Swaps (Jupiter)

You can route spot swaps using Jupiter. In TypeScript, the SDK exposes a JupiterClient plus a convenience driftClient.swap(...) helper.


import { Connection } from "@solana/web3.js";
import { JupiterClient } from "@drift-labs/sdk";
 
const connection = new Connection("<RPC_URL>", "confirmed");
const jupiterClient = new JupiterClient({ connection });

Class JupiterClientReference ↗

Name	Type	Default
`url`	`string`
`connection`	`Connection`
`lookupTableCahce`	`Map<string, AddressLookupTableAccount>`
`apiKey`	`any`
`getHeaders`	`any` Get the headers for API requests, including API key if configured
`getQuote`	`({ inputMint, outputMint, amount, maxAccounts, slippageBps, swapMode, onlyDirectRoutes, excludeDexes, autoSlippage, maxAutoSlippageBps, usdEstimate, }: { inputMint: PublicKey; outputMint: PublicKey; amount: BN; maxAccounts?: number; slippageBps?: number; swapMode?: SwapMode; onlyDirectRoutes?: boolean; excludeDexes?...` Get routes for a swap
`getSwap`	`({ quote, userPublicKey, slippageBps, }: { quote: QuoteResponse; userPublicKey: PublicKey; slippageBps?: number; }) => Promise<VersionedTransaction>` Get a swap transaction for quote
`getTransactionMessageAndLookupTables`	`({ transaction, }: { transaction: VersionedTransaction; }) => Promise<{ transactionMessage: TransactionMessage; lookupTables: AddressLookupTableAccount[]; }>` Get the transaction message and lookup tables for a transaction
`getLookupTable`	`(accountKey: PublicKey) => Promise<AddressLookupTableAccount>`
`getJupiterInstructions`	`({ transactionMessage, inputMint, outputMint, }: { transactionMessage: TransactionMessage; inputMint: PublicKey; outputMint: PublicKey; }) => TransactionInstruction[]` Get the jupiter instructions from transaction by filtering out instructions to compute budget and associated token programs


// Preview a quote before swapping (shape depends on Jupiter route selection).
const quote = await jupiterClient.getQuote({
  inputMint: "<INPUT_MINT>",
  outputMint: "<OUTPUT_MINT>",
  amount: "<AMOUNT_IN_BASE_UNITS>",
});
console.log(quote);

Method JupiterClient.getQuoteReference ↗

Parameters:

Name	Type	Default
`__0`	`{ inputMint: PublicKey; outputMint: PublicKey; amount: BN; maxAccounts?: number; slippageBps?: number; swapMode?: SwapMode; onlyDirectRoutes?: boolean; excludeDexes?: string[]; autoSlippage?: boolean; maxAutoSlippageBps?: number; usdEstimate?: number; }` the mint of the input token

Returns:

Promise<QuoteResponse>


// Assumes `driftClient` is subscribed.
const txSig = await driftClient.swap({
  jupiterClient,
  inMarketIndex: 0,  // e.g. USDC
  outMarketIndex: 1, // e.g. SOL
  amount: driftClient.convertToSpotPrecision(0, 10), // 10 USDC (example)
  slippageBps: 50,
  onlyDirectRoutes: false,
});
 
console.log(txSig);

Method DriftClient.swapReference ↗

Parameters:

Name	Type	Default
`__0`	`{ swapClient?: UnifiedSwapClient \| SwapClient; jupiterClient?: JupiterClient; outMarketIndex: number; inMarketIndex: number; outAssociatedTokenAccount?: PublicKey; ... 8 more ...; quote?: UnifiedQuoteResponse; }` swap client to find routes and instructions (Titan or Jupiter)

Returns:

Promise<string>
