Nexus provides institutional-grade cross-chain security through distributed threshold cryptography. We eliminate the human element from bridge custody.
Distributed across 67 jurisdictions to ensure regulatory and physical resilience.
The industry's lowest Nakamoto Coefficient for cross-chain custody.
Completed by Trail of Bits, Spearbit, and Sigma Prime.
Actively securing assets for major DeFi protocols and L2 bridges.
Keys are never reconstructed. BLS signatures are generated through distributed fragments across hundreds of nodes using Secure Multi-Party Computation (SMPC).
Three layers of autonomous protection. Threat detection occurs locally and propagates network-wide without sharing sensitive data.
The network automatically pauses transactions that deviate from historical patterns, requiring multi-node consensus to resume.
In July 2023, the Multichain bridge collapsed following the arrest of its CEO. Because the signing keys were held in a centralized environment under single-entity control, $125M in user assets became unrecoverable.
CEO Detained: All administrative and cryptographic access is lost. No secondary key-shares exist.
Distributed Custody: Signing power is split across 847 independent nodes. No single arrest can freeze the protocol.
Nexus is closing a Series A funding round at a $15M post-money valuation. This capital is dedicated to expanding our distributed node network and formal verification of our SMPC implementation.
A detailed assessment of how different bridge architectures handle catastrophic failure scenarios. Trust minimization is the process of removing human or centralized intermediaries from the security equation.
| Security Vector | Legacy Multi-Sig | Centralized MPC | Nexus Protocol |
|---|---|---|---|
| Signing Authority | Small validator set (5-20) | Single entity/Admin servers | 847 distributed nodes |
| Key Management | Full keys held by individuals | Reconstructed in memory | Threshold secret sharing (DKG) |
| Failure Mode | Signature compromise/Collusion | Arrest/Admin server hack | Byzantine Fault Tolerance (40%) |
| Recovery Path | Manual rotation (Slow) | None (Hard coded) | Autonomous DAO Succession |
| Trust Profile | Trust in set of operators | Trust in single company | Trust in mathematics/MPC |
We are currently onboarding a select group of institutional partners. Request a security assessment to determine if your infrastructure is eligible for Nexus integration.
