Nonce - What is this and optional use

The nonce is a transaction counter attached to an address. 

Some blockchains like Ethereum require you to use nonce to avoid double spending and replay attacks.

However, Tatum allows you to make transactions with these blockchains without the nonce. 

When not specified, the last known nonce value will be used by the Tatum engine.

Good to know

• Automatically calculating the nonce by the Tatum engine has a delay. 
• Customers with high transaction broadcast volume in a row (e.g., x1000) may want to consider manually applying nonce on their transactions.
