hashgraph/hedera-json-rpc-relay v0.31.1

on GitHub

Release 0.31.1 of the Hedera JSON RPC Relay includes initial support for eth_filter, improved SubGraph examples, withdrawals and withdrawalsRoot properties with default values to eth_getBlockByHash requests, a fix to eth_getBalance to accept a hash, and added unsupported eth_newPendingTransactionFilter. Also implemented more efficient requests to the mirror-node contract/results endpoint, to remove the need for any follow up additional requests and overall reduced latency.

Library changes include a migration to ethers.js V6, and an upgrade of OpenZeppelin, Web3.js, and protobufs.

It also includes design documents for the distributed cache and filter API.
