The key difference
A swap changes one asset into another, usually on the same blockchain. A bridge moves an asset or value between blockchain networks. The two concepts answer different questions.

Bridge vs Swap: What's the Difference?.
Learn when a bridge, a swap, or a combined route is the right tool for a crypto transaction.
Where each approach fits
If the network stays the same and you need a different token, look for a swap. If the token stays the same but the network changes, look for a bridge. Some real transactions require both.
What to compare
Cross-chain aggregators can combine bridging and swapping into one route. The route may therefore show multiple steps even when the user starts with one token and expects another token on the destination chain.
Bottom line
Always check both dimensions before signing: which asset you are sending and which network you will receive it on. This avoids the common mistake of confirming a correct token on the wrong chain.
