Execution infrastructure
Add low-latency signing to Fireblocks
Keep Fireblocks for custody and add CrypDefi as the execution layer for the on-chain hot path. You get sub-1ms signing, MEV-protected routing, and self-custody by default, all composing with your existing Fireblocks setup. Nothing to rip out and replace.
Positioning
Custody at rest vs authority in motion
Fireblocks and other custodians secure your assets at rest. Latency-sensitive on-chain trading has a different constraint: signing authority on the execution path, where milliseconds move P&L. CrypDefi is control infrastructure for that hot path. It sits on top of your custody and trading stack instead of replacing it.
Capabilities
What CrypDefi adds on top of Fireblocks
Sub-1ms signing
Multi-region, co-located with leading block builders.
MEV protection
Transactions broadcast through private order flow rather than the public mempool.
Self-custody by default
Keys never leave the enclave, and CrypDefi never holds your signing material.
On-prem deployment
The enclave runs inside your own environment, and the hot path is a local RPC call with no remote round-trip.
Payload-aware policy
Compiled inline into the signing runtime, so control doesn't cost latency.
Flat infrastructure pricing
Tied to sites, signers, throughput, and integrations. No volume fees.
Chain-agnostic
40+ live blockchain integrations and counting.
ISO/IEC 27001:2022 certified
Independently audited information security management.
Composition
How it fits
CrypDefi composes with incumbent custody and settlement, so you keep Fireblocks, Fordefi, Copper, Ledger, or BitGo. There is no migration. You add CrypDefi's execution layer alongside what you already run.
FAQ
Frequently asked
Does CrypDefi replace Fireblocks?
No. CrypDefi isn't a custody replacement. It's a neutral execution layer that composes on top of Fireblocks and your existing trading stack.
How fast is signing?
Sub-1ms. Signing and policy run inline in the hot path, inside an enclave co-located with block builders.
Is it self-custody?
Yes. Keys never leave the enclave, which runs inside your own environment, and CrypDefi never holds your signing material.
How is it deployed?
On-prem by default, into your own data center, cloud account, or colo. A CrypDefi-hosted sandbox is available so you can evaluate it first.
What does it cost?
Flat infrastructure pricing with no volume-based fees.
