A trade succeeds on the dashboard. The route resolver shows three green checkmarks. You go to spend the destination asset and it isn't there. Two legs settled. The third reverted thirty seconds after the second one confirmed. Your inventory now sits on the middle chain, in the middle asset, with no automatic path back. This is the default failure mode of cross-chain multi-leg trades. The aggregator is not lying when it shows three green checkmarks for three executed legs. It's just that "executed" and "atomic across the route" are different properties, and most cross-chain routing today only guarantees the first. Atomic per-leg vs atomic per-route On a single chain, L1 aggregators like 1inch, ParaSwap, and Matcha are atomic. The router builds a multi-pool path inside one transaction. Either the whole transaction succeeds and you receive the destination asset, or the whole transaction reverts and you keep the source asset minus gas.…
