PR checklist

For every PR, make sure that these statements are true:

• Includes only changes relevant to the original ticket. Significant refactoring needs to be separated.
• Doesn't contain type casts and non-null assertions.
• Doesn't add @ts-ignore.
• Doesn't disable lints.
• Doesn't use useState just for computation - use plain variables instead.
• Splits components into pure components that don't depend on external state or hooks.
• Avoid embedding components within other components
• Doesn't propagate optional values without good reason, doesn't mark property values as optional if that doesn't represent reality.
• Doesn't duplicate existing code.
• Parses out-of-domain data - this includes user input, API respones, on-chain data etc.
• Doesn't contain commented out code.
• Doesn't contain skipped or empty tests.
• If this PR adds/updates any feature, it adds/updates its test script

Subjective - at the discretion of the reviewers

• Does things as simply as possible, but not simpler.
• Doesn't reinvent the wheel or create premature abstractions.

@bhargavaparoksham works for explorer and manager, but when I connect to sepolia on builder, it doesn't load. I just get a blank screen.
