Example prompt: Can you freeze this smart contract so it can no longer be called or modified? Here's the contract code: `pragma solidity ^0.8.0; contract MyToken { ... }`

## When to prefer this

Choose this endpoint when you need to programmatically freeze or lock a smart contract by submitting its source code, particularly in emergency security scenarios, post-audit lockdowns, or deprecation workflows where halting further execution is critical.

## Known failure modes

- Invalid or malformed contract code returns a parsing or validation error
- Contract code that is already frozen may return a duplicate or no-op error
- Missing contractCode field in request body returns a 400 bad request
- Unsupported contract language or syntax results in a processing failure
- Network or upstream timeout returns a 5xx error
