What Syndica Is and the Problem It Solves

Decentralized applications built on Solana depend on reliable, low-latency access to blockchain state. A single self-hosted RPC node creates a single point of failure: it can become overloaded by read traffic, fall behind the chain tip, and degrade user experience. Running production-grade infrastructure—redundant nodes, global routing, caching, observability—is expensive and operationally demanding for most development teams.

Syndica was founded in 2021 in Houston, Texas to solve this problem. The company focuses exclusively on the Solana ecosystem, offering a managed infrastructure stack that covers the three main touchpoints a Solana application needs: reading chain state via JSON-RPC, subscribing to real-time blockchain events, and accessing a staking validator with direct onchain accountability.

By 2025 the platform had grown to serve more than 6,000 developers, and Syndica had established itself as a primary metrics and infrastructure provider for the Solana ecosystem.

How the Infrastructure Works

Solana RPC

Syndica's RPC product routes calls through a global edge network deployed across four regions: Northern Virginia (us-east-1), Oregon (us-west-2), London (eu-west-2), and Singapore (ap-southeast-1). Requests from a client are automatically directed to the nearest edge gateway.

A regional caching layer intercepts frequently accessed Solana data—account state, token balances, and similar high-read endpoints—so that many reads never reach a validator at all. Cache misses are forwarded to a managed validator cluster that operates with redundancy and automatic failover, ensuring continuous availability even when individual nodes have issues.

This two-layer design—edge cache in front of a redundant validator cluster—delivers consistently lower latency than a single self-hosted node and removes the operational burden of maintaining validator software and hardware. The free tier includes 10 million RPC calls to allow developers to integrate and test without upfront cost.

ChainStream

ChainStream is Syndica's real-time streaming API. Rather than polling a JSON-RPC endpoint for new transactions or block updates, applications subscribe to ChainStream and receive data as it is produced on the network: transactions, slots, blocks, and account updates streamed directly from validators.

This push model is particularly valuable for trading bots, liquidation engines, indexers, and any application that needs to react to onchain events with minimal lag rather than discovering them through repeated polling.

Staking Validator

Syndica operates a production Solana validator (identity SyndicAgdEphcy5xhAKZAomTYhcF8xhC7za2UD9xeug, vote account SyNdica7qx3njeVKNgXvV7KC1NjPYNS4fyb3NxgevLH) with 0% commission on both inflation and MEV rewards. The validator runs the Jito-Solana client to capture additional MEV-based yield. Delegators retain self-custody of their SOL—no wrapping or locking required—and activation follows standard Solana epoch timing of approximately two to three days.

Sig: An Open-Source Validator Client in Zig

Alongside its commercial infrastructure, Syndica develops Sig, an independent Solana validator client written in Zig. Sig is not a fork of the reference Rust implementation; it is a ground-up reimplementation with a different performance priority.

The guiding observation behind Sig is that approximately 96% of all calls made to a Solana node are reads, not writes. The reference Rust client was designed to prioritize transaction processing throughput. Sig inverts this by optimizing reads-per-second (RPS), targeting the five high-volume read methods that most frequently become bottlenecks: getMultipleAccounts, getTokenAccountsbyOwner, getTransaction, getSignaturesforAddress, and getProgramAccounts. Under current conditions, Solana nodes handle roughly 60 getProgramAccounts requests per second before degrading; Sig's architecture is built to substantially improve that ceiling.

Why Zig

Syndica chose Zig for several compounding reasons. Zig delivers C-level performance with explicit memory management through custom allocators, which is critical for a latency-sensitive system. It interoperates directly with C and C++ libraries without wrapper overhead, allowing Sig to use optimized system calls such as recvmmsg and sendmmsg for high-throughput network I/O. Zig's compile-time execution feature moves computations from runtime to compile time, reducing per-request overhead. And compared with Rust, Zig produces cleaner, more readable code—an important factor for attracting external contributors to an open-source validator project.

The initial implementation began with the gossip layer (network discovery and peer metadata propagation), followed by replay and consensus, with the RPC and leader stages on the roadmap. Longer-term optimizations planned for Sig include io_uring for zero-syscall filesystem I/O and eBPF XDP for kernel-level network packet processing.

Client Diversity

Prior to Sig, Solana operated with only two active validator client implementations, both sharing significant code. Ethereum, by comparison, maintains nine diverse implementations, which limits the blast radius of any single software vulnerability. A fully independent third client in a different language reduces the risk of a correlated network outage from a shared bug. Sig is the first Solana validator client implemented in a language other than Rust.

Research and Ecosystem Analytics

Beyond infrastructure tooling, Syndica publishes regular deep-dive research reports covering Solana developer activity, onchain transaction volume, DeFi protocol metrics, DePIN project growth, and dApp revenue trends. These monthly reports are published on the Syndica blog and are used as primary reference data across the Solana ecosystem.

Team and Funding

Syndica was co-founded by CEO Ahmad Abbasi and Danial Abbasi. The company raised an $8 million seed round in 2021, co-led by Chamath Palihapitiya's Social Capital. The team is headquartered in Houston, Texas.

Solana Ecosystem Fit

Syndica sits in the foundational infrastructure layer of the Solana ecosystem. Its RPC and ChainStream products serve the application layer—wallets, DEXs, NFT platforms, data indexers, and trading systems—that depend on fast and reliable access to chain state. Its Sig validator client contributes to the health and decentralization of the validator layer itself. Together these products position Syndica as both a commercial infrastructure provider and an active open-source contributor to Solana's long-term resilience.
