TBCD is created to be worth slightly less than $1 when XOR is far lower than the current price point on the token bonding curve, reducing sell pressure to XOR when the price of XOR is low
TBCD (Token Bonding Curve Dollar) is convertible to XOR, as a reserve asset of the SORA token bonding curve, while also being worth $1 because the token bonding curve always treats TBCD as having a value of $1 USD.
TBCD can only be created and allocated by on-chain governance, which means that XOR token holders decide the supply
