Fireblocks is built for custody, not execution. Using MPC for AI agent trading is like bringing a vault to a drag race.
Even with MPC-CMP upgrades, network physics remains the bottleneck.
MPC requires multiple parties (key shares) to communicate over the network to generate a signature. Even with MPC-CMP reducing rounds from 9 to 1, the network latency between shares is irreducible physics. Packet drop = retry = 1000ms+ spike.
Network latency is inherently jittery. A strategy profitable at 50ms may be unprofitable at 700ms. This is the definition of non-deterministic execution.
Fireblocks optimizes for storage security, not execution speed. Their product is designed for institutional custody, where the key never moves. AI agents require the opposite: keys must execute instantly.
If you hold client funds that require multi-person governance (e.g. 5-of-7 humans must approve), Fireblocks is the gold standard.
It is an excellent Vault. It is a terrible Gun. Use Fireblocks for cold storage. Use ZeroCopy for the active trading hot wallet.
Cold storage. Multi-party governance. Human-speed approvals.
Use for 90-95% of AUM.
Hot execution. AI-speed signing. Autonomous agents.
Use for the 5-10% that trades.
Don't choose. Use both.
Keys are generated and stored inside a hardware-isolated enclave. RAM is never exported. No network attack surface.
Signing happens in-memory. No API calls. No REST overhead. Pure local execution.
XDP + AF_XDP eliminate syscall overhead. Profile-Guided Optimization (PGO) ensures the binary is tuned for your specific hardware. This is how we achieve 42µs.
Standard in the Validator Edition. A physical hardware-isolated kill switch to instantly revoke all signing authority without relying on the network.
If you're trading $10 billion in notional volume annually, and Fireblocks' latency causes you to miss just 5% of profitable trades, the cost is:
Fireblocks charges ~$18K/year for small setups, scaling to six figures for enterprise.
You're paying for the privilege of being slow.
Fireblocks is the right tool for custody. ZeroCopy is the right tool for execution.
If you need both, use both. But don't confuse them.
Our enclave signs transactions continuously. Every proof is cryptographically attested and publicly verifiable in real time.
