Intro

The library contains set of function to be used to access Astar dApp staking v3 pallet. More info on dApp staking can be found in the docs

How to use

import { ApiPromise, WsProvider } from "@polkadot/api";
import { Keyring } from "@polkadot/keyring";
import {
  initApi,
  getClaimLockAndStakeBatch,
} from "@astar-network/dapp-staking-v3";

/**
 * Staking demo
 */
async function stakeTest(): Promise<void> {
  // Initialize Polkadot api
  const wsProvider = new WsProvider("wss://rpc.shibuya.astar.network");
  const api = await ApiPromise.create({ provider: wsProvider });

  // Initialize keyring and create a signer account.
  const keyring = new Keyring({ type: "sr25519", ss58Format: 5 });
  const alice = keyring.addFromUri("//Alice");

  // Initialize dApp staking api
  initApi(api);

  // Stake on a dApp
  // Call dApp staking api to get a batch call to lock and stake
  const stakeAmount = 5_000_000_000_000_000_000n;
  const stakeBatch = await getClaimLockAndStakeBatch(
    alice.address,
    stakeAmount,
    [
      {
        address: "0xb196bac674bc0e02e78db10e3c015ed4ec802658",
        amount: stakeAmount,
      },
    ]
  );

  // Sign and send the batch call.
  await stakeBatch.signAndSend(alice, (result) => {
    console.log("Stake result:", result.status.toHuman());
  });
}

stakeTest()
  .catch((err) => console.error(err.message))
  .finally(() => process.exit());

TODOs

• Test cases

  • Find good test case for staker rewards (Just wait for an era to pass and update block number in .env)
  • Bonus reward - find a suitable account
    • getUnstakeCall needs also account with bonus rewards

• Use i18n or create consts for all strings
