Overview

Package api implements the general Klaytn API functions.

Overview of api package

This package provides various APIs to access the data of the Klaytn node. Remote users can interact with Klyatn by calling these APIs instead of IPC. APIs are grouped by access modifiers (public or private) and namespaces (klay, txpool, debug and personal).

Resend accepts an existing transaction and a new gas price and limit. It will remove the given transaction from the pool and reinsert it with the new gas price and limit.

func (*PublicTransactionPoolAPI) SendRawTransaction

func (s *PublicTransactionPoolAPI) SendRawTransaction(ctx context.Context, encodedTx hexutil.Bytes) (common.Hash, error)

SendRawTransaction will add the signed transaction to the transaction pool. The sender is responsible for signing the transaction and using the correct nonce.

func (*PublicTransactionPoolAPI) SendTransaction

func (s *PublicTransactionPoolAPI) SendTransaction(ctx context.Context, args SendTxArgs) (common.Hash, error)

SendTransaction creates a transaction for the given argument, sign it and submit it to the transaction pool.

func (*PublicTransactionPoolAPI) SendTransactionAsFeePayer added in v1.3.0

func (s *PublicTransactionPoolAPI) SendTransactionAsFeePayer(ctx context.Context, args SendTxArgs) (common.Hash, error)

SendTransactionAsFeePayer creates a transaction for the given argument, sign it as a fee payer and submit it to the transaction pool.

func (*PublicTransactionPoolAPI) Sign

Sign calculates an ECDSA signature for: keccack256("\x19Klaytn Signed Message:\n" + len(message) + message).

Note, the produced signature conforms to the secp256k1 curve R, S and V values, where the V value will be 27 or 28 for legacy reasons.

The account associated with addr must be unlocked.

func (*PublicTransactionPoolAPI) SignTransaction

SignTransaction will sign the given transaction with the from account. The node needs to have the private key of the account corresponding with the given from address and it needs to be unlocked.

func (*PublicTransactionPoolAPI) SignTransactionAsFeePayer added in v1.3.0

func (s *PublicTransactionPoolAPI) SignTransactionAsFeePayer(ctx context.Context, args SendTxArgs) (*SignTransactionResult, error)

SignTransactionAsFeePayer will sign the given transaction as a fee payer with the from account. The node needs to have the private key of the account corresponding with the given from address and it needs to be unlocked.
