About Fortkey

Fortkey is self-custody execution infrastructure for trading firms. We make the wallet that signs your on-chain trades: fast enough for algorithmic execution, controlled enough to hand to your auditor. Vaults deploy in your own environment, next to your trading code. Keys exist only inside hardware-isolated enclaves, every transaction is checked field by field against your policies before it is signed, and signing takes under a millisecond: p99 of 372 microseconds, benchmarked. Routing is MEV-protected through private order flow, co-located with leading builders and venues. Your custodian keeps the treasury. Fortkey runs the trading. One wallet covers every mode: HFT vaults for bots, an API for your services, and FortkeyLink for manual trading through MetaMask or any other browser extension, all on the same keys under the same policies. Nine chain families, including EVM, Solana, and Canton. We work with market makers, HFT firms, and active on-chain trading desks across Europe and globally. Flat infrastructure pricing, no volume fees. ISO/IEC 27001:2022 certified and independently penetration tested, with the evidence available in our Trust Center. Fortkey is the brand name of CrypDefi BV, formerly operating as CrypDefi. Same company, same product. Try the sandbox or talk to engineering: www.fortkey.io
