The Ethereum Virtual Machine is the ground truth under everything else: every protocol, every token, every position is, in the end, contract calls and balances on the machine, and the plans that hold up are the ones built directly against it.
This protocol carries the machine's own verbs. Balances read at execution time, transfers of any token or the native asset, approvals granted exactly as wide or as narrow as a plan needs and revoked the moment they are no longer needed, ether wrapped and unwrapped when a route demands it, and arbitrary values staged for downstream steps to consume. Nothing here belongs to any one protocol, which is why every plan ends up using it.
The small verbs are where the real hygiene lives. An allowance that revokes itself the moment the strategy that needed it finishes. A balance checked in the same transaction that spends it. Dust swept, the gas asset topped up, a wrap done at the exact block a route requires it. These are the steps nobody enjoys doing by hand and everybody pays for skipping.
Every plug bottoms out in these operations. Having them as first-class, condition-driven steps is what makes everything above them composable.
