Overview
The latest update to the Hedera JSON RPC Relay, version 0.52.1, introduces a solution to preemptively limit HBAR expenses based on the callDataSize of an eth_sendRawTransaction. This solution estimates the total transaction fee required to complete the eth_sendRawTransaction request based on the callDataSize. It then ensures that the transaction fee does not exceed the remaining budget of the relay operator's account beforehand. If the estimated fee surpasses the available budget, an HBAR_RATE_LIMIT_PREEMPTIVE_EXCEEDED error is triggered. This update represents another step in securing, patching, and improving issues related to HBAR leakage.
