const quote = async () => {
  const swap = new Swap(connection);
  const { out: outAmount, impact } = await swap.getQuote(
    new PublicKey("So11111111111111111111111111111111111111112"), //SOL
    new PublicKey("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"), //USD
    1000000n
  );
  console.log(`out: ${outAmount} ${impact}`);
  return { outAmount, impact };
};
quote();

Get Minimum Amount Out and Swap Tokens

import { Connection } from "@solana/web3.js";
import { Swap } from "goosefx-ssl-sdk";

const connection = new Connection(
  "https://api.mainnet-beta.solana.com/",
  "finalized"
);

async function main() {
  const wallet = new Keypair();
  const swap = new Swap(connection);

  const ixs = await swap.createSwapIx(
    new PublicKey("So11111111111111111111111111111111111111112"),
    new PublicKey("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"),
    100000n, // 0.0001 SOL
    100n, // 0.0001 USDC
    wallet.publicKey
  );

  let tx = new Transaction();
  for (const ix of ixs) {
    tx.add(ix);
  }

  // Send out the tx use browser wallet or keypair
}

main();

Get Status of the SSL Pool

import { Connection } from "@solana/web3.js";
import { SSL, ADDRESSES } from "goosefx-ssl-sdk";
import { NATIVE_MINT } from "@solana/spl-token";

const connection = new Connection(
  "https://api.mainnet-beta.solana.com/",
  "finalized"
);

//get the pool status for SOl native token
async function getSolPoolStatus() {
  const ssl = (await SSL.loadByMint(
    connection,
    ADDRESSES["MAINNET"].GFX_CONTROLLER,
    NATIVE_MINT
  ))!;
  const isSuspended = ssl.suspended;
  return isSuspended;
  // interprete the meaning from this: if true, the pool have been suspended and all txns to it will fail, if false the pool is active
}

getSolPoolStatus();

Build

yarn build: this will output the bundled js in the dist folder.

Technical Notes

Stability of the Functions

We hope you find the tools we used to build our API useful in the ts/src folder. Due to our on-going development of the GooseFX platform api, we cannot guarantee the stability of the SDK swap beyond 1 SOL. The SDK will be updated in later version to increase the compute units.
