# Introduction
**Edge** empowers users in DeFi to earn stable, attractive returns by utilizing **cSigma’s institutional platform**. Through fully backed, fixed-interest loans to institutional borrowers, Edge offers users dependable yields and access to liquidity through shorter-term lending strategies. This approach is designed to offer more stability and outperformance compared to other leading DeFi platforms.
Built on cSigma’s **secure smart contracts** and **lending framework**, Edge aims to create a trusted environment where users can confidently invest.
*Currently, users can deposit stablecoins like USDT and USDC into Edge, receive LP tokens, stake these LP tokens, and immediately start earning consistent returns*

* **Edge Pools (ERC-4626)** – Asset-specific tokenized vaults where users deposit a single stablecoin (e.g., USDC or USDT) and receive an LP token representing their stake in that pool.
* **csUSD Vault (ERC-7575)** – Multi-asset tokenized vault where users deposit supported stablecoins (initially USDC and USDT) and receive csUSD, a single yield-bearing share token backed by multiple assets.
* **csLYD Vault (ERC-7575)** – Represents a new class of onchain strategy vaults where users deposit supported stablecoins (USDC, USDT, and others) and receive csLYD — a yield-bearing share token backed by actively managed onchain strategies executed by institutional-grade asset managers.
All three product lines operate on the same **cSigma** **institutional lending backend,** allocating funds to vetted institutional borrowers and onchain asset managers to generate yield. Users can choose the product that aligns with their preferences for asset exposure, diversification, and strategy type.
While **csUSD** focuses on a dynamic blend of **institutional, RWA and onchain yield**, **csLYD** extends the platform to only **onchain yield strategies**, enabling users to earn **DeFi-native returns** with institutional-level risk management.
| Feature | **Edge Pools** | **csUSD Vault** | **csLYD Vault** |
| ------------------ | ------------------------------------------- | ------------------------------------------------------------- | --------------------------------------------------------------- |
| **Vault Type** | ERC-4626 | ERC-7575 | ERC-7575 |
| **Asset Type** | Single stablecoin (USDC/USDT) | Multi-stablecoin (USDC + USDT) | Multi-stablecoin (USDC, USDT) |
| **Yield Source** | Institutional borrowers | Institutional + RWA lending + onchain Yield strategies. | Onchain yield strategies (DeFi, delta-neutral, liquidity, etc.) |
| **Exposure Type** | Single-asset | Diversified credit | Active onchain strategy |
| **Risk Profile** | Low (single borrower exposure) | Moderate (diversified borrowers) | Moderate (strategy-based) |
| **Ideal For** | Users seeking stable, asset-specific yields | Users seeking diversified institutional yield + onchain yield | Users seeking managed onchain yield strategies |
| **Token Received** | LP Token | csUSD | csLYD |
Edge Pools remain ideal for users who prefer single-asset exposure, while the csUSD Vault offers diversified exposure of RWA and onchain yield with a single share token.\
The csLYD Vault complements both by providing access to managed, onchain yield strategies within the same trusted institutional framework.
By maintaining all three products, **cSigma** **Edge** allows users to select the yield structure that best fits their goals — from stable institutional lending to diversified vault exposure and advanced onchain strategies — all within a unified and intuitive interface for deposits, withdrawals, and tracking returns.
**Edge** is a decentralized application (dApp) by cSigma Finance that bridges institutional lending and DeFi, allowing users to earn real, sustainable yields. Built on cSigma’s secure smart contract infrastructure, Edge provides two parallel ways for users to participate in its lending ecosystem:
1. **Edge Pools (ERC-4626)** – Asset-specific tokenized vaults where users deposit a single stablecoin (e.g., USDC or USDT) and receive an LP token representing their stake in that pool.
2. **csUSD Vault (ERC-7575)** – *Launching in the first week of September 2025*, this is a multi-asset tokenized vault where users deposit supported stablecoins (initially USDC and USDT) and receive **csUSD**, a single yield-bearing share token backed by multiple assets.
Both product lines operate on the same institutional lending backend, allocating funds to vetted institutional borrowers to generate yield. Users can choose the product that aligns with their preferences for asset exposure and diversification.

### Why We Are Launching csUSD
While Edge Pools have successfully given users access to institutional lending yields, each pool operates independently. This means users who want exposure to multiple stablecoins must deposit into multiple pools, manage separate LP tokens, and track yields for each one.
**csUSD** solves this problem by:
* **Simplifying portfolio management** – One deposit, one token, diversified exposure.
* **Reducing user overhead** – No need to manage multiple LP tokens or rebalance across pools.
* **Providing built-in diversification** – Backed by multiple stablecoins, reducing single-asset risk.
* **Streamlining yield** – All yield is reflected in the value of csUSD without juggling multiple positions.

### Key Differences Between Edge Pools and csUSD Vault
| Feature | **Edge Pools (ERC-4626)** | **csUSD Vault (ERC-7575)** |
| ----------------------------- | ----------------------------------------- | --------------------------------------------- |
| **Token Type** | Pool-specific LP token | Unified csUSD share token |
| **Asset Backing** | Single asset per pool | Multiple stablecoins |
| **Diversification** | No – exposure to one stablecoin | Yes – diversified across multiple stablecoins |
| **User Deposits** | Directly into chosen pool | Into unified multi-asset vault |
| **Withdrawals / Redemptions** | Burn LP tokens for underlying asset | Redeem csUSD for USDC or USDT |
| **Oracle** | Pool-specific price feed and AUM tracking | Multi-asset oracle with per-token pricing |
| **Cross-Chain Support** | Yes | Yes |
| **Standard** | ERC-4626 (Tokenized Vault Standard) | ERC-7575 (Multi-Asset Vault Standard) |
***
### Why Both Products Exist
Edge Pools remain ideal for users who prefer single-asset exposure, while the csUSD Vault offers diversified exposure with a single share token. By maintaining both products, Edge allows users to select the yield strategy and asset structure that best meets their needs, all from the same platform.
Both options are accessible directly in the Edge dApp, with a unified, intuitive interface for deposits, withdrawals/redemptions, and tracking returns.
