DCJPY tokenised yen deposits (DeCurret DCP network)Updated 15 Oct 2026

DeCurret DCP's network for bank-issued yen deposit tokens, called DCJPY, which banks mint against ordinary deposits and redeem at one yen. It went into production in August 2024 with GMO Aozora Net Bank as the first issuing bank and Internet Initiative Japan using it to trade tokenised renewable energy certificates. In a trial set up in December 2025, SBI Shinsei Bank issued DCJPY that SBI Securities and Daiwa Securities used in March 2026 to settle two real trades in a DeCurret DCP digital bond held on BOOSTRY's ibet for Fin, delivery against payment. Japan Post Bank plans to issue DCJPY by the end of fiscal 2026 and Hokuriku Bank aims to start a service in fiscal 2027. No volumes have been published.
