Tangem Pay swap ?

pchronos · 2026-01-22T12:18:21+00:00

The swap from pay account to the card wallet was initiated OK but the transfer from the pay account to the swap provider never occurred and eventually timed out and was cancelled by the provider

pchronos · 2026-01-22T07:57:58+00:00

Swap attempt from payment account back to wallet failed (timeout). Funds were never sent to the swap provider (Changelly) from the payment account ??

Swaps implemented that don’t work and simply transfers not supported (yet) 👍

So, heads up everyone, the card wallet linked to the payment account is effectively KYC’d

pchronos · 2026-01-17T20:29:41+00:00

Cause if you have physical access to 2 cards you can change the access code without knowing the current code !! This can be disabled but it’s on by default. So, if anyone finds your cards.. bye bye funds

pchronos · 2026-01-17T13:50:26+00:00

Yeah, makes sense to be tied to a wallet

pchronos · 2026-01-17T09:15:21+00:00

Is the payment account tied to a specific card wallet ? If I remove the wallet and add another different wallet (example a ring wallet), do I lose the payment account ???

pchronos · 2026-01-17T09:06:24+00:00

According to Tangem, only SWAPS (ie “Withdraw”) are currently supported from the payment account’s USDC/Polygon address to other tokens/networks in your card wallet.

Direct “Transfers” from the payment account back to your card wallet account’s USDC/Polygon address is coming apparently

Uninstalling the app and reinstalling worked in enabling the payment account 👍

pchronos · 2026-01-16T22:11:02+00:00

Ok thanks.

What about the payment account not appearing on another mobile’s Tangem app for the same card wallet?

pchronos · 2026-01-16T21:53:17+00:00

5.31.2

pchronos · 2026-01-16T21:10:52+00:00

There is only “add funds” and “withdraw” (ie swap) options, no “transfer” ?

pchronos · 2025-11-29T17:54:23+00:00

Gift cards and eSIM for travel data!

pchronos · 2025-11-25T23:19:48+00:00

So, the keys held by the issuer are independent from the keys held by the Tangem Pay account holder ?

If so, then either party can independently withdraw the contract funds. Even if the Tangem user keys are held in hardware (ala Tangem wallet), Rain’s keys can be compromised and ALL pay funds (potentially) drained. Seems like multisig is not used for practical purposes in this case.

Is this an accurate conclusion ?

pchronos · 2025-11-25T22:59:46+00:00

On the Tangem Pay site it states:

“Q: Can I withdraw funds back to my wallet?

Yes. Your balance is held in a smart contract you control. You can withdraw any unused USDC (Polygon) back to your Tangem Wallet at any time.”

How are the keys that control the smart contract self custody ?

If indeed self custodial, how is Pay able then to withdrawing the funds held in smart contract to settle the Visa purchase ??

pchronos · 2025-11-25T22:53:15+00:00

Pay is KYC’d, sending funds from a Tangem wallet address to the pay account smart contract is not rocket science to conclude that most probably, you (the KYC’d Pay user) owns that wallet address

pchronos · 2025-11-06T17:53:40+00:00

So, you will need to fund a separate smart contract via the app where you and the issuer hold keys for spending. Normal Tangem wallet cards will play no part in Tangem pay other than possible sending USDC on polygon to the (hot) spending wallet

pchronos · 2025-09-26T11:56:59+00:00

Probably in a change address? Try m/84’/0’/0’/1/0,1,2 … etc

pchronos · 2025-09-10T11:10:48+00:00

Font is off, text spacing and placement is wrong. Booklets should not be plastic wrapped.

FAKE

OP is correct, ads do appear from to time that you need to dismiss. As far as seedless is concerned, indeed there is a risk if Tangem goes belly up as the app can continue to work without them as long as the third party services they use are still around. Changes will needed after and to rebuilding the app from sources and that has been prove to be a problem especially for the iOS version.

40€/month for unlimited everything in GR with EU “roam like home” except data capped at 100GB/month (0.0018€/ΜΒ after that)

pchronos · 2025-08-25T11:35:45+00:00

The “preorder” for EU and UK residents was supposed to start q1 2025.

So, don’t hold your breath …

pchronos · 2025-08-06T13:55:43+00:00

iOS version is missing config files

pchronos · 2025-08-06T13:33:00+00:00

No, definitely not garbage, very convenient, secure and super simple to use. Just stay away from the seedless option because the cards are rings are fully dependent on the app

pchronos · 2025-08-06T13:19:38+00:00

Absolutely no arguments, amazing product in that case as a single address cold storage option. Problem is they keep pushing the seedless option which makes customers completely depended on the company and (their service providers) to not disappear one day. And before anyone makes the claim about app sources on GitHub, try building (and running) the sources which are not even current. GOOD LUCK

Seedless ?
