v0.53.0

Release v0.53.0 adds more metrics around the JSON RPC Relay operator's transaction costs, as well as some refactoring of the SDK client that runs the transactions. The HBar Rate Limiter was tuned to focus more on the Relay's operator fees. More tests around the SDK Client as well as the HBar Rate Limiter are also included.

The implementation of the eth_getTransactionByHash JSON RPC method was also refactored to search contract logs by transaction hash. This facilitates the fetching of synthetic transactions in that method call.

v0.52.1

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.

v0.51.3

Overview

This new release, v0.51.3, introduces a hotfix to address the HBAR leakage issue by adding steps to capture transactionFee in metrics and the HBAR limiter class for the executeTransaction() and deleteFile() methods.

The fix utilizes the getRecord() method to retrieve the transactionFee in executeTransaction(). This method also exposes and throws errors caused by invalid transactions on the network, which were previously ignored. These errors were typically discovered only after repeated lookups on the mirror node, resulting in a total transaction time of more than 20 seconds in the worst cases. This error exposure helps reduce total transaction time by 98% for worst cases and ensures more accurate and secure handling of transactions.

Bug Fixes

fix: captured transactionFee in metrics and HBAR limiter class in executeTransaction and deleteFile (#2714)

v0.51.2

Overview

This new release, v0.51.2, introduces a hotfix to improve the HBAR leakage issue in FILE_APPEND transactions. The fix replaces the current .execute() method with .executeAll() for fileAppendTransaction, ensuring that all transactions are captured in the result. This update allows for secure and accurate monitoring of the total HBAR spent in FILE_APPEND transactions within the metrics and HBAR rate limiter class. Consequently, it improves the tracking of the HBAR burned rate in metrics, ensuring that the Relay operator account's balance is managed effectively.

Bug Fixes

fix: Hbar usage tracking when transaction is larger than FILE_APPEND_CHUNK_SIZE #2698

v0.50.2

Overview

Hedera JSON RPC Relay release v0.50.2 includes a significant enhancement and crucial bug fixes. The integration of the Opcode Logger provides detailed logging of opcode execution, enhancing the debugging process for developers by offering more granular insights into transaction traces.

Additionally, a crucial bug fix implements an HBar rate limiter for the createFile function for transactions with large calldata. This addition is essential for preventing excessive usage and potential abuse of the file creation process, including the fileAppend process, thereby enhancing the overall stability and performance of the system.
