Web3 payments infrastructure startup Fun announced the completion of a $72 million Series A funding round, led by Multicoin Capital and SignalFire, with participation from Infinity Ventures, Pharsalus Capital, and Tinder co-founder Justin Mateen, among others. This round was completed in late January, following a $3.9 million seed round in 2022. Fun's main business is providing payment tracks for developers, enabling users to directly exchange crypto assets for fiat currencies such as the US dollar without using centralized exchanges or traditional banks. Currently, the project provides deposit infrastructure for prediction market Polymarket, crypto derivatives platform Lighter, and lending app Aave, processing over $18 billion in payments annually. The new funding will be used to expand its team of approximately 30 people. (Fortune)
