Fnality, a fintech firm building tokenized versions of major currencies collateralized by cash held at central banks, has raised $136 million in a Series C round to expand its blockchain-based wholesale payment systems, the London-based firm said Tuesday. The investment was led by WisdomTree, Bank of America, Citi, KBC Group, Temasek and Tradeweb, with existing backers including Goldman Sachs, UBS and Barclays also participating. Fnality raised $95 million in 2023, a round led by Goldman and BNP Paribas. The firm's settlement infrastructure runs on distributed ledger technology and allows sterling payments to be processed on-chain with central bank money. Backers such as WisdomTree and Bank of America framed the investment as part of a broader shift to modernize financial infrastructure for tokenized assets.
