To support eip2930 and eip1559 transactions we have to sign transactions with access list data https://docs.metamask.io/services/reference/ethereum/json-rpc-methods/eth_createaccesslist/ Access list created from that method We should return empty array always ``` { "accessList": [] "gasUsed": "0x125f8" } ``` We have to discuss about gasUsed property. maybe we can use estimateGas or constant value???
