Has the bpEUR been running?

  • bpEUR — the first Multi-Peg seigniorage tokens under bDollar protocol pegged on a major fiat currency, EUR — started printing money at Multi-Pegs site from Epoch #383 (Wed 07 Apr 2021 00:00:00 AM UTC+0) with the current TVL 8.8 M+.

bpJPY is the first Multi-peg seigniorage tokens voted by our community. Below is the explanation of how bpJPY mechanisms works:

bpJPY trades below the ¥1 target price

When the bpJPY price is below the target price ¥1, token holders can purchase Coupons and bpJPY will be burnt to reduce the circulating supply when users redeem bpJPY tokens with a 1:1 ratio.

In case of redemption, an amount of bpJPY will be minted with premium with the Coupons that have been redeemed.

bpJPY trades above the ¥1 target price

When bpJPY price is above the ¥1 peg, the token supply will have to expand to push it back down to the target price ¥1 and the contract will allow the redemption of the Coupons.

When the price of bpJPY continues trading above the ¥1 target price after Coupons redemption, the contract mints an appropriate amount of new bpJPY and this will be distributed to the Boardroom Stakers.

Peg bpJPY

The TWAP of bpJPY will be subsequently calculated from 2 liquidity pools: rate of bpJPY over BNB and rate of bpJPY over BDO.

To get the final rate of bpJPY over JPY, we use price feeds of JPY/USD and BNB/USD powered by ChainLink oracle services to ensure maximal robustness and efficiency. The rate of BDO/USD will be the latest TWAP of BDO (assumed that BUSD is always 1 dollar).

Expansion phase happens when bpJPY TWAP above ¥1 in an Epoch with an example scenario:
