Kanalabs aggregator sdk

Description

• SDK to interact with all Amm platform available on Aptos and Solana Blockchain

SDK Usage

1. Solana
2. Aptos

Installation

npm i kana-aggregator-sdk

Testnet TokenList

  //only for testnet
  import { getTokenByChainID } from 'kana-aggregator-sdk'
  //chainID 1 for solana and 2 for Aptos
  let chainId = 2
  let networkId = 2
  const devTokens = getTokenByChainID(chainId,networkId);  //networkId is 1 for mainnet tokens and 2 for testnet

Aptos Aggregator

Using SDk

    import { getRoutesForSwap, getSwapIx} from 'kana-aggregator-sdk'
    import * as aptos from 'aptos';
    const NODE_URL = "https://fullnode.testnet.aptoslabs.com"; //RPC URL

    let client = new aptos.AptosClient(NODE_URL);

    const chainId = "aptos";
    const networkId = 2 // 1 for mainnet
    const inputCoin = "0x1::aptos_coin::AptosCoin";
    const outputCoin = "0x43417434fd869edee76cca2a4d2301e528a1551b1d719b75c350c3c97d15b8b9::coins::USDT";
    inputAmount = 100000000;
    const slippage = 1; // Percentage


    async function swap(){
        // Get best routes for the given pair
        let routeData = await getRoutesForSwap(
            chainId,
            inputCoin,
            outputCoin,
            inputAmount,
            slippage,
            //Fee account has to be initialized before collecting fee

        );

        let optimalRoute = routeData.routes[0]
        // Get The transaction payload for transaction
        const txnPayload = await getSwapIx(
            chainId,
            optimalRoute
        )
        const txnRequest = await client.generateTransaction(
            account.address(),
            txnPayload,
            {
                max_gas_amount: "20000",
                gas_unit_price: "100",
                expiration_timestamp_secs: `${new Date().getTime() / 1000 + 60}`
            }
        );
        <!-- const signedTxn = await client.signTransaction(account, txnRequest);
        const res = await client.submitTransaction(signedTxn);
        await client.waitForTransactionWithResult(res.hash);
        console.log(res.hash); -->
    }

    swap()

Using API's

let swapQuote = 'https://ag.kanalabs.io/stage-devquote/swapQuote'
let swapIx = 'https://ag.kanalabs.io/stage-devix/swapInstruction'

//For example we have used AXIOS and JS you can use your preferred package or language

 const response = await axios.get(swapQuote, {
      params: {
        chainId: "aptos",
        networkId: 1, // 2 for testnet
        inputCoin: inputCoin,
        outputCoin: outputCoin,
        inputAmount: inputAmount,
        slippage: slippage ? slippage : null,
        directRoutes: directRoutes, //optional currently not suported 
      },
  })

let swaproutes = response.data

const txnPayload = await axios.post(swapIx, {
    networkId: 1, 2 for testnet
    chainId: "aptos",
    swapRoute: swaproutes.routes[0] ,
})
 const txnRequest = await client.generateTransaction(
      account.address(),
      txnPayload,
            {
                max_gas_amount: "20000",
                gas_unit_price: "100",
                expiration_timestamp_secs: `${new Date().getTime() / 1000 + 60}`
            }
        );
        <!-- const signedTxn = await client.signTransaction(account, txnRequest);
        const res = await client.submitTransaction(signedTxn);
        await client.waitForTransactionWithResult(res.hash);
        console.log(res.hash); -->
