RedeemerTag

class cometa.witness_set.redeemer_tag.RedeemerTag(value)

Bases: IntEnum

The redeemer tags act as an enumeration to signify the purpose or context of the redeemer in a transaction.

When a Plutus script is executed, the specific action type related to the redeemer can be identified using these tags, allowing the script to respond appropriately.

SPEND = 0

Indicates the redeemer is associated with a spending script.

A spending script validates the spending of a UTXO. A UTXO can have either a public key address or a script address. To spend a UTXO with a script address, the script whose hash matches the script address must be included in the transaction (either directly, or as a reference script), and is executed to validate it.

MINT = 1

Indicates the redeemer is associated with a minting script.

Minting scripts, sometimes also referred to as minting policies, are used to approve or reject minting of new assets. In Cardano, we can uniquely identify an asset by its CurrencySymbol and TokenName.

CERTIFYING = 2

Indicates the redeemer is associated with a certifying script.

A certifying script can validate a number of certificate-related transactions, such as: registering a staking credential, de-registering a staking credential, and delegating a staking credential to a particular delegatee.

REWARD = 3

Indicates the redeemer is associated with a rewarding script.

A staking credential can contain either a public key hash or a script hash. To withdraw rewards from a reward account corresponding to a staking credential that contains a script hash, the script with that particular hash must be included in the transaction.

VOTING = 4

Indicates the redeemer is associated with a voting script.

A voting script validates votes cast by a Delegated Representative (DRep) or a constitutional committee member (CCM) in a transaction.

PROPOSING = 5

Indicates the redeemer is associated with a proposing script.

A proposing script, also known as constitution script or guardrail script, validates two kinds of governance actions: parameter change actions and treasury withdrawals actions.
