How to Deploy a Contract

You can deploy your contract using JS, which could come in handy (ex. if doing it on a browser)

Prerequisites

• You should have your compiled contract ready (go to How to Compile Contract for instructions on how to compile contracts)
• Aztec Sandbox running (go to Getting Started for instructions on how to install and run the sandbox)

Deploy

Contracts can be deployed using the aztec.js library. aztec-nargo can generate a handy typescript binding you can use to deploy the contract and call its functions:

aztec-nargo compile # generate contract artifacts
aztec-postprocess-contract # transpile contract and generate verification keys
aztec codegen ./your/contract -o src/artifacts

This would take the compiled contract and create a typescript file like YourContract.ts. You can now import it into your file, for example:

import { YourContract } from './src/artifacts/YourContract.ts';

Then you can use its own class to deploy:

const contract = await YourContract.deploy(wallet, "constructorArg1")
    .send({ from: wallet.getAddress() })
    .deployed();

console.log(`Contract deployed at ${contract.address.toString()}`);

Deploy Arguments

There are several optional arguments that can be passed:

The deploy(...) method is generated automatically with the typescript class representing your contract.

Additionally the .send() method can have a few optional arguments too, which are specified in an optional object:

deploy_options

export type DeployOptions = {
  /** An optional salt value used to deterministically calculate the contract address. */
  contractAddressSalt?: Fr;
  /** Set to true to *not* include the sender in the address computation. */
  universalDeploy?: boolean;
  /** Skip contract class publication. */
  skipClassPublication?: boolean;
  /** Skip publication, instead just privately initialize the contract. */
  skipInstancePublication?: boolean;
  /** Skip contract initialization. */
  skipInitialization?: boolean;
} & SendMethodOptions;
