The restaking protocol's data availability service is live and attracting some usage, but most established layer-2 networks are sticking with Ethereum mainnet or Celestia instead.
<p>EigenDA, the data availability service built by restaking protocol EigenLayer, has struggled to win significant adoption from Ethereum's established rollups since going live, with most layer-2 networks continuing to rely on Ethereum mainnet or rival provider Celestia instead.</p>
<p>Data availability services solve a specific problem for rollups: transaction data needs to be published somewhere accessible so that anyone can verify a rollup's state and detect fraud, but publishing that data directly on Ethereum's mainnet is expensive at scale. Dedicated data availability layers like EigenDA and Celestia offer rollups a cheaper alternative, letting them publish transaction data off Ethereum's base layer while still maintaining a credible security model, at the cost of relying on a separate network's own security guarantees rather than Ethereum's directly.</p>
<p>EigenDA's pitch rests on EigenLayer's restaking model, where users who have already staked ETH can additionally secure EigenDA and earn extra yield for doing so, in theory linking EigenDA's security back to Ethereum's own economic security rather than requiring an entirely separate token and validator set the way Celestia does. That design has attracted interest from parts of the Ethereum community keen to keep more of the rollup stack economically tied to ETH itself.</p>
<p>In practice, however, adoption has lagged. Celestia launched earlier and built a head start with rollup teams and tooling specifically designed around its data availability model, giving it an entrenched position among newer rollups built from the ground up with a modular, non-Ethereum-native data layer in mind. Meanwhile, many of the largest and most established rollups -- including the networks that now dominate layer-2 DeFi activity -- have simply continued using Ethereum mainnet directly for data availability, prioritizing Ethereum's own security guarantees over the cost savings a dedicated DA layer offers.</p>
<p>That leaves EigenDA in an awkward middle position: distinct enough from Ethereum mainnet to offer real cost advantages, but not differentiated enough from Celestia, or established enough among the biggest rollups, to have carved out a clearly winning niche of its own so far. Restaking more broadly has also faced growing scrutiny over the added slashing risk it introduces for ETH stakers who opt into securing additional protocols like EigenDA, a tradeoff some validators have been cautious about taking on without clearer track records of the additional services they are securing.</p>
<p>Whether EigenDA closes the gap with Celestia -- or whether the broader push toward dedicated data availability layers loses ground to rollups simply staying on Ethereum mainnet as base-layer costs continue to fall -- remains one of the more unsettled questions in Ethereum's modular scaling roadmap heading into the rest of 2026.</p>
