pump.fun cashback explained: where it accrues and how to claim it

The short answer

pump.fun cashback is a cashback coin's creator fee paid back to traders: about 0.30% of your bonding curve volume at the time of writing. It accrues as SOL in your pump.fun volume accumulator and as wrapped SOL in your PumpSwap accumulator's token account until you claim it. New cashback coins can no longer be created, but existing ones still accrue. Claim it from pump.fun's rewards section or in one transaction with SOLTidy's wallet cleanup.

What is pump.fun cashback?

pump.fun cashback is a launch option that sent a coin's entire creator fee to the traders paying it, in proportion to their own trading volume. pump.fun introduced cashback coins in February 2026: a creator chose at launch between keeping creator fees and giving them to traders, and that choice was locked for the life of the coin.

pump.fun's developer documentation describes it plainly: cashback "redirects the creator fee to the users. Each user would get the creator fee on their swap volume as cashback rather than paying that fee to the coin creator." So the rate you earn is whatever the creator fee is for that coin at that moment. At the time of writing, in October 2026, pump.fun's fee page lists:

Where you trade a cashback coin	Creator fee, paid to you as cashback	Cashback on 10 SOL of volume
pump.fun bonding curve	0.30%	about 0.03 SOL
PumpSwap, market cap 420 to 1,470 SOL	0.95%	about 0.095 SOL
PumpSwap, 49,120 to 54,030 SOL	0.30%	about 0.03 SOL
PumpSwap, 98,240 SOL and up	0.05%	about 0.005 SOL

These rows are arithmetic from pump.fun's published tiers, which have changed before. Cashback does not reduce the fee you pay; it returns part of it. The protocol and LP fees are not refunded.

Can new cashback coins still be created?

No. pump.fun deprecated cashback mode in 2026: its developer docs say create_v2 now rejects a request to enable cashback, so no new cashback coins can be launched. pump.fun points creators who want to reward their community to holder rewards coins instead, which set the creator fee aside for holders and pay it out without a claim.

Existing cashback coins are not affected. pump.fun's documentation states they "trade exactly as described", their creator fee "is still routed to the buyer", and accrued cashback "stays claimable". If you still trade cashback coins, you are still earning; if you traded them months ago and never claimed, the cashback is still waiting.

Where does pump.fun cashback accrue?

Cashback accrues in your user volume accumulator, the small account pump.fun and PumpSwap each open for your wallet on your first trade. The two programs store it differently because pump.fun's bonding curve trades native SOL and PumpSwap trades wrapped SOL:

	pump.fun bonding curve	PumpSwap
Account	pump.fun user volume accumulator (seed user_volume_accumulator + your wallet)	wSOL token account owned by the PumpSwap user volume accumulator
Held as	SOL, above the accumulator's rent-exempt minimum	Wrapped SOL
Unclaimed amount	Accumulator's lamports minus its rent minimum	The wSOL balance
Claim instruction	claim_cashback on the pump.fun program	claim_cashback on the PumpSwap program
Paid to	Your wallet, as SOL	Your wSOL account, then unwrapped

The accumulator itself is 137 bytes and holds 0.0013462 SOL of rent at the current rate, which you paid when it was opened. That rent is yours, but it is separate from the cashback. Anything above the rent minimum in the pump.fun accumulator is cashback; the PumpSwap cashback is in the separate wSOL account.

One catch from pump.fun's docs: cashback is credited only when the trade instruction includes your accumulator accounts. Bonding curve buys are handled automatically, but sells and PumpSwap trades need the extra accounts, and if an interface left them out the creator fee went to the creator as usual. If a bot or terminal you used had not updated, some trades may have earned nothing.

How do you check and claim pump.fun cashback?

You check by reading your accumulators and claim by signing the claim_cashback instruction on each program. There are three ways to do it.

1. pump.fun's rewards section. When cashback coins launched, pump.fun pointed traders to the rewards section of their profile in the pump.fun app to claim. At the time of writing that remains pump.fun's own route, and it costs only network fees.
2. The SOLTidy wallet cleanup. Connect to the Solana wallet cleanup on SOLTidy's home page. The "pump.fun rewards" row lists "Cashback · pump.fun" and "Cashback · PumpSwap" separately, next to any creator fees if you also launched coins. One transaction claims all of them: it calls each program's claim_cashback, receives the PumpSwap wSOL into a temporary account and closes it, so everything lands as plain SOL. The fee is 5% of the amount the scan found; anything that accrues between scan and signature comes fee-free.
3. Code. pump.fun's SDKs and docs include the claim instructions, and the newer claim_cashback_v2 is permissionless and also handles USDC-paired coins.

I built SOLTidy, so weigh this accordingly: if cashback is the only thing you want, pump.fun's own claim is cheaper. The cleanup earns its fee when you also want to close empty token accounts, sell dust and clear the rest of the wallet in the same pass. The SOLTidy scan reads only SOL and wrapped SOL cashback, and ignores amounts below 0.00001 SOL, which would cost more to claim than they return.

If a claim does not look right afterwards, the Transaction Decoder shows each balance change. A leftover wSOL balance from a manual PumpSwap claim can be unwrapped with the SOL wrap and unwrap tool; what wrapped SOL is explains why it appears.

How does cashback relate to closing the volume accumulator?

The volume accumulator is both where cashback lives and an account you can close for its rent, so the order matters: claim the cashback first, close the accumulator second. Closing early would leave PumpSwap cashback stranded in a token account that belongs to the closed accumulator, and on pump.fun the cashback is inside the account you are closing.

SOLTidy guards against this. Its Token Account Closer, and the empty-accounts row of the cleanup, skip any accumulator that reports unclaimed cashback or owns a token account with a balance. In a single cleanup run the accumulator is therefore left open while the cashback is claimed; scan again afterwards and it is offered for closing.

Whether to close it at all depends on whether you still trade on pump.fun, because the program recreates the account and charges the 0.0013462 SOL again on your next trade. The full walkthrough, including token accounts and dust from pump.fun coins, is in how to reclaim SOL after pump.fun trades, and I will not repeat it here.

What about PUMP token incentives and holder rewards?

They are separate from cashback, and neither needs the cashback claim. The volume accumulator also has fields for PUMP token volume incentives, but when I checked on October 5, 2026, those incentives were not active on chain. Holder rewards coins, the replacement for cashback coins, are paid out to holders by pump.fun without any claim instruction.

If you launched coins rather than only trading them, the creator side of the same fee is covered in how to claim pump.fun creator fees. A wallet can have both, and the cleanup claims both in the same transaction.

Bottom line

pump.fun cashback is a cashback coin's creator fee returned to traders, 0.30% of bonding curve volume at the time of writing and 0.05% to 0.95% on PumpSwap. It accrues as SOL in your pump.fun volume accumulator and as wrapped SOL in your PumpSwap accumulator's token account. No new cashback coins can be created, but existing ones still pay out, and unclaimed cashback does not expire. Claim it before closing the accumulator, either from pump.fun's rewards section or with the "pump.fun rewards" row of the SOLTidy wallet cleanup for 5%.
