# Puzzle Lend intro

Puzzle Lend is a decentralized protocol for lending and borrowing crypto.

**Suppliers** who provide assets receive passive income from the interest paid by borrowers.

**Borrowers** can obtain assets without selling the assets they have. For example, if someone holds WAVES, they can use it as collateral to borrow XTN which they can then use to participate in the IDO of a new promising token.

Puzzle Lend is built on the Waves blockchain which provides fast transactions and extremely low network fees — just a few cents per transaction.

## Isolated market model

The core concept of Puzzle Lend is isolated markets.

On a unitary market, a user can borrow any asset providing any other asset as collateral. That's why a single troubled asset can bring the whole market to a deadlock.

In contrast, the isolated market model enables more accurate risk management. Small-cap and volatile assets are placed in separate markets and do not impact the TVL of the main market with low-risk tokens.
