About Valora Protocol

Introduction

The Valora (Decentralized Stablecoin) protocol is a production-ready, over-collateralized, algorithmic stablecoin protocol designed to maintain a soft peg of 1 DSC = 1 USD. The system is inspired by MakerDAO's DAI but built from scratch with modern Solidity practices and comprehensive testing.

System Overview

The DSC system allows users to:

Deposit Collateral

Deposit approved collateral tokens (WETH, WBTC)

Mint DSC

Mint DSC stablecoins against your collateral

Maintain Health

Keep a healthy collateralization ratio (โ‰ฅ200%)

Redeem Collateral

Burn DSC tokens to reclaim your collateral

Participate in Liquidations

Help maintain system health and earn a 10% bonus

Health Factor & Liquidations

Health Factor Calculation

The health factor determines the safety of a user's position:

healthFactor = (collateralValueUSD ร— 50%) รท totalDscMinted

Health Factor Interpretation:

โœ…
> 1.0

Healthy position, cannot be liquidated

โš ๏ธ
= 1.0

At liquidation threshold, risky position

โŒ
< 1.0

Unhealthy position, can be liquidated

๐ŸŒŸ
โˆž

No debt, perfect health

Liquidation Process

When a position becomes undercollateralized (health factor < 1.0):

1
Liquidators identify

Users with health factors below 1.0

2
Liquidators provide DSC

Cover some/all of the debt position

3
Receive collateral + 10% bonus

Economic incentive to maintain system health

4
Position health improves

User's health factor increases after liquidation

5
System remains fully collateralized

Protocol health is maintained through liquidations
