CrypDefi is now Fortkey. read the announcement

    We build the execution layer for institutional trading.

    Secure, client-controlled signing and policy enforcement for latency-sensitive markets.

    Why Fortkey exists

    Institutional trading needs secure signing authority where orders execute.

    Institutional custody was designed to secure long-term holdings. Latency-sensitive trading requires signing authority that is immediate, policy-controlled and available where orders execute.

    Fortkey provides that execution layer alongside the custody infrastructure a firm already trusts. Keys remain client-controlled, and every transaction is decoded, checked and signed before it reaches the market.

    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 p50, p95 and p99 latency, not headline speed alone.

    Purpose-built for trading

    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. Full p50/p95/p99 benchmarks soon.

    Operational transparency

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