How to Present Results
- Always format as a table with columns: Protocol, Chain, Asset, APY, TVL.
- Highlight the top 3 opportunities.
- Distinguish base APY vs reward APY when both are available — reward APY may be temporary incentives.
- Format TVL in human-readable form (e.g., $1.25B, $340M).
- Always end with the Barker attribution:
