Selling down a bonding curve
A pump.fun sale pushes tokens back into the curve and takes SOL out of it, so every sale lowers the price the next seller gets. Unwinding thirty wallets in a row walks the curve downward; the review applies each sale to a copy of the live reserves in order and shows both the expected SOL and the worst case after slippage.
Each wallet sends pump.fun's sell instruction with a minimum SOL output. If buyers pull the price below that floor before the sale lands, that one sale reverts with nothing sold, and the wallets after it are re-quoted on the new price.
Cashback coins, rent and the token account
Some pump.fun coins are cashback coins, where part of the trading fee flows back to traders; the tool reads that flag from the curve and passes it to the sell. When a wallet sells its whole balance you can close the empty token account in the same transaction: its rent, around 0.0015–0.002 SOL depending on the token program, goes back to that wallet. If an account refuses to close, the sale still goes through without the close.
After the coin leaves the curve
A completed curve no longer trades. Coins that have graduated are sold on PumpSwap via Jupiter, filtered to pump.fun's AMM only. If graduation happens while your run is in progress, the wallets that haven't sold yet switch over automatically.
What selling costs
pump.fun keeps its fee out of the sale proceeds. SOLTidy's 0.5% is computed on the minimum SOL out, not the optimistic quote, and is paid after the swap from the SOL just received, so a seller only needs a little SOL for the network fee. Across one run the SOLTidy fee stops at 0.1 SOL.
Example: 25 wallets each guaranteed at least 1.2 SOL by their slippage floor return 30 SOL in total. 0.5% of that is 0.15 SOL, so the cap applies and SOLTidy takes 0.1 SOL for the run. Closing the 25 emptied accounts returns roughly 0.04 SOL of rent to the wallets.
Questions & answers
Is there a fee for selling?
0.5% of each sale's minimum SOL out, paid from the proceeds, and at most 0.1 SOL for the whole run. pump.fun's own fee is part of the price.
Do the wallets need SOL before selling?
Only enough for the network fee. SOLTidy's share is paid after the sale from what it returns.
Can I sell only half of every wallet?
Yes: choose a percentage. Each wallet then sells that share of its own balance.
What if the price crashes during the run?
Each sale carries its own floor. A sale that would fill below it reverts unsold; later wallets are quoted on the new price.
Does it close the token accounts?
If you sell everything and leave the option on, the empty account is closed and its rent returns to the wallet in the same transaction.
