-snip- and was used to create a time-locked address.
This is the only clue that you left in your post.
To create the redeem script of a "
Time-Locked Address", the owner should be able to export that unused address' public key.
Given that, it can't be a custodial wallet or exchange where pubKeys cannot be exported.
But that's where your search ends since there's no available data that can identify the origin of the wallet that generated its private key.
Services that do that are using "
educated guesswork" at best, based from heuristics that could link addresses together that may point to a known address of a platform.
That method can't be used without any transaction history.
