## Tranches

Each Lending Pool has one or more Tranche(s). The Liquidity Providers do not provide Liquidity directly to the Lending Pool, but via a Tranche. Each Tranche contract will do the accounting of the balances of its Liquidity Providers, while the Lending Pool will do the accounting of the balances of its Tranches. A Tranche is according the ERC4626 standard, with a certain ERC20 as underlying asset. The Tranche is not compliant with ERC4626 on the approval flow: the approval goes to the Lending Pool instead of the Tranche, the deposit() is called on the Tranche itself.

## Wrapped Tranches

A Wrapper of the Tranche contract is deployed for each Tranche. The Wrapper is fully compliant with ERC4626 and can be preferably used in integrations.
