# Contract Relationships

## Lender <-> MarketPlace

The Lender is related to the MarketPlace contract. Primarily, it relies on the MarketPlace for information about the available markets. MarketPlace contains a `markets` mapping that stores principal tokens for a given market.

## Redeemer <-> MarketPlace

Similar to the Lender, the Redeemer relies on the MarketPlace contract for information about markets.&#x20;

## Redeemer <-> Converter

The Redeemer relies on the Converter contract to convert redeemed assets to the underlying asset for a given market. Specifically, Pendle and Sense redeem to the compounding asset. As a convenience to users, we convert these assets on behalf of users via the Converter contract.
