# AllBlue Ecosystem Overview

The AllBlue ecosystem consists of three core products: AllBlue V2, AllBlue V3, and AllBlue Stable.

Each product provides a different liquidity model while remaining connected within the broader AllBlue ecosystem through supported tokens and liquidity pools.

### Product Overview

| Product        | Liquidity Model        | Position     | Primary Role                                                   |
| -------------- | ---------------------- | ------------ | -------------------------------------------------------------- |
| AllBlue V2     | Constant Product AMM   | LP Token     | Pair-based liquidity and Swap                                  |
| AllBlue V3     | Concentrated Liquidity | Position NFT | Price-range-based liquidity and Swap                           |
| AllBlue Stable | Stable Token / Yield   | b-Token      | Stable token deposits, reward accounting, and b-Token issuance |

### AllBlue V2

AllBlue V2 is a Constant Product AMM protocol.

Liquidity providers supply two tokens to a Pair and receive LP Tokens representing their share of the liquidity.

V2 provides a simple and predictable Pair-based liquidity structure.

### AllBlue V3

AllBlue V3 is based on a Concentrated Liquidity model.

Liquidity providers can allocate liquidity within selected price ranges instead of across the entire price range, with each Position managed independently.

This structure allows liquidity to be concentrated around selected price ranges.

### AllBlue Stable

AllBlue Stable supports designated stable tokens and issues corresponding b-Tokens.

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

b-Tokens may be used as liquidity in supported AllBlue V2 Pairs and V3 Pools.

```

b-Tokens issued through AllBlue Stable may be used as liquidity in supported V2 and V3 markets.

Each protocol operates independently through its own smart contracts, while users can interact with supported products according to the functionality available within the AllBlue ecosystem.
