# Decision Making

Determine the profitability of moving funds from one network to another.

1. Calculates yield difference (for example, 8% on one protocol vs 5% on another).
2. Evaluates gas costs and slippage (if token swaps are needed).
3. If the benefit exceeds a set threshold (for example, 0.5-1% APR), form a transaction for the On-chain Interaction Module.
