Using API v2

Using gRPC

Using Transactions

Sign transaction

Returns a signed tx.

⚠️ After sending the transaction, to make sure that the transaction was successfully committed on the blockchain, you need to find the transaction by hash and make sure that the status code is 0.

Single signature

Example

tx, _ := transaction.NewBuilder(transaction.TestNetChainID).NewTransaction(
    transaction.NewSendData().
        SetCoin(0).
        SetValue(big.NewInt(0).Mul(big.NewInt(1), big.NewInt(0).Exp(big.NewInt(10), big.NewInt(18), nil))).
        MustSetTo("Mx1b685a7c1e78726c48f619c497a07ed75fe00483"),
)

signedTransaction, _ := tx.
    SetGasPrice(1).
    SetGasCoin(0).
    SetNonce(1).
    Sign("07bc17abdcee8b971bb8723e36fe9d2523306d5ab2d683631693238e0f9df142")

encode, _ := signedTransaction.Encode()

Multi signatures

Example

tx, _ := transaction.NewBuilder(transaction.TestNetChainID).NewTransaction(
    transaction.NewSendData().
        SetCoin(0).
        SetValue(big.NewInt(0).Mul(big.NewInt(1), big.NewInt(0).Exp(big.NewInt(10), big.NewInt(18), nil))).
        MustSetTo("Mx1b685a7c1e78726c48f619c497a07ed75fe00483")
)

signedTx, _ := tx.SetNonce(1).SetGasPrice(1).SetGasCoin(0).SetSignatureType(transaction.SignatureTypeMulti).Sign(
    multisigAddress,
    "ae089b32e4e0976ca6888cb1023148bd1a9f1cc28c5d442e52e586754ff48d63",
    "b0a65cd84d57189b70d80fe0b3d5fa3ea6e02fa48041314a587a1f8fdba703d7",
    "4c8dbfb3258f383adf656c2131e5ed77ec482a36125db71fb49d29e0528ff2ba",
)

encode, _ := signedTx.Encode()

You can transfer the transaction to the remaining addresses

signedTx1, _ := tx.Sign(msigAddress, privateKey1)
encode, _ := signedTx.Encode()
// transfer encode transaction
signedTx1, _ = transaction.Decode(encode)
// and continue its signature by the remaining participants
signedTx12, _ := signedTx1.Sign(msigAddress, privateKey2)
signedTx123, _ := signedTx12.Sign(msigAddress, privateKey3)
encode, _ := signedTx123.Encode()

You can collect all signatures in one place without revealing the private key

signedTx1, _ := tx.Clone().Sign(msigAddress, "ae089b32e4e0976ca6888cb1023148bd1a9f1cc28c5d442e52e586754ff48d63")
signedTx2, _ := tx.Clone().Sign(msigAddress, "b0a65cd84d57189b70d80fe0b3d5fa3ea6e02fa48041314a587a1f8fdba703d7")
signedTx3, _ := tx.Clone().Sign(msigAddress, "4c8dbfb3258f383adf656c2131e5ed77ec482a36125db71fb49d29e0528ff2ba")
simpleSignatureData1, _ := signedTx1.SingleSignatureData()
simpleSignatureData2, _ := signedTx2.SingleSignatureData()
simpleSignatureData3, _ := signedTx3.SingleSignatureData()
signedTransaction, _ := tx.Clone().Sign(msigAddress)
signedTx123, _ := signedTransaction.AddSignature(simpleSignatureData1, simpleSignatureData2, simpleSignatureData3)

encode, _ := signedTx123.Encode()
