Institutional Security
Without Seed Phrases
Multi-Party Computation (MPC) wallets eliminate the single point of failure in traditional crypto wallets. Private keys are never assembled in one place — instead, cryptographic key shares are distributed across multiple parties, requiring threshold consensus to sign transactions. We build enterprise MPC wallets for institutions, exchanges, and Web3 companies.
What Is MPC Wallet Technology?
The most significant advancement in crypto key security since hardware wallets — and far more practical for institutions.
Key Shares, Not Keys
Instead of one private key that controls all funds, MPC splits the key into multiple cryptographic shares distributed across different parties (devices, servers, or people). No single share can sign a transaction alone — threshold consensus is required.
Threshold Signatures (TSS)
Using Threshold Signature Schemes (TSS), a minimum number of key share holders (e.g., 2-of-3 or 3-of-5) must cooperate to sign a transaction. The private key is never assembled — signing happens through secure multi-party computation.
No Single Point of Failure
Even if an attacker compromises one key share holder, they cannot steal funds. Even if one share is lost, the wallet can still operate. This eliminates the catastrophic risk of seed phrase theft or loss that plagues traditional wallets.
MPC Wallet Development Services
Complete MPC wallet infrastructure for every use case.
Institutional Custody Wallet
Enterprise MPC custody solution for exchanges, funds, and financial institutions. Supports 2-of-3 to 5-of-7 threshold schemes, hot/warm/cold wallet tiers, automated policy enforcement, and regulatory reporting.
Consumer MPC Wallet
User-friendly MPC wallet where key shares are split between the user's device, your server, and an optional backup service. No seed phrase required — users recover access through email/phone verification.
Multi-Sig Alternative
MPC-based threshold signing as a superior alternative to on-chain multi-sig. Same security model but works on any chain (including non-native multi-sig chains like Bitcoin), with lower gas costs and privacy.
DeFi MPC Integration
MPC wallet with full DeFi connectivity — interact with any smart contract, DEX, or lending protocol while maintaining institutional-grade key security. Policy engine enforces transaction limits and whitelists.
Key Rotation & Recovery
Proactive key refresh protocols that periodically regenerate key shares without changing the public key or on-chain address. Eliminates the risk of share compromise over time. Includes disaster recovery procedures.
Compliance & Reporting
Built-in transaction monitoring, AML screening, travel rule compliance, and audit trail generation. SOC2 Type II ready infrastructure with role-based access control and approval workflows.

MPC Wallet FAQ
An MPC (Multi-Party Computation) wallet uses cryptographic techniques to split a private key into multiple shares distributed across different parties. Transactions require a minimum threshold of shares to cooperate — the private key is never assembled in one place, eliminating the single point of failure in traditional wallets.
Multi-sig requires multiple on-chain signatures, which is chain-specific, visible on-chain, and costs more gas. MPC achieves the same security model off-chain — it works on any blockchain, is invisible on-chain (looks like a single signature), and costs the same gas as a regular transaction.
Yes. In consumer MPC wallets, key shares are distributed between the user's device, your server, and an optional backup. If the user loses their device, they can recover using the server share plus identity verification (email, phone, biometrics). No seed phrase required.
We support any t-of-n threshold scheme — 2-of-3 (most common for consumer wallets), 3-of-5 (institutional), and custom schemes. We implement both GG20 and CGGMP21 protocols, which are the industry-standard MPC signing algorithms.
A basic consumer MPC wallet takes 12–16 weeks. An enterprise institutional custody platform with policy engine, compliance, and multi-tier architecture takes 6–12 months. Timeline depends on the threshold scheme, number of chains, and compliance requirements.
