- Find which principal is tied to app 1
I think you cannot for good reasons (keywords no tracking, privacy and anonymous).
Two dapps though can share the same principal if alternative origins are used but I would personally say it’s unlickely that this would happen with NNS dapp and another dapp on the app subnet.
- Interact with ckBTC tied to app 1 -
icrc1_transfer
for instance
For the above reason, I would say you cannot too. The from
of an ICRC-1 transaction is the caller of the function icrc1_transfer
- i.e. the principal used in the dapp that calls the function.
Does it answer your questions?
