1What Feeback is
Feeback is a bot for pump.fun coins, built by PUMP V2. A coin's dev picks where its creator fees go: their own wallet, the coin's holders, buybacks that deepen the coin's pool, or buybacks that burn. The coin gets its own bot wallet, which runs that mix on chain and logs every move publicly.
It works on any pump.fun Creator Fee coin, on any pair pump allows: SOL, USDC, PUMP, PUMP V2 or another pump coin. Coins set to pump's own Holder Rewards option can't use it, because their fees already go to holders through pump.
2Where the fees go
Pump's split, set once
Pump.fun can split a coin's creator fees between several wallets. Feeback uses three:
- The dev wallet: 5% to 90%, the dev's pick.
- The coin's bot: the rest.
- Feeback: 5%, or 2% on PUMP and PUMP V2 pairs. Of a 5% cut, 4% goes to PUMP V2 and 1% back to the PUMP pairs (sections 5 and 6).
For example 25 / 70 / 5. Pump locks this split once it's set. Nobody can change it afterwards, us included.
The mix, change it any time
Together with the dev's share, what the bot receives is split four ways:
- Creator rewards. Sent to the dev wallet. Never lower than the dev's pump split, since that part goes to the dev directly.
- Holder rewards. Paid to every holder by how much they hold, or only to the top 100. Pools, the bonding curve, lockers, burn addresses, the dev and the bot are left out.
- Buyback + LP. Half buys the coin, then both halves go into the coin's PumpSwap pool and the LP tokens are burned. That liquidity is locked for good.
- Buyback + burn. Buys the coin and burns it.
The four parts add up to 95%. Feeback's 5% makes 100. On PUMP and PUMP V2 pairs Feeback takes 2% instead, and the other 3% lands in the bot and follows the mix.
Before a coin bonds it has no pool yet, so the LP part goes where the dev picked: burn, holders or creator. Everything is paid in the coin's pair: SOL for SOL coins, PUMP for PUMP coins, and so on.
3Payouts and timing
- Each coin's bot checks every 10 minutes.
- New fees wait on pump until they reach the coin's payout line. The dev picks it, from $5 up (it starts at $100). Then the bot has pump pay out everything waiting. Pump pays the dev, the bot and PUMP V2 their shares in the same transaction.
- Quiet coins: if fees sit under the line for 7 days, they're paid out anyway, so nothing waits forever.
- Each part only runs once its amount is worth a transaction. Smaller amounts wait for the next payout.
- On token pairs, a holder who has no token account for the pair yet is only paid once their share is worth opening one.
4Gas
The bot pays its own Solana fees from SOL the dev puts in it at setup (0.02 to 0.1 SOL), and the dev can top it up any time in Feeback Manager. Each coin's page shows its gas and about how many runs are left. If it runs low, the bot pauses until it's topped up.
5Feeback's cut
- 5% of every coin's creator fees, or 2% on PUMP and PUMP V2 pairs. Pump pays it straight to Feeback's cut wallet as part of the split.
- The cut wallet turns what it gets into PUMP once it's worth $2 (SOL and other tokens are swapped). PUMP V2 from PUMP V2-paired coins is never sold: it goes on as it is.
- 4% of the 5% (80% of the cut) goes to the PUMP V2 bot, which uses it for PUMP V2's buybacks and liquidity.
- 1% of the 5% (20% of the cut) goes into the PUMP pairs pool, below.
On a PUMP-pair coin that pays 2%, it's 1.6% to PUMP V2 and 0.4% to the PUMP pairs.
6The PUMP pairs pool
- 1% of every coin's creator fees (20% of Feeback's cut), from every coin on every pair, is set aside.
- It's paid back only to coins paired with PUMP or PUMP V2, by how much each earned: a coin's share is its creator fees (in dollars) since the last round, out of all PUMP-pair coins' fees.
- It lands in the coin's bot and goes to the part of the mix its dev picked: creator, holders, LP or burn (burn if they didn't pick).
- A round is paid once the pool is worth $10, or once a day if it's worth $2.
- PUMP V2-paired coins are paid in PUMP V2: from the pool's PUMP V2 first, then PUMP swapped to PUMP V2 (a buy). PUMP V2 is never sold to pay it.
- Every round is on the cut wallet's public log and on each coin's ledger.
7Who controls what
- Only the dev wallet can set or change a coin's settings. Settings are a note signed by the dev wallet and posted on chain, and the bot reads them from there.
- The mix, the payout line and who gets holder rewards can change any time in Feeback Manager, with one signature.
- Pause: new fees wait on pump until the bot runs again.
- Close: the bot does one last cycle, sends everything left back to the dev (gas included), and from then on passes the coin's share of new fees straight to the dev.
- Pump's split stays as it was set, forever.
8Launching with Feeback
PUMP V2's launcher creates the coin on pump.fun with pump's own program and sets up Feeback in the same approval, so the split is in place before anyone can trade. You pick the pair, a dev buy, pump's own options (Mayhem mode on SOL and USDC pairs, the creator fee on pairs that allow it), a banner and your mix. Creator rewards go to the creator, pump's "Creator" option, so Feeback can split them.
9Safety
- We never see or hold your dev wallet's keys. You sign in your own wallet; the pages build every transaction in your browser and check it against the chain before you sign.
- Each coin's bot is its own wallet, run by the Feeback server. It only holds the coin's fees on their way through, plus its gas.
- The pages check the server: if it reports a different PUMP V2 cut wallet than the one built into the page, they refuse to sign anything.
- Everything is public. Every move a bot makes is on its coin's ledger, with the transaction.
- Memecoins are risky and Feeback doesn't change that. Nothing here is financial advice.
10Addresses
Every Feeback setup mentions the registry address. That's how the bots find new coins.
11The numbers on the site
- Prices and market caps come from DexScreener, or from the coin's own bonding curve before DexScreener lists it.
- Dollar figures use today's price of the coin's pair unless a row says otherwise.
- "Fees paid out" is the whole payout from pump: the dev's share, the bot's share and PUMP V2's share together.
