The competition between Ethereum Layer 2 networks has become one of the defining storylines of the current NFT cycle. Where mainnet Ethereum once dominated nearly all serious NFT trading, today the landscape is increasingly split among Base, Arbitrum, Optimism, and zkSync, each pursuing slightly different strategies for attracting creators and collectors.
Base, incubated by Coinbase, has been particularly aggressive in courting consumer-friendly NFT projects. Its low fees and seamless onboarding through Coinbase Wallet have made it a natural destination for free mints, social experiments, and projects targeting first-time NFT users. Zora, a marketplace deeply integrated with Base, has popularized a model where almost any creative output, from photography to short videos, can be tokenized cheaply.
Arbitrum has taken a different angle, leaning into gaming and high-volume trading. Studios building on-chain games or marketplaces with frequent transactions have gravitated to its ecosystem, drawn by its early developer tooling and growing liquidity. Long-running projects such as Treasure DAO have helped cement Arbitrum’s reputation as a hub for play-and-earn experiments.
For collectors and creators, the proliferation of L2s introduces both opportunity and friction. Multi-chain identity has become a real concern, since wallets and reputations no longer live in a single place. Bridges, although faster and cheaper than they were, still introduce risk and confusion for newer users. Marketplaces have responded with cross-chain interfaces that abstract some of that complexity away.
The longer-term outcome of this competition is unlikely to be one winner. Instead, the most plausible scenario is a layered ecosystem where Ethereum mainnet remains the prestige settlement layer, while different L2s specialize in particular kinds of NFT activity. The “wars” framing is dramatic, but the practical reality looks more like a federation of complementary networks, each shaping the NFT experience in its own way.
