[Bug] Watched accounts input checking; Invalid account crashes webapp

[0byt]

Watched Accounts: By using hex address format and typing in something like 0x01 the webapp will recognize those small hex strings as valid addresses and allows them to be added as watched accounts.

after adding those actually invalid addresses the portfolio tab freaks out due to parsing invalid addresses to fetch for staking information.

Expected behavior: Need to check for valid address before adding

Furthermore this blocks the whole staking feature to disallow for staking fresh funds. Not only for the invalid accounts as they are only added as watched accounts but for all accounts in general. Thats the error I get:
