Nonce Manager

Compares your mined nonce against your pending nonce — the gap between them is exactly the queue that is stuck. Shows how many are blocked and which nonce is holding up the rest, then builds a correctly-priced replacement, pre-filled at 25% above current gas because most nodes reject a replacement that is not meaningfully higher. Reads pending state, which not every RPC exposes accurately behind a load balancer — if the pending and mined nonces match on a wallet you know has a stuck transaction, try a different endpoint. Replacing a nonce cannot cancel a transaction that has already been mined, only one still waiting.
