ulujs

ulujs is a JavaScript library for interacting with smart contracts on the AVM blockchains. It provides a convenient interface for interacting with the smart contract tokens, nfts, and dexes.

Features

• Interaction with smart contract tokens (arc200, arc72)
• Comprehensive methods for performing swaps and liquidity provision (swap200)

Installation

Install ulujs in your project with:

npm install ulujs

Implementations

• arc200 - ARC200 Smart Contract Token
• arc72 - ARC72 Smart Contract NFT
• hsv2 - HumbleSwap Protocol (v2)
• swap200 - ARC200 Bases Liqudity Pool (AMM)
• nt200 - ARC200 Wrapped Network Token (wVOI)

Usage

Import and initialize the ulujs library in your project:

import algosdk from "algosdk";
import { arc200 as Contract } from "hsv2js";

// Initialize Algod client
const algodClient = new algosdk.Algodv2(algodToken, algodServer, algodPort);
const indexerClient = new algosdk.Indexer(
  indexerToken,
  indexerServer,
  indexerPort
);

// Initialize ARC200 Contract instance
const tokenId = 123456; // Replace with your token ID
const contract = new Contract.netTok(tokenId, algodClient, indexerClient);

Event queries

The query argument may be used to retrieve matching events:

const { minRound, maxRound, address, round, txid } = query || {};

minRound and maxRound may be used to specify a range of rounds to query events from. address may be used to filter events by address. round and txid may be used to retrieve events from a specific round or transaction ID.

The following events are available for extended ARC200 token functionalities:

getEvents

Retrieve all events of the ARC200 token.

await contract.getEvents();
//{
//   arc200_Transfer: {
//     name: "arc200_Transfer",
//     signature: "...",
//     selector: "...",
//     events: [

//         10000000000000000n,
//       ],
//       ...
//     ]
//   },
//   arc200_Approval: {
//     name: "arc200_Approval",

//         10000000000000000n,
//       ],
//       ...
//     ]
//   }
//}
