ScriptPurpose

Each redemption in a transaction has a ScriptPurpose with the following 4 variants:

  • Minting
  • Spending
  • Rewarding
  • Certifying

ScriptPurpose::Rewarding and ScriptPurpose::Certifying are identical to StakingPurpose::Rewarding and StakingPurpose::Certifying respectively, but the use cases are different. StakingPurpose is used for switching between rewarding and certifying within a given staking script. ScriptPurpose is used to see what other scripts are being used in the same transaction (see tx.redeemers).
