Functions

func Dial

func Dial(gethIpcPath string) (*ethclient.Client, error)

Dial connects to network and returns directly the official ETH connected Client.

Is recommended to always construct the *ethclient.Client using this Dial method as it only returns the Client when the blockchain is fully synced to avoid performing TXs from a non-synced state.

func ExtractSender

func ExtractSender(tx *ethTypes.Transaction) (common.Address, error)

func FetchReceipt

func FetchReceipt(client *ethclient.Client, tx *types.Transaction, cfg TxConfig) (*types.Receipt, error)

FetchReceipt periodically checks if transaction was already mined.

Returns TX receipt when transaction succeeds. Error otherwise.

func GenerateTxOpts

func GenerateTxOpts(ctx context.Context, client *ethclient.Client, auth authy.Auth, cfg TxConfig) (*bind.TransactOpts, error)

func SignTransferTx

func SignTransferTx(ctx context.Context, client *ethclient.Client, auth authy.Auth, to common.Address, amount *big.Int, cfg TxConfig) (*types.Transaction, error)
