My token policy script is:

all: 
    [
        {
           invalidAfter: 40951072
        },
        {
           pubKey: "36ed345d252a242ad67072db79e5736866fa58ebe3fd782739208ef6"
        }
    ]

Since the slot already passes it looks like I can't burn tokens by cardano-cli 'mint' anymore. The error I get is:

Command failed: transaction submit Error: Error while submitting tx: ShelleyTxValidationError ShelleyBasedEraAlonzo (ApplyTxError [UtxowFailure (WrappedShelleyEraFailure (ScriptWitnessNotValidatingUTXOW (fromList [ScriptHash "6c6d152385ada4cc7606a31090ac37ac267b0b5e2e37ecaf6b47d146"])))])

I wonder is there any other 'best practice' to burn the token?

As Isaac stated, transaction with this policy is not possible anymore. But that does not mean it is not possible to publicly make assets unavailable. There is a great post on the Cardano form that goes in-depth on different types of burning methods [1]. Note that these tokens send to such addresses still exists but can't be transferred anymore by anyone.

You could send it to a wallet you control then destroy any record of your credentials :)

    It does not answer the case since I need to 'destroy' them publically. So anyone could be sure that it was burned.

  • It's impossible to get the policy script to validate since the validity interval has passed. There is actually no way to burn the token because Cardano was designed that way. Take a video of yourself transferring it to a hardware wallet then smashing it with a hammer :)
