InfStones

InfStones is an enterprise-grade Platform as a Service (PaaS) blockchain infrastructure provider that manages node operations, staking, and API access across more than 80 blockchain networks. Founded in 2018 and headquartered in Palo Alto, California, the company positions itself as a one-stop infrastructure layer for institutions, exchanges, and developers who need reliable, multi-chain operations at scale without building and managing their own node infrastructure.

Background and Scale

InfStones was founded in 2018 by Zhenwu Shi and Jonathan Shi. Over the following years the company grew its footprint to more than 10,000 active nodes across 80+ supported networks, with more than $500 million in total tokens delegated to the platform. Its client list reads as a cross-section of the institutional crypto industry: Binance, OKX, KuCoin, CoinList, BitGo, Chainlink, Lido, EtherFi, Polygon, and Harmony are among the organizations that have relied on InfStones infrastructure.

The operational track record spans more than 1,000 consecutive days, a figure the company highlights to underscore uptime consistency — a critical requirement for exchanges and custodians whose own products depend on uninterrupted blockchain connectivity.

Core Products

Node Management. InfStones' primary offering is managed node deployment across its supported network list. Clients can launch and monitor nodes without maintaining bare-metal server operations themselves. The platform handles redundancy through multi-region, multi-zone deployments and provides 24/7 monitoring and disaster-prevention tooling. This is structured as a PaaS model, meaning clients interact with nodes through InfStones' management layer rather than configuring raw infrastructure directly.

Staking Services. InfStones operates staking services for more than 30 tokens, including Solana. Stakers can delegate to InfStones validators through the platform at app.infstones.com/solana for SOL. The staking product extends to liquid staking integrations, with Lido and EtherFi listed as partners, and includes EigenLayer restaking functionality for Ethereum-based assets. Reward claiming and delegation management are handled through the same interface.

API Services. InfStones provides RPC and API access to supported blockchains, including Ethereum JSON-RPC methods covering more than 40 endpoints and Cosmos gRPC and REST interfaces. These API services are aimed at developers building decentralized applications who need reliable, low-latency data access without running their own archive or full nodes. The platform emphasizes data reliability and speed as key differentiators over self-hosted alternatives.

Blockchain Intelligence. In July 2026, InfStones launched an integration within the Claude Connectors Directory called InfStones Blockchain Intelligence. The connector enables users to query on-chain data — such as diagnosing failed transactions and tracing fund flows — through natural-language prompts inside Claude, without requiring developers to write custom queries or use separate blockchain explorer tools.

Solana Integration

Solana is a supported network within InfStones' infrastructure stack. The platform offers SOL staking through its dedicated Solana staking interface and operates within the broader Solana validator ecosystem. Lido and EtherFi, both of which are significant stakeholders in Solana liquid staking, are listed among InfStones' institutional partners, reflecting the company's position as a backend infrastructure provider for protocols that in turn serve Solana stakers.

Security and Compliance

InfStones earned SOC 2 Type II attestation on January 3, 2025. This attestation covers the five Trust Services Criteria — security, availability, processing integrity, confidentiality, and privacy — and validates that InfStones' security controls were not only properly designed (as demonstrated by an earlier SOC 2 Type I certification) but consistently implemented and effectively operated over a sustained period. For institutional clients operating under compliance requirements of their own, the SOC 2 Type II designation provides independent third-party verification of InfStones' operational security practices.

Funding History

InfStones has raised $156 million in total funding across five rounds from 15 investors since its 2018 founding. The most notable financing was a $66 million extended Series B announced in June 2022, led by SoftBank Vision Fund 2 and GGV Capital, with participation from INCE Capital, 10T Fund, SNZ Holding, and A&T Capital. That round followed a $33 million Series B closed in February 2022, meaning the company raised approximately $99 million across a roughly four-month window during the 2022 fundraising cycle. The $66 million round was described at the time as pushing InfStones toward unicorn territory, though the company has not disclosed a specific valuation publicly.

Liang Xinjun is the company's angel investor, and the broader investor base includes Qiming Venture Partners and SIG China in addition to the SoftBank and GGV-led round participants.

Ecosystem Role

InfStones occupies the infrastructure layer of the multi-chain ecosystem rather than any single network's application or DeFi layer. Its business model — providing managed nodes, staking, and API connectivity to exchanges, custodians, DeFi protocols, and developers — means its scale and reliability are largely invisible to end users but directly underpin services that millions of crypto users interact with daily. The company's client concentration in major centralized exchanges (Binance, OKX, KuCoin) and institutional custodians (BitGo, CoinList) reflects a deliberate focus on enterprise contracts rather than retail staking markets.

Within Solana specifically, InfStones participates as both a staking infrastructure provider and a connector for on-chain data access, serving institutional clients that require compliant, audited, enterprise-grade Solana infrastructure rather than building and maintaining their own validator or RPC operations.
