Transaction Nonce

A transaction nonce is a unique, sequential number included in every transaction sent from a specific address to prevent replay attacks and ensure ordered execution. Each time a user sends a transaction, the nonce must be exactly one greater than the previous one, ensuring that transactions are processed in the order they were intended.

If a user submits a transaction with an incorrect nonce, the network will reject it, preventing potential confusion or double-spending of collateral. In automated trading environments, managing the nonce correctly is essential to ensure that trades are executed in the correct sequence, especially during periods of high market volatility.

It is a simple yet vital mechanism for maintaining the sequential integrity of a user's activity on the blockchain.
