What Determines If a Transaction Is ‘Valid’ for Entry into the Mempool?

A transaction must satisfy several criteria to be considered valid and enter the mempool. These include having a correct format, being digitally signed by the owner of the funds, spending existing and unspent outputs (UTXOs), and not violating any other network consensus rules.

If a transaction fails any of these checks, it is immediately rejected by the node.
