Crypto payment infrastructure startup Fun has announced the completion of a $72 million Series A round in January, with Multicoin Capital and SignalFire leading the financing. The raise highlights continued investor interest in infrastructure providers that support the movement of value between traditional finance and digital assets.
Building fiat and crypto on- and off-ramps
According to the company, Fun provides platforms with channels for fiat and crypto deposits and withdrawals. These services play a key role in enabling platforms to handle user fund flows more efficiently, especially where both conventional payment systems and digital asset rails need to coexist.
Funding aimed at growth and broader enterprise adoption
Fun said it plans to use the new capital to expand its team and make it easier for more non-crypto-native enterprises to integrate its payment infrastructure. The strategy suggests a push beyond core crypto businesses toward a wider range of companies seeking access to digital asset payment capabilities.
As more enterprises explore stablecoins, on-chain settlement, and crypto-linked payment use cases, infrastructure providers that can bridge fiat and digital assets are attracting increasing attention. Fun’s latest funding round signals confidence from investors in the long-term potential of crypto payment infrastructure.
