Universal Lending Pool

Perpetual/Floating Rate

A universal lending pool is a vault<-> (isolated lending pool)s architecture that accepts any set of collateral/credit conditions, such as illiquid tokens or NFTs or a certain credit criterion(assuming a composable identity layer). See the diagram in the Borrowing from the pool below.

A RAMMLend's vault could host multiple lending pools where its collateral is either a singleton or a combination of collaterals. A lending pool will be supplied/withdrawn by the vault when managers issue or redeem longZCB.

Adding a new pool

A new lending pool can be added to the vault by anyone. The following information needs to a provided either through the UI or contract calls. More details in parameter details
