Fees

Everything you pay, published before you fund an agent. No deposit fee, no withdrawal fee, no fee on failed or unfilled orders. Paper mode is labelled and charges nothing.

Kestrel fee schedule

Kestrel trade fee	0.50% of the quote side of every confirmed fill
Deposit fee	none
Withdrawal fee	none
Failed, expired, rejected or unfilled orders	no Kestrel fee (network fee may still apply to a failed transaction)
Paper mode	labelled as paper, charges nothing
Subscription	none. Rules mode and AI mode both pay only the trade fee; any paid tier would be announced here before it applies.

Worked example: a 1 SOL buy on a venue charging a 1.00% fee

Trade size: 1 SOL
Venue fee (1.00%, paid to the venue, not to Kestrel): 0.01 SOL
Kestrel trade fee (0.50%): 0.005 SOL
Network fee (incl. priority, estimated): 0.00001 SOL
Total cost on top of the trade: 0.01501 SOL

Venue fees vary by venue and pool; the exact fee lines for each order are shown on the order page, marked estimated until the transaction confirms.

What Kestrel never charges

No deposit fee. Transfers into a trading wallet are plain SOL transfers.
No withdrawal fee (0 bps). Withdrawals go to your sign-in wallet; you pay only the network fee of that transfer.
No fee on failed, expired, rejected, no-route or unfilled orders. The Kestrel fee applies to confirmed fills only, on the quote side.
Paper mode is labelled as paper everywhere it appears and charges nothing.
No subscription. Rules mode and AI mode both pay only the trade fee. A paid tier for extra features, if one is ever added, is announced on this page before it applies.

Venue fees (paid to the venue, not to Kestrel)

Each venue charges its own fees inside the swap. The quote lists them per order as estimated lines; after confirmation they are replaced with the actual amounts parsed from the transaction.

Venue	Fees
Pump.fun bonding curve	Protocol fee plus a creator fee, both set by Pump.fun's global config and charged on the SOL side of each trade. Shown as venue-protocol and venue-creator lines.
PumpSwap	LP fee, protocol fee and creator fee, per Pump.fun's PumpSwap config. Shown as venue-lp, venue-protocol and venue-creator lines.
Raydium LaunchLab (Stonk.fun)	Protocol fee, platform fee (Stonk.fun's platform config charges 1%), and a creator fee, all read from the pool's config on-chain.
Raydium CPMM	The pool's fee tier. LaunchLab graduations land on the 0.25% tier; other pools can differ and the actual tier is read from the pool.
Meteora Dynamic Bonding Curve	Per-config: each launch config sets its own base fee and optional dynamic fee. Read from the config account at quote time.
Meteora DLMM	Dynamic fee: a base fee plus a volatility component that rises when the price moves fast. The quote shows the fee at that moment.
Meteora DAMM v2	Per-pool fee set when the pool was created, read on-chain. Graduated DBC launches keep their migration fee settings.
Jupiter aggregator	The fees of whichever pools the route passes through, as reported by the Jupiter quote. Kestrel adds no routing fee.

Network and priority fees

Every Solana transaction pays a base network fee (5,000 lamports per signature) plus an optional priority fee the engine sets from recent fee levels, capped by KESTREL_MAX_PRIORITY_MICROLAMPORTS. Both are shown on each order as a network line, estimated until the transaction confirms and then replaced with the amount actually charged.

A failed transaction that reached the network still pays its network fee; Kestrel charges nothing on it.

Token-2022 tokens with a transfer fee deduct that fee on every transfer. It is shown as a token-transfer-fee line and reduces what you receive; the agent can be told to skip such tokens.
