Helius
Helius is the ultimate developer platform for building on Solana. Effortlessly navigate on-chain data with enhanced Solana APIs, webhooks, and best-in-class Solana RPCs. Join the ranks of top Solana developers, today. Helius was built to make your life easier. No need to worry about parsing or interpreting on-chain data, hunting for reliable RPC nodes, or building costly pipelines for tracking real-time events. Helius SDK is the most complete & powerful SDK for building on Solana. View our documentation to learn more about how you can leverage it to use our services. Build event-driven systems and on-chain automation. Watch for on-chain events and react to them in real-time, sub-second latencies. You can watch up-to 100k addresses in a single webhook! We make it easy to interpret and query historical Solana data. Instead of opaque hashes, our APIs allow you to see the context of on-chain transactions, whether they are NFT listings, DEX swaps, DeFi loans, or DAO votes.

Axiom
Access more data at a lower cost on-chain, made trustless by the power of ZK. Use transactions, receipts, and historic states in your smart contract. Axiom supports computing over the entire history of Ethereum, verified by ZK proofs on-chain. Combine data from block headers, accounts, contract storage, transactions, and receipts. Specify computation over the history of Ethereum in Typescript with the Axiom SDK. Access our library of ZK primitives for arithmetic, logic, and array operations, verifiable on-chain. Axiom verifies query results on-chain with ZK proofs and sends them to your smart contract callback. Build truly trustless on-chain apps with ZK-verified results from Axiom. Trustlessly evaluate and pay protocol participants without external oracles. Reward protocol contributions based on on-chain behavior, even in external protocols. Slash for bad behavior according to custom criteria.

Synternet
Today, builders face barriers to accessing real-time, reliable data across different blockchains. They rely on fragmented, centralized data sources and unreliable infrastructure, slowing development and adoption. Synternet offers a solution by providing permissionless real-time data infrastructure that empowers developers to build the next generation of cross-chain DApps by utilizing composable data streams. Synternet and its data layer power data infrastructure for projects building in AI, DeFi, DePIN, trading, IoT, gaming, governance, and other spaces. Access real-time data to power complex models on-chain. Build decentralized machine learning models that can leverage cross-chain data and events. Verify ownership by cross-referencing on-chain data. This enables checking provenance across multiple sources of truth, regardless of what chain you’re using. Stream real-world sensor data to your blockchain application.
