An MPC wallet (Multi-Party Computation wallet) is a crypto wallet that splits your private key into multiple encrypted parts, making it safer than single-key or multisig wallets while keeping you in full control.
MPC wallets divide a private key into encrypted shares stored across different devices or servers. This prevents single points of failure, enhances privacy, and ensures that only you can authorize transactions. Compared with multisig, custodial, and hardware wallets, MPC wallets offer a balanced mix of security, usability, and flexibility.
An MPC wallet is a next-generation crypto wallet built on Multi-Party Computation, a branch of cryptography. Instead of storing a single private key, the wallet creates multiple encrypted key shares. Each share is stored in different locations, such as your device and a secure provider. When you approve a transaction, these shares collaborate to sign it, but the complete key never exists in one place.
This approach removes the single point of failure inherent in traditional wallets. If a hacker were to compromise one share, it would still be useless without the other. For the user, the experience feels similar to using a standard crypto wallet, but the protection level is significantly higher.
The logic behind MPC wallets is simple: no single entity ever has full control of the key. For example, one share might remain on your smartphone, while another is kept on a secure server. When you send funds, the two shares communicate briefly to authorize the transaction.
A useful analogy is a safe that requires two halves of a code to open. One half is in your pocket, and the other is in a bank vault. Only when both are used together does the safe open, yet neither half is meaningful on its own. This distributed model significantly raises the security bar without making the wallet harder to use.
Under the hood, MPC wallets rely on advanced cryptography. The most common methods include Distributed Key Generation (DKG) and Threshold Signatures. With DKG, no single party ever generates the full private key. Instead, each party creates and holds only their share from the beginning. Threshold signatures allow transactions to be approved if a required subset of key shares participate (e.g., 2 out of 3), making the system fault-tolerant.
Some MPC implementations also use zero-knowledge proofs, which allow one party to prove they know a secret (like their share of the key) without revealing it. These techniques ensure both security and privacy while keeping the user experience seamless.
Different wallet models exist in crypto, each with strengths and weaknesses. The table below compares MPC wallets with multisig, custodial, and hardware wallets.
The main advantage of MPC wallets is that they remove the single point of failure present in traditional wallets. They also offer privacy because no additional signatures appear on-chain, and flexibility because user access policies can be updated without complex technical changes.
However, MPC wallets are not perfect. They rely on sophisticated cryptographic systems, meaning you must trust the provider’s technology. If a provider’s infrastructure experiences downtime, it can temporarily block transactions. Users also remain responsible for securing their password and device.
In summary:
MPC wallets are considered one of the safest options for managing cryptocurrencies. By splitting a private key into shares, they eliminate the single point of failure that makes traditional wallets vulnerable. This means that even if one share is hacked or stolen, it is useless without the other.
That said, no system is entirely risk-free. Safety depends on choosing a reputable provider, maintaining device security, and protecting your password. Risks include potential downtime if a provider’s servers are offline, as well as phishing attacks targeting users. Still, for most active users and institutions, MPC wallets provide stronger protection than multisig or custodial solutions.
Setting up an MPC wallet is quick and straightforward. With Bleap, you can get started in just 30 seconds:
That’s it, your wallet is ready! The experience feels almost identical to using a traditional wallet, but under the hood, it’s protected with MPC technology. This means your keys are split into secure shares, giving you institutional-grade security without added complexity.
MPC wallets are popular across the crypto industry. Institutions such as custodians, funds, and exchanges rely on them to protect billions in assets. DAO treasuries and DeFi protocols implement them to safeguard shared funds with transparent governance. More recently, consumer apps have started integrating MPC to deliver institutional-grade security in an everyday wallet experience.
At Bleap, MPC technology is the backbone of wallet security. When you create an account, PortalHQ generates a unique MPC key. One part of this key is stored on your device, while the other remains on PortalHQ’s infrastructure. Every time you sign a transaction, the shares work together briefly, but the full key is never exposed or stored in one place.
Passwords add another layer of protection. Your password is randomly generated and never stored by Bleap. Instead, it encrypts your key and stays only on your device, email, or cloud backup. Even if an attacker gained access to the encrypted key, it would be useless without your password.
This design ensures Bleap remains fully non-custodial. Neither Bleap nor PortalHQ can move your funds or restore them without your password. The result is a wallet that is always under your control.
What is an MPC wallet in crypto?
It’s a wallet that divides a private key into multiple encrypted shares, making it safer than single-key wallets.
MPC wallets provide shared control without leaving visible on-chain signatures, offering better privacy and flexibility.
Yes. Only the user can authorize transactions, even though one share is stored externally.
A wallet that doesn’t use a traditional private key but instead relies on distributed cryptography and user credentials.
Multisig wallets record all signatures on-chain and are harder to update when signers change.
MPC wallets are among the safest for active users and institutions, while hardware wallets remain the best for long-term cold storage.
MPC wallets are one of the most advanced ways to secure cryptocurrency today. By splitting private keys into multiple encrypted shares, they eliminate single points of failure, protect privacy, and maintain user control. Compared to multisig, custodial, and hardware wallets, they offer an exceptional balance of safety and usability.
For individuals who want institutional-grade protection in a simple mobile app, Bleap’s MPC wallet combines security with convenience—ensuring your funds are always safe, accessible, and under your control.
