Notes#

  • eth_sendRawTransaction only accept 155 transaction, 1559, 2930 is not supported
  • Methods not listed here are also not supported.
  • There is no concept of uncle (aka ommer) blocks. The eth_getUncleByBlockHashAndIndex and eth_getUncleByBlockNumberAndIndex methods always return null. The eth_getUncleCountByBlockHash and eth_getUncleCountByBlockNumber methods return zero for valid block IDs and null for invalid block IDs. Additionally, uncle-related block metadata such as sha3Uncles is sha3 of empty hash array.
  • The nonstandard Geth tracing APIs are not supported at present
  • The nonstandard Parity tracing APIs are in progress

pending tag#

Only eth_getTransactionCount method has supported pending tag. Other method will treat pending tag as latest
