Japanese bitcoin treasury company Metaplanet has launched a continuous bond issuance program called BitBonds, starting with four privately placed series worth about 200 million yen ($1.3 million), according to a CoinDesk report on the Aug. 13 disclosure.
The program gives Metaplanet a fixed-rate funding channel alongside common stock, equity-linked securities and preferred shares. That model is part of a wider shift in which bitcoin-focused companies are expanding corporate balance-sheet tools, as covered in Rhino Bitcoin Adds 500M SPLD Tokens to Balance Sheet While Keeping Bitcoin-Only Mission.
How BitBonds are structured
Metaplanet said the inaugural BitBond series are unsecured senior bonds that mature in roughly three years and carry annual interest rates of 4% to 4.3%. Solicitation began in late July and has now closed, according to the disclosure. Because repayment depends on Metaplanet’s overall creditworthiness rather than segregated collateral, the notes leave investors indirectly exposed to changes in the value of its bitcoin-heavy balance sheet. That backdrop comes as bitcoin investment products continue to attract capital, with Bitcoin Investors Pour $853 Million Into Spot ETFs as BlackRock’s IBIT Leads Weekly Inflows.
The unsecured and unrated structure also highlights why security and custody risk remain relevant for bitcoin-linked companies. Although BitBonds are a debt instrument rather than a direct bitcoin holding, their credit profile is tied to the company’s ability to manage digital assets safely. Recent reporting such as Bitcoin Cold Wallets Drain $70M in Attack That Never Touched Hardware, Galaxy Research Reveals shows how quickly operational failures can affect the broader bitcoin market conversation.
What to watch for bitcoin-backed corporate debt
Metaplanet described BitBonds as a core funding channel, with future issuance tied to market demand and funding needs. That makes the program a test case for whether publicly listed bitcoin treasury companies can diversify their liabilities without relying only on share sales or convertible notes.
The initial 200 million yen sale is small compared with some equity-linked raises, but the signal is in the structure. If demand for fixed-rate bitcoin-credit exposure remains consistent, other treasury companies may follow with similar debt programs, adding a new layer to how corporate bitcoin adoption is financed.
