Aggregator Usage

These snippets demonstrate how you can use the TradeAggregatorV2 class to

1. query coin info
2. query quotes for a particular pair
3. perform swap

// compute a list of quotes (ordered by output), for fromSymbol -> toSymbol
const listQuotes = async (fromSymbol: string, toSymbol: string, inputUiAmt: string) => {
  const { client } = getAptosClient();
  const agg = await TradeAggregatorV2.create(client);
  const xCoinInfos = agg.coinListClient.getCoinInfoBySymbol(fromSymbol);
  const yCoinInfos = agg.coinListClient.getCoinInfoBySymbol(toSymbol);
  const inputAmt = parseFloat(inputUiAmt);
  const quotes = await agg.getQuotes(inputAmt, xCoinInfos[0], yCoinInfos[0], {
    split: true,
    considerGasWhenSorting: true,
    allowHighGas: true
  });
  for (const quote of quotes) {
    console.log('###########');
    quote.route.debugPrint();
    console.log(`Quote input: ${quote.quote.inputUiAmt}`);
    console.log(`Quote output: ${quote.quote.outputUiAmt}`);
  }
};

// send a transaction to swap "inputUiAmt" of "fromSymbol" to "toSymbol"
const swap = async (fromSymbol: string, toSymbol: string, inputUiAmt: string) => {
  const { client } = getAptosClient();
  const agg = await TradeAggregatorV2.create(client);
  const xCoinInfos = agg.coinListClient.getCoinInfoBySymbol(fromSymbol);
  const yCoinInfos = agg.coinListClient.getCoinInfoBySymbol(toSymbol);
  const inputAmt = parseFloat(inputUiAmt);
  const quotes = await agg.getQuotes(inputAmt, xCoinInfos[0], yCoinInfos[0], {
    split: true,
    considerGasWhenSorting: true,
    allowHighGas: true
  });
  if (quotes.length === 0) {
    console.log('No route available');
    return;
  }
  const payload = quotes[0].route.makeSwapPayload(inputAmt, 0);
  await sendPayloadTx(client, account, payload as TxnBuilderTypes.TransactionPayloadEntryFunction);
};

You can find more sample code that uses TradeAggregator in src/tools/index.ts.
