Technical Features
MPC + HSM
Threshold MPC running as a signed Functionality Module inside the Thales Luna tamper boundary.
Secure TSS Protocol migration
Migrate from your existing MPC in an easy and cryptographically secure way
Signature Reveal
Prove which infrastructure produced a signature, when, under which policy, against which environment.
Node as a service
Production-grade MPC signing nodes operated by Silence Laboratories.
Hierarchical signatures
Verifiers see one identity; complex multi-party authorisation happens cryptographically off-chain.
Hardened derivation
BIP-32 hardened derivation under threshold MPC. Account-level isolation, xpub-safe back-office derivation, full standards compatibility
Identifiable abort
Identifying nodes which do not respond as per protocol rules
Dynamic Quorum
Add or remove signers without affecting your existing processes
Asynchronous key generation
All parties do not need to be online for key generation
Pre-Sign processing
Utilizing MPC network downtime to pre-process and speed up transactions
Recovering lost keys (w/o backup)
Recovering assets even when one of the signers loses their key and backup
Weighted threshold signatures
Different weights for each share as a function of staked amount
