Merlin Chain launches BTC staking feature with annual yields up to 21%

Odaily Planet Daily reports that Bitcoin Layer2 network Merlin Chain has officially launched its BTC staking feature, allowing users to participate in the PoS mechanism with BTC, with current annualized returns reaching up to 21%. The first phase of the staking vault is now open, with a capacity limit of 50 BTC. Reward settlement is expected to take place in early October 2025, and the capacity will be gradually expanded based on market demand.
This update marks Merlin Chain's official entry into the Bitcoin PoS phase, enabling users to participate in network security and earn rewards with BTC without off-chain operations. Merlin Chain founder Jeff stated that the team will continue to promote the standardization of the BTC staking mechanism in the future, build a cross-chain BTC liquidity network, and provide composable and yield-generating infrastructure support for BTC.
Previously, Merlin Chain's Layer2 mapped asset M-BTC was deployed on more than 20 major blockchains, including Ethereum, Solana, Kaito, and Sui, with active TVL exceeding $4 billion. On the ecosystem front, Merlin Chain has partnered with several BTCFi projects such as Babylon and Zerolend to advance scenarios like staking, lending, and restaking, and has provided early support to long-term BTCFi participants including Solv Protocol and Avalon Labs.
