# Time Based Collateral Pool The time based collateral pool (TBCP) enables assets from multiple accounts to be collectively pooled for mutual collateral reservations. Third parties may configure and deploy instances of the TBCP contract as required for intended credit operations. Accounts provide assets to a collateral pool and receive pool units proportional to its total balance. Pool units are associated with each account. To ensure predictable and efficient pool withdrawals, collateral is subject to time-based exit periods. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
