swap

POST https://lite-api.jup.ag/swap/v1/swap

Request for a base64-encoded unsigned swap transaction based on the /quote response

note

Refer to Swap API doc for more information

Request

application/json

Bodyrequired

userPublicKeystringrequired

wrapAndUnwrapSolboolean

To automatically wrap/unwrap SOL in the transaction
If false, it will use wSOL token account
Parameter will be ignored if destinationTokenAccount is set because the destinationTokenAccount may belong to a different user that we have no authority to close

Default value: true

useSharedAccountsboolean

The default is determined dynamically by the routing engine, allowing us to optimize for compute units, etc
This enables the usage of shared program accounts, this is essential as complex routing will require multiple intermediate token accounts which the user might not have
If true, you do not need to handle the creation of intermediate token accounts for the user
Do note, shared accounts route will fail on some new AMMs (low liquidity token)

feeAccountstring

An token account that will be used to collect fees
The mint of the token account can only be either the input or output mint of the swap
You no longer are required to use the Referral Program
See Add Fees guide for more details

trackingAccountstring

Specify any public key that belongs to you to track the transactions
Useful for integrators to get all the swap transactions from this public key
Query the data using a block explorer like Solscan/SolanaFM or query like Dune/Flipside

prioritizationFeeLamports object

asLegacyTransactionboolean

Builds a legacy transaction rather than the default versioned transaction
Used together with asLegacyTransaction in /quote, otherwise the transaction might be too large

Default value: false

destinationTokenAccountstring

Public key of a token account that will be used to receive the token out of the swap
If not provided, the signer's token account will be used
If provided, we assume that the token account is already initialized

dynamicComputeUnitLimitboolean

When enabled, it will do a swap simulation to get the compute unit used and set it in ComputeBudget's compute unit limit
This incurs one extra RPC call to simulate this
We recommend to enable this to estimate compute unit correctly and reduce priority fees needed or have higher chance to be included in a block

Default value: false

skipUserAccountsRpcCallsboolean

When enabled, it will not do any additional RPC calls to check on required accounts
Enable it only when you already setup all the accounts needed for the trasaction, like wrapping or unwrapping sol, or destination account is already created

Default value: false

dynamicSlippageboolean

When enabled, it estimates slippage and apply it in the swap transaction directly, overwriting the slippageBps parameter in the quote response.
Used together with dynamicSlippage in /quote, otherwise the slippage used will be the one in the /quote's slippageBps
See notes for more information

Default value: false

computeUnitPriceMicroLamportsinteger

To use an exact compute unit price to calculate priority fee
computeUnitLimit (1400000) * computeUnitPriceMicroLamports
We recommend using prioritizationFeeLamports and dynamicComputeUnitLimit instead of passing in your own compute unit price

blockhashSlotsToExpiryinteger

Pass in the number of slots we want the transaction to be valid for
Example: If you pass in 10 slots, the transaction will be valid for ~400ms * 10 = approximately 4 seconds before it expires
