Arbitrum Orbit platform has added support for custom Gas tokens. These tokens are used to pay transaction fees. This development allows the Orbit blockchain to use specific ERC-20 tokens that comply with technical standards to process Gas or transaction fees on its network. Previously, the Orbit chain could only use Ethereum as a Gas token.

Arbitrum announced on X platform that after several months of development, Arbitrum Orbit is ready for mainnet deployment. Orbit uses Rust, C, and C++ to write smart contracts while maintaining full EVM compatibility of the Orbit chain. Using the efficiency of WASM, it saves over 10 times the gas cost in complex cryptography. Developers can customize the Orbit chain without DAO approval and without permission to adopt any improvements made to the Arbitrum Nitro technology stack, including license-free verification, MEV capture, and further cost reduction features.

The Celestia Foundation announced that Celestia will be the first modular data availability (DA) network to be integrated into the Arbitrum Orbit and the entire Nitro stack.

According to an official announcement, Celestia has announced its integration with Arbitrum Orbit as the first modular data availability network. This integration provides developers with the option to publish data to Abritrum One, Abritrum Nova, and Celestia. Arbitrum Orbit allows developers to create their own dedicated Orbit chain, which is compatible with one of Arbitrum's layer 2 (L2) chains: Arbitrum One, Arbitrum Nova, Arbitrum Goerli, or Arbitrum Sepolia, thus creating the most advanced scalable blockchain solution on the market.
