Every small fish you hold, priced to the lamport.
Sprat is a trading desk for pump.fun coins. It shows what your whole bag would actually pay if you sold it now, lets you buy and sell any coin before or after it graduates, sells everything in one go — and hands back the rent your dead coins are sitting on.
What is trading right now.
Straight from pump.fun's own list. Open any of them to see it priced from the chain and trade it.
One desk for the whole bag.
Four things pump.fun's own site makes you do one coin at a time, or not at all.
The honest price
Not the last trade times your balance. What selling all of it pays right now, after pump.fun's fees, worked out with the same integer arithmetic the program uses.
Buy and sell anything
On the bonding curve or after graduation to PumpSwap, SOL or token quoted. Every trade is simulated first, so you see the exact result before you sign.
Sweep
Sell every coin you pick, close each emptied account and take its rent back — about 0.002 SOL a coin. Dead coins can be burned and closed for the rent alone.
Launch
Create a coin on pump.fun itself — picture, name, ticker, a first buy — in one transaction from your wallet. It is a pump.fun coin like any other, you are its creator.
Nothing between you and pump.fun.
Sprat has no contract and no custody. It reads the chain, builds pump.fun's own instructions with pump.fun's published SDK, and hands them to your wallet.
- Connect any Solana wallet.
Phantom, Solflare, Backpack — anything that speaks the Wallet Standard. Sprat sees your address, never your keys. - Sprat reads your token accounts.
Every coin with a pump.fun bonding curve is priced from that curve, or from its PumpSwap pool once it has graduated. - Every transaction is simulated before you sign.
The desk shows the coins or SOL the simulation says you will get, and the fee. If the simulation fails, nothing is put in front of you. - Your wallet signs; the trade goes straight to pump.fun.
With a minimum you will accept, so a price that moves too far makes the program refuse rather than fill you badly.
Checked against live coins, not a mock.
The tests have not been run for this build.

Before you connect.
Does Sprat hold my coins or my SOL?
No. There is no Sprat contract. Each trade is a transaction from your wallet straight to pump.fun's program (or PumpSwap's, after graduation). You read it in your wallet before you sign it.
What does it cost?
Sprat takes nothing. pump.fun charges its own trading fee (the program sets it; as of 05 Nov 2026, 0.95% to the protocol and 0.3% to the coin's creator on the curve), and Solana charges a network fee of a fraction of a cent plus whatever priority fee you choose.
Why is the value lower than pump.fun shows?
pump.fun shows the last price times your balance. Selling a lot of a thin coin moves the price as you sell, and the fee comes off the top. Sprat shows what the sale actually pays, which is the only number you can spend.
What is the "rent" I get back?
Every token you hold lives in its own token account, and Solana makes you deposit about 0.002 SOL to keep each one open. Selling a coin leaves the empty account — and your deposit — behind. Sprat closes it in the same transaction and the deposit comes back to you.
Can it sell a coin that has graduated?
Yes. Once a coin's curve completes, pump.fun moves its liquidity to a PumpSwap pool, and Sprat trades it there with PumpSwap's own instructions.
What does "burn and close" do?
For a coin nobody will buy, Sprat can burn your balance and close the account, so the rent comes back. Burning is permanent; the desk asks before it does it and never burns a coin that still has a buyer unless you tell it to.
Is it audited?
Sprat has no contract to audit: the programs that hold value are pump.fun's. The desk itself is new software. Its quotes and transactions are tested against live coins (see above), but you should still read each transaction in your wallet.
