The Refund Action

Where registrations gone wrong are fixed

Note: The refund action code can be found here (Chialisp).

This action is very similar to the CATalog refund action, except that the pricing puzzle might either be a 'normal' or 'expiry auction' one. A precommit coin can be clawed back in the following cases:

• The CAT maker puzzle hash has changed

• The payment CAT amount is wrong

• The pricing puzzle in used has changed

• The handle has already been registered (and is still valid - i.e., has not expired)

The action also creates a puzzle announcement that can be asserted to ensure the dApp singleton is running the right action with the right parameters. For the refund action, the announcement prefix, $ , is concatenated to the precommit coin's full puzzle hash.
