Multi-Party Computation Custody

Multi-party computation (MPC) custody is a security technology that splits private keys into multiple shards held by different parties or devices. To sign a transaction, these shards must be combined or used in a collaborative process, but the full key is never reconstructed in one place.

This provides the security of multi-signature wallets while offering greater flexibility and efficiency. MPC is increasingly used by institutional custodians to manage large portfolios of digital assets, as it allows for granular access control and policy enforcement.

It also mitigates the risk of single-point-of-failure attacks, as compromising one shard is insufficient to access the funds. MPC is a significant advancement in custody technology, enabling safer and more scalable management of digital assets.
