Our verdict on Promethium
Promethium may interest Arbitrum users looking for a tool to manage lending deposits and loans across markets. Its stated focus on rebalancing and refinancing is useful in principle, but key details—including supported assets, fees, app availability and audit status—are not established. Verify the app and its terms before connecting a wallet or approving tokens; without those details, it is difficult to assess whether the optimizer is suitable for your funds.
