chainId |
The specific EVM chain ID where the wallet is active. |
type |
The wallet architecture (EVM_WALLET, RAW_SIGNER, or POLYMARKET_WALLET). |
Vincent - A Wallet for AI Agents Advanced Features
- Multi-chain support for any EVM-compatible network including Base, Polygon, and Arbitrum.
- Integrated 0x liquidity for token swaps with automatic ERC-20 approval handling.
- Gasless transaction sponsorship, removing the need for agents to hold native gas tokens.
- One-time use re-link tokens for secure recovery of API access by the wallet owner.
- Granular policy engine including daily spending limits and function-level allowlists for smart contracts.
