Fun, a developer of payment infrastructure connecting fiat and cryptocurrency systems, closed a $72M Series A funding round in January. The round was co-led by venture firms Multicoin and SignalFire.

Fun provides the payment backbone for platforms including Polymarket, a prediction market platform, and Aave, a major decentralized finance protocol. The infrastructure handles the often-overlooked but critical mechanics of moving money between traditional banking systems and crypto networks. The company operates in a space gaining traction as crypto platforms seek seamless on and off-ramp solutions for users. Payment rails have become a key bottleneck for mainstream adoption, with infrastructure providers serving as essential intermediaries between regulated financial systems and decentralized protocols. Multicoin and SignalFire's co-leadership of the round underscores investor confidence in payment infrastructure as a foundational crypto sector. The $72M valuation reflects the growing importance of these backend systems as crypto platforms scale user bases and transaction volumes.
