Manage Gas

Outline:

• GET /api/gas/estimate?chain_id=… — current gas price and a recommendation.

• POST /api/gas/swap — convert USDC to ETH on Base, sponsored by ShredPay.

• Pre-flight check pattern: estimate → swap if low → send.

• What to do on chains without gas_swap (manual native-token funding).

• Monitoring native balances across chains.
