BLUE Protocol is a decentralized reserve currency system built on BNB Chain, forked from Olympus DAO. The protocol maintains a treasury-backed reserve currency called BLUE, where each token is backed by a diversified treasury of reserve assets including BOOK tokens, BUD stablecoin, BNB, and liquidity pool tokens.

The protocol operates through a rebasing mechanism that provides staking rewards to participants. Users who stake BLUE tokens receive sBLUE, which automatically rebases every 4 hours at a rate of 0.286% per epoch, targeting an annual percentage yield of 50,000%. The protocol features six rebases daily, with rewards auto-compounding without requiring user action.
