		SetCoin("MNT").
		SetValue(big.NewInt(0).Mul(big.NewInt(10), big.NewInt(0).Exp(big.NewInt(10), big.NewInt(18), nil)))

	tx, _ := transaction.NewBuilder(transaction.TestNetChainID).NewTransaction(data)
	signedTx, _ := tx.SetNonce(1).SetGasPrice(1).SetGasCoin("MNT").Sign("07bc17abdcee8b971bb8723e36fe9d2523306d5ab2d683631693238e0f9df142")
