Vincent - A wallet for agents

# Vincent - A wallet for agents

Use this skill to safely create a wallet the agent can use for transfers, swaps, and any EVM chain transaction without ever exposing private keys to the agent. Create a wallet, set spending policies, and your agent can transfer tokens, do swaps, and interact with smart contracts within the boundaries you define.

**The agent never sees the private key.** All transactions are executed server-side through a smart account. The wallet owner controls what the agent can do via configurable policies.

## Which Wallet Type to Use

| Type                | Use Case                                  | Network                 | Gas              |
| ------------------- | ----------------------------------------- | ----------------------- | ---------------- |
| `EVM_WALLET`        | Transfers, swaps, DeFi, contract calls    | Any EVM chain           | Sponsored (free) |
| `RAW_SIGNER`        | Raw message signing for special protocols | Any (Ethereum + Solana) | You pay          |
| `POLYMARKET_WALLET` | Prediction market trading                 | Polygon only            | Sponsored (free) |

**Choose `EVM_WALLET`** (default) for:

- Sending ETH or tokens
- Swapping tokens on DEXs
- Interacting with smart contracts
- Any standard EVM transaction

**Choose `RAW_SIGNER`** only when you need:

- Raw ECDSA/Ed25519 signatures for protocols that don't work with smart accounts
- To sign transaction hashes you'll broadcast yourself
- Solana signatures

**Choose `POLYMARKET_WALLET`** only for:

- Betting on Polymarket prediction markets
- Requires USDC.e on Polygon for funding

## Configuration

All API requests require a Bearer token (the API key returned when creating a wallet). If you're an openclaw instance, store and retrieve it from `~/.openclaw/credentials/agentwallet/<API_KEY_ID>.json`. Otherwise, you can store it in your current working directory at `agentwallet/<API_KEY_ID>.json`.

```
Authorization: Bearer <API_KEY>
