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.
See the security architecturePerformance is measured
We benchmark the signing path and design for predictable tail latency, not headline speed alone.

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