Covalent

Covalent is a modular blockchain data infrastructure company founded in 2018, providing the most comprehensive multichain data APIs and decentralized data availability network for developers, enterprises, and AI agents. Trusted by 70,000+ developers and backed by Binance Labs, Coinbase Ventures, and Maelstrom, Covalent has established itself as one of the foundational data layers for the Web3 ecosystem.

Core Products/Services

Covalent's primary offering is GoldRush, a suite of multichain blockchain data APIs that covers 100+ blockchains. GoldRush provides two self-serve API products: the Foundational API (REST-based historical data across chains, including token balances, NFT assets, transactions, decoded event logs, and traces) and the Streaming API (real-time blockchain events via GraphQL over WebSockets, including OHLCV pricing, DEX pair activity, and wallet movements). GoldRush is SOC 2 compliant with 99.99% uptime SLA and sub-second latency.

Covalent also operates the Ethereum Wayback Machine (EWM), a decentralized network that provides long-term data availability for Ethereum post state-purge. Node operators earn CXT token rewards (~12-15% APY) by running Block Specimen Producers or Block Result Producers. The EWM Light Client allows participants to join the network using a laptop and contribute to Ethereum historical data verification.

For AI-native development, Covalent offers the GoldRush MCP Server, which exposes 50+ GoldRush API tools as Model Context Protocol resources consumable by LLMs such as Claude, Cursor, and Windsurf. Additionally, the AI Agent SDK for TypeScript enables developers to build autonomous multi-agent AI workflows (Zero-Employee Enterprise / ZEE) with built-in onchain data access.
