Traders on the Axiom crypto platform temporarily lost the ability to sell meme coins due to a sudden API update on the pump.fun service, which caused a massive technical failure. The incident occurred on August 28, 2025, and triggered significant panic among users, as the sell button in the Axiom app stopped functioning, making it impossible to close positions.

Causes of the Failure and User Reactions
The platform administrators promptly reported the issue on their official Discord channel, emphasizing that sales were currently only possible directly on the pump.fun website. The number of complaints and support requests surged, with users demanding compensation for financial losses en masse.
“If you need to sell, you can only do it on the pump.fun website.”
It turned out that pump.fun had implemented significant changes to its API without notifying partner trading services, resulting in all bots losing access to the meme coin selling function. As a result, trading was only available on pump.fun itself.
Restoration of Operations and Market Consequences
After a series of complaints and active discussions on social media, the pump.fun team was forced to roll back the integrated API update, allowing Axiom to restore its selling functionality. However, the platform’s administration continued to process numerous refund requests for a long time and attempted to reassure customers.
Axiom operates on the Solana blockchain, with its development supported by YCombinator. Since its launch in February 2025, the platform quickly reached a high level—by May, its revenue from fees exceeded $100 million.
Meanwhile, pump.fun recently regained its leadership among launchpads for meme coins in the Solana ecosystem, holding over 93% of the market share, remaining an essential part of the infrastructure for traders. However, such incidents highlight the risks associated with reliance on a single platform.
