# Roles in AlphBanx

### Borrower

* Deposits ALPH as collateral to mint ABD
* Chooses interest rate tier when borrowing
* Must maintain CR ≥ 200% or face liquidation
* Can repay loan at any time to reclaim collateral
* May have their vault repaid (redeemed) by other users if ABD is redeemed for ALPH

In a redemption event, borrowers with the lowest interest rate loans are prioritized. If your vault is selected for redemption, a portion of your collateral is used to repay ABD burned by the redeemer, but your total value remains unchanged.

### Earn Pool Participant (Stability Provider)

* Deposits ABD into auction pools (5%, 10%, 15%, 20%)
* Earns borrowing fees and discounted collateral from liquidations
* Passively contributes to system stability

### Liquidator (Triggering Role)

* Anyone can initiate liquidation when CR < 200%
* Triggers auctions to protect the protocol
* Does not need to hold any tokens

### ABX Staker

* Stakes ABX tokens to earn protocol fees
* Shares fees from minting, borrowing, redemptions, and liquidations
* Aligned with long-term protocol health
