Syndica

Syndica is a Solana-native infrastructure company that provides scalable RPC access, real-time blockchain data streaming, and open-source validator tooling — solving the developer infrastructure gap that prevents engineering teams from building reliably on Solana without running their own nodes.

Background

Founded in September 2021 by brothers Ahmad Abbasi (CEO) and Danial Abbasi, Syndica is headquartered in Houston, Texas. Ahmad previously served as a senior engineer at Messari, the cryptocurrency analytics firm, while Danial was a researcher at 0x Labs, a decentralized exchange infrastructure company. Together, they set out to build the "Cloud of Web3" — a phrase that captures Syndica's core thesis: that blockchain ecosystems need a dedicated infrastructure layer analogous to what AWS and Google Cloud provide to traditional web applications.

In October 2021, Syndica raised an $8 million seed round co-led by Social Capital (the firm founded by investor Chamath Palihapitiya), Jump Capital, and Kindred Ventures. The round also drew participation from Solana Ventures, CoinShares, DeFiance Capital, Spartan Group, MGNR, Resolute VC, Untamed Ventures, and angel investor Joe McCann. The funding validated early demand for purpose-built Solana infrastructure at a moment when most dApp developers were forced to cobble together unreliable self-hosted nodes or accept degraded public endpoints.

Core Products

RPC Nodes

Syndica's primary commercial product is a managed Solana RPC service that lets developers submit transactions, query on-chain state, and stream events without operating their own validator infrastructure. Beyond raw access, Syndica differentiates on observability: the platform exposes advanced logging, per-method usage analytics, and latency telemetry that give engineering teams visibility into how their RPC calls behave under real production conditions. This matters for debugging failed transactions, understanding congestion behavior, and capacity planning — all pain points that generic node providers ignore.

ChainStream

ChainStream is Syndica's real-time blockchain data streaming product, delivered over WebSocket connections. Where standard Solana WebSocket subscriptions provide limited event types, ChainStream unlocks additional subscription methods including transactionsSubscribe, blockSubscribe, and encodedBlockSubscribe, enabling applications to receive full transaction and block payloads as they confirm on-chain.

The architectural design behind ChainStream is notable: rather than relying on a single validator feed, it connects to multiple Solana validators simultaneously and applies a "fastest wins" strategy — delivering the earliest notification from whichever validator processes an event first. The system also performs deduplication to eliminate duplicate events and backfills data if any individual source misses an update. The result is a more reliable, lower-latency stream than a single-node WebSocket connection can provide. Within the same AWS region as a Syndica data center, round-trip latency from geyser interface to client sits at or below 10 milliseconds. Across typical public internet links, developers can expect 50 to 100 milliseconds end-to-end.

ChainStream supports rich filtering: accounts can be matched via all, oneOf, or exclude matchers, and a verified flag gates delivery on multi-validator confirmation, useful for applications that need stronger finality guarantees before acting.

Sig: Open-Source Validator Client in Zig

Syndica's most ambitious engineering initiative is Sig, an open-source Solana validator client written in Zig, a modern low-level systems language. Sig was introduced with a specific philosophical departure from the existing validator codebase: it optimizes for reads-per-second (RPS) rather than transaction throughput.

The rationale is grounded in data. Syndica analyzed two years of call patterns across a broad cross-section of dApps and found that 96.1% of all RPC calls are reads. For every sendTransaction write call, roughly 25 read calls are triggered upstream. Read-heavy methods like getProgramAccounts, getTransaction, and getSignaturesForAddress saturate existing nodes at only 60 to 301 calls per second before degradation begins — approximately 250 times less headroom than lightweight methods like getHealth. Sig is designed from the ground up to handle this read-dominant load profile more efficiently.

Zig was chosen for several concrete reasons: it supports custom memory allocators that enable hardware-level optimization important for distributed systems, provides direct C and C++ interoperability without wrapper overhead, and enables compile-time meta-programming that shifts computational cost from runtime to compilation. Zig has also seen adoption by Uber, AWS, and CloudFlare, giving it credibility beyond academic interest.

Beyond performance, Sig addresses a structural risk in the Solana network. At launch, Solana had only two active validator clients — a stark contrast to Ethereum's nine. A bug in a single dominant client can cause network-wide outages. Client diversity is the standard mitigation. Sig is designed to be the first implementation of the Solana validator client simple enough to read and contribute to, with accessibility as a first-class goal alongside performance.

As of mid-2025, the Sig team had completed the gossip protocol (network discovery and metadata propagation), AccountsDB, Blockstore, and the Shred Collector — progress presented at Breakpoint 2024. The SVM and runtime were implemented subsequently. Active development continues on the full replay stage, consensus layer (Tower BFT), RPC layer, GulfStream transaction forwarding, and the leader stage. The repository is publicly available at github.com/Syndica/sig.

Staking Validator

Syndica also operates a Solana validator that accepts stake from token holders. The validator runs the Jito-Solana client, which enables MEV capture in addition to standard inflation rewards. Commission is set at 0%. Stakers retain self-custody — SOL is not wrapped, bridged, or locked — and can initiate unstaking at any time, subject to the standard Solana epoch transition window of roughly two to three days on mainnet. The validator identity account is SyndicAgdEphcy5xhAKZAomTYhcF8xhC7za2UD9xeug and vote account is SyNdica7qx3njeVKNgXvV7KC1NjPYNS4fyb3NxgevLH.

Fit Within the Solana Ecosystem

Syndica operates exclusively on Solana, which is unusual among infrastructure providers — most hedge across multiple chains. This single-chain focus allows deep specialization: ChainStream's multi-validator architecture, Sig's Solana-specific Zig implementation, and the observability tooling are all built around Solana's particular transaction model and validator topology.

The company's blog publishes regular research on Solana ecosystem metrics including DeFi activity, DePIN growth, onchain developer counts, and dApp revenue — with reports published through at least June 2026, reflecting an organization actively engaged with the ecosystem rather than one in maintenance mode.

For developers, Syndica's value proposition is the combination of reliable RPC access, real-time streaming, and monitoring tooling in a single platform — an infrastructure stack that removes the need to stitch together multiple providers and self-manage node infrastructure.
