Stacks launches first institutional Bitcoin bond offering 3% BTC yield without losing custody.

Stacks introduced the Genesis Bond on September 10, allowing four institutions to lock about 250 BTC for six months and earn roughly 3% annual yield paid weekly in BTC. The yield comes from Stacks miners via the Proof-of-Transfer mechanism, not lending, while the BTC remains on Bitcoin's base layer, ensuring full custody. Participants also hold STX tokens worth about 5% of their BTC position, which adds exposure to a second asset. A second bonding period is planned for October 2026 with broader access expected in the future.

Stacks' STX token is trading at Rp5,461 with a notable 11.95% gain in the last day as of September 19, 2026, 21:51 WIB on Pluang. This surge in STX price coincides with the launch of the Genesis Bond, which offers institutional investors a new way to earn yield on Bitcoin holdings. Despite strong selling activity at 83%, the token's market cap stands at Rp10.01 trillion, reflecting significant investor interest in Stacks' innovative Proof-of-Transfer staking program.
