the NEAR Foundation announced that its NEAR Data Availability Layer (NEAR DA) is now available on Arbitrum Orbit, a technology 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, allowing developers to build their own dedicated chains with their own configurations. By integrating NEAR DA, lightweight chain builders can benefit from lower data availability costs and significantly reduce the overall cost of the lightweight chain.
