CrypDefi is now Fortkey. read the announcement

    Securing assets in motion.

    Secure, client-controlled signing and policy enforcement for financial institutions.

    Why Fortkey exists

    We build the signing layer for everything that moves onchain.

    Institutional custody was designed to secure long-term holdings. Assets in motion need signing that is immediate, policy-checked and under the institution's own control.

    Fortkey provides it, alongside the custody infrastructure a firm already trusts. Keys stay in the client's own hardware-isolated enclaves, and every transaction is decoded, validated against policy and signed in under 1 ms.

    Proven in trading, where speed is the test.

    How we build

    Self-custody by construction

    Keys stay inside client-controlled, hardware-isolated environments. Fortkey never holds custody of client assets.

    Performance is measured

    We benchmark the signing path and design for predictable tail latency, not headline speed alone.

    Built for assets in motion

    Custody platforms secure assets at rest. Fortkey provides policy-controlled signing on the execution path, at trading speed.

    Trust should be evidenced, not implied.

    Security, performance and operational controls should be independently assessable, not asserted. The evidence we can share today, and the methodology behind it, is set out below.

    Security program

    ISO/IEC 27001:2022 certified, independently penetration-tested, with controls monitored through our Trust Center.

    Client-controlled architecture

    Signing material stays inside client-controlled, hardware-isolated environments. Fortkey never holds custody of client assets.

    Measured performance

    Cryptographic signing latency is reported separately from policy-checked end-to-end latency, with the methodology published. The full benchmark is published.

    Operational transparency

    Auditable event log, documented deployment options and a defined incident process, reviewable during due diligence.
