A bridge: a single path
A bridge moves value from one chain to another through its own mechanism, whether that is locking and minting, holding reserves on both ends, or a solver filling the destination. Each bridge has its own supported routes, fees, speed, and trust model. Used directly, you are committing to that one bridge's characteristics for the move.
Bridges are essential infrastructure, and every cross-chain move runs on one somewhere underneath. But any single bridge only sees its own path. The rate and route it offers may not be the best available for your specific transfer, and you have no comparison unless you check several by hand.
An aggregator: comparison across paths
A cross-chain aggregator compares many bridges and routing engines for the same move and ranks them by what you would actually receive after their costs. It can also combine a swap with the bridge step, so changing both the asset and the network becomes one comparison instead of two manual actions.
The relationship is layered. The aggregator uses bridges and engines as its building blocks, then picks the best combination for your move. You get the outcome of comparing many paths rather than committing to one blind.
- Bridge: one path, with its own fees, speed, and trust model.
- Aggregator: compares many bridges and engines, then ranks by net received.
- Aggregator: can combine a swap and a bridge into a single route.
- Aggregator: does the pricing work you would otherwise do by hand across several bridges.
When each one fits
If you already know exactly which bridge you want and why, using it directly is fine and keeps the flow simple. If you want the best available route without pricing each bridge by hand, especially when a swap is involved as well, an aggregator does that comparison for you and shows the net winner.
The two are not rivals. An aggregator does not replace bridges. It orchestrates them. Bridges remain the roads that carry the value, and the aggregator is the layer that reads all of them and routes your move onto the best one for the trip.
How Multiswap fits this
Multiswap is a cross-chain swap aggregator. It compares routes across engines such as LI.FI, Across, Relay, deBridge, and THORChain, ranks them by net output with costs included, and lets you execute non-custodially, with execution today handled through the Multiswap Telegram bot. The bridges and engines are the roads. The aggregator finds the best one for your trip, and can swap the asset in the same move rather than making you do it separately.
