### License/Terms of Use: <br>


## Use Case: <br>
Developers and engineers use this skill to build dApps with MetaMask smart accounts, gas abstraction, delegation flows, and ERC-7715 advanced permissions. It helps agents answer implementation questions and draft code, configuration, and command examples for smart-account workflows. <br>

### Deployment Geography for Use: <br>
Global <br>

## Known Risks and Mitigations: <br>
Risk: Generated wallet or smart-account code can move assets or authorize future transactions if chain IDs, recipients, token amounts, expiry times, caveats, or delegation scopes are wrong. <br>
Mitigation: Use testnets first and verify all transaction, permission, and delegation parameters before running code with real accounts or funds. <br>
Risk: Private keys, signer credentials, or wallet secrets may be exposed if inserted into source code, prompts, logs, or client-side applications. <br>
Mitigation: Keep private keys and credentials out of prompts, logs, repositories, and browser code; use secure key management and environment-specific secret handling. <br>
