Stake AVT

Stakes the specified amount of AVT, locking its free usage in order to earn rewards. Staking AVT is the process of becoming a nominator on the network.

note

First time stakers must stake a minimum of 100 AVT.

await api.send.stake(AMOUNT_TO_STAKE);

important

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

important

You can get the AVN_GATEWAY_URL and Relayer here.

JS Example

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

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);

//Amount of AVT in 18 decimals
const AMOUNT_TO_STAKE = "1000000000000000000";

async function main() {
	await avnSdk.init();
	const api = await avnSdk.apis();

	let result = await api.send.stake(AMOUNT_TO_STAKE);
	// Returns a request id
	console.log(result);
}

(async () => {
	await main();
})();

You have now successfully submitted a transaction to the AVN.

Example Result

tip

You can query the state of your transaction here using the returned request id.

JSON-RPC

There are two JSON-RPC methods to staking AVT.

1. proxyStakeAvt - Only to be used for first time stakers.
2. proxyIncreaseStake Only to be used for current stakers.

First Time Stakers - STAKE

"method":"proxyStakeAvt"

This should only be used for first time stakers - please query getStakingStatus to check first.

note

The initial staking requires 2 sets of proofs, one to cover the bonding step and one to cover the nominating step

• user [required] - a string representing the user's SS58 address
• payer [required] - a string representing the payer's SS58 address
• amount [required] - a string integer value representing the full amount of AVT to stake
• targets [required] - The list of validators to nominate
• nonce [required] - string integer value of the current proxy nonce of type 'staking'
