1 Is infura free ethereum endpoint fully supports EIP-1898 ?
2. What kind of ethereum Archival node(Archival Trace node or simple Archival Node or even Full node) services an ethereum endpoint ?
Hey, @naim.s, I noticed this was already answered on Infura Discord and I will share it here as well:
-
if you are referring to the methods specified here EIP-1898: Add `blockHash` to JSON-RPC methods which accept a default block parameter. accepting a block hash as a parameter, I think it works, although our documentation eth_getBalance - Infura Docs specifies that a hexa block number should be used. I tested eth_getBalance both with the block number and its hash as a parameter and the result was the same.
