Quick start

Example, how to create and fill a limit order:

import Web3 from 'web3';import {    LimitOrderBuilder,    LimitOrderProtocolFacade,    Web3ProviderConnector,} from '@1inch/limit-order-protocol';
const contractAddress = '0x5fa31604fc5dcebfcac2481f9fa59d174126e5e6';const walletAddress = '0x4758822de63992df27cacf1ba11417bbacace033';const chainId = 1;
const web3 = new Web3('...');// You can create and use a custom provider connector (for example: ethers)const connector = new Web3ProviderConnector(web3);
const limitOrderBuilder = new LimitOrderBuilder(    contractAddress,    chainId,    connector);
const limitOrderProtocolFacade = new LimitOrderProtocolFacade(    contractAddress,    connector);
// Create a limit order and it's signatureconst limitOrder = limitOrderBuilder.buildLimitOrder({    makerAssetAddress: '0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c',    takerAssetAddress: '0x111111111117dc0aa78b770fa6a738034120c302',    makerAddress: walletAddress,    makerAmount: '100',    takerAmount: '200',    predicate: '0x',    permit: '0x',    interaction: '0x',});const limitOrderTypedData = limitOrderBuilder.buildLimitOrderTypedData(    limitOrder);const limitOrderSignature = limitOrderBuilder.buildOrderSignature(    walletAddress,    limitOrderTypedData);
// Create a call data for fill the limit orderconst callData = limitOrderProtocolFacade.fillLimitOrder(    limitOrder,    limitOrderSignature,    '100',    '0',    '50');
// Send transaction for the order filling// Must be implementedsendTransaction({    from: walletAddress,    gas: 210_000, // Set your gas limit    gasPrice: 40000, // Set your gas price    to: contractAddress,    data: callData,});

Note: you can use any implementation for the provider.
Just implement the ProviderConnector interface:

class MyProviderConnector implements ProviderConnector {    //...}
