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.
