General Transfer
Overview
DApp requires users to initiate a TRX transfer.
Prerequisite
The DApp developer completes the request to connect to the website, and the user approves to the connection.
The DApp sends a request asking the user to connect the wallet to the website, and the user approves to the connection.
It takes 3 steps to initiate a transfer on the TRON network:
- 1.Create a transfer transaction
- 2.Sign the transaction
- 3.Broadcast the signed transaction
In this process, Step 2 requires TronLink while both Step 1 and 3 happen on tronWeb.
Specification
Example
if (window.tronLink.ready) {
const tronweb = tronLink.tronWeb;
const fromAddress = tronweb.defaultAddress.base58;
const toAddress = "TAHQdDiZajMMP26STUnfsiRMNyXdxAJakZ";
const tx = await tronweb.transactionBuilder.sendTrx(toAddress, 10, fromAddress); // Step1
try {
const signedTx = await tronweb.trx.sign(tx); // Step2
await tronweb.trx.sendRawTransaction(signedTx); // Step3
} catch (e) {
// error handling
}
}
When “await tronweb.trx.sign(tx);” is executed, a pop-up window will show in the TronLink wallet asking the user to confirm, as shown below:
If the user chooses on “Reject” in the pop-up window, an exception will be thrown, which the developer can catch for further processing.
If the user chooses “Sign” in the pop-up window, the DApp receives and broadcasts the signed transaction.
