v0.12.0

v0.12.0 of the Hedera JSON RPC Relay brings improvements to gasPrice prechecks, mirror node query management, cache management and test coverage.

Occasionally it was witnessed that gasPrice calculations may be off by 1 tinybar when exchange rates change. During an eth_submitRawTransaction this provided an undesired user experience. To improve this, the relay supports a GAS_PRICE_TINY_BAR_BUFFER to allow closely prices transactions in range to make it through.

In failed EthereumTransaction scenarios the Mirror Node currently does not return a transaction index in the contracts results query. Previously this broke the expectations of a valid response value with the relay <-> mirror node interactions. As a work around the relay handles this scenario and allows for transaction receipts to still be returned.

The Mirror Node processes a record file / block every 2 seconds. This may sometimes mean requests to get info on transactions submitted less than 2 seconds ago may result in a not found. To manage this we added (on a 2nd attempt) retry logic to manage the need to wait for one more block time.

The js-cache was replaced with lru-cache package to support LRU capabilities and additionally caching logic. In this way the relay can customize the maximum number of items in cache and also the maximum time any objects may stay in cache.

A DEV_MODE mode option was added to the relay to allow support for customized local node behaviours. In this may features may be configured to prioritize local development in non production environments.

Acceptance tests were adde to increase coverage or the eth_getStorageAt endpoint which allows state querying on a contract.

v0.12.0-rc1

Full Changelog: v0.11.0...v0.12.0-rc1

v0.11.0

Enhancements

V0.11.0 of the Hedera JSON RPC Relay adds improvements to error handling and logging, gives additional configuration control, provides additional examples of functionality and lastly enhances compatibility with other EVM chains.

To improve log visibility, a request id has been added to acceptance tests and the evm_addresses had been added to contract logs. Error handling has been improved in order to give better feedback to developers. Lastly, the log object will return the EVM address rather than the Hedera address for compatibility.

Rate limiting can now be disabled via an environment variable for local testing.

An example was added for doing HTS token associations in the DApp example.

The admin key will no longer be set on contract create in order to provide parity with other EVM implementations.

• Bump 0.11.0 #676
• Bump 0.11.0-rc1 #671
• Set Request ID on Acceptance Tests #659
• Add env variable to control rate limiting #655

v0.11.0-rc1

Full Changelog: v0.10.0...v0.11.0-rc1

v0.10.0

v0.10.0 of the Hedera JSON RPC Relay adds support to a new endpoint eth_maxPriorityFeePerGas as well as improvements to IHederaTokenService precompile contract access, rate limiting, subgraph support and metamask NFT support.

The eth_maxPriorityFeePerGas API endpoint was added to increase our coverage of the RPC API methods expected by tools.

The relay was updated to support direct calls to the IHederaTokenService precompile contract. eth_getCode calls to the IHederaTokenService contract won't fail and in this way developers can make calls to the contract from their dev tools using the contract address without requiring a wrapper contract on ledger to route the call.

Rate limiting logic continues to be improved, in this release a bug was fixed in which some clients were unnecessarily being throttled.

Subgraph support was also expanded and documentation updated to highlight the current extent of support - The Graph Integration. Advancements will continue to be made as they become possible with the Mirror EVM Archive Node.

A metamask issue was also resolved in which NFTs being loaded into Metamask were witnessing a UI stall due to limited Metamask logic. The relay was updating to support additional logic to better report serial details and support Metamask RPC calls.

v0.10.0-rc1

Full Changelog: v0.9.0...v0.10.0-rc1

v0.9.0

v0.9.0 of the Hedera JSON RPC Relay brings improvements to the eth_getBalance and eth_getTransactionCount as well as increased support for metrics and rate limiting.

eth_getBalance was updated with support to filter search based on blockNumberOrTag, thus allowing for historic balance queries against the Mirror Node.

eth_getTransactionCount was updated to query the Mirror Node instead on consensus nodes, further more reducing the expenses by the relay.

The relay rate limit logic was expanded to include HBAR rate limiting. Now access to relay calls can be more evenly spread by rate limiting accounts based on HBAR consumption.

The SDKClient transaction and transactionRecord execution logic was updated to use TransactionRecordQuery to help improve metrics and better capture costs for the relay account.

The Helm charts were updated to support rate limit configuration on deployment in kubernetes environments. With this relay runners can customize rate limit tier values and windows to their use case.

Multiple API response schema improvements were made to improve expected formats of outputs utilized by development client tools.
