+;; Title: CCD002 Treasury
+;; Version: 3.0.0
+;; Summary: A treasury contract that can manage STX, SIP-009 NFTs, and SIP-010 FTs.
+;; Description: An extension contract that holds assets on behalf of the DAO.
+;; SIP-009 and SIP-010 assets must be allowed before they are supported.
+;; Deposits can be made by anyone either by transferring to the contract or
+;; using a deposit function below.
+;; Withdrawals are restricted to the DAO through either extensions or proposals.
+;; Stacking is enabled through PoX.
