⚠️ Potential issue | 🟡 Minor

Add guard against undefined chain configuration.

If VAULTS[api.chain] is undefined (e.g., a new chain is added to exports but not to VAULTS), accessing .length throws a TypeError.

🛡️ Proposed fix 
   return async (api) => {
       const vaults = VAULTS[api.chain]
-      if (!vaults.length) return
+      if (!vaults?.length) return

In `@projects/travessia/index.js` around lines 18 - 19, The code currently assumes
VAULTS[api.chain] exists which can throw when undefined; update the logic around
the const vaults = VAULTS[api.chain] and the subsequent if check in
projects/travessia/index.js (the vaults variable) to first guard for
undefined/null (e.g., if (!vaults || !vaults.length) return) so the code returns
safely when the chain has no configuration; ensure you reference and update the
vaults variable and the existing if-check rather than only checking .length.

⚠️ Potential issue | 🟠 Major

Borrowed calculation can fail when liquidity[i] is null/undefined.

Line 36 checks underlyings[i] and totalAssets[i] but not liquidity[i]. When the balanceOf call fails (e.g., invalid underlying address), liquidity[i] will be null/undefined due to permitFailure: true. The subtraction totalAssets[i] - liquidity[i] will then produce NaN or throw a TypeError.

🐛 Proposed fix 
       vaults.forEach((_, i) => {
           if (!underlyings[i] || !totalAssets[i]) return
-          isBorrowed ? api.add(underlyings[i], totalAssets[i] - liquidity[i]) : api.add(underlyings[i], totalAssets[i])
+          if (isBorrowed) {
+              if (liquidity[i] == null) return
+              api.add(underlyings[i], totalAssets[i] - liquidity[i])
+          } else {
+              api.add(underlyings[i], totalAssets[i])
+          }
       })

In `@projects/travessia/index.js` around lines 35 - 38, The loop in vaults.forEach
uses liquidity[i] in a subtraction when isBorrowed is true but doesn’t guard
against liquidity being null/undefined; update the loop (vaults.forEach) to
check liquidity[i] before subtracting (e.g., if (isBorrowed && (liquidity[i] ==
null)) return/continue to skip this vault or treat missing liquidity as 0), and
only call api.add(underlyings[i], totalAssets[i] - liquidity[i]) when
liquidity[i] is a valid number; ensure you reference underlyings[i],
totalAssets[i], liquidity[i], isBorrowed, and api.add in the change so the
subtraction never produces NaN or throws.
