Hi @kcolbchain - checking in on this PR!

All tests pass and the implementation follows the same patterns as the existing codebase. The AgentEscrow/NonceManager/GasBudget contracts are ready for production use.

Is there anything you'd like me to adjust or clarify? Happy to make changes if needed. This would unblock several agent-to-agent payment use cases.

Thanks for the contribution. Closing this for the same reason as #9 — gas budget tracking should be a client-side utility, not a smart contract. Putting it on-chain creates a circular dependency: every gas tracking operation costs gas (and would itself need to be tracked).

The right design: a Python class that wraps a wallet/signer and rejects transactions when the wallet's hourly/daily gas budget is exceeded.

If you want to convert this to Python, happy to review again. Or pick up another issue across the org.
