As crypto prices soar to all-time highs, venture investors are pouring capital into a red-hot corner of the blockchain industry: infrastructure for stablecoins, which are cryptocurrencies designed to hold a fixed 1:1 peg to fiat currencies like the U.S. dollar. This climate has helped BVNK, a U.K.-based stablecoin infrastructure company, raise a $50 million, all-equity Series B funding round led by the crypto-focused megafund Haun Ventures, with participation from Coinbase Ventures and existing investor Tiger Global. The round values BVNK at around $750 million, according to a source familiar with the deal.
