Pump.fun has introduced a restriction limiting token creators to a single post-launch change in fee distribution, after which settings are permanently locked.
The update aims to reduce manipulation and “griefing,” where creators redirect fees after a token gains traction, according to co-founder Alon Cohen.
The change allows one fee redirect per token before locking the configuration, preventing repeated adjustments that could undermine trader trust.
The move builds on earlier updates, including January changes to rebalance incentives and February’s “Cashback Coins” feature, which required creators to choose fee structures at launch.
Previously, while overall fee models were fixed, creators could still change recipient wallets after launch, creating potential transparency issues for traders.
Early community reactions suggest the update may have limited impact, with some users calling it a minor improvement despite acknowledging the platform’s efforts.
The changes come as Pump.fun’s activity declines, with fees falling to $31.8 million in January 2026 from $148 million a year earlier, and trading volume dropping more than 80% over the same period.
