Network upgrades on Mina can compel every zkApp to update its verification key, a demand that causes standard multisig setups to fail completely when trying to adapt. To resolve this challenge, Mina Multisig implemented an approach utilizing FROST. Before @nori_zk released this system on @MinaProtocol, Veridise conducted a thorough review of the solution, and this evaluation is currently documented on AuditHub. The software is now completely open source, making it an excellent resource for any Mina team working on wallet applications or self-custody tools.
