Pump.fun now lets creators change fee wallets only once after launch, moving to curb \u201cvamping\u201d on Solana as platform revenue falls and industry figures call for coordinated reform.<\/p>\n
<\/p>\n
Pump.fun, the dominant\u00a0Solana\u00a0(SOL)-based memecoin launchpad, announced a significant protocol change on March 24 that caps creator fee modifications to a single post-launch edit \u2014 a direct response to rampant fee manipulation that has eroded user trust across the platform. The update was announced by co-founder Alon Cohen, known on X as\u00a0@a1lon9<\/a>, in a thread that has since accumulated over 396,200 views, 2,600 likes, and 479 retweets.<\/p>\n The problem, as Cohen explained it, had been structural. Every token deployed on pump.fun carries an assigned Coin Admin who controls the creator fee setup \u2014 who receives the fees, how they are distributed, and in what proportions. Until now, those Coin Admins faced no limits on how many times they could alter those settings. \u201cCoin Admins had free reign to change fee recipients and distribution as much as they desire, which ultimately led to manipulation,\u201d Cohen wrote. The pattern was predictable: a creator would deploy a token with fees directed toward a third-party wallet to build community trust, allow the token to gain traction and generate meaningful fee revenue, then quietly redirect those fees back to themselves. \u201cPeople realize, get frustrated, the coin loses traction and narrative is ruined,\u201d Cohen added.<\/p>\n The fix is relatively simple in mechanism but significant in impact. Under the new rules, every token launches with standard creator fees by default, and the creator is granted exactly one opportunity to redirect those fees to a different wallet. After that single reassignment, the configuration becomes permanent and cannot be altered. \u201cThe result: if the creator redirects fees to another wallet, those settings are locked. If they don\u2019t redirect fees, their one chance to do so can be used later,\u201d Cohen said. All existing coins with active fee distributions have had their settings locked retroactively under the update.<\/p>\n <\/p>\nPump.fun reacts to curb \u2018vamping\u2019<\/h2>\n
