Is it possible to delete or transfer a contract?

Hi, I’d like to ‘throw away the keys’ to my NFT collection. Leaving it up for posterity but not allowing myself a back door in. Kind of like a time capsule.

Is there a way to remove my access to the SC? Delete it? Transfer to a new wallet and throw away the key?

Any suggestions for other ideas?

Thank you

Yes, you can use the renounceOwnership function on the smart contract.
