# Super Layer

At the core of Superposition's architecture lies the Super Layer, a system that is more than the sum of it's parts. The Super Layer is the emergence of Super Assets, the Longtail Orderbook, Utility Mining and the core innovations of Superposition in a system. Here's an exploration into what the parts of the Super Layer do:

### Super Assets:

Super Assets are like regular tokens, such as USDC or ETH, but they allow us to pay yield when you use the chain. They go beyond regular yield bearing tokens that pay yield when you hold on to them, Super Assets also pay you yield when you use them.

#### Functionality

* **Active Yield:** Super Assets pay you yield for your action on-chain, for example sending a payment , purchasing an NFT or making a trade. 

{% hint style="info" %}
Any on-chain transaction qualifies for active yield. 
{% endhint %}

* **Passive Yield:** Super Assets can also pay you yield when you hold onto them, allowing for native on-chain yield.

### Longtail - The Superbook:

Longtail is the liquidity layer on Superposition that combines an AMM with a Cross Chain Order Book, allowing users to use both types of tools. Applications share liquidity and assets between themselves through longtail, which is planned to support various types of asset and facilitates spot orders, perpetuals, and other derivatives.

#### Advantages

* **Composable:** Built on Stylus for maximum efficiency
* **Built on Stylus:** Arbitrum Stylus provides the ability to run Rust applications on EVM
* **Advanced Tools:** Professional trading interface with full orderbook functionality
* **Spot/Perps:** Support for spot trading and perpetual contracts
* **DEX Liquidity API:** Easy integration for developers

### Cross Chain Orderbook (with Espresso) 

The next step for CLOBs - unifying trading liquidity and improving capital efficiency across chains. Built in collaboration with Espresso Systems, this provides:

* Instantaneous cross-chain liquidity
* Better intent-based bridging and solving
* Reduced fees for users and developers
* A highly liquid Cross Chain Intent Layer

### Super Vault

Deposit from any supported chain and immediately earn yield from various strategies and money markets. The Super Vault transforms idle deposits into a dual-yield engine, auto-farming blue-chip DeFi money markets while simultaneously market-making our cross-chain orderbook.

### Utility Mining:

Utility mining is a novel distribution strategy, that allows the Superposition chan and dApp developers on the Superposition chain to distirbute yield and tokens to users of the chain and the dApps. Utility mining allows for aligned incentives.
