Query Parameters

senderAddress · string · required

Solana wallet address that will sign and pay for the transaction

paymentCurrency · enum<string>

Payment currency. Defaults to JUP (direct transfer). SOL/USDC/JUPUSD route through an Ultra swap to JUP. Accepted payment currency, given as a token symbol (not a mint address): JUP, SOL, USDC, or JUPUSD. All input currencies are converted to 1000 JUP. JUP transfers directly; SOL, USDC, and JUPUSD are swapped to 1000 JUP via Ultra.

Available options: JUP, SOL, USDC, JUPUSD

Example:

"JUP"
