Building and maintaining indexing infrastructure is inefficient, expensive, and less performant. Operator makes it easy for developers to build blockchain products that leverage data from blockchains and decentralized storage services like IPFS and Arweave, all through a simple SQL-based API.


Developers use Apibara to stream on-chain data and build their application’s backend. Apibara supports any type of data like events, transactions, and storage changes.


GraphQL is a data query language for optimized yet flexible and thorough APIscripting and scalable scope.Developers can query for the relationships of a target data item and present it on the client side with a single request, whereas regular Restful APIs wouldtrigger multiple URL requests/loads.Using GraphQL results in quicker and wider data serving without increasednetwork usage/requests.


Covalent issues free APIs to connect projects with the data they require, with support for 40 blockchains.Developers can use the Covalent API and create query apps that serve dynamicdata on request.Covalent also rolls out research training programs with the aim of making Web3development knowledge mainstream.


Presearch is an ecosystem of tools, including a search engine, a staking service for the PRE token, nodes, and a marketplace.Users can enjoy token incentives when searching using Presearch as the default.Developers can run Presearch nodes to increase the decentralized data service’s efficiency while making the network censorship-resistant.


Helius aims to rid the complexity of building on the Solana chain by providing developers APIs for transactions and NFTs, webhooks, and turbocharged RPCs. Developers can build a service that fires notifications or triggers other events when something of effect is registered on the Solana blockchain – such as when a known collector buys new NFTs.


Goldsky lets you build real-time data streams for your applications without the hassle of managing complex blockchain and data streaming infrastructure. Goldsky can index a blockchain or subgraph, transform the data to fit your needs, and stream the results into a data warehouse, webhooks or an API, all in real-time.

The Graph

The Graph saves developers’ effort and resources building their own servers or performing long processes to search through data by indexing and querying data from NEAR and EVM blockchains. Users can query liquidity data from published subgraph services like Sushi or Messari. Developers can create, publish, and distribute subgraphs to make interchain data queries easier.
