Custodial Staking is a technology infrastructure solution that enables businesses to participate in secure, efficient, and cost-effective crypto staking through a custodial model. This service is designed for institutional clients looking to scale their crypto assets staking capabilities without the complexities of managing private keys and technical setups. With a user-friendly and intuitive interface, the SIX Digital Asset Platform simplifies the staking process, allowing businesses to easily participate in staking and earn rewards. Staking allows users to participate in securing the network by locking up tokens. The rewards are distributed on chain, which means the process of earning these rewards is completely automatic. Every time a block is validated new tokens of that currency are minted and distributed as staking rewards. SIX SIS’s integration tools and experience operating in institutional markets give our clients easy access to crypto staking capabilities with high security and reliability standards.
