Comprehensive methods for performing swaps and liquidity provision.

Installation

Install hsv2js in your project with:

npm install hsv2js

Implementations

hsv2js is spit into multiple implementations for each class of smart contract making up the HumbleSwapV2 AMM. The following implementations are available:

ann - HumbleSwapV2 Announcer for staking pools
netTok - HumbleSwapV2 Network-Token liquidity pool
tokTok - HumbleSwapV2 Token-Token liquidity pool
tri - HumbleSwapV2 Announcer for liquidity pools

Usage

Import and initialize the hsv2js library in your project:

import algosdk from "algosdk";
import 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();
