关于 Covalent (CQT)
Covalent provides an API for any individual, company or decentralized application to access blockchain data. The Covalent team created a software that indexes and stores smart contract, wallet, block and transaction data from multiple blockchains, including Ethereum, Polkadot and Elrond. Covalent’s API helps developers easily access billions of data points that can be used for their specific projects and needs. The Covalent Query Token (CQT) is Covalent’s native cryptocurrency and is the main method of payments between developers needing data and validators who answer those queries. Holding and staking CQT also enables participants to vote on protocol upgrades to the network.
