The 3DAO is where the 3omb treasury builds liquidity. The purpose behind the 3DAO/Treasury is for the protocol to own its own liquidity. Protocol-owned liquidity helps 3omb not rely solely on the community to maintain its peg to FTM.
How does the treasury help the 3omb peg?
The treasury helps the 3omb peg by buying back 3omb in the event that the price of one 3omb falls below the price of one FTM. The treasury will allocate a certain percentage of funds to buy back 3omb one epoch after 3omb falls "below peg".
The treasury will not instantly bring 3omb back above peg. It buys 3omb slowly over time.
