Contract Encoder

This interface is currently supported by all contract encoder classes and provides a generic method to encode write function calls.

type ContractEncoder struct {}

func (*ContractEncoder) Encode​

func (encoder *ContractEncoder) Encode(ctx context.Context, signerAddress string, method string, args ...interface{}) (*types.Transaction, error)

Get the unsigned transaction data for any contract call on a contract.

signerAddress: the address expected to sign this transaction

method: the name of the contract function to encode transaction data for

args: the arguments to pass to the contract function.

returns: the encoded transaction data for the transaction.

Example​

toAddress := "0x..."
amount := 1

// Now you can get the transaction data for the contract call.
tx, err := contract.Encoder.Encode(context.Background(), "transfer", toAddress, amount)
fmt.Println(tx.Data()) // Now you can access all transaction data, like the following fields
fmt.Println(tx.Nonce())
fmt.Println(tx.Value())

type ContractEvent​

type ContractEvent struct {
    EventName   string
    Data        map[string]interface{}
    Transaction types.Log
}
