Why My Frontend Shows Wrong Balances

What This Error Actually Is

Frontend balance display errors occur when dApp interfaces show incorrect token or ETH balances due to caching issues, decimal conversion errors, stale data, or incorrect contract queries.

Why This Commonly Happens

Decimal conversion mistakes are common when displaying token balances. ERC20 tokens use different decimal places, and failing to account for this creates display errors showing values that are orders of magnitude incorrect.

What It Does Not Mean (Common Misinterpretations)

Wrong balance displays don't indicate that actual on-chain balances are incorrect. The blockchain state is accurate; the issue is in how the frontend queries, processes, or displays that data.

How This Type of Issue Is Typically Analyzed

Comparing frontend displayed values with direct blockchain queries reveals discrepancies. Checking decimal handling, caching logic, and data refresh mechanisms identifies the source of incorrect displays.

Common Risk Areas or Oversights

Cached balance data that doesn't refresh after transactions creates stale displays. Incorrect decimal conversion or missing decimals() calls cause balances to display with wrong magnitudes.
