# Lending

3A protocol offers **interest-free loans** that support a wide variety of collateral tokens whitelisted by a data-driven risk model. Collateral is any token that a borrower provides to take out a loan, acting as a security for the debt. 

Currently, 3A only supports crypto-assets, but later on will expand to the tokenized Real-World-Assets. 

Instead of selling their tokens to have liquid funds, users or protocols can use the 3A platform to lock up the tokens in a Vault and borrow against them to withdraw EURO3.

**There is no recurring interest, no minimum debt, or deadline to repay the debt** as long as there is a sufficient amount of collateral.
