How much does a flash volume run cost?

The trade price shown on the page. It includes the pool's swap fee on both legs, the lender's fee, the network fee and our 0.2% fee on the volume, the buy and the sell together. The final number can land slightly under the maximum shown, never above it.

Do I need to hold the amount I trade?

No. The amount is borrowed inside the transaction and repaid before it ends. Your wallet only needs the trade price plus a small buffer that comes straight back.

What happens if the transaction fails?

Nothing. Solana transactions are atomic: if the repayment or either swap fails, the whole transaction is rejected, no fee is charged and your balance does not move, apart from the network fee of a transaction that was included and reverted.

Tokens with a SOL-priced pool on PumpSwap, Raydium, Orca or Meteora. Pump.fun tokens still on the bonding curve and Token-2022 mints with transfer fees or hooks are not supported.

Why does my wallet show a warning?

The transaction calls a lending program and a DEX in one go, a pattern wallets flag by default. Every instruction is visible in the wallet's transaction details, and the page checks the transaction against twenty rules before the wallet opens.

Is there a maximum size?

No limit of ours. The size is what the lender can serve at that moment, which is the figure under the amount field, and Jupiter Lend does not lend more than 15,000 SOL inside one transaction. Nothing asks you to confirm twice.

About this tool

What it does

Runs a buy and a sell of one token, in one pool, inside a single Solana transaction. The pool can live on PumpSwap, Raydium, Orca or Meteora. The size is borrowed for the length of that transaction and repaid before it ends, so you trade an amount you do not hold and pay only what the round trip costs.

How it works

Pick a token, type a size in SOL or USD, read the trade price and sign once. The transaction borrows the size, buys the token, sells it back in the same pool, repays the loan and pays the fee. If any step fails, the whole transaction fails and nothing is charged.

Why use it

Volume that would normally take a large balance takes a small one here. The price you see before signing is the price you pay, the loan never touches your wallet, and every transaction is checked against twenty rules before your wallet opens.

How to run Solana flash volume in 3 steps

Choose the token
Paste the contract address or pick a token from your wallet. The tool lists every pool that trades it against SOL on PumpSwap, Raydium, Orca and Meteora, and you pick one. Tokens with no such pool are declined before you type a size.
Set the size
Type the amount you want to trade, in SOL or in dollars, or tap one of the quick sizes. The buy, the sell and the total volume update every two seconds, together with the single trade price you will pay.
Sign once
Press Buy and sell and approve in your wallet. One signature covers the loan, both swaps, the repayment and the fee. The result screen shows what you paid and your balance before and after.

What is flash volume?

A flash loan is a loan that exists only inside one transaction: the funds are borrowed at the start and must be back, with the lender's fee, before the transaction ends. If they are not, the network rejects the whole transaction as if it never happened. A flash volume run uses that window to buy a token and sell it back in the same pool. Because both swaps happen against the same reserves, the price ends where it started, and the only money that leaves your wallet is the cost of the round trip: the pool's swap fee on each leg, the lender's small fee, the network fee and our fee of 0.2% of the volume, which is the buy and the sell together. The tool computes that total before you sign and shows it as one number.
