Outgoing planned post announcing improvement to Tangem App
Version 5.37 is available now on iOS and Android. This release is a big one for swaps; more control, better transparency, and fewer rough edges across the board.
Version: 5.37
Operating System: iOS and Android
Date: April 30, 2026
When you use Send via Swap, you can now choose a fixed rate for your swap. That means the rate you see when you confirm is the rate you get, regardless of what the market does while your transaction is processing.
If price certainty matters more to you than chasing the best available rate in the moment, a fixed rate gives you that guarantee. It's a straightforward addition that makes a real difference when you're swapping larger amounts or moving between volatile assets.
If there's a significant gap between what you're sending and what you'll receive in a swap, the app will now flag it before you confirm.
Slippage, fees, and liquidity conditions can all eat into a swap in ways that aren't always obvious at first glance. This warning makes sure you avoid being caught off guard by a bad rate and gives you a chance to reconsider before anything is signed.
USDT on Ethereum has a quirk: before you can approve a new spending allowance, you sometimes have to reset the existing one first. If you've ever tried to increase your USDT allowance for a swap and hit an unexpected wall, this is what was happening.
In 5.37, the app now handles this properly. You can re-approve a higher allowance directly, without manually resetting anything. It just works.
If you're using Multi-Accounts, the swap screen can get busy fast. You can now collapse accounts in the swap interface to keep things clean and focused on what you actually need. It's a small UI improvement that makes a meaningful difference if you're managing several accounts at once.
If you're sending to an XRP or XLM address that requires a memo — common when sending to exchanges, the app will now display a warning to help you remember.
Missing a memo on these networks can leave your funds in limbo. This warning is a straightforward safeguard that's easy to overlook until the one time you need it.
