• yarn add @socket.tech/socket-v2-sdk

  or

• npm i @socket.tech/socket-v2-sdk

In summary:

• Initialise the sdk:

  const socket = new Socket({ apiKey: API_KEY });

• Retrieve the token lists

  const tokenList = await socket.getTokenList({
    fromChainId: 1,
    toChainId: 137,
  });
  
  // tokenList.from has list of from tokens
  // tokenList.to has list of to tokens

• Create a path

  const path = new Path({ fromToken, toToken });

• Get quote

  const quote = await socket.getBestQuote({
    path,
    amount,
    address,
  }, { ... Any quote preferences here })

• You have 2 options for executing a quote. Managing the steps yourself or connecting a web3 provider.

• Connecting web3 provider:

  const provider = new ethers.providers.Web3Provider(window.ethereum); // Or use wallet provider like onboard, web3modal, web3react etc.
  const connectedSocket = socket.connect(provider);
  await connectedSocket.start(quote, {
    onTx: (tx) => {
      console.log('Executing transaction', tx);
      return (tx) => {
        console.log('Done transaction', tx);
      }
    }
    ... // Other callbacks
  });

• Handle the steps manually

  const execute = await socket.start(quote);
  let next = await execute.next();
  
  while (!next.done && next.value) {
    const tx = next.value;
    const approvalTxData = await tx.getApproveTransaction();
    // ... if there is approval send the approve and wait
  
    const sendTxData = await tx.getSendTransaction();
    // ... send the tx and execute next
  
    next = await execute.next(sendTx.hash);
  }

All api functions are available through the typescript client

const socket = new Socket(API_KEY);
const activeRoute = await socket.client.routes.getActiveRoute({ activeRouteId: 1234 });
