ChainCatcher news, according to official sources, Manta Pacific has successfully integrated with the modular blockchain Nubit DA testnet. Through this integration, Nubit can enhance Manta's scalability, reduce costs, and elevate the security of the Manta network to a higher level.This enables dApps on Manta to leverage Nubit’s trustless, scalable data availability layer (protected by Digital Gold (Bitcoin)) as well as the existing infrastructure.

ChainCatcher news, Nuffle Labs, an independent entity established by the NEAR Foundation, has completed a $13 million strategic financing round. The funding comes from strategic grants from the NEAR Foundation and investments led by Electric Capital, with participation from Canonical Crypto, Fabric Ventures, Robot Ventures, Caladan, Lyrik Ventures, and others.Nuffle Labs is building the NEAR Data Availability Layer (NEAR DA), the NEAR Fast Finality Layer (NFFL), and other products within the NEAR modular product suite.The company stated in a press release: "As an independent entity, Nuffle Labs will now be able to make agile decisions to ensure that NEAR Modular products remain competitive. Nuffle Labs' strategic positioning between the NEAR Foundation, Ethereum, and the EigenLayer ecosystem will leverage the strengths of multiple platforms to enhance the efficiency and resilience of the NEAR ecosystem."

ChainCatcher news, Bitcoin data availability layer project Nubit has completed a $8 million seed round financing, led by Polychain Capital, with participation from Nomad Capital, Spartan Group, L2IV, Big Brain Holdings, GCR, Protagonist, Gate Ventures, Animoca, Mask Network, and others. The latest round of financing brings Nubit's total funding to $12 million. Nubit aims to develop the most secure and scalable data availability (DA) layer for multi-chain ecosystems, supporting limitless applications including AI, SocialFi, and GameFi. The team will launch the Alpha testnet in June, marking the final phase before the mainnet launch later this year.Additionally, the Web3 asset data platform RootData shows that Nubit is a scalable Bitcoin-native data availability layer, protected by Bitcoin. Nubit is capable of expanding Bitcoin's data capacity without compromise, empowering applications such as Ordinals, Layer 2s, price oracles, and indexers, thereby broadening the scope and efficiency of the Bitcoin ecosystem.

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 news, the zero-knowledge proof public chain Mina Protocol announced a partnership with the modular blockchain project Celestia. The Mina ecosystem will integrate Celestia's modular decentralized data availability (DA) solution.It is reported that the integration project is led by the zk-SNARKs pioneer team Geometry Research, with technical support from o1Labs.In addition, by introducing Celestia's DA solution, Mina's zkApps will gain significant capability enhancements, especially in handling large-scale off-chain data, where the throughput of zkApps will see further improvements. This collaboration coincides with Mina's upcoming mainnet upgrade, which will bring a more user-friendly zkApp programming model, expected to significantly increase developer activity and the number of products in the Mina ecosystem.

ChainCatcher news, Bitcoin native data availability layer Nubit has completed its angel round financing, with Bounce Finance and domo participating, but the amount raised has not been disclosed.According to RootData, Nubit is a Bitcoin native data availability layer designed to change the way transactions are processed on the Bitcoin network. Its development team Riema has proposed BRC-1310, a specialized Bitcoin native data availability standard that includes Bitcoin native staking, data availability sampling technology, direct data proof on the Bitcoin network, and decentralized bridges.

ChainCatcher news, the NEAR Foundation announced that its NEAR Data Availability layer (NEAR DA) is now available for Arbitrum Orbit, a tech stack that allows developers to launch their own configurable lightweight chains based on Arbitrum's technology. Arbitrum Orbit is a platform that provides L2/L3 scaling solutions for Ethereum, enabling developers to build dedicated chains with their own configurations. By integrating NEAR DA, lightweight chain builders can benefit from lower data availability costs, significantly reducing the overall overhead of lightweight chains.

ChainCatcher news, according to The Block, Celestia has integrated its data availability layer with Polygon Labs CDK. This integration introduces a dedicated data availability solution for Layer2 projects using Polygon CDK (such as OKX, Immutable, Astar, IDEX, Palm, and others) to reduce their gas fees.

ChainCatcher news, the Cosmos ecosystem DEX Osmosis has integrated the Celestia data availability layer. Osmosis stated that future Rollup networks can access liquidity anywhere and use any tokens on the Osmosis network for cross-chain payment of DA fees on Celestia. Osmosis also mentioned that it will soon integrate with the cross-chain application building platform Hyperlane.
