Pull Request Overview
This PR adds default and maximum gas limits to the eth_call RPC method to improve resource safety and align with Ethereum client standards.
- Introduced
DEFAULT_ETH_CALL_GAS_LIMIT(50M) andMAX_ETH_CALL_GAS_LIMIT(100M) constants - Modified
CallRequest::handleto apply default gas limit when none is specified and cap custom gas limits - Enhanced transaction preparation to ensure proper gas limit enforcement before simulation

Using unwrap_or(u64::MAX) could result in unexpected behavior when the gas value exceeds u64 range. The fallback to u64::MAX bypasses the intended capping logic since std::cmp::min(u64::MAX, MAX_ETH_CALL_GAS_LIMIT) would always return MAX_ETH_CALL_GAS_LIMIT. Consider using unwrap_or(MAX_ETH_CALL_GAS_LIMIT) instead to maintain consistent capping behavior.

Why not use DEFAULT_ETH_CALL_GAS_LIMIT as the default value for the unwrap?
You could simplify the match with just the unwrap_or

let gas_limit = transaction
.gas
.and_then(|gas| u64::try_from(gas).ok())
.unwrap_or(DEFAULT_ETH_CALL_GAS_LIMIT);
is simpler

The
eth_callRPC method lacked a server-side gas limit. This change ensures resource safety and aligns with Ethereum client standards.Description
