MPCVault is built with security as a first principle. Our architecture eliminates single points of failure, enforces policy-driven controls, and ensures full operational transparency-without compromising speed or usability.
Multi-cloud
MPCVault secures assets with TEEs and encryption on AWS, Azure, and Google Cloud.
Periodic key refresh
Private key shares change periodically while your public address remains the same.
Hardened isolation
Patented technology ensures compromise on one chain never risks assets on another.
Transaction simulation
See exactly what will happen to your balance before you sign.
Parameter decoding
Human-readable parameter decoding lets teams verify transactions before signing.
Organization key export
Export private keys to retain full ownership and eliminate platform lock-in.
Patented MPC-based hardened derivation
MPCVault utilizes a strongly-isolated key derivation structure to provide a level of security that traditional non-hardened wallets cannot match
Unique derived keys isolate assets across blockchains, preventing signature reuse.
Hardened MPC keys protect the master key, even if a child key is compromised.
Granular access control
Hierarchical permissions restrict signing access without exposing root keys.
Industry-first MPC security
Patent MPC derivation enables hardened security with key rotation.
Enterprise scalability
Account-level key exports are supported without affecting vault-wide security.
Key shares distributed across independent cloud environments
Signing authority is split into rotating MPC key shares across multiple clouds.
Zero-trust architecture with peer-to-peer encrypted node communication.
Trustless relays ensure message privacy across multi-cloud environments.
Firewall-protected nodes prevent unauthorized access and execution.
Optional external key share recovery reduces counterparty risk.
Keys that evolve over time—without changing your address
Continuous key rotation
Long-lived keys are a liability. MPCVault's MPC algorithm supports periodic key refresh, where key shares are updated to new values over time while the public key remains the same.
No single-party exposure
The refresh occurs without any single party learning the full key, and after a refresh, any less-than-quorum subset of shares becomes meaningless, reducing the risk of "slow" or adaptive compromise over time.
Cryptographic continuity
The mathematical framework of the system ensures that the sum of the refreshed shares always equals the original whole private key, maintaining seamless continuity for the user.
Predictable approvals with pre-sign execution visibility
Pre-sign visibility
Simulate transactions to preview outcomes before any signature is produced.
Clear impact preview
Instantly see balance changes and state updates from complex smart contract calls.
Malicious logic detection
Expose harmful or deceptive contract behavior by simulating against current chain state.
Reviewer-ready results
Provide parsed and raw simulation outputs for UI review and automated risk checks.
Readable intent, not bytes
Decode raw call data into clear methods, names, and structured arguments.
Verify exact method calls
Ensure the transaction calls the intended function—not a hidden or malicious one.
Full parameter transparency
Review every address, value, and parameter in a clear, structured format.
Full ownership,
no lock-in
Export encrypted key shares to maintain independent custody and recover funds outside MPCVault when required.
Root-key based recovery
Key derivation ensures exported root keys can recover both existing and future wallet addresses.
Zero visibility
exports
Key shares are encrypted using your public keys—MPCVault never sees usable secrets or decrypted data.
Approval-gated & secure
All active members must approve exports, with backup packages designed for secure, redundant storage.
