The Uprising Verse will be the first Verse L2 launched using this innovative approach.

ChainCatcher news, the oracle API3 stated on X that the development of OEV Network has undergone a strategic shift, now based on Arbitrum Orbit. This is because Arbitrum Orbit has outstanding performance in terms of speed, operational costs, and scalability.

ChainCatcher news, the game L3 project Sanko GameCorp announced the mainnet launch on platform X. Users can bridge DMT from Arbitrum to Sanko through the native Sanko bridge, and any ERC-20 token on Arbitrum can be bridged to Sanko.Note: Please explore the native applications on the official website, SankoTools, Camelot, and SudoSwap are now live.Last September, Web3 infrastructure provider Caldera announced the launch of its first Arbitrum Orbit chain, with three partners planning to launch production-grade mainnet Orbit chains through Caldera in the coming weeks: Syndr, Sanko GameCorp, and Volatilis Technology.Syndr is a decentralized derivatives exchange with cross-margining, Sanko GameCorp is an online gaming studio, and Volatilis Technology will build a dedicated environment for DeFi to develop open currency markets.

ChainCatcher news, according to CoinDesk, DODO announced the launch of the Layer3 solution DODOchain. DODOchain is an "Omni Trade Layer3" supported by Arbitrum Orbit, EigenLayer, and AltLayer, focusing on integrating liquidity from different chains. DODOchain will utilize Ethereum's consensus and security features through EigenDA.In addition, DODOchain will also serve as a re-staking rollup, becoming one of the first Active Validation Services (AVS) in the Eigenlayer ecosystem. Currently, the DODOchain testnet is live.

ChainCatcher news, the multi-chain NFT game ecosystem Polychain Monsters launches an L3 game-specific chain based on Arbitrum Orbit through Altlayer, utilizing PMON for transactions, with support from Altlayer from the initial gameplay on the testnet to the mainnet launch.

ChainCatcher news, the blockchain gaming startup Proof of Play officially introduced its latest technological achievement------a multi-chain system built on the Arbitrum Orbit technology stack, combined with the company's exclusively developed on-chain game engine, which will initially launch the first batch of on-chain games on the Orbit technology stack.It is reported that this multi-chain system aims to provide optimized support for real-time fully on-chain gameplay and decentralized applications that can scale to internet levels. Furthermore, in the coming days, after the migration of "Pirate Nation" to the multi-chain system, it will become the first fully on-chain game running on its exclusive mainnet.

ChainCatcher message, ApeCoin DAO will develop ApeChain using the Arbitrum technology stack, building ApeChain as an Arbitrum Orbit chain developed with AnyTrust technology, and using APE as the gas and governance token for ApeChain. The ApeCoin community will have the option to implement upcoming features such as Stylus and BoLD.

ChainCatcher news, according to The Block, the Arbitrum Orbit platform has added support for custom Gas tokens. These tokens are used to pay transaction fees.It is reported that this development allows the Orbit blockchain to use specific ERC-20 tokens that meet technical standards to handle Gas or transaction fees on its network. Previously, the Orbit chain could only use Ethereum as the Gas token.

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, Arbitrum officials stated that after months of development, Arbitrum Orbit is ready for mainnet, and developers can now create custom blockchains using Arbitrum's infrastructure and tools without permission. Arbitrum Orbit uses Rust, C, and C++ to write smart contracts while maintaining full EVM compatibility for Orbit chains. By leveraging the efficiency of WASM, it saves over 10 times the Gas costs in complex cryptographic operations. In the future, Orbit chains can adopt any improvements made to the Arbitrum Nitro technology stack without DAO approval and without permission. This includes features such as permissionless validation, MEV capture, and further cost reductions.

ChainCatcher news, the modular blockchain Celestia has been integrated into the Arbitrum Orbit and Nitro stack, providing developers with the option to publish data to Arbitrum One, Arbitrum Nova, and Celestia. Developers will be able to use Celestia as a modular DA to deploy high-throughput Orbit chains.

ChainCatcher news, the Arbitrum development team Offchain Labs has released the Arbitrum Orbit development tools, aimed at helping developers more easily develop on the L3 blockchain Arbitrum Orbit and manage their own Arbitrum Rollup and AnyTrust chains.In addition, Offchain Labs also provides a quick start guide and Orbit DevNet on-chain tools, with plans to release testnet and mainnet guides in the future.

ChainCatcher news, Arbitrum announced the establishment of the Arbitrum Security Council, which is a 12-member multi-signature composed of community representatives, requiring 9 out of the 12 members to participate in emergency situations to take security emergency actions. The Arbitrum DAO will become the ultimate governance organization of the Arbitrum Security Council.In addition, Arbitrum also disclosed the L3 blockchain Arbitrum Orbit that developers can deploy directly. Developers launching L3 on Arbitrum One and Nova will automatically receive free and permanent licenses to use, modify, and customize Arbitrum technology for their L3 chains. The Arbitrum Orbit L3 chain will also support the upcoming Arbitrum Stylus, which will allow developers to use C, C++, and Rust programming languages for their chains, as well as Solidity and other EVM languages.
