# 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.

* Triggers auctions to protect the protocol
* Does not need to hold any tokens

### ABX Staker
