DATA

RLP encoded transaction bytes

block number

QUANTITY | TAG

Integer or hexadecimal block number, or the string "earliest", "latest" or "pending" as in the default block parameter.

klay_recoverFromMessage

Returns signer address from message signature. It validates if the message is signed by the given account. Klaytn has several accountKey types. So if the address(account) argument has a composite accountKey like AccountKeyWeightedMultisig and the signature is generated by a member private key of the account, you will get the paired address with the member's private key, not account address. And you can be sure that the key used for signing the message is a member of the account. Additionally this function has an ability to validate a signature in the two kind of prefix when signing a message, "\x19Ethereum Signed Message:\n" and "\x19Klaytn Signed Message:\n"

Parameters

NameTypeDescription

address

string

The address of the signer account.

message

DATA

Message bytes

signature

65-byte DATA

block number

QUANTITY | TAG

Integer or hexadecimal block number, or the string "earliest", "latest" or "pending" as in the default block parameter.

Return Value

TypeDescription
