Yes, approximately 70 percent of the circulating supply of cryptocurrencies is locked up in three main lockers: Convex, Michael, and Stake DAO. These lockers are designed to help protect the value and security of digital assets. They provide secure storage for digital assets and also enable users to securely transfer and trade their assets. Convex and Michael are both custodial lockers, meaning they provide secure storage for digital assets and offer a variety of services such as account creation, asset management, and asset transfer. Stake DAO is a decentralized locker, meaning it is managed and controlled by a decentralized network of users. All three lockers provide users with a secure and reliable way to store and manage their digital assets.
