# MINT - Extended Minting Transaction
|
|
|
|
Subsequent minting transactions of `additional_token_quantity` can be performed by spending the "minting baton" UTXO in a special MINT transaction, described here.
|
|
Note that this could be done by someone other than the [GENESIS](/protocol/slp/genesis) issuer, if the baton minting authority had been passed to another address.
|
|
|
|
As with GENESIS, the MINT allows to end the baton, or further pass on the baton to future mint operations: if `mint_baton_vout` is empty or refers to a nonexistent vout, the transaction is valid but the baton is lost.
|
|
This makes it possible to prove end-of-minting capabilities for a token even after several minting events (it is impossible to duplicate this baton as that would require double-spending the transaction output associated with the baton).
|
|
|
|
**Transaction inputs**: Any number of inputs or content of inputs, in any order, but with required presence of a 'baton' input (see [Consensus Rules](/protocol/slp#consensus-rules)).
|
|
|
|
**Transaction outputs**:
|
|
|
|
| v<sub>out</sub> | ScriptPubKey ("Address") | BCH amount | Implied token amount (base units) |
