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

Name	Type	Description
data	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.

Return Value

Type	Description
20-byte DATA	Recovered address.

Example

// Request
curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"klay_recoverFromTransaction","params":["0x08f88307850ba43b74008366926694000000000000000000000000000000000000dead843b9aca00945bd2fb3c21564c023a4a735935a2b7a238c4cceaf847f8458207f6a09c57511347c7b88c3539a6584b4d57991f6c4665ffcde89da0e9895eb078bef7a0296f4fd2a765567e034f4754cf31a9902c49d6a1d465a2e3fd10b165476cffa8", "latest"],"id":1}' https://public-en-baobab.klaytn.net

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

Name	Type	Description
address	string	The address of the signer account.
message	DATA	Message bytes
signature	65-byte DATA	Signature bytes
block number	QUANTITY | TAG	Integer or hexadecimal block number, or the string "earliest", "latest" or "pending" as in the default block parameter.

Return Value

Type	Description
20-byte DATA	Recovered address.
