Example use cases
Maximize yield for idle wallet funds
“I have crypto sitting in my wallet at 0x1234abcd...ef — can you find the single best vault I should deposit into right now to maximize my yield?”
DeFi portfolio rebalancing decision
“I'm rebalancing my DeFi portfolio for wallet 0xdeadbeef...99 — what's the top vault recommendation based on my current balances and current APYs?”

“For my wallet address 0xaabbccdd...11, check what the best vault opportunity is so I can decide whether to move my funds there for better returns.”
