Columbia's new bank Littio is converting its blockchain network from Ethereum to Avalanche to launch a product called Yield Pots that allows users to earn interest on their dollar deposits. Littio is providing exposure to Yield Pots through a partnership with OpenTrade, a London-based company that develops income products using real-world assets such as stablecoins and U.S. treasury securities. Littio's Yield Pots, which launched in February, is understood to have traded more than $80 million. Handler said Littio holds and reinvests 11 million to $13 million a month in the OpenTrade vault.
