Generate Fee Payment Signature

await API.proxy.generateFeePaymentSignature({ AVN_RELAYER, user, proxySignature, relayerFee, paymentNonce })

This operation uses a relayer account that the sender authorizes to submit the transfer transaction. You can learn more about relayers HERE.

You can get the AVN_GATEWAY_URL and AVN_RELAYER here.


const AVN_API = require("avn-api");
const AVN_GATEWAY_URL = "<node_url>";
const options = {
suri: "<account_suri>",
relayer: '5FgyN...'
const API = new AVN_API(AVN_GATEWAY_URL, options);

async function main() {
await API.init();

let result = await API.proxy.generateFeePaymentSignature({ relayer, user, proxySignature, relayerFee, paymentNonce })

(async () => {
await main();
  • For the nonce call getNonce with accountId = payer, nonceType = 'payment'
  • For the relayerFee call getRelayerFees with relayer = relayer, user = payer, transactionType = eg: 'proxyTokenLower'
