const ever = new ProviderRpcClient();

async function myApp() {
  if (!(await ever.hasProvider())) {
    throw new Error('Extension is not installed');
  }

  const { accountInteraction } = await ever.requestPermissions({
    permissions: ['basic', 'accountInteraction'],
  });
  if (accountInteraction == null) {
    throw new Error('Insufficient permissions');
  }

  const selectedAddress = accountInteraction.address;
  const dePoolAddress = new Address('0:bbcbf7eb4b6f1203ba2d4ff5375de30a5408a8130bf79f870efbcfd49ec164e9');

  const dePool = new ever.Contract(DePoolAbi, dePoolAddress);

  const transaction = await dePool
    .methods
    .addOrdinaryStake({
      stake: '10000000000',
    }).send({
      from: selectedAddress,
      amount: '10500000000',

      .getParticipantInfo({
        addr: selectedAddress,
      })
      .call();
    console.log(output);
  } catch (e) {
