# Agent wallet (experimental)

> The advanced agent-wallet tools for on-chain operations. Optional, and outside the core payments product.

<Note>
  **Advanced, and non-core.** The agent-wallet tools are optional and sit outside the core payments product. For most integrations the [payment tools](/mcp/setup), the [Payment SDK](/sdk/pay-overview), or the [CLI](/cli/install) are the better fit. This page covers on-chain and self-custody setups.
</Note>

Earlier versions of the MCP server and CLI also exposed an on-chain **agent wallet**, created from a sub-account and driven with an **API key and secret** alongside the gateway key:

```json theme={null}
"env": {
  "AGENTA_API_KEY": "your-api-key",
  "AGENTA_API_SECRET": "your-api-secret",
  "AGENTAOS_GATEWAY_KEY": "sk_test_your-gateway-key"
}
```

Those keys unlocked tools for on-chain operations, contract calls, and message signing. They are not part of the core payments setup. To get paid, use the payments API and the [payment tools](/mcp/setup).
