EigenDA

EigenDA is a secure, high-throughput, decentralized data availability (DA) service built on top of Ethereum using EigenLayer restaking primitives. Developed by Eigen Labs and operated as the flagship product of EigenCloud, EigenDA accepts blobs of rollup data from rollup sequencers, erasure-codes them, distributes the chunks across a network of EigenLayer-restaked operators, and produces aggregate BLS signatures that anchor data availability on Ethereum L1. The service is positioned as a hyperscale DA layer for rollups, advertising 1 GB/s of design throughput and is secured by 4M+ ETH restaked through EigenLayer with validators that include Coinbase, Google, Nethermind, and Puffer. EigenDA is consumed today by rollups and chains including Celo, MegaETH, and Aevo, with integrations available for Arbitrum Orbit, OP Stack, Nitro, and the Sovereign SDK. The protocol exposes a gRPC API surface across a Disperser (blob ingest and status), Relays (blob and chunk retrieval), Retriever (reconstructive retrieval), Churner (operator registration), and Validator/Node endpoints. v2 of the protocol introduces a payment vault and the GetPaymentState RPC on the Disperser, replacing per-account static throughput reservations with a programmatic payments surface. The reference implementation is open source in Go (with a Rust client and SDKs in Rust and TypeScript), licensed Apache-2.0 / MIT, and developed in the open on GitHub.

EigenDA publishes 5 APIs on the APIs.io network. Tagged areas include Blockchain, Data Availability, Ethereum, Restaking, and EigenLayer.

EigenDA’s developer surface includes developer portal, documentation, engineering blog, tooling, code examples, support, and 27 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/eigenda: open an issue to ask a question, or submit a pull request to add artifacts.
