# Instant Lending and Repayments

## Borrow and Repay Eth Anytime

Instant over-collateralized lending allows users to borrow the assets they need at anytime. At the same time, interest will accrue based on the blocks, and users can also repay their borrowings at any time.

DEFED's Borrow and Repay are both based on a peer-to-pool lending protocol. All borrowing and repayments interact directly with the lending pool, powered by smart contracts, so there is no waiting and no matching time.\\

## What assets can be used for collaterals?

For risk control reasons, DEFED only accepts some assets as collateral in the early stages, and only supports lending requests for these assets.

List of assets:

ETH, WBTC, USDC.

In the future, with the growth of protocol, the list of supported assets will also change. Please stay tuned for updates to this document.\\

## Valuation of assets used as collateral

Like most DeFi protocols, DEFED uses an oracle machine to feed asset prices in order to ensure fairness, control risk and protect depositors.

Currently, DEFED uses the oracle machine service provided by Chainlink.The collateral valuation is part of the risk module.

The collateral valuation is part of the risk module, so as the risk module is improved, the relevant parts can be further optimized to reduce the system risk and provide a more accurate and timely reference for the collateral valuation.\\
