Why crypto payments are broken today
❌ Manual steps
Customers copy wallet addresses and select chains. One mistake and funds are gone.
❌ Failed transactions
Wrong fees, stuck swaps, or low liquidity lead to lost payments.
❌ Poor user experience
Customers must swap or bridge before paying, causing drop-offs.
❌ No reliability
Unlike fiat payments, there’s no guarantee a crypto transaction will succeed.
Lost revenue, frustrated users and endless support tickets.
How does Unter work for your users.
Paying with crypto should feel save and easy.
1. Choose their wallet
They connect any supported wallet.
2. Pick their token
They pay with the asset they already hold.
3. Unter does the rest
Swaps, bridges and routing happen automatically in the background.
4. Get clarity
They see a clear overview of the payment and receive instant confirmation.
Introducing Unter
Unter acts like an invisible aggregator, swapper, bridge, validator, optimizing and correcting every payment in a secure way.
Smart crypto payments
Unter runs the engine behind the scenes so every payment feels smooth and effortless.
Automatic routing, swaps and bridges
Unter always finds the fastest route, handling conversions instantly so payments never get stuck.
Any token, any wallet, any chain
Let your customers pay with what they already hold, from Ethereum to Solana and everything in between.
