Get Transaction Count
This tool retrieves the number of transactions sent from a specific address (also known as the nonce). it uses the eth gettransactioncount endpoint to return the transaction count for an address at a specified block tag (latest, pending, earliest, or a hex block number), which is essential for determining the nonce for subsequent transactions.
Why this helps
Looking up a wallet manually adds another small task to an already busy contact review.
- Adds a transaction count lookup to contact review
- Lets your instruction specify a block tag such as latest or pending
- Reports when the contact record lacks a wallet address
