Jupiter

Jupiter V6 is natively supported in the SDK. Utility methods are provided to easily get swap quotes, build and send the transactions needed to perform swaps. Jupiter is the key liquidity aggregator for Solana, offering the widest range of tokens and best route discovery between any token pair. For a detailed description refer to the official Jupiter documentation.

​
Perform a Swap

Create an IDex istance, providing a default account: 
IDexAggregator dex = new JupiterDexAg(Web3.Account);
Create an IDex istance: 
TokenData tokenA = await dex.GetTokenBySymbol("SOL");
TokenData tokenB = await dex.GetTokenBySymbol("USDC");
Get a swap quote for 1 SOL: 
SwapQuoteAg swapQuote = await dex.GetSwapQuote(
    tokenA.MintAddress,
    tokenB.MintAddress,
    DecimalUtil.ToUlong(1, tokenA.Decimals)
);

var quote = DecimalUtil.FromBigInteger(swapQuote.OutputAmount, tokenB.Decimals);
Debug.Log(quote); // Amount of espected USDC token to receive
Display the route path: 
Debug.Log(string.Join(" -> ", swapQuote.RoutePlan.Select(p => p.SwapInfo.Label)));

// Lifinity V2 -> Whirlpool
Create the swap transaction: 
Transaction tx = await dex.Swap(swapQuote);
Sign and send the swap transaction: 
await Web3.Wallet.SignAndSendTransaction(tx);

​
Use the Jupiter Payments API

The Jupiter Payments API is also available, enabling you to utilize Jupiter + SolanaPay for facilitating user payments with any SPL token, allowing pricing in USDC or other tokens. Create an IDex istance, providing a default account: 
IDexAggregator dex = new JupiterDexAg(Web3.Account);
Create an IDex istance: 
TokenData tokenA = await dex.GetTokenBySymbol("SOL");
TokenData tokenB = await dex.GetTokenBySymbol("USDC");
Get a swap quote for the amount of SOL needed for obtaining 5 UDSC: 
SwapQuoteAg swapQuote = await dex.GetSwapQuote(
    tokenA.MintAddress,
    tokenB.MintAddress,
    DecimalUtil.ToUlong(5, tokenB.Decimals),
    SwapMode.ExactOut
);

var quote = DecimalUtil.FromBigInteger(swapQuote.InputAmount, tokenA.Decimals);
Debug.Log(quote); // Amount of espected SOL token to pay
Create the swap transaction: 
Transaction tx = await dex.Swap(swapQuote);
Sign and send the swap transaction: 
await Web3.Wallet.SignAndSendTransaction(tx);
