Rock’n’Block is a Web3-native development studio whose website highlights its capabilities in prediction market development and blockchain data streaming infrastructure. It is not a general-purpose developer-tool SaaS in the traditional sense, but rather a custom development service provider for project teams, covering protocols, frontends, backends, on-chain contracts, data pipelines, and mainnet deployment.
For prediction markets, Rock’n’Block covers Core Protocol, CLOB trading engines, settlement logic, trading terminals, analytics tools, trading automation, points and referral systems, as well as real-time and historical data infrastructure. Its data streaming solutions are built around Modified Nodes, Buckets, Firehose, gRPC, Substreams, and SQL Sink, emphasizing low latency, parallel processing, cursor-based streaming, reorg handling, SQL database integration, and a self-hosted data layer. The chains listed on the site include Ethereum, Solana, TON, BNB Chain, Polygon, BASE, XDC, and others. Case-study tech stacks include Go, Rust, Solidity, React, Python, TypeScript, GraphQL, PostgreSQL, Django, and more.
The official website does not disclose fixed pricing. Its process starts with requirements gathering, after which the CTO and technical leads define the technical specification, break the project into modules, and estimate the required hours. When the scope is clear, Rock’n’Block uses a Fixed-Price model; when requirements are likely to change, it uses Time and Material. The delivery process includes requirements analysis, specification, estimation, development, testnet validation, and mainnet deployment, with documentation and ongoing support terms available when needed.
Its main strength is broad coverage, making it suitable for taking complex Web3 products from zero to one. The site showcases cases such as Blum, SwapX, Squirrel Wallet, and K9 Finance, along with specific tech stacks and performance metrics. The data infrastructure section gives relatively detailed coverage of reorg handling, caching, parallel indexing, and avoiding vendor lock-in. The downside is that the public materials still lean toward marketing: there is no directly testable API documentation, SDK examples, SLA, pricing range, or clear boundary around open-source code. For developers, assessing cost and migration difficulty will require further communication.
Rock’n’Block is best suited to Web3 teams with relatively sufficient budgets that need custom prediction markets, DEXs, wallets, RWA products, or on-chain data infrastructure. It may also suit public chains looking to provide a high-performance indexing layer for ecosystem developers. The main website does not state whether it is accessible from mainland China, nor does it disclose payment methods. Given that its business sits in the Web3 and overseas service space, China-based teams should confirm website connectivity, contracting entity, payment methods, and compliance requirements in advance. Alternatives to consider include Goldsky, Envio, Subgraph/Substreams, or building an in-house solution.
