Hi! Does the rsk mainnet public node support call by blockHash ( [EIP-1898: Add `blockHash` to JSON-RPC methods which accept a default block parameter.](https://eips.ethereum.org/EIPS/eip-1898) ) yet?

Also, does the json-rpc methods provided at [JSON-RPC - RSK Developers Portal](https://developers.rsk.co/rsk/node/architecture/json-rpc/) support call by blockHash?

Hi @GuplerSaxanoid ! Currently RSK public nodes do not support EIP-1898. We expect this to be supported in RSKj Iris v3.1.0, to be released soon after Iris v3.0.0, which has not been released yet, is activated. I believe Iris v3.1.0 will be released by late August. There is already a PR implementing this feature here: [Implementation of EIP-1898 in RSKj JSON-RPC Methods by Vovchyk · Pull Request #1581 · rsksmart/rskj · GitHub](https://github.com/rsksmart/rskj/pull/1581).
