v0.63.2

Overview

The Hedera JSON-RPC Relay v0.63.2 release enhances reliability for eth_getContractResult and eth_getContractResultsLogs by introducing a polling mechanism to ensure the retrieval of fully mature records from the Mirror Node (MN). This update includes stricter error handling to detect and manage immature records, preventing errors such as “Cannot read properties of null (reading ‘xyz’)” caused by improper null checks. These improvements ensure more stable and consistent RPC responses, reinforcing the robustness of the Relay’s data handling.

Bug Fixes

• fix: added polling logic to ensure the retrieval of fully mature records from MN by @quiet-node in #3368

v0.63.1

Overview

The Hedera JSON-RPC Relay v0.63.1 release improves reliability for eth_getBlockByNumber, eth_getBlockByHash, and eth_getTransactionReceipt by adding robust null checks, enhanced error handling, and fallback mechanisms. It also introduces a retry mechanism to handle incomplete data from the Mirror Node, ensuring stability and consistency in RPC responses.

Bug Fixes

• fix: enhanced reliability of eth RPC methods with null checks and retry mechanisms by @quiet-node in #3349

v0.63.0

Overview

The Hedera JSON-RPC Relay v0.63.0 release introduces two important enhancements to improve the platform's functionality and flexibility. The new OPERATOR tier has been added, expanding the HBAR Limiter’s capabilities to include tailored plans for operators. This feature enables better alignment with operational needs and provides enhanced control for managing transaction limits. Additionally, a precheck for receiver accounts has been incorporated into sendRawTransactionCheck, ensuring that transactions are validated more effectively before execution, enhancing reliability and security.

This release also includes several dependency upgrades, such as updates to golang.org/x/crypto, @emotion/react, and @emotion/styled, ensuring the platform remains compatible with the latest tools and libraries. These updates, along with internal documentation enhancements like the updated hbar-limiter.md for the new OPERATOR tier, demonstrate ongoing efforts to provide a robust and developer-friendly platform.

v0.63.0-rc1

v0.62.0

Overview

The Hedera JSON-RPC Relay v0.62.0 release introduces a significant enhancement with the ability to return HTS token addresses for newly created HTS tokens in transaction receipts. This update ensures that HTS token creation transactions return the correct token address by detecting HTS token creation calls to the system contract, extracting and decoding the token's EVM address from the call result, and including it in the receipt under the contractAddress field, replacing the previous value which was always the HTS system contract address (0x167). This improvement enhances compatibility with Ethereum-based tooling, simplifying workflows for developers and ensuring seamless integration of token creation processes.

Another key update in this release allows transactions with a value of 0 to pass through the system. By removing this restriction, the platform now supports broader use cases, including specific smart contract operations and test scenarios where zero-value transactions are essential. This change also ensures consistency with Ethereum, aligning the platform with industry standards.

This release also includes critical bug fixes, such as improved cache handling for getFilterLogs calls, ensuring consistent and accurate filtering. Dependency upgrades, including updates to web3 and @hashgraph/sdk, enhance compatibility and performance. Internal changes, such as extended format checking via openrpcjson and workflow updates, demonstrate ongoing efforts to maintain a robust and reliable codebase. These updates continue to refine the platform, providing developers with a more powerful and seamless integration experience.

Full Changelog: v0.61.0...v0.62.0

v0.62.0-rc1

v0.62.0-rc1

v0.61.0

Overview

The Hedera JSON RPC Relay v0.61.0 introduces a significant enhancement with the fast transaction hash return mechanism for the eth_sendRawTransaction endpoint. This feature enables the API to return the transaction hash immediately after passing prechecks, with all subsequent processes—such as broadcasting to the network, handling file transactions, polling the mirror node, and tracking HBAR consumption—executed asynchronously in the background. This innovation improves transaction processing speed, providing users with a transaction hash without waiting for the full transaction lifecycle, thereby enhancing both efficiency and user experience. Additionally, this update aligns with Hedera’s ongoing EVM equivalence efforts, ensuring smoother interoperability and compatibility with Ethereum-based tools and workflows.

Important Note on the Fast-Return Mechanism: With the transaction hash returned immediately, clients are responsible for monitoring the transaction status using the hash (e.g., via eth_getTransactionReceipt or confirmation tracking). Internal errors, such as exceeding maxChunkSize, HBAR limits, SDK-related, or any other issues, are no longer reflected in the response. This may result in eth_getTransactionReceipt returning null indefinitely, requiring clients to handle these scenarios appropriately.

In addition, this release includes the option to disable the HBar Rate Limiter, providing greater flexibility for specific use cases. A new design document has also been created to enable access to HTS token EVM addresses, laying the groundwork for further integrations and capabilities within the ecosystem.

Beyond these highlights, the release addresses important bug fixes, including resolving invalid cache records in eth_getBlockByHash. Dependency upgrades, such as updates to @graphprotocol/graph-cli and hedera-local, improve platform compatibility and performance. Internal changes, such as enhanced pre-commit linting and workflow permissions updates, contribute to a more stable and maintainable codebase. These updates reflect the ongoing commitment to improving the Hedera JSON RPC Relay for developers and end-users alike.
