Introduction
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:
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) – 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.

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.
