⚠️ Potential issue | 🟠 Major

Avoid using partial owner lists when pagination is truncated.

Line 17 stops pagination with break, but Line 49 still uses partial solOwners. This can silently undercount TVL whenever MAX_PAGES is hit. Prefer cached full data when fullFetchCompleted is false (fallback to partial only if cache is unavailable).

Proposed fix 
 async function tvl() {
     let solOwners;
     try {
-        const result = await fetchAllVaults();
-        solOwners = result.solOwners;
-        if (result.fullFetchCompleted) {
-            await setCache(CACHE_KEY, "solana", solOwners);
-        }
+        const result = await fetchAllVaults();
+        if (result.fullFetchCompleted) {
+            solOwners = result.solOwners;
+            await setCache(CACHE_KEY, "solana", solOwners);
+        } else {
+            const cached = await getCache(CACHE_KEY, "solana");
+            solOwners = Array.isArray(cached) && cached.length ? cached : result.solOwners;
+        }
     } catch (e) {
         console.error("anoncoin: API fetch failed, falling back to cache", e.message);
         const cached = await getCache(CACHE_KEY, "solana");
         solOwners = Array.isArray(cached) ? cached : [];
     }

     return sumTokens2({ solOwners });
 }

In `@projects/anoncoin/index.js` around lines 16 - 20, The loop truncates
pagination when page > MAX_PAGES but then proceeds to use the partial solOwners
list, which can undercount TVL; modify the pagination/aggregation logic (around
hasMore, page, MAX_PAGES) so that when you hit the MAX_PAGES cutoff you set
fullFetchCompleted = false (or a similar flag) and do not use the partial
solOwners for final TVL calculations; instead attempt to load and use a cached
full result (fallback to the partial solOwners only if no cache is available),
and ensure any code that consumes solOwners checks fullFetchCompleted before
relying on it.
