- Hyperliquid API outage halted trading for over 30 minutes.
- Frontend crash revealed DeFi’s centralised weak points.
- Automated refunds planned for affected users.
Hyperliquid, a fast-growing decentralised exchange built on its own Layer 1 blockchain, has announced it will compensate users affected by a sudden API outage that disrupted trading activity on Tuesday.
The API outage, which occurred on July 29 between 14:10 and 14:47 UTC, left users unable to close positions, execute trades, or withdraw funds through standard interfaces.
Although the backend of the protocol, including the Hyperliquid DEX, consensus mechanism, and HyperEVM, remained operational, the frontend’s failure highlighted a critical vulnerability in many DeFi systems: their reliance on centralised infrastructure for user access.
The Hyperliquid API crash that froze trading for over 30 minutes
The disruption began shortly after 14:10 UTC, when users started reporting significant delays and errors during trade execution.
By 14:20, the exchange’s front end had effectively frozen, preventing any interaction with the protocol through the mobile app or website.
Hyperliquid later confirmed, in its status page, that the root cause was a massive spike in API traffic, not a hack or security exploit.
The surge overwhelmed the centralised servers responsible for relaying information between the frontend and the decentralised backend.
Despite the DEX continuing to produce blocks and confirm transactions, users saw error messages and were unable to take any action.
This mismatch between what was happening on-chain and what users could see or do through the interface caused widespread confusion.
It also led to price divergences as open positions went unmanaged during volatile moments.
Refunds will be automated, no tickets needed
In response, Hyperliquid has pledged to issue refunds to users who were adversely affected during the outage.
The team announced on both Telegram and Discord that the refunds would be determined through an automated process.
“Refunds will be determined in an automated fashion; impacted users do not need to open a ticket at this time,” the Hyperliquid team stated. They also mentioned that a follow-up update detailing the refund methodology would be shared in the coming days.
This move aims to restore user confidence and ensure fair treatment for those who experienced slippage or losses due to the outage.
Hyperliquid emphasised that only users who encountered execution issues during the specified downtime would be eligible.
Market reaction and user sentiment
Following the outage, the platform’s native token, HYPE, dropped nearly 5%, falling from $45 to a low of $42.43.
It has, however, recovered slightly to $44.87.
The decline in token value underscores the market’s sensitivity to operational disruptions, especially those that affect user access and trust.
While Hyperliquid’s quick response and commitment to refunds may ease some concerns, the event has added to growing scrutiny around DeFi platforms’ dependence on centralised frontend components.
