Tron Provider

FoxWallet uses the same protocol as TronLink, only supports Mainnet and Shasta currently.

Get Provider

function getProvider() {
const provider = window.foxwallet && window.foxwallet.tronLink;
if (!provider) {
window.open("https://foxwallet.com/download");
throw `Please guide users to download from FoxWallet official website`;
}
if (!provider.ready) {
throw `The provider is not ready, please try reopen current page again.`;
}
return provider;
}

} catch (e) {
console.log('connect failed');
}

console.log("signed message ", signedMessage);
} catch (e) {
console.log('sign message failed');
}
}

sign

Sign a transaction

  • Returns: Promise
  • Example:
function transfer(transaction, privateKey) {
try {
const provider = getProvider();
const tradeobj = await provider.tronWeb.transactionBuilder.sendTrx("TNo9e8MWQpGVqdyySxLSTw3gjgFQWE3vfg", 100,"TM2TmqauSEiRf16CyFgzHV2BVxBejY9iyR",1);
const signedtxn = await provider.tronWeb.trx.sign(tradeobj, privateKey);
const receipt = await provider.tronWeb.trx.sendRawTransaction(signedtxn);
console.log(receipt);
} catch (e) {
console.log('transfer failed');
}
}

multiSign

Sign a transaction with permissionId

  • Returns: Promise
  • Example:
function transfer(transaction, privateKey) {
try {
const provider = getProvider();
const tradeobj = await provider.tronWeb.transactionBuilder.freezeBalance(provider.tronWeb.toSun(100), 3, "ENERGY", "415d73f56d93a9380a100d2a340dd30dc3df6e0746", "415d73f56d93a9380a100d2a340dd30dc3df6e0746", 0);
const signedtxn = await provider.tronWeb.trx.multiSign(tradeobj, privateKey, 0);
const receipt = await provider.tronWeb.trx.sendRawTransaction(signedtxn);
console.log(receipt);
} catch (e) {
console.log('transfer failed');
}
}

Tips

The tronWeb is a dynamic instance that will be reinitialized when necessary, so the recommend way to access it from FoxWallet:

  const provider = getProvider();
const balance = await provider.tronWeb.getBalance(address);
const signedMsg = await provider.tronWeb.signMessage(message, privateKey);
...

not recommend:

  const tronWeb = getProvider().tronWeb;
const balance = await tronWeb.getBalance(address);
const signedMsg = await tronWeb.signMessage(message, privateKey);
