The short answer
Bridge aggregation means evaluating multiple available cross-chain providers and routes for a user's requested source, destination, asset and amount. The goal is to surface viable paths without requiring users to research every provider manually.
How it works
An aggregator can consider price, liquidity, fees, execution steps and provider availability. The best route can change as market and network conditions change.
Why it matters
Aggregation does not remove the underlying risks of the providers or smart contracts used in the route. Users still need to review wallet transactions and destination details.
Practical takeaway
OneSwap uses LI.FI routing infrastructure to surface supported cross-chain paths. The live result is the best source for current route availability and pricing.
