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.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles EigenDA the way a machine reads it — 6 machine-readable artifacts across 5 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — EigenDA scores 17.3/100 (emerging), with a separate agent-readiness read of 7/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile EigenDA
Each block below is one kind of artifact we hold for EigenDA. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 5
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
EigenDA Disperser API
gRPC API exposed by the EigenDA Disperser. Rollups submit raw blobs to DisperseBlob, then poll GetBlobStatus until the blob is confirmed and dispersed across the operator set. v...
EigenDA Retriever API
gRPC service that fans out chunk requests to EigenDA operator nodes and reconstructs the original blob from the retrieved chunks via the RetrieveBlob RPC.
EigenDA Relay API
gRPC service exposing GetBlob, GetChunks, and GetValidatorChunks against blobs stored by the relay layer. Relays sit between rollups and validators and front the read path for p...
EigenDA Churner API
gRPC service that handles operator registration via the Churn RPC. The Churner decides whether new operators may join the EigenDA operator set and which existing operators are e...
EigenDA Validator Node API
gRPC API served by EigenDA operator nodes. Validators receive chunk dispersals from the Disperser, sign aggregated attestations, and serve chunk retrieval. v2 introduces node_v2...
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
