bitbank has launched an Ethereum staking service offering an estimated annual yield of 1.78%. Customers can participate by holding ETH in a bitbank account, agreeing to the service terms and enabling reward receipt settings. Rewards are distributed every Monday at about 11 p.m. UTC, or 8 a.m. Japan time, and there is no separate lockup period. The service gives Japanese users a regulated domestic exchange option for generating potential yield without using decentralized protocols or overseas platforms, although returns can vary with network conditions and validator performance. Opening a bitbank account is required, and users should review the service terms, including applicable account-opening and annual fees, before participating.
