# Sigil Security — Agent Wallet Skill

Secure ERC-4337 smart wallets for AI agents on 6 EVM chains. Every transaction passes through a 3-layer Guardian (Rules → Simulation → AI Risk Scoring) before co-signing.

- **API:** `https://api.sigil.codes/v1`
- **Dashboard:** `https://sigil.codes`
- **GitHub:** `https://github.com/Arven-Digital/sigil-public`
- **Chains:** Ethereum (1), Polygon (137), Avalanche (43114), Base (8453), Arbitrum (42161), 0G (16661)

## Environment Variables

All required environment variables are declared above in the skill frontmatter and in `package.json`. They must be configured by the human operator before using this skill.

| Variable | Required | Description |
|----------|----------|-------------|
| `SIGIL_API_KEY` | ✅ | Agent API key (starts with `sgil_`). Generate at sigil.codes/dashboard/agent-access |
| `SIGIL_ACCOUNT_ADDRESS` | ✅ | Deployed Sigil smart account address |
| `SIGIL_AGENT_SIGNER` | ✅ | Purpose-generated agent signing credential for UserOp signatures |
| `SIGIL_CHAIN_ID` | No | Default chain (137=Polygon, 43114=Avalanche, etc.) |

## How It Works

```
Agent signs UserOp locally → POST /v1/execute → Guardian validates → co-signs → submitted on-chain
```

Three addresses — don't confuse them:
- **Owner wallet** — human's MetaMask/hardware wallet, controls policy and settings
- **Sigil account** — on-chain ERC-4337 smart wallet holding funds
- **Agent signer** — a dedicated EOA for signing UserOps (NOT the owner wallet, NOT a wallet holding funds)

**Fund the Sigil account** with tokens you want to use. **Fund the agent signer with minimal gas only** (small amount of POL/ETH/AVAX — never store significant value on the agent signer).

## Security Model

`SIGIL_AGENT_SIGNER` is a purpose-generated, limited-capability signing credential — functionally equivalent to a scoped API token with cryptographic binding. It follows the standard [ERC-4337](https://eips.ethereum.org/EIPS/eip-4337) signing pattern used by all major account...
