MPC Wallet
An MPC wallet uses multi-party computation so signing authority is divided among multiple parties or devices without reconstructing one full private key in a single place.
✦ Key Insight
It can reduce single-key exposure and support institutional or consumer recovery designs.
✕ Common Misconceptions
MPC is not automatically decentralized or non-custodial; provider control and recovery design must be reviewed.
Detailed Explanation

Private Key
A private key is a secret cryptographic code that proves ownership of crypto assets and allows the holder to authorize transactions.
Multisig Wallet
A multisig (multi-signature) wallet is a smart-contract or script-based wallet that requires multiple independent signatures to authorize a transaction — for example, 2-of-3 or 3-of-5 — instead of a single private key.
Custody
Custody describes who controls the private keys required to access and move cryptocurrency. In a self-custody arrangement, the user controls their own private keys or secret recovery phrase. In a custodial arrangement, an exchange, platform, broker, bot provider, or another third party controls the keys on the user's behalf.
Threshold Signature Scheme (TSS)
A Threshold Signature Scheme lets a defined threshold of participants cooperate to create one valid digital signature.
