Inspired by Basis and its predecessors (Empty Set Dollar and bDollar), Midas Dollar is a multi-token protocol that consists of three tokens: MDO (the algorithmic stablecoin), Midas Dollar Shares (or MDS, which holders can claim MDO inflation when the network expands), and Midas Dollar Bonds (or MDB, which can be purchased at 1:1 rate when the network is in contraction and can be redeemed with premium for MDO the network returns to its inflationary state, above the $1 peg).
