The v3-sdk is a TypeScript library for interacting with StoryHunt V3, offering utilities for swaps, position management, and more.

Installation

npm install @storyhunt/v3-sdk

Key Features

• Generate optimized swap routes.

• Compute liquidity position fees.

• Encode calldata for on-chain execution.

Example Usage

1. Import and Configure:

   import { Pool, Trade, SwapRouter } from '@storyhunt/v3-sdk';

2. Create Pool:

   const pool = new Pool(
               tokenA,
               tokenB,
               parseInt(pool.feeTier),
               JSBI.BigInt(pool.sqrtPrice),
               JSBI.BigInt(pool.liquidity),
               parseInt(pool.tick),
               tickDataProvider
             );
             
   const trade = await Trade.bestTradeExactIn(
           allPools,
           CurrencyAmount.fromRawAmount(
             currencyIn,
             JSBI.BigInt(amount.toString())
           ),
           currencyOut,
           { maxHops: 3, maxNumResults: 1 }
         );

3. Encode calldata:

   const { calldata, value } = SwapRouter.swapCallParameters(trade, {
         slippageTolerance: new Percent(JSBI.BigInt(50), JSBI.BigInt(10000)), // 0.5%
         deadline: JSBI.BigInt(Math.floor(Date.now() / 1000) + 60 * 20), // 20 minutes from now
         recipient: address,
       });
