InfStones

InfStones is an enterprise-grade blockchain infrastructure platform that operates more than 20,000 nodes across over 80 blockchain networks, including Solana. Founded in 2018 and headquartered in Palo Alto, California, the company provides node management, non-custodial staking, and blockchain data APIs to some of the largest organizations in the crypto industry. Its client roster includes Binance, Circle, OKX, Bitget, KuCoin, Lido, Ether.fi, and Stake Stone, among more than 100 enterprise customers worldwide.

What InfStones Builds

InfStones positions itself as a Platform as a Service (PaaS) provider for Web3 infrastructure. Its three core product lines address distinct operational needs.

Node Management is the platform's flagship offering. InfStones deploys and manages nodes on behalf of institutional clients, handling provisioning, monitoring, and maintenance across multi-region, multi-zone environments designed for redundancy. The company claims rapid deployment capabilities with round-the-clock disaster prevention monitoring.

Staking Services allows institutions and large delegators to stake assets through InfStones-managed validators without giving up custody of their tokens. InfStones holds elected super-node positions on proof-of-stake networks including EOS, TRON, and VeChain, and maintains active validator presence on Cosmos, Ethereum, Solana, and dozens of other chains.

Blockchain APIs give developers and applications low-latency access to on-chain data across the supported network roster. The company's EigenLayer Native Restaking API, launched in 2024, is a notable addition targeting institutional access to Ethereum restaking without custom integration work.

Solana Presence

InfStones runs Solana validator infrastructure as part of its multi-chain portfolio. The platform manages Solana nodes for institutional clients who prefer to outsource the operational complexity of validator maintenance, software updates, and key management. This positions InfStones as an infrastructure layer beneath staking protocols and exchanges that need reliable Solana execution without running in-house validator teams.

Company Background and Funding

InfStones was founded in 2018 by CEO Zhenwu Shi, whose stated goal was to build "a rugged, easy-to-use Web3 environment to build a more transparent, intelligent world." The company has raised approximately $156 million across five funding rounds from investors including Qiming Venture Partners, GGV Capital, SIG China, and SoftBank Vision Fund 2.

The most prominent round came in June 2022, when InfStones closed $66 million in an extended Series B co-led by SoftBank Vision Fund 2 and GGV Capital, pushing the company's valuation to nearly $1 billion. This followed a $33 million Series B raise in February 2022, itself preceded by a $10 million raise in August 2021. The rapid funding cadence reflected the institutional appetite for professional blockchain infrastructure services during that period.

The company has been covered by Forbes, TechCrunch, CoinDesk, and Cointelegraph, and sponsored Consensus 2025, indicating continued commercial activity well beyond its initial growth phase.

Security: 2023 Incident and Response

In July 2023, external researchers from dWallet Labs disclosed a vulnerability in the open-source Tailon library that InfStones had deployed across its infrastructure. The flaw exposed port 55555 on affected servers, potentially allowing external parties to imitate viewer access to blockchain binaries and node logs. Of the 237 affected instances, 212 were in development and testing environments, with 25 in production — representing less than 0.1 percent of InfStones' live nodes at the time. No private keys were leaked and no exploitation was detected.

InfStones responded by disabling the affected port and removing Tailon from all systems, rotating all credentials and validator keys, and conducting full data integrity checks across its infrastructure. The company disclosed the incident publicly and acknowledged the contribution of the reporting researchers.

In the aftermath, InfStones implemented structural security improvements: it launched the BlocGuardians Bug Bounty Program to create a formal channel for external vulnerability disclosure, tightened access controls on a need-to-know basis, and initiated the SOC 2 compliance process. The company earned SOC 2 Type I attestation in 2023, then advanced to SOC 2 Type II in January 2025 — a more rigorous standard requiring demonstrated compliance over a sustained operating period, not just a point-in-time assessment.

Recent Activity

InfStones has remained active through 2025 and into 2026 across multiple fronts. On the partnership side, the company was selected by Succinct as a key prover on its decentralized proving network and became a top prover for Boundless Protocol. It also joined Sahara AI's SIWA Testnet as an early participant, was selected by Optimum as a private testnet partner for OptimumP2P, and became a mainnet validator for Somnia Network and IOTA Rebased. InfStones expanded into Monad with both validator and RPC infrastructure, and launched TAO staking on the Bittensor network in collaboration with Yuma.

The company's blog output in September 2026 covers technical guides for institutional operators: validator readiness for the Ethereum Hegota upgrade, Cosmos Hub v28.2 security checklists, and operational considerations for Stacks Bitcoin staking. This content pattern — targeting infrastructure engineers rather than retail users — reflects InfStones' consistent positioning as a B2B platform for professional operators.

Assessment

InfStones is an active, well-capitalized infrastructure business with a verifiable track record running validator and node operations across major blockchain networks. Its enterprise customer list, SOC 2 Type II certification, and continued partnership activity through mid-2026 confirm it remains in operation. The 2023 security incident was material but was handled with public disclosure and followed by concrete remediation steps. For Solana participants — particularly staking providers, exchanges, and protocols that need managed validator infrastructure — InfStones represents one of the more established third-party options in the market.
