Send Transaction
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.The 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) |
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}");
});
- 2.Using the
EvmTransactionclass. 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}");
});
