Circle’s chief strategy officer Dante Disparte has responded to an estimated $270 million exploit on Solana-based Drift Protocol, defending how USDC is governed while calling for stronger legal and technical safeguards for decentralized finance (DeFi).
On April 1, an attacker reportedly seized Drift’s governance keys, drained an estimated $270 million to $285 million in assets, rapidly swapped much of the proceeds into USD Coin (USDC), and bridged more than $230 million to Ethereum via Circle’s Cross-Chain Transfer Protocol. On-chain analyst ZachXBT argued that Circle had “roughly six hours” to freeze the stolen USDC but “took no action,” increasing scrutiny of how centralized issuers respond during live attacks.
In an X statement and follow-up commentary, Disparte said Circle cannot and will not freeze USDC based on social-media pressure or unilateral discretion. “USDC freezing is only executed under legal mandate — not unilaterally,” he said, describing the approach as a matter of due process and financial privacy rather than operational convenience.
Disparte also argued that it is “indefensible and untenable” for tools and software to be co-opted by bad actors without being checked, while warning that unchecked intervention by issuers could create risks for legitimate users.
Disparte used the Drift exploit to urge U.S. lawmakers to move faster on the GENIUS Act and the broader market-structure CLARITY Act, arguing both are needed “before the next major security incident.”
He previously described the GENIUS Act as “the most significant US law for innovation since the 1990s,” saying it would require full-reserve backing, monthly disclosures, and robust supervision for dollar stablecoin issuers. He also said the CLARITY Act—currently moving through Congress—would extend that framework to trading venues and intermediaries, clarifying when and how assets like USDC can be frozen or clawed back after hacks.
Beyond Washington, Disparte urged DeFi teams to adopt safeguards common in traditional financial markets. He called for on-chain “circuit breaker mechanisms” that can automatically halt trading or withdrawals under abnormal conditions.
He argued that “risk controls, not improvisation on X, should decide how a $270 million exploit plays out.” With Drift still assessing losses across USDC, BTC, SOL, and other assets, the incident is being framed as a live test of how stablecoin issuers, protocols, and regulators can share responsibility without turning permissionless finance into a de facto banked system.

Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
