aid: eigenda name: EigenDA description: >- 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. type: Index position: Provider access: 3rd-Party image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg tags: - Blockchain - Data Availability - Ethereum - Restaking - EigenLayer - Rollups - Layer 2 - Web3 - gRPC - Decentralized Infrastructure - KZG Commitments - Cryptography url: https://raw.githubusercontent.com/api-evangelist/eigenda/refs/heads/main/apis.yml created: '2026-05-24' modified: '2026-05-24' specificationVersion: '0.20' apis: - aid: eigenda:disperser-api name: EigenDA Disperser API description: >- gRPC API exposed by the EigenDA Disperser.
