Transaction Intents
Each transaction has a single transaction intent. Its transaction id is the hash of the transaction intent, and is typically encountered bech32-encoded starting with txid_....
Structure
For full details, see the transaction structure article, but to summarize, a transaction intent contains: * A transaction header, defining the notary and tip. * Its intent core, including its: * An intent header, capturing when it’s valid for * An optional message * Its transaction manifest * Zero or more subintents
Behaviour
Compared with subintents, the transaction intent is special: * Only the transaction intent is allowed to lock a non-contingent fee, and only the transaction intent defines the tip. * If a transaction execution fails after a fee is locked, then the transaction intent is recorded as a committed failure, and can never be committed again. Subintents by contrast can be committed zero or more times and still be committed successfully. * If a notary is marked as a signatory, the notary only counts as a signatory of the transaction intent.
