Cross chain swap aggregators and triple fee complaints

April 6, 2026r/CryptoTechnology

In r/CryptoTechnology, explainers distinguish bridges, DEXs, and aggregators, while practitioners complain aggregators can stack fees and recommend checking routes then executing directly on the chosen bridge.

Bridge: Moves tokens from one blockchain to another. That's it.
DEX: Lets you swap tokens within the same chain. Uniswap, Curve, etc.
Aggregator:Checks multiple bridges and DEXs simultaneously and picks the route that gets you the best rate.
The architecture of using aggregators is user end up paying triple fee if bridging inside wallet or any protocol.
Bridge fee + aggregators fee + dapp fee.
