币界网报道：According to the news on June 24, Bitcoin Layer2 network Merlin Chain announced the official launch of the BTC staking function. Users can participate in the PoS mechanism through BTC, and the current annualized return can reach up to 21%. The first phase of the staking vault has been opened, with a capacity limit of 50 BTC. The reward settlement is expected to be carried out in early October 2025, and the capacity will be gradually expanded in the future depending on market demand. This update marks that Merlin Chain has officially entered the Bitcoin PoS stage. Users can participate in network security maintenance and income acquisition through BTC without off-chain operations. Merlin Chain founder Jeff said that in the future, he will continue to promote the standardization of the BTC staking mechanism, build a cross-chain BTC liquidity network, and provide BTC with composable and profitable infrastructure support. Earlier news, Merlin Chain's Layer2 mapping asset M-BTC has been deployed to more than 20 mainstream public chains such as Ethereum, Solana, Kaito, Sui, etc., with an active TVL of more than 4 billion US dollars. In terms of ecology, Merlin Chain cooperates with multiple BTCFi projects such as Babylon and Zerolend to promote the construction of scenarios such as staking, lending and re-staking, and provides early assistance to many long-term participants in the BTCFi track such as Solv Protocol and Avalon Labs.
