Fortkey constructs self-custody execution infrastructure designed specifically for institutional trading firms. The company offers a policy-controlled transaction signing and execution layer operating at sub-millisecond speeds through its HFT Vault. This architecture enables trading desks to execute manual or algorithmic trades across multiple DeFi chains without exposing plaintext private keys or taking on counterparty custody risks. The startup has demonstrated notable market validation by joining Tenity's European FinTech Accelerator Batch XV in late 2025.
