Overview

The Yieldex architecture is divided into three key modules:

1. Data Collection Module

2. Decision Making / Analytics Module

3. On-chain Interaction Module

Data Collection Module

• Collects information about current APY/APR, TVL, availability, etc. from the protocols in different networks.

• Store results in a database and periodically update (e.g., every 10 minutes).

Decision Making (Analytics) Module

• Receives grouped data on returns

• Calculates whether it makes financial sense to transfer funds: for example, from AAVE USDT (APY ~5%) to Compound USDT (APY ~8%).

• Generates a "call to action" — a structure that specifies the network, protocol, token (USDT, USDC, etc.), quantity, and target return.

On-chain Interaction Module

• Accepts "call to action" and initiates transactions on users' smart wallets

• Uses ERC-4337 mechanics to securely aggregate transactions within a single "UserOperation".

• Sets signing parameters, and uses session keys for limited actions (deposit/withdraw/borrow/repay).
