The PoolTogether code base breaks out every component into a composable system of contracts that all work together to create a permissionless hyperstructure for prize savings:

• Draw Manager - keeps the prize machine ticking over everyday with a series of auctions
• Liquidator - swap yield for prize tokens
• Prize Claimer - claim prizes on behalf of depositors
• Prize Pool - the core of the prize system
• Prize Vault - deposit and win prizes
• Twab Controller - track weighted-average balances of depositors
• Twab Delegator - delegate a portion of deposits to other accounts
• Twab Rewards - permissionlessly create a stream of token rewards to depositors
• Vault Booster - boost the prize power of a vault
