🗝️MPC Account

Multi-party computation (MPC) is a cryptographic tool that allows multiple parties to make calculations using their combined data, without revealing their individual input.

In contrast to a standard SOA wallet account, you do not need to keep complex private keys with an MPC Wallet account, so an MPC Wallet account is also known as a Keyless wallet account.

User who joins UXLINK will receive an MPC wallet account, which will serve as their primary account for using UXLINK.
