WalletBrief

WalletBrief is a live search-and-revoke app for Monad. Paste any address to see current MON and WMON balances, transaction count, latest block, and ERC-20 approvals indexed through HyperSync. If the connected wallet owns an active approval, WalletBrief simulates approve(spender, 0) before asking for a signature. I built it because token permissions can outlive the dapps that requested them. Finding and revoking them still means explorer tabs, contract addresses, and guesswork. The public app is read-only by default and never holds a signing key. The repo also includes a verified mainnet BatchExecutor proof. I learned that approval discovery needs both indexed events and live allowance checks: RPC-by-RPC scanning is too slow, while event history alone can be stale.
