# Overview

AllBlue Stable is a stable token protocol that supports deposits of designated stable tokens and issues corresponding b-Tokens.

Supported underlying tokens can interact with external DeFi protocols, while related reward changes are reflected through AllBlue Stable's accounting structure.

AllBlue Stable operates on **Avalanche C-Chain** and connects stable token deposits with other parts of the AllBlue ecosystem.

### Key Features

* Supports designated stable tokens
* Issues corresponding b-Tokens
* Integrates with external DeFi protocols
* Reflects external protocol rewards through the AllBlue Stable accounting structure
* Supports redemption from b-Tokens back to the underlying tokens
* Enables supported b-Tokens to be used in AllBlue V2 and V3 liquidity pools

### Supported Tokens

| Underlying Token | b-Token |
| ---------------- | ------- |
| USDt             | bUSDT   |
| USDC             | bUSDC   |
| AUSD             | bAUSD   |

### Role in the AllBlue Ecosystem

b-Tokens issued through AllBlue Stable may be used in supported AllBlue V2 Pairs and AllBlue V3 Pools.

This allows stable token deposits to interact with the broader AllBlue liquidity ecosystem while maintaining a separate Stable protocol structure.
