data | DATA | The data to convert into a SHA3 hash. |
Return Value
Type | Description |
|---|---|
32-byte DATA | The SHA3 result of the given data. |
Example
// Request
curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"klay_sha3","params":["0x11223344"],"id":1}' https://public-en-baobab.klaytn.net
// Result
{
"jsonrpc":"2.0",
"id":1,

}
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

}
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. |
