OpenSea Adds Support for Abstract Blockchain

OpenSea has added the Abstract blockchain to its list of supported networks, enabling users to trade NFTs and tokens built on the Layer 2 chain.

With the addition, Abstract-based NFT collections are now available on the marketplace. Abstract is a Layer 2 network built on Ethereum and developed by Igloo Inc., the company behind the Pudgy Penguins NFT collection.

This brings the total number of blockchains supported by OpenSea to 19, as part of its broader effort to offer multi-chain access to NFT creators and collectors.

What is Abstract?

Abstract is a Layer 2 blockchain built on Ethereum that uses zero-knowledge rollup (ZK-rollup) technology.

This approach allows the network to handle transactions off-chain while still benefiting from Ethereum’s security by confirming transaction validity through cryptographic proofs.

Developed by Igloo Inc.—also known for the Pudgy Penguins and Lil Pudgy NFT collections—Abstract is designed to support scalable, consumer-focused blockchain applications. It aims to offer low-cost, high-speed infrastructure for NFT projects.

Why is this significant?

OpenSea remains one of the most active NFT marketplaces by user count and trading volume. Adding Abstract to its list of supported chains allows the network’s projects to become accessible to a wider audience.

The move also aligns OpenSea with broader developments in the NFT space, where many new projects are choosing to launch on Layer 2 networks due to their lower fees and faster confirmation times.

For Abstract, this listing helps validate its infrastructure and improve its visibility among traders who primarily operate through OpenSea.
