The decentralized finance platform Flying Tulip has introduced a withdrawal circuit breaker to address a surge in vulnerability exploits, which caused over $600 million in DeFi losses in April alone.
Under this protocol, document the new security feature called the "circuit breaker" will slow down or limit withdrawals during a surge in fund outflows. It can also prevent sudden liquidity depletion following a hack or panic, giving developers time to identify the issue and minimize losses.
The system will not immediately shut down all services but will gradually slow down processing. For example, some withdrawals may fail and require retrying, while others will enter a queue, especially for stable assets like ftUSD (the platform’s native stablecoin). Additionally, users can view the system’s real-time status through a public status page.
Importantly, the system is designed with a fail-open architecture, so even if a security layer fails, transactions will continue—albeit at a slower pace and with stricter controls.
The statement also noted that this will not affect user trading, and most users will not even notice the existence of the circuit breaker mechanism. Deposit functions will always operate normally, and standard withdrawal processes can be completed without issue. Withdrawals may take several hours to process only in the event of a sudden surge in withdrawal requests—a scenario that is unlikely to occur under normal circumstances.
Flying Tulip and the April DeFi Vulnerability Wave
This announcement comes amid a surge in DeFi hacks, with over $600 million lost in April alone. Nearly 95% of these losses stemmed from two major incidents: the Drift Protocol hack (approximately $280 million lost) and the KelpDAO hack (approximately $290 million lost).
KelpDAO particularly triggered panic throughout the market, squeezing liquidity on lending platforms, enabling protocols such as Aave to freeze the market.
To date, DeFi losses in 2026 have approached $1 billion, with April being the worst month so far.
As for Flying Tulip itself, it is a brand-new DeFi ecosystem launched in February 2026. The platform aims to integrate yield generation, lending and trading tools, along with ftUSD.
Flying Tulip attracted attention earlier this year after securing hundreds of millions of dollars in funding and launching structured products designed to utilize capital more efficiently.
