ChainCatcher news, AminoChain announced the completion of a $5 million seed round financing, led by a16z, marking a16z's first investment in a decentralized science (DeSci) project.It is reported that AminoChain is building an L2 blockchain protocol that connects enterprise healthcare institutions and developing user-owned decentralized healthcare applications on this protocol. The first application built on AminoChain is a biobank marketplace that allows researchers to query and license samples through a biobank network. Patients can track the usage of their samples, learn from new insights generated from the samples, and earn money when these samples are sold.

ChainCatcher message, the Hummingbird client of the Ethereum L2 blockchain LightLink has launched on the Celestia mainnet, publishing L2 data to Celestia DA and verifying it, sending only the block headers to Ethereum. LightLink states that using Celestia as its data availability layer will reduce costs compared to Ethereum, allowing us to save costs for end users in the form of lower transaction fees.

ChainCatcher message, in response to the statement "Coinbase Commerce no longer accepts payments using self-custodied Bitcoin wallets or other applications," Coinbase CEO Brian Armstrong stated on social media that Commerce is using a new EVM payment protocol, allowing users to pay from any self-custodied wallet. He believes that in the future, payments using cryptocurrency will mainly occur on L2 blockchains and hopes to help achieve this goal.Currently, the fastest checkout method on Commerce is using any ERC-20 on L2 blockchains (Base, Polygon, etc.), including Ethereum, USDC, wrapped Bitcoin, and thousands of ERC-20 tokens. As an alternative, if customers have a Coinbase account, they can pay using their Coinbase account, which includes direct payments with Bitcoin.Additionally, Coinbase is integrating the Lightning Network. They hope to have the opportunity to use the Lightning Network for commercial payments in the future. They believe that until we move away from Layer 1 and reduce transaction fees and confirmation times, using cryptocurrency for online payments will not truly become mainstream, so they are working to accelerate the journey towards this world.
