bDollar ($BDO) is an algorithmic stablecoin running on Binance Smart Chain with completely decentralized on-chain governance.



bDollar is designed with an innovative solution that can adjust its supply deterministically to move the price of the token in the direction of a target price of $1 to bring programmability and interoperability to DeFi.



Inspired by Basis Cash and its predecessors, bDollar Protocol is a multi-token protocol that consists of three tokens: 

  • $BDO, the algorithmic stablecoin.

  • bDollar Shares, or $sBDO, which holders can claim BDO inflation when the network expands.

  • bDollar Bonds, or $bBDO, which can be purchased at a discount rate when the network is in contraction and can be redeemed for BDO when the network comes to its deflationary phase and price goes below $1.

Then how bDollar mechanisms works?



When $BDO trades below the $1 target price, token holders can purchase bDollar Bonds with an extra discount and Bonds will be burnt to reduce the circulating supply when users redeem bDollar with a 1:1 ratio. In case of redemption, an amount of $BDO will be minted to equal the bDollar Bonds that have been redeemed. Important to note is that Bonds have no expiry after purchase.



When $BDO price is above the $1 peg, the token supply will have to expand to push it back down to 1$ and the contract will allow the redemption of the bDollar Bonds. When the price of bDollar continues trading above the $1 target price after bond redemption, the contract mints an appropriate amount of new $BDO and this will be distributed to the Boardroom Stakers.



It also has its unique algorithm: The epoch duration is 6 hours. The maximum rebase/expansion amount is 3%. It has no expiry for Bonds.



To participate in the protocol, you can visit the bDollar Banks dashboard, and select your preferred pool. It currently supports BUSD, DAI, CAKE and BFI.
