Built by experts who’ve made digital assets safer, and now, recoverable.
We believe asset recoverability is table stakes for the next era of digital assets.
From JP Morgan and Morgan Stanley to Coincover, Komainu, and beyond, the Circuit team understands deeply that real-world adoption of digital assets won’t happen until all digital assets are inherently recoverable.
Circuit didn’t begin as a recovery solution.
Initially, Harry set out to build a DeFi operating system, a flexible infrastructure layer for institutions navigating the digital asset ecosystem. But as he spoke with insurers, institutional traders, fund managers, crypto-native teams, and market makers, one issue kept surfacing: asset loss.
Through dozens of conversations, it became clear that the industry had normalized an unacceptable risk: if keys, people, or infrastructure failed, assets were stuck, or worse, completely gone. The core of crypto was built on this fragile assumption, and no one had truly solved it yet.
That realization changed everything.
Harry shifted focus to address the root of the problem: the lack of a dependable recovery mechanism for institutional-scale operations. Instead of securing private keys, the traditional but fallible approach, Circuit pioneered a new model: transaction-based recovery.
The idea was simple but transformative. Rather than storing keys, Circuit safeguards pre-signed transactions that can execute immediately in the event of failure. This eliminates single points of failure, prevents downtime, and ensures continuity even in worst-case scenarios.
By bringing the guardrails and resilience of traditional financial systems to digital assets, Circuit is redefining what security means in a 24/7 market, making permanent loss a thing of the past.
