Crypto staking-as-a-service is a service that allows cryptocurrency holders to participate in the process of staking their coins without the need to manage the technical aspects themselves. Staking involves holding a certain amount of cryptocurrency in a wallet to support the network's operations and in return, earning rewards in the form of additional coins. Staking-as-a-service providers handle the technical requirements of staking, such as running the necessary software and maintaining network connectivity, while users delegate their holdings to the service provider for staking purposes. This model enables individuals to earn staking rewards without having to actively manage the process.
