  walletUrl: 'https://wallet.nearprotocol.com',
};

async function initNear() {
  // Connect to NEAR RPC
  const near = await nearlib.connect(config);
  const walletAccount = new nearlib.WalletAccount(near);

  // Login via NEAR web wallet
  const account = await walletAccount.requestSignIn('denver-evm', 'EVM Deployment');
  const accountId = walletAccount.getAccountId();

  // Instantiate the near web3 provider
  return new NearProvider(config.nodeUrl, config.deps.keyStore, accountId, config.networkId, 'denver-evm');
