v0.14.0

v0.14.0 of the Hedera JSON RPC Relay enhances support for subgraph by adding examples, documentation, tests and CI/CD workflow improvements. A new configuration parameter for using TLS at the network transport layer has been added. The getLogs call has been enhanced to allow for multiple addresses. Lastly, we've reduced the number of calls by returning results from available data vs making an extra call for eth_getTransactionReceipt and removed an unnecessary call in getLogEvmAddress as an issue in mirror node was addressed.

There were also several bug fixes involving the format of the results of the getStorageAt call and the retrieval of past event/ordering in the getLog call.

v0.13.1

v0.13.1 of the Hedera JSON RPC Relay is a minor release which improves the eth_getBalance call to return more accurate historical balances for blocks that is up to 15 minutes before the latest block. In addition, there is a bug fix to improve handling of null or empty to parameter in a transaction.

Enhancements

• eth_getBalance workaround #717

Bug Fixes

• Check to parameter in eth\_call method #744

v0.13.0

v0.13.0 of the Hedera JSON RPC Relay brings improvements to the way several problematic return values from the mirror node are handled. Also, the getLogs call was improved to handle larger result sets.

Fixes for improved handling of null values and empty arrays when retrieving contract results from the mirror node were implemented in this release.

In addition the getLogs call was improved to support pagination for results that are larger than the default result set size of 25 entries.

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

Enhancements

• Handle empty state_changes array in contract details (#733) #734
• Bump test sdk version #729
• Support pagination on getLogs requests #701
• rpc acceptance test for getStorageAt call #553

Bug Fixes

• Fix handling of null amount value when fetching transactions from the mirror node #715
• null value returned for amount by MirrorNode for contract result queries #710
• eth_getLogs returns only 25 results #673

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.
