Nonce Checker
Use this nonce checker to query the latest and pending EVM account nonce from a live RPC endpoint for Ethereum, Base, Arbitrum, Optimism, or a custom network.
Enter an address to query live nonce values.
Example Usage
- Check whether a wallet has pending transactions stuck ahead of the mined nonce.
- Compare latest and pending nonce before sending a manual transaction.
- Query nonce state on Base, Arbitrum, Optimism, or a custom RPC URL.
Nonce Checker Explained
A nonce checker helps you understand the transaction sequence state of an EVM account. It queries both the latest mined nonce and the pending nonce from a live RPC endpoint, then shows the gap between them. That gap can reveal whether the account has queued or unconfirmed transactions that may affect the next usable nonce. This is helpful when you are debugging wallet behavior, replacing transactions, handling manual signing, or checking whether a stuck pending state exists. Because it runs in the browser and uses a standard JSON-RPC endpoint, it stays static-site compatible while still providing live chain data.
FAQ
What is an EVM nonce?
It is the transaction sequence number for an account, incremented each time that account sends a transaction.
Why compare latest and pending nonce?
The difference can show whether there are queued or unconfirmed transactions ahead of the latest mined state.
Do I need my own RPC URL?
No. You can use a preset network RPC or provide your own custom endpoint.
