Generate Fee Payment Signature

await avnSdk.proxyUtils.generateFeePaymentSignature(feeData, signerAddress);

• signerAddress: The AvN address of the signer.

important

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.

Example

const { AvnApi, SetupMode, SigningMode } = require("avn-api");
const AVN_GATEWAY_URL = "https://gateway.testnet.aventus.network";

const singleUserOptions = {
	suri: "0x5392ca60a61aea99fce14358798de93c1bc11c3696a905718738c71fae539c24", // this is from the generated example account
	setupMode: SetupMode.SingleUser,
	signingMode: SigningMode.SuriBased,
};
const avnSdk = new AvnApi(AVN_GATEWAY_URL, singleUserOptions);

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

	let result = await avnSdk.proxyUtils.generateFeePaymentSignature(
		feeData,
		signerAddress
	);
	console.log(result);
}

(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'
