Summary
- Multiple DeFi protocols announced closures in May 2026 after exploits and operational issues struck the sector.
- Full Sail on Sui suffered a $91K oracle exploit that led to its shutdown and full compensation promises for depositors.
- Compound governance proposals on Ethereum advanced deprecation steps for certain assets amid ongoing code and control debates.
Multiple DeFi protocols announced shutdowns in May 2026. ZER0 Network and Everclear disabled deposits and halted block production. Full Sail on Sui followed after an exploit hit its vaults.
These moves add to a pattern of defi shutdowns that highlight ongoing risks.
The closures come as governance activity continues at established protocols like Compound.
Context
DeFi protocols have faced repeated security and sustainability questions since the sector's early growth phase. By 2026 several projects reached points where exploits or operational costs made continuation impractical. Full Sail's case on the Sui network fits this timeline directly.
The incident involved a Switchboard oracle exploit.
An attacker manipulated prices through a compromised signature chain and drained funds from three vaults. Direct liquidity pool positions remained unaffected according to the team.
Details
Full Sail confirmed the loss totaled approximately $91,000. The protocol announced it would wind down operations and compensate all depositors in full. This event marks another entry in the list of defi shutdowns tied to oracle vulnerabilities.

Compound governance moved forward on separate proposals during the same period.
One measure advanced the deprecation of pumpBTC from the cWBTCv3 market on Ethereum. These steps reflect active delegate voting on asset listings and risk parameters.
Defi security 2026 concerns center on oracle integrity and upgrade processes. Full Sail's response included a clear statement that only specific vaults were impacted. The broader set of closures, including ZER0 Network and Everclear, points to similar pressures across different chains.
Outlook
Protocols will continue to face decisions on whether to patch, compensate, or exit after incidents. Observers will watch how remaining teams strengthen oracle setups and governance thresholds in the months ahead.
