💸 LenderPool Types

Fixed Pool

Features of a fixed pool include:

• Locking Period: a timeframe for which deposits are held in a pool until their end date.
• Deposit Window: deposits are only allowed within a specified timeframe, after which the pool will be closed to any additional funding.
• Fixed APR and Bonus Rate: non-variable annual percentage rate (APR) and bonus rate set by the pool administrator throughout the deposit period.

Flexible Pool

Features of a flexible pool include:

• Locking Period
  • Base pool:
    • No locking period
    • Lenders can withdraw their funds once the pool reaches its end date regardless of the time they made the deposit
  • Dynamic pool:
    • Locking period is optional
    • If a lender decides to set a locking period for their deposit, they can select a duration that has a min of 3 months and a max of 12 months, and the rewards are calculated based on the duration and the bonding curve model
• No Deposit Window: flexible pools do not have any restrictions on the timeframe within which lenders can make deposits.
• Dynamic APR and Bonus Rate: variable annual percentage rate (APR) and bonus rate based on a bonding curve model.
