Mass Panic and Trader Complaints Following the Glitch
On August 28, 2025, users of the Axiom trading platform found themselves in a difficult situation due to an unexpected technical issue. As a result of the API update on pump.fun, the sell button in the Axiom app stopped working, depriving traders of the ability to close positions with meme coins. This triggered a wave of outrage among customers, who began flooding the support service with demands for compensation for their losses.
Confirmation of the issue appeared in the official Discord channel of the platform, where administrators stated:
“If you need to sell, you can only do it on the pump.fun website.”
Within a few hours after the incident, hundreds of users sent complaints about their inability to sell their tokens, and the number of requests to the support service significantly exceeded the usual level.
Causes of the Glitch and Market Consequences
The Axiom team explained that the technical difficulties arose due to unexpected changes in the pump.fun API, which had not been previously coordinated with the developers of trading bots:
“pump.fun made radical changes without notifying the trading bots,” they reported.
Due to this glitch, all trading bots lost the ability to execute sell transactions, and the only alternative for traders was direct selling on the pump.fun website. This situation sparked active discussions on social media, where users spread information about the sale block.
After several hours of downtime, pump.fun reversed the changes, and the selling function on Axiom was restored. However, the platform’s administration continued to receive numerous requests for refunds and tried to reassure traders.
Axiom, which operates on the Solana blockchain and is supported by YCombinator, entered the market in February 2025. Within just four months, its revenue from fees exceeded $100 million. Meanwhile, pump.fun, which recently reclaimed over 93% of the Solana meme coin launchpad market, remains a key player for traders. At the same time, such incidents illustrate the risks arising from dependence on a single platform.
