[Xverse Launches Bitcoin Self-Custody Staking Service, Assets Remain on Bitcoin Mainnet Throughout] According to CryptoBriefing, Bitcoin wallet Xverse has launched a joint Bitcoin staking service. Users can pair sBTC with STX tokens to participate in Stacks PoX-5 lock-up cycles. During the staking period, Bitcoin remains entirely on the Bitcoin mainnet and under the user's control, without the need for cross-chain operations or wrapping. This feature requires upgrading to the Xverse v2.9 wallet version. Registration will close on September 9 or when the quota is fully subscribed. Staking rewards are expected to be distributed starting September 10 (Bitcoin block 966350, corresponding to Stacks cycle 143). Institutions such as UTXO (a subsidiary of Nakamoto Inc.), HashKey Cloud, and 21shares have joined as anchor participants. Previously, Xverse managed approximately 152 million STX in non-custodial staking.
