Your custodian keeps the treasury. Fortkey runs the trading.
Custody platforms were built to secure assets at rest. Low-latency trading is a different job: policy-controlled signing authority on the execution path, microseconds from your venues. Fortkey wallets are purpose-built for that job. Move your trading float, keep your treasury exactly where it is, and retire the in-house signer you never wanted to maintain.
Latency never costs you a fill.
Pre-built HFT vaults co-located with your venues and builders. Decode, policy check, and signature in under a millisecond, MEV-protected routing, and a Rust SDK for the algorithmic flow.

Every transaction decoded and checked field by field inside the enclave, before the signature exists. Whitelists, velocity limits, simulator, approvals, and audit.

Trade anywhere. Keys stay home.
FortkeyLink presents your enclave wallets as a hardware wallet. Traders keep MetaMask, Phantom, or any other browser extension and trade any DEX, every order policy-checked.
