Jupiter — Solana DEX Aggregator
Jupiter routes swaps across all Solana DEXes (Raydium, Orca, Phoenix…) for best price.
⛽ Gas & Cost — Read This First
- Gas is always paid from wallet SOL balance. No gas sponsorship on Solana.
wallet_sol_transferdoes NOT work for Jupiter — it's for send-SOL only.- Swaps cost ~0.0002–0.001 SOL in fees (priority fee + rent deposit for new token accounts).
- Limit orders cost ~0.002 SOL to create (on-chain account rent).
- Always call
wallet_sol_balance()before operating to confirm SOL > 0.01.
⛔ HARD RULES
- ALWAYS use
ultra/v1/order— NOTswap/v1/quote+swap/v1/swap(deprecated) - Pass wallet pubkey to
jupiter_swaponly when intending to execute — omitting it returns a quote-only result (no transaction), which is correct for price checks - NEVER pass numeric
makingAmount/takingAmount— must be strings or API returns ZodError 400 - NEVER use
/ultra/v1/executefor limit orders — limit orders MUST go throughjupiter_broadcast_tx()(Solana RPC) - NEVER omit user confirmation before executing a swap or limit order
