Komainu, the C.I.-based digital asset service provider and custodian which is backed by Nomura, has been chosen by CoinShares as custodian for the SEC-approved CoinShares Valkyrie Bitcoin Fund. CoinShares acquired Valkyrie Funds LLC earlier this year as part of its expansion into the U.S. market. This acquisition included the sponsor rights to the Valkyrie Bitcoin Fund, a physically-backed Bitcoin ETF.
