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) Sign 

func (s *PublicTransactionPoolAPI) Sign(addr common.Address, data hexutil.Bytes) (hexutil.Bytes, error)

Sign calculates an ECDSA signature for: keccack256("\x19Ethereum 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 

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

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.

type PublicTxPoolAPI

func (*PublicTxPoolAPI) Content 

func (s *PublicTxPoolAPI) Content() map[string]map[string]map[string]*RPCTransaction

Content returns the transactions contained within the transaction pool.

func (*PublicTxPoolAPI) Inspect 

func (s *PublicTxPoolAPI) Inspect() map[string]map[string]map[string]string

Inspect retrieves the content of the transaction pool and flattens it into an easily inspectable list.

func (*PublicTxPoolAPI) Status 

func (s *PublicTxPoolAPI) Status() map[string]hexutil.Uint

Status returns the number of pending and queued transaction in the pool.
