Let’s say I deploy two canister, representing two different tokens, on IC. Let’s assume token X on subnet A and token Y on subnet B. Now if I need to trade token X for token Y are these transactions atomic i.e. is atomicity guaranteed by IC or do I need to build that into my Dapp canister? Thanks in advance.

On the IC replicated calls on different canisters (as needed for your scenario) are not atomic, so you would need to implement atomic transactions at the canister level.

Thought as much. Thanks for the confirmation.
