Solana data infrastructure for developers. Fast APIs, real-time streams, and historical data without the infrastructure overhead.
We believe developers should focus on building products, not infrastructure. Every Solana team shouldn't have to solve the same data problems—parsing transactions, indexing accounts, managing storage at scale.
BlockSignal provides the data infrastructure so teams can ship faster. Query historical transactions, stream real-time events, and access normalized blockchain data through simple APIs.
The principles that guide how we build
Everything we build starts with the developer experience. Clear docs, intuitive APIs, and helpful error messages.
Latency compounds. We obsess over every millisecond because your users notice the difference.
Uptime isn't a feature—it's a requirement. We build systems that stay up when everything else goes down.
We follow the Solana RPC spec. No proprietary lock-in. Switch providers without rewriting code.
