Swap
Compare routes. Keep control.
Swap supported assets within a network or across networks. Smartable shows the options available for the pair and amount you choose. You select an option, review its terms, and approve it from your wallet.

- No automatic route selection
- Review before approval
What you review
The details before you approve
Choosing an offer opens its review. Nothing is approved or signed until you confirm it.
- Asset pair
- What you send and the asset you expect to receive.
- Expected output
- What the route expects to deliver, and the minimum it commits to where it gives one.
- Fees
- Listed as the route reports them. Some providers fold theirs into the amount. The network fee is shown on its own line.
- Route details
- Estimated time, the networks involved and any conditions specific to the route.
- Provider
- Named in the app before you choose and approve a route.
You choose
Compare available options
Smartable does not rank options or choose a route for you. Compare expected output, fees and route details, then select the option you want.
Availability depends on the asset, network, amount and current liquidity. A route can be unavailable even when another option for the same pair works. If an offer changes while you review it, you choose again — the app never moves you to another provider.

Cross-chain swaps
Different networks, different settlement
A cross-chain swap is not one atomic transaction. Your asset leaves the source network before delivery is completed on the destination network.
Settlement depends on the route and can involve a bridge contract, a relayer or a market maker. Smartable does not take custody of your assets. The review identifies the provider for the selected route before approval.
Source network
Leaves your wallet
Selected route
Bridge contract, relayer or market maker
Destination network
Delivered to the destination address
Cross-chain caution
Submitted transactions cannot be reversed from the wallet. What happens if delivery is delayed or fails depends on the route — review its details before approval.
Route checks
Built to reject the unexpected
Before approval, Smartable checks the route against the transaction, the expected contracts or programs, and the wallet’s safety policy. A route that fails a required check is refused before anything is approved or signed.
- The route contract, program or spending permission matches the selected route.
- Where an approval is needed, it is confirmed separately and requests only the amount for that trade — never an unlimited allowance.
- The transaction moves only the asset and amount you chose.
- The route meets the wallet’s current custody and safety policy.
- When an independent market reference is available, a quote materially out of line with it is refused.
Checks apply where the route exposes verifiable data. Where supported, Smartable also simulates the transaction and rejects one that would move more than you selected.
