Deploy Account ​

In this section we will learn how to deploy an Account smart contract and use it in our scripts to send transactions.

Step 1: Write a Deployment Script ​

Let's write a simple script in typescript that will use locklift to deploy our Account.

INFO

Before we start to write our scripts we need to make sure that there is a file named 00-deploy-account.ts in the script folder in the project root.

typescript
/*
  locklift is a globally declared variable
*/

import { Signer, WalletTypes, Address } from "locklift";

async function main() {

  // each mnemonic can generate more that just one key pair, so we specify which pair do we want.
  const keyNumber = "0";
  const balance = 30;

  /* We get a pair of private and public keys,
      which we get from the mnemonic from the config
    SimpleSigner {
      keyPair: {
        secretKey: 'bb2903d025a330681e78f3bcb248d7d89b861f3e8a480eb74438ec0299319f7a',
        publicKey: 'e85f61aaef0ea43afc14e08e6bd46c3b996974c495a881baccc58760f6349300'
      },
      publicKey: 'e85f61aaef0ea43afc14e08e6bd46c3b996974c495a881baccc58760f6349300'
    }
  */

  const signer: Signer = (await locklift.keystore.getSigner(keyNumber))!;

  // Deploying the account contract
  const {contract: account} = await locklift.factory.deployContract({
    contract: "Account",
    publicKey: signer.publicKey,
    constructorParams: {},
    initParams: { _randomNonce: locklift.utils.getRandomNonce() },
    value: locklift.utils.toNano(balance),
  });

  // Adding it to the AccountStorage to be recognized as a sender to be able to send transaction from it
  const loadedAccount = await locklift.factory.accounts.addExistingAccount({
    type: WalletTypes.MsigAccount,
    address: account.address,
    mSigType: "SafeMultisig",
  });

  console.log(`Account deployed at: ${loadedAccount.address.toString()}`);
}

main()
  .then(() => process.exit(0))
  .catch(e => {
    console.log(e);
    process.exit(1);
  });

TIP

  • Giver - is a contract that has a sendTransaction method.
    The local-node already has a pre-installed contract with the initial amount of EVERs. For other networks, you can configure your giver in locklift.config.ts

  • If you need a permanent address for testing, then set the _randomNonce constant. By changing _randomNonce you change the byte code of the contract, and the final address.

  • Kindly Navigate to the Deployment section to see the example of using the Account contract to send transaction from.

Step 2: Deploy the Account ​

Use this command and deploy account:

shell
npx locklift run -s ./scripts/00-deploy-account.ts -n local
deployAccountOutput
