Summary
OneBalance has secured $20 million in Series A funding led by venture capital firms Cyber Fund and Blockchain Capital, according to an announcement on June 11, 2025. The London-based crypto software company, founded in 2024, now has raised $25 million in total funding. Mirana Ventures (the venture arm of cryptocurrency exchange Bybit) and L2IV participated in the round. The company declined to disclose its post-money valuation.
OneBalance's core offering is a developer toolkit—a collection of software libraries and tools—that abstracts away blockchain complexity for non-crypto-native engineers. The toolkit, which launched on June 11, 2025, enables developers to integrate cryptocurrency functionality into applications, including memecoin trading, token swaps, yield generation, and peer-to-peer payments. The product launches with native support for Ethereum and Polygon (Ethereum Virtual Machine-compatible blockchains), with Solana support scheduled for the end of June 2025.
CEO Stephane Gosselin framed the market opportunity around enterprise adoption of blockchain technology. Major technology companies including Meta and Google are exploring stablecoin integration, yet lack the internal infrastructure to reliably execute blockchain transactions at scale. "They don't necessarily know how to be able to execute reliability on-chain, and the last thing they want to do is start to expose a lot of that complexity to their users," Gosselin told Fortune. OneBalance's toolkit allows enterprises to "focus on their product and how to create the user experience, while having a reliable way to do transfers, swaps, and earning yield."
The company's revenue model is transaction-based: OneBalance charges fees for each transaction processed through platforms integrating its toolkit. "We want to make money when our customers make money," Gosselin stated. The Series A proceeds will fund headcount expansion and product development, positioning the company to capture demand from Fortune 500 companies and mainstream software firms entering the blockchain space.
