What Flash Volume does

What it does

Flash Volume makes trading volume on a Solana token with SOL you do not hold, in two ways. The Auto bot trades for you from a bot wallet of its own, again and again, at the size and pace you set, until it reaches your target or you stop it. A Single trade is one buy and one sell that you sign yourself. Every trade borrows its size inside one transaction, buys and sells in the same pool and repays the loan before the transaction ends, so only the cost of the round trip is spent.

How the Auto bot works

Load the bot wallet with a little SOL, set the trade size, the time between trades and when to stop, then press Start bot. The bot builds every trade, sends it and checks it on the chain. On a pool that has no lookup table of its own yet, the first start sets one up from the bot wallet, so no manual trade is needed first. Each trade shows up on the chart and in the trade log as it lands, and Stop ends the run whenever you want.

Why use it

Volume that normally takes a large balance takes a small one here, and the bot keeps it going while you are away. The pace is kept to the second. Each trade can come from a new wallet, so DexScreener counts a new maker every time, and whatever stays in the bot wallet can be withdrawn to your own wallet whenever the bot is stopped.

An Auto bot that trades for you. Load a bot wallet once and it keeps trading at your size and pace while you are away.
A fixed size or a range. Every trade can pick a new size between your two numbers, with a recommended band read from the pool's depth.
Pace kept to the second. Choose one wait or a range from 3 seconds to 24 hours, and every gap between two trades stays inside it.
A new maker per trade. New wallet for every trade sends each trade from a wallet of its own and brings every lamport back right after.
Stops on your terms. At a volume target, after a time limit or when you press Stop, and by itself if the bot wallet cannot pay for the next trade or the pool gets too expensive.
Live chart and trade log. The volume climbs toward your target, every point opens a card with that trade, and the log lists each trade with its size, volume and cost.
Your balance goes back to you. Withdraw sends part or all of it only to the wallet you are connected with, whenever the bot is stopped.
No setup trade. On a pool without its own lookup table, the first start sets it up from the bot wallet.
A Single trade when you want one. One transaction and one signature, the full price before you sign, nothing charged if it fails.

Frequently asked questions

It trades from a bot wallet that J Tools opens for you. Each trade borrows its size, buys and sells in the pool you picked and repays the loan in the same transaction. The bot then waits the time you set and sends the next one, until it reaches your target or your time limit, the bot wallet runs short, or you press Stop.

Each trade costs the pool's swap fee on both legs, the network fee and our fee of 0.2% of the volume, at least 0.0005 SOL per trade. The settings show the cost per trade before you start, and the run shows what it has spent so far. With New wallet for every trade on, each trade adds two small network fees.

The bot wallet is opened for you alone. Its key stays encrypted on our server so the bot can sign while you are away, and it signs only for this bot: its trades, its fresh wallets and your withdrawals. Withdraw sends the balance only to the wallet you are connected with, and the bot stops by itself if the pool starts keeping much more of each trade than when you started.

Each trade goes out from a wallet of its own, so DexScreener counts a new maker every time. The bot wallet funds that wallet for the trade and takes everything back right after, including the rent of the accounts it opened. It is not available for tokens that take a transfer tax.

Tokens with a SOL-priced pool on PumpSwap, Raydium, Orca or Meteora, and pump.fun tokens still on their bonding curve, on both tabs. A curve takes only what fits before it completes, and pump.fun keeps about 1.25% on each side of the trade. Token-2022 mints with a transfer fee trade only in pools reached through Jupiter, and mints with a transfer hook are not supported.

No. Every trade borrows its size inside the transaction and repays it before the transaction ends. The bot wallet, or your own wallet on a Single trade, only needs the cost plus a small buffer that comes straight back. Jupiter Lend lends up to 15,000 SOL inside one transaction.

Nothing moves. Solana transactions are atomic: if the repayment or either swap fails, the whole transaction is rejected and no fee is charged, apart from the network fee of a transaction that was included and reverted. If several trades in a row do not land, the bot stops by itself.

It is one round trip that you sign yourself on the Single trade tab. Pick a size, read the trade price and press Buy and sell. One signature covers the loan, both swaps, the repayment and the fee, and the result screen shows what you paid.
