Covalent is a decentralized, proof-based data infrastructure protocol designed to make blockchain data accessible, verifiable, and sustainable at scale. It offers a unified API called GoldRush that enables developers to access real-time and historical data across over 200 blockchains using a single query endpoint. Covalent ensures the integrity of every data response through cryptographic proofs and introduces "Block Specimens" and "Block Results" to preserve blockchain history in response to Ethereum’s EIP-4444 limitations. At the heart of the protocol is the Covalent X Token (CXT), an ERC-20 token on Ethereum that also settles transactions on Moonbeam, where user-submitted stablecoin payments are converted to CXT via market buy. CXT aligns incentives across the ecosystem: it's staked by node operators and delegators, earned through query fulfillment, and used for governance. The network supports permissionless participation: developers can delegate their CXT to operators without running infrastructure themselves, and CXT holders can vote on proposals affecting protocol direction, data coverage, and system parameters. With over 89% of its 1 billion supply already circulating, CXT powers a well-distributed and economically sustainable network designed for the long-term utility of Web3 data services. Covalent is especially valuable to builders seeking to eliminate the need for custom indexers or centralized APIs, offering predictable query costs, composable endpoints, and verifiable results for mission-critical use cases across DeFi, NFTs, DAOs, and enterprise systems.
