Syndica
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.

99.99% uptime SLA on production endpoints; billions of RPC requests served monthly
10M free RPC requests per month entry tier; enterprise pricing via Cost Estimator
Open-source Sig validator client written in Zig (Apache-2.0) for read-optimized validator operation
Solana staking validator with 0% commission, MEV optimization via Jito-Solana client
Research arm publishing Solana protocol and consensus research
High-frequency Solana trading
Power on-chain trading bots, market makers, and liquidation engines with low-latency ChainStream notifications — production users have cut limit-order time-to-fill from 10s to 300ms.
DEX and DeFi backends
Stream account, program, and signature updates for AMMs, perps, and lending protocols without running self-hosted validator infrastructure.
Wallet and explorer infrastructure
Serve high-volume getAccountInfo, getTransaction, and getSignaturesForAddress traffic from Syndica's load-balanced HTTP RPC fleet.
Indexers and data warehouses
Continuously ingest Solana transactions, slots, and blocks via ChainStream into ClickHouse, BigQuery, or self-hosted Postgres for analytics.
NFT mint and marketplace tooling
Subscribe to program-derived account changes for real-time mint, list, sale, and bid detection.
Solana staking
Delegate SOL to the Syndica validator (0% commission, Jito-Solana client, MEV optimization) for self-custody staking rewards.
Solana protocol R&D
Build on top of, or contribute to, Sig — Syndica's open-source Zig validator client — and consume its companion libraries (rocksdb-zig, lsquic, boringssl-zig).
Solana mainnet-beta
Drop-in replacement for `api.mainnet-beta.solana.com` HTTP and WebSocket endpoints.
Solana web3.js
Use Syndica's RPC URL directly with `@solana/web3.js` `Connection` and `PublicKey` flows.
solana-cli
Configure `solana config set --url https://solana-mainnet.api.syndica.io/api-key/` for CLI access.
Anchor framework
Point Anchor's provider at a Syndica RPC URL for Solana program development.
Helius / Triton / QuickNode workflows
Mix-and-match providers — Syndica positions itself as the Solana-only specialist alongside multi-chain RPC vendors.
Jito-Solana
Syndica's validator runs the Jito-Solana client for MEV-aware block production.
GitHub
Open-source Sig validator and companion Zig libraries are developed publicly under the Syndica GitHub organization.
Solana RPC (Shared)
Multi-tenant Solana JSON-RPC HTTP and WebSocket endpoints with 10M free monthly requests, credential-level rate limits, and global edge routing.
ChainStream
Premium real-time Solana data streaming API consolidating updates from multiple validators with "fastest wins" routing and optional cross-validator verification.
Enterprise / Dedicated
Custom RPC capacity, dedicated nodes, ChainStream throughput, and SLA — priced via the Cost Estimator and direct sales.
Staking
Delegate SOL to the Syndica validator (0% commission, Jito-Solana, MEV optimization) with full self-custody.
Sig (Open Source)
Syndica's open-source Zig Solana validator client, plus companion libraries — free to use and contribute to.
Research
Syndica Research Library — public protocol and consensus research alongside the Research Blog tag.

description: ChainStream is Syndica's real-time Solana data streaming API. It consolidates updates from
multiple validators using a "fastest wins" strategy so the subscriber benefits from the lowest-latency
notification across the validator set, and offers an optional `verified` parameter that delivers only
transactions confirmed by multiple validators at `processed` commitment. ChainStream uses JSON-RPC
2.0 over WebSocket (`wss://chainstream.api.syndica.io/api-key/<API_KEY>`) and supports
`transactionsSubscribe`, `slotsSubscribe`, and encoded `blocksSubscribe` against `solana-mainnet`
(devnet coming). Production users have cut limit-order time-to-fill from 10s to 300ms with it.
