[Copilot]

Pull request overview

Updates the Explorer homepage stats to show metrics for all tokens returned by the subgraph (instead of hard-coding USDFC and FIL), aligning with issue #137.

Changes:

• Update the stats dashboard GraphQL query to fetch the full tokens list.
• Simplify useStatsDashboard to no longer require token address variables.
• Render “Total <token> Transacted” and “Total <token> Locked” cards by iterating over returned tokens.

apps/explorer/src/components/Home/Stats.tsx	Replaces fixed USDFC/FIL cards with dynamic cards generated from tokens.

• The tokens field is queried without pagination (first/skip) or an explicit first limit. For subgraph/The Graph style APIs this commonly defaults to 100 results, which can prevent the homepage from showing metrics for all known tokens as the PR intends. Consider adding a $first variable (with a sufficiently high default) or implementing pagination to fetch all tokens.

  query GetStatsDashboard {
    tokens {
      name
      symbol
      decimals
      totalOneTimePayment
      totalSettledAmount
      userFunds
      lockupCurrent
      lockupRate
      lockupLastSettledUntilEpoch
    }

Overall looks good to me! I have a couple of concerns -

1. Homepage may display unknown tokens, just not known ones. We could address this by either:
   • Adding a limit/filter in the graphql query, or
   • Restricting results to whitelisted token addresses on home page
2. When the query returns no tokens, ui will silently renders zero cards with just the section heading no fallback message. It would be good to handle this explicitly.

Homepage may display unknown tokens, just not known ones.

This is the whole point of the PR: Display all tokens in use, not just the ones the maintainers know about.

Good catch, but this will be prevented once other network metrics are back, like total FIL burned

That makes sense. My only concern is around scalability. Once we have more tokens (say 5+), this could result in quite a few cards on the homepage alongside the existing metrics.

Not an issue right now since we only have ~3 tokens, but something we might want to keep in mind (e.g. limiting tokens on homepage and moving to table view instead).

Agreed, this will be a good problem to have, and I vote for fixing it then 🥳
