Infstones, a California-based Blockchain infrastructure provider, announced on Thursday that it has secured $33M in Series B financing from Susquehanna International Group (SIG), Dragonfly Capital, Qiming Venture Partners, DHVC, A&T, INCE Capital, and Value Internet Fund. 

To date, the US company has raised total funding to $45M.

How will the funding be used?

The capital will enable the Blockchain company to triple its team and expand support to more than 100 chains and protocols. The company is also planning to advance its platform and continue technology research.

“With InfStones, we’re created the world’s most powerful blockchain development platform with robust API features that gives developers integration and access to over 50 blockchains out of the box. InfStones gives more cross-chain access than any other platform in the world and includes Ethereum, Binance Smart Chain, Cardano, Polygon, Polkadot, Solana, Chainlink, and many more. . We don’t compromise reliability, scalability, or speed despite having one of the world’s most easy to use, one-click deployment features. Our goal is to bring the AWS experience to Web3.” says Dr. Zhenwu Shi, CEO of InfStones.

Blockchain infrastructure service

Founded in 2018 by Zhenwu Shi, InfStones provides decentralised blockchain infrastructure service on one integrated platform. 

The company aims to bring down the barriers to connecting with the blockchain, allowing clients to quickly build their applications on a large variety of blockchain networks. 

Currently, InfStones provides services to a wide variety of institutional clients and supports tens of thousands of nodes on more than 50 chains, including Ethereum, Binance Smart Chain, Cardano, Polygon, Polkadot, Solana, Chainlink, and more.

Besides funding, the company has also launched a new front-end user interface that lets clients easily deploy nodes within minutes. 

The public API is currently available for Binance Smart Chain (BSC), BSC Archival Data, Ethereum, and NEO, with support coming for Cosmos and other chains.

The company has offices in Beijing, the United States, and Canada.


Started as a trading firm Susquehanna International Group of Companies (SIG) is one of the largest privately-held financial institutions in the world. 

“The next phase of blockchain will be focused on ease of use, not only for end-users but also for the builders. InfStones is simplifying a process that has been historically complex, without compromising reliability, security, scalability, and control. This will lead the way for a new era of blockchain growth that will change the way companies across a variety of verticals enter and build in the space,” says Michael Yuan, Partner at SIG.

“Just as AWS has made it easy for companies to deploy applications across servers, storage, and databases, InfStones is making it simple to deploy nodes, APIs, and other services. Their platform helps reduce the barriers to entry for new companies that are looking to incorporate blockchain technology into their stack,” said Tom Schmidt, General Partner at Dragonfly Capital.
