Example
klay_recoverFromTransaction
Returns the recovered sender address from RLP encoded transaction bytes. If the sender address of the tx has composite accountKey type, it will return the sender address, not the addresses extracted from signatures. If the recovery failed, it returns 0x0 address.
Parameters
data
DATA
RLP encoded transaction bytes
block number
QUANTITY | TAG
Return Value
20-byte DATA
Recovered address.
Example
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
address
string
The address of the signer account.
message
DATA
Message bytes
signature
65-byte DATA
Signature bytes
block number
QUANTITY | TAG
Return Value
20-byte DATA
Recovered address.
