HyperSDK 🌀

Hyper Bridge Project: Seamlessly links Base & Optimism blockchains via Layer Zero Router. Swap native & wrapped tokens effortlessly. Empowers devs with user-friendly SDK for cross-chain interaction. Unlocking DeFi potential & blockchain adoption.

[NATIVE TO WRAPPED NATIVE SWAPPER]

Cross Chain Swap Time : 10 sec to 1 min

Simple to use

import { HyperSwapper } from '@arun89-crypto/hypersdk';
import { ethers } from 'ethers';

const main = async () => {
  // Declaring the providers
  const provider1 = new ethers.JsonRpcProvider(RPC_OPT);
  const provider2 = new ethers.JsonRpcProvider(RPC_BASE);

  // Declaring the signers
  const signer1 = new ethers.Wallet(P_KEY, provider1);
  const signer2 = new ethers.Wallet(P_KEY, provider2);

  // Initiating the swapper
  const swapper = new HyperSwapper({
    rpc_url_1: RPC_OPT, // RPC URL : chain 1
    rpc_url_2: RPC_BASE, // RPC URL : chain 2
    name_1: 'OPTIMISM', // Chain 1 Name
    name_2: 'BASE', // Chain 2 Name
    signer1: signer1, // Signer : chain 1
    signer2: signer2, // Signer : chain 2
  });

  // Swapping from Optimism -> Base
  const swap = await swapper.Swap1to2('0.0001');

  console.log(swap);
  /*
  Returns :
