### Describe the bug <img width="1630" height="627" alt="Image" src="https://github.com/user-attachments/assets/8ba6f939-be21-427a-9b67-813d20b6dd21" /> - When testing multiple wallets by adding another solana wallet on https://github.com/hummingbot/condor , observed that balance return 0 - One of the solana wallets has 0 balance which i think is where its fetching it - Check hummingbot-api gateway route - POST /gateway/add-wallet does not allow to add wallet as non-default ### Steps to reproduce bug 1. Add two wallets on same chain then run balance command (either one of them has 0 balance) 2. Observed that when checking balances, the most recently added wallet is automatically set as the default.
