Metaplanet has officially launched Metaplanet Securities after completing the acquisition of Siiibo Securities for JPY 2.1 billion. The new subsidiary, operating under a Type I Financial Instruments Business Operator licence from Japan’s Financial Services Agency, will focus on structuring and distributing regulated Bitcoin-backed financial products.
Rather than merely holding Bitcoin on its balance sheet, Metaplanet intends to use its growing treasury—which reached 43,000 BTC after a 2,823 BTC purchase in Q2—as collateral for digital corporate bonds and structured credit instruments. The initiative, dubbed Project Nova, is being developed in partnership with yen stablecoin issuer JPYC and tokenization platform Progmat. The framework aims to combine Progmat’s security token infrastructure with JPYC’s stablecoin ecosystem to enable continuous trading, near-instant settlement, and automated daily interest calculations.
The products will target both institutional and retail investors seeking yen-denominated exposure to Bitcoin-backed yields. However, no launch date, yield structure, or distribution plans have been approved; the partners are still conducting a joint study on product design, regulation, and investor protection. The completed Siiibo acquisition adds an established online corporate bond platform that has supported over 40 companies and more than 100 bond issuances.
