bDollar Bonds (bBDO) are a named token within the bDollar Protocol, an algorithmic multi-peg stablecoin running on Binance Smart Chain. They can be bought with BDO when BDO trades below its peg, removing BDO from circulation, and holders can redeem them for BDO when the Treasury has a positive BDO balance. bBDO does not have an expiration date.
