Syndica is a Solana-only infrastructure company building developer infrastructure for Web3. Its production platform provides fault-tolerant, load-balanced Solana JSON-RPC over HTTP and WebSocket from four global regions, plus ChainStream — a real-time JSON-RPC streaming API that consolidates transaction, slot, and block updates from multiple validators using a "fastest wins" strategy with optional cross-validator verification. Syndica also operates a 0%-commission Solana staking validator running Jito-Solana for MEV optimization, publishes Solana protocol research, and develops Sig — an open-source Solana validator client written in Zig — together with companion libraries (rocksdb-zig, lsquic, boringssl-zig, zstd.zig, base58-zig) under the Apache-2.0 license.
Syndica publishes 2 APIs on the APIs.io network: Solana RPC (WebSocket) API and ChainStream API. Tagged areas include Solana, Blockchain, Web3, RPC, and Streaming.
The Syndica catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
Syndica’s developer surface includes developer portal, documentation, FAQ, support, engineering blog, signup flow, pricing, and 19 more developer resources.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/syndica-io: open an issue to ask a question, or submit a pull request to add artifacts.
