ChainCatcher news, according to a post by SolanaFloor on the X platform, 21.co, a subsidiary of 21Shares, the world's largest cryptocurrency exchange-traded product (ETP) issuer, has launched the 21BTC native Bitcoin asset on Solana. This asset is 100% backed by BTC, with all reserves held 1:1 by a third-party custodian, and it has partnered with the well-known DEX Orca in the Solana ecosystem to achieve deep liquidity.

ChainCatcher news, according to sources, the Ethereum wallet MetaMask is integrating native Bitcoin (BTC). One insider stated that access could be realized within the next month, while another indicated that the exact features of Bitcoin have not yet been determined, but the functionality may initially be limited and expand over time.

ChainCatcher news, according to Chainwire, modular blockchain solution provider Avail has announced a partnership with dWallet Network to introduce native Bitcoin Rollup functionality within the Avail ecosystem. This collaboration will leverage dWallet's multi-party computation (MPC) infrastructure, allowing users to natively manage their BTC assets in any Rollup of the Avail ecosystem without relinquishing control over their digital assets.Under the terms of the partnership, Avail's Rollup smart contracts will be able to programmatically manage native BTC for the first time while retaining user ownership. This initiative represents a shift from traditional cross-chain solutions that may involve collusion risks (such as bridging technologies) to a non-colluding decentralized multi-chain layer solution. Avail co-founder Anurag Arjun stated that this collaboration not only enhances the programmability of BTC but also enables the implementation of Layer-2 chains or Rollups on top of the Bitcoin network.It is reported that this integration is achieved through Avail Nexus, which employs zero-knowledge collaborative Rollups, embedding light clients based on validity proofs and execution proof aggregation technology. This crucial step will help unify the Web3 ecosystem and enable developers to leverage Avail Fusion to borrow security from native assets of mature ecosystems like BTC and ETH.Additionally, the integration with dWallet Network will facilitate the implementation of the Fusion Security model, which, once launched, will allow users to securely hold BTC, ETH, or other assets and stake them through dWallets to enhance the security of the Avail ecosystem while maintaining ownership of their native assets. This will introduce the first native multi-chain staking/re-staking solution aimed at ensuring consensus security across different blockchains.

ChainCatcher news, OKX Ventures announced an investment in DLC.Link. DLC.Link is an innovative project aimed at bringing the power and innovation of DeFi into the Bitcoin ecosystem without compromising on security, decentralization, or user experience. DLC.Link collaborates with institutions (referred to as "dlcBTC merchants") to mint dlcBTC, a decentralized Bitcoin wrapper. Unlike other forms of wrapped Bitcoin, dlcBTC does not require Bitcoin to be entrusted to custodians or bridged to another blockchain.Dora, the founder of OKX Ventures, expressed excitement in supporting the vision and mission of DLC.Link. DLC.Link's dlcBTC solution brings revolutionary advancements for Bitcoin's application in decentralized finance (DeFi), with a non-custodial wrapping method that allows users to manage their Bitcoin independently, without worrying about third-party risks such as mismanagement or theft. Additionally, its unique token redemption cap mechanism and multi-account decentralized management strategy significantly reduce centralized risks and enhance system resilience. DLC.Link enables users to participate in the DeFi ecosystem through self-custody, fostering widespread user adoption and innovation, and opening the door to providing more value and choices for digital asset investors.
