OpenSea Announces Arbitrum Nova Integration
OpenSea has now added Arbitrum Nova, allowing users to trade Nova NFTs on the multi-chain NFT marketplace. They’ve also joined the Data Availability Committee in order to further support Nova’s ecosystem.

The world’s biggest NFT marketplace, OpenSea, has announced that they have now integrated Arbitrum Nova onto their platform.
Users can now find various NFT collections from Arbitrum’s social and gaming-focused chain on the popular marketplace. You’ll now find them grouped up together with other Arbitrum collections using the “Arbitrum” chain filter.
Next to introducing the Ethereum-based Layer 2 network, OpenSea has also stated that they are “strengthening Nova’s ecosystem” by becoming a part of the Data Availability Committee (DAC), meaning that they’ll be able to bring access to on-chain data while helping to make sure the data provided is accurate. Other members of the DAC include Reddit, Consensys, Google Cloud and more.
Arbitrum Nova aims to offer a high level of security while featuring low transactions fees with quick transaction processing times. It’s optimized to handle large transaction volumes, making it designed to handle blockchain dApps, social projects and web3 games. The small transactions fees are achieved thanks to using a new security model where the DAC is at the core, as it receives data batches of compressed transactions from the sequencer and then provides a Data Availability Certificate, which the sequencer then puts on the Ethereum network. In the event that a certificate cannot be generated, the chain uses a fallback to Arbitrum Rollup and thus sends compressed calldata over to Ethereum.
This is now the 9th chain to be added to OpenSea, with the multi-chain marketplace introducing Arbitrum support back in September last year, followed by BNB Chain integration in November.
