Casa has been helping customers secure their bitcoin in multisig wallets since 2017.Casa’s multi-key vaults are an easy-to-use version of multi-sig product, which also come with customer support.Before Casa, multi-sig software lacked customer support and was too complicated.Casa’s approach of being customer-friendly has paid off, as the company has become a household name in the Bitcoin and crypto space.The company offers two main set ups: 5-key vault and 3-key vault.Casa’s new Enterprise Plan is designed for companies to more easily secure their bitcoin treasuries.This summer, Casa began enabling users to replace hardware wallets used in their vaults with YubiKeys.In March, Casa launched Casa Inheritance, a service to access the bitcoin in the vaults in the event of the user’s death.Nick Neuman, the CEO of Casa, believes that more people will come around, and multisig will become more widely-adopted.For those that want to try Casa, the company is allowing people to try the service at no charge for a month.
