# Configure Transaction Nonces

What a Stacks nonce is, and how to set it yourself when you send a Stacks transaction in Leather.

A nonce is a sequence number on each Stacks transaction from an account. The first transaction has nonce 0, the next 1, and so on. The network confirms an account's transactions in nonce order: a transaction with nonce 8 waits until the one with nonce 7 is confirmed.

Leather sets the next nonce for you. Change it only to fill a gap or to replace a pending transaction. See [Understand Pending Transactions](/transactions/pending-transactions.md).

## Edit the nonce

1. In the Stacks send form, click "Edit nonce".
2. Enter the nonce you want and click "Apply".
3. Continue with the send. The review screen shows the nonce.

The [Stacks Explorer](https://explorer.hiro.so/?chain=mainnet) shows the nonces of your past transactions.

Vault accounts do not offer "Edit nonce".
