Aztec.js

Aztec.js is a library that provides APIs for managing accounts and interacting with contracts on the Aztec network. It communicates with the Private eXecution Environment (PXE) through a PXE implementation, allowing developers to easily register new accounts, deploy contracts, view functions, and send transactions.

Usage

Create a new account

import { getSchnorrAccount } from '@aztec/aztec.js';
import { GrumpkinPrivateKey } from '@aztec/types';

const encryptionPrivateKey = GrumpkinPrivateKey.random();
const signingPrivateKey = GrumpkinPrivateKey.random();
const wallet = getSchnorrAccount(pxe, encryptionPrivateKey, signingPrivateKey).waitDeploy();
console.log(`New account deployed at ${wallet.getAddress()}`);

Deploy a contract

import { Contract } from '@aztec/aztec.js';

const contract = await Contract.deploy(wallet, MyContractArtifact, [...constructorArgs]).send().deployed();
console.log(`Contract deployed at ${contract.address}`);

Send a transaction

import { Contract } from '@aztec/aztec.js';

const contract = await Contract.at(contractAddress, MyContractArtifact, wallet);
const tx = await contract.methods.transfer(amount, recipientAddress).send().wait();
console.log(`Transferred ${amount} to ${recipientAddress} on block ${tx.blockNumber}`);

Call a view function

import { Contract } from '@aztec/aztec.js';

const contract = await Contract.at(contractAddress, MyContractArtifact, wallet);
const balance = await contract.methods.getBalance(wallet.getAddress()).view();
console.log(`Account balance is ${balance}`);
