Quickstart

Three ways to use DZap. Pick one. The rest are one click away.

SDK (TypeScript)
API (REST)
Widget (React)

Install @dzapio/sdk, get a quote, execute a swap.

npm install @dzapio/sdk viem

import { DZapClient } from '@dzapio/sdk';
import { createWalletClient, http } from 'viem';
import { arbitrum } from 'viem/chains';

const dzap = DZapClient.getInstance();

const quotes = await dzap.getTradeQuotes({
  fromChain: 42161,
  account: '0xYourAddress',
  data: [{
    amount: '1000000',                                            // 1 USDC (6 decimals)
    srcToken: '0xaf88d065e77c8cC2239327C5EDb3A432268e5831',      // USDC
    destToken: '0x82aF49447D8a07e3bd95BD0d56f35241523fBab1',     // WETH
    slippage: 1,
  }],
});

console.log(quotes);

Hit the public endpoints directly, no SDK required.

curl -X POST https://zap.dzap.io/v1/quote \
  -H "Content-Type: application/json" \
  -d '{
    "srcChainId": 42161,
    "destChainId": 42161,
    "account": "0xYourAddress",
    "srcToken": "0xaf88d065e77c8cC2239327C5EDb3A432268e5831",
    "destToken": "0x724dc807b04555b71ed48a6896b6F41593b8C637",
    "amount": "1000000",
    "slippage": 1
  }'

Next: API Introduction · Fuse API · Trade API

Drop a swap form into any React app.

npm install @dzapio/widget viem wagmi

import { ConnectWalletButton, DZapWidgetProvider, SwapWidget } from '@dzapio/widget';
import '@dzapio/widget/styles.css';

const config = {
  walletConnectProjectId: process.env.NEXT_PUBLIC_WC_PROJECT_ID!,
  appName: 'My dApp',
  theme: 'dark' as const,
};

export function App() {
  return (
    <DZapWidgetProvider config={config}>
      <ConnectWalletButton />
      <SwapWidget />
    </DZapWidgetProvider>
  );
}

No API key needed for the public Fuse API. The Trade API uses optional API keys for higher rate limits - see Authentication.
