London-based crypto software firm OneBalance has secured $20 million in a Series A funding round led by venture capital firms Cyber Fund and Blockchain Capital. The round also included investments from Mirana Ventures and L2IV, bringing OneBalance’s total funding to $25 million. The company chose not to disclose its valuation in this latest round.

Founded in 2024, OneBalance is focused on developing software that enables software engineers without a crypto background to build applications incorporating cryptocurrency features.

The company’s flagship product, launched this week, is a toolkit comprising software tools and libraries that allow developers to integrate functionalities such as trading memecoins, token swaps, and peer-to-peer payments into their applications.

Currently, the toolkit supports Ethereum, Polygon, and other Ethereum Virtual Machine blockchains, with plans to add Solana support by the end of June. OneBalance intends to generate revenue by charging a small fee on each transaction processed through platforms that use its toolkit.

OneBalance joins a growing list of crypto companies aiming to simplify application development in the space. Firms like Reown and Privy offer developer kits to ease crypto wallet integration, while Helius focuses on reducing complexity for developers building on Solana. The fresh funding will be used to enhance the toolkit’s capabilities by supporting additional blockchains, further enabling developers to build seamless crypto-enabled applications.
