In this commit, we rework how
publishTransaction
works in order to correctly handle removing invalid transactions from the wallet's unconfirmed transaction store. This is crucial as otherwise, invalid transactions can remain within the wallet and be used for further transactions, causing a chain of inaccurate transactions.publishTransaction
will now only return an error if the transaction fails to be broadcast and it has not been previously seen in the mempool/chain. This is intended in order to provide an easier API to callers. Any other errors when broadcasting the transaction will cause it to be removed from the wallet's unconfirmed transaction store to ensure it maintains an accurate view of the chain.
