Send Transaction

Make sure you initialize Blocto SDK first

Once your app is connected to Blocto wallet, it can send transactions on behalf of the user, with the user's permission.

In order to send a transaction, the SDK provides two methods of signing for SendTransaction:

1. T app needs to:

• Create data which is the content of transacting with a smart contract

• Create value if needs to send the Ether to smart contract

Parameter	Type	Description
fromAddress	address string	the sender address
toAddress	address string	the smart contract address
value	BigInteger	the amount of Ether deposit in the smart contract (if the smart contract accepts ether)
data	hex string (0x prefix)	the content of transacting with a smart contract, can use library, such as NEthereum, to generate

var web3 = new Web3("{your node url}");
var contract = web3.Eth.GetContract("{your smart contract abi json}", "{your smart contract address}");
var function = contract.GetFunction("{Function name of the call}");
var data = function.GetData(new object[]{ "{function parameters}" });
bloctoWalletProvider.SendTransaction(
    fromAddress: address, 
    toAddress: "{your smart contract address}"
    value: 0, 
    data: data, 
    callback: txId => {
        Debug.Log("TxId: {txId}");
    });

1. Using the EvmTransaction class. The SDK defines a Class that includes four properties: From, To, Value, and Data. Users can create an instance of this Class, set the property values accordingly, and then pass it to SendTransaction.

var web3 = new Web3("{your node url}");
var contract = web3.Eth.GetContract("{your smart contract abi json}", "{your smart contract address}");
var function = contract.GetFunction("{Function name of the call}");
var data = function.GetData(new object[]{ "{function parameters}" });
var transaction = new EvmTransaction{
    From = address,
    To = "{your smart contract address}",
    Value = 0,
    Data = data
};

bloctoWalletProvider.SendTransaction(
    evmTransaction: transaction,
    callback: txId => {
        Debug.Log("TxId: {txId}");
    });
