MPC Wallets for Modern Crypto Security
Our Platform & Wallet technology is fortified with MPC, delivering unparalleled security without compromising on flexibility.
Finrock – Middleware for Crypto, Blockchain & Web3
What is MPC?
Finrock uses a state-of-the-art security technique called Secure Multi-Party Computation (MPC), which eliminates the possession of a single private key, by having various shares (aka shards) generated by multiple parties, ensuring that no single entity has access to the complete key. Transactions are signed and broadcasted using a single signature, and the key shares of the signers remain private, providing an extra layer of security for your digital assets
Why MPC wallets?
Reduced single-point risk
Because wallet control is split across multiple shares, one compromised device or system is not enough to take over the wallet.
Institutional-grade controls
MPC wallets supports approval workflows, policy-based governance, and shared authorization for sensitive transactions.
Simplified recovery models
Our MPC wallet reduces reliance on traditional seed phrase management, helping improve onboarding and recovery experiences.
Scalable infrastructure
Suitable for consumer apps, custody platforms, embedded wallets, and enterprise treasury operations across multiple blockchain ecosystems.
MPC = Trustworthy
Trust in digital asset security comes from removing single points of failure and enforcing controls at the cryptographic level to help reduce exposure to theft, insider risk, and operational mistakes.
- No complete private key stored in one location
- Stronger protection against device compromise and credential theft
- Support for shared approvals and internal governance policies
- Improved business continuity and operational resilience
- Secure infrastructure for institutional and customer-facing wallet products
Distributed KeyGen (DKG)
Distributed Key Generation, or DKG, is the process used to create wallet key shares across multiple participants without ever generating the full private key in one place. Each party contributes to the key creation protocol and receives its own share, while the wallet’s public key is produced collectively.
This is one of the most important security foundations of an MPC wallet. Because the private key is never fully assembled during setup, DKG helps remove a critical weakness found in traditional key generation models.
Key refresh
Key refresh allows a wallet to rotate or renew key shares over time without changing the wallet’s public address. The shares are cryptographically refreshed so the wallet keeps the same identity on-chain while the underlying share material is updated.
- Adding a new participant (or a share)
- Removing an existing participant (or a share)
- Change of approver's threshold among existing participants.
- Rotation of shares across all existing participants.
HD Wallets
HD derivation refers to hierarchical deterministic key derivation, which allows many wallet addresses or child keys to be generated from a common root structure. Our MPC wallet adapts this features, so participating parties derive and manage child key shares without exposing the underlying master secret.
This makes it easy to backup a wallet with thousands of addresses with just one file per account organization. For platforms that need many user wallets or transaction paths, HD derivation brings structure and scalability to MPC-based infrastructure.
Distributed signing
Distributed signing is the process that allows multiple parties to jointly produce a valid blockchain signature using their individual key shares. Instead of reconstructing the private key before signing, each participant performs its part of the cryptographic operation and the final signature is produced through a coordinated protocol.
The result is a standard signature that can be verified on-chain, while the private key itself never appears in full. This is the core mechanism that enables our MPC wallets to combine real-world usability with advanced cryptographic protection.
MPC wallets vs traditional wallets
Traditional wallets often depend on one private key or one recovery phrase, which can become a single point of failure if lost, stolen, or exposed. MPC wallets replace that model with distributed control, helping improve resilience, governance, and security posture.
Common Use-cases
As digital asset adoption grows, security, usability, and governance need to work together. MPC wallets provide a modern foundation for protecting funds while supporting controlled approvals, scalable wallet creation, and flexible recovery experiences.
