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.

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.

v0.8.0

v0.8.0 of the Hedera JSON RPC Relay exposes improvements around relay cost reduction, tool support and E2E test coverage support for HIP 514 scenarios.

Rate Limit support by IP was added. In this case a simple in memory map is used to honor the thresholds defined for the requests per a given window of time. This is an initial attempt to allow relay operators to more fairly distribute relay access.

The eth_getBalance endpoint was updated to query the mirror node api/v1/account endpoint to retrieve real time balance updates. This reduces the number of calls to network nodes.

The relay acceptances tests now have E2E support for all HIP 514 precompile functions. Additionally, the tests were updated to utilize 0.30.0 of services and 0.64.0. mirror node images.

We expanded our exploration efforts with an example of a subgraph to showcase an initial example of how The Graph could be connected to Hedera.
As part of this effort some improvements to the relay were added such as ensuring a 15m gas limit was enforced to transaction submissions.

v0.7.0

v0.7.0 of the JSON RPC Relay brings improvements in the areas of troubleshooting, transaction precheck and scenario test coverage.

Troubleshooting of calls sees an improvement with the addition of the request-id to the call response. Developers can now take the request-id in an error response and use it to trace the logs through out the relay stack trace.

The Hedera Javascript SDK dependency was bumped to v2.18.0, with it bringing a fix regarding contract local queries. Relay accounts should now see more appropriate charges for local calls. Other minor dependency packages were also updated.

With upcoming token management precompile features the relay has added the 1st set of coverage support tests to help showcase HIP 514 function usage in local-node scenarios.

An improvement to the account balance precheck was added to handle scenarios where the account does not exist on the Hedera network. In this case the response highlights the issue to developers.

IERC20 approval allowance test coverage was added to showcase E2E usage of the redirect precompile flow.

Postman API tests saw a bug correction in which the eth_getBalance test was using the incorrect endpoint.
