Payment infrastructure startup Fun has successfully closed a $72 million Series A funding round led by Multicoin Capital and SignalFire, as reported by The Block and Intellectia.AI. The round included new investors Infinity Ventures, Pharsalus Capital, and angel backer Justin Mateen, co-founder of Tinder. This funding round represents a significant investment in the company's vision to create unified payment rails for both fiat and cryptocurrency transactions. The capital will support Fun's expansion plans, including the establishment of a new Singapore office and potential acquisitions to strengthen its market position.
Fun has demonstrated strong operational scale, processing more than $18 billion in annual transaction volume across its network, according to The Block reporting. The company operates as a neutral, API-first infrastructure provider, handling deposits and withdrawals for high-growth consumer platforms including prediction markets like Polymarket, social applications such as Lighter, and decentralized finance platforms including Aave. This substantial transaction volume validates the company's position in the growing market for unified payment solutions and highlights its critical position in the rapidly growing consumer finance market.
As reported by The Block and Intellectia.AI, Fun positions itself as a neutral, API-first "money layer" for both Web2 and Web3 products. The company's infrastructure abstracts away the complexity of banking partners, stablecoin liquidity, and compliance requirements, allowing applications to offer seamless deposits and withdrawals in local currencies and digital assets through a single API. This technological edge significantly lowers the barrier for users to access DeFi protocols and enables platforms like Polymarket to move funds between dollars, stablecoins, and onchain markets without direct interaction with traditional banking interfaces.
According to The Block and Intellectia.AI reporting, Fun's infrastructure model addresses the growing demand for seamless payment integration across traditional and decentralized financial systems. With rising interest in stablecoin payments, Fun's infrastructure is positioned to attract more traditional capital into the crypto market, further solidifying its pivotal role in the future financial ecosystem. The company's focus on consumer-facing applications where users expect instant settlement and low friction positions it to benefit from the increasing adoption of stablecoin payments, with estimates suggesting approximately $60 billion was spent on legacy remittance fees in 2025 alone.
