Swap RPC Method

The jup_Swap RPC method generates a serialized transaction for executing token swaps based on a provided quote. This endpoint offers advanced options such as dynamic slippage, fee configuration, and compute unit prioritization for optimal transaction execution.

Request Parameters

The request parameters are included in the params property of the RPC request body. Below is the interface definition and detailed description of each parameter.

Request Interface: IGetSerializedSwapTransactionRequest

Field	Type	Required	Default	Description
quoteResponse	any	Yes	None	The quote response received from the quote API endpoint.
userPublicKey	string	Yes	None	The public key of the user executing the swap.
wrapAndUnwrapSol	boolean	No	false	If true, wraps or unwraps SOL as required for the swap.
feeAccount	string	No	None	Account to receive platform fees, if applicable.
dynamicComputeUnitLimit	boolean	No	false	Enables dynamic adjustment of compute unit limits for the transaction.
prioritizationFeeLamports	string, number	No	None	Fee in lamports for transaction prioritization.
dynamicSlippage	{ maxBps: number }	No	None	Dynamic slippage configuration. maxBps specifies the maximum slippage in BPS.
asLegacyTransaction	boolean	No	false	If true, generates a legacy transaction instead of a versioned transaction.
computeUnitPriceMicroLamports	number	No	None	Price per compute unit in micro-lamports for prioritization.
computeUnitLimit	number	No	None	The maximum compute units allocated for the transaction.
feeBps	number	No	None	Fee in BPS deducted during the swap.
