Fulcrom Finance, a decentralized perpetual exchange built on the Cronos blockchain, shifted into degraded trading mode after its primary price data source, Pyth Network, suffered a significant outage. The platform urged users to avoid opening new positions while the feed was down.

The disruption began around 02:58 UTC on May 22, hitting Pyth’s Pythnet and Hermes infrastructure and lasting over four hours. For a platform that processes leveraged trades using real-time pricing, four hours without reliable data is less “minor hiccup” and more “the lights are flickering in the operating room.”

What actually broke

Pyth Network serves as a massive price data aggregation layer, pulling information from institutional publishers and distributing it across more than 100 blockchains. The network supports over 3,000 individual price feeds and works with more than 130 data publishers across 114 chains. It is, in other words, plumbing that a lot of DeFi depends on.

When that plumbing stopped flowing, Fulcrom was one of the platforms caught without water. The exchange relies on Pyth’s real-time asset pricing to power its low-fee perpetual trading model and liquidity pools. Without accurate price data, executing leveraged trades becomes a game of blindfolded darts, which is why the team moved quickly to flag the degraded state.
