Problem Statement

Condition to trigger collateral Swap:Price change(e.g. DAI price is less than 0.99)Interest Rate change of the pool(Daily Interest change is more than 1%)Once order is picked up by solver and executed, show a link to blockscout explorer on console.Then execute switch collateral from token A to token B on the following supported lending protocol:Aave v3Euler

Solution

To call order automatically → Cow Programmatic order. Their solvers keep calling the getTradeableOrder function, which trigger condition is defined periodically.To execute collateral swap: CowSwap order + Pre/HookTo fetch the current price data → Pyth OracleTo import daily interest change of the lending pool → Brevis(Fetch interest rate data from tx event and calculate interest rate difference on their zk coprocessor, then update value in smart contract)
