For most of the NFT boom, transaction fees on Ethereum were the single biggest pain point for casual users. Buying or minting a single piece could cost more than the artwork itself during peak periods, alienating creators who simply could not justify the overhead. The Dencun upgrade, which introduced proto-danksharding through EIP-4844, has changed the calculus dramatically.
The technical innovation behind Dencun was the addition of blob transactions, which allowed Layer 2 networks to publish data far more cheaply to the Ethereum mainnet. For end users, this translated into a sharp drop in costs on rollups such as Arbitrum, Optimism, Base, and zkSync. Many NFT marketplaces have since shifted significant volume to these networks, where gas fees are often a fraction of a cent.
The downstream effect has been a renewed wave of experimentation. Projects that were too gas-sensitive to launch on Ethereum mainnet, such as on-chain games or open editions with thousands of mints, have flourished on Layer 2. Free mint culture, which had been hampered by network congestion, also returned in force, particularly on Base and Zora.
For collectors, the trade-offs are nuanced. Mainnet Ethereum still hosts the most prestigious blue-chip collections, and many serious buyers continue to prefer settling there for liquidity and security reasons. Layer 2 ecosystems, however, are becoming the launchpad of choice for new collections looking to attract a wider audience without scaring users away with gas costs.
Looking forward, further upgrades aimed at reducing fees and increasing throughput are already on the Ethereum roadmap. The Dencun moment is significant not only for what it accomplished but for what it signaled: that the NFT ecosystem and Ethereum’s core development priorities are increasingly intertwined, and that scaling progress directly shapes the kinds of cultural experiments collectors get to participate in.
