With the EU-wide TFR (Transfer of Funds Regulation), all brokers and exchanges operating in Europe, including Coinfinity, are required to implement the Travel Rule.
In this support article, you will learn what this means for you specifically and how you can add and confirm your external self-hosted wallets on Coinfinity. Transactions to and from custodial wallets (e.g., at another crypto exchange) are no longer possible with us. We have made a conscious decision to refrain from this in order to ensure that no data needs to be exchanged.
Important note
The Coinfinity in-app wallet is easier to use than external wallets in many ways. We explain the differences here:
Coinfinity In-App-Wallet
All processes run automatically in the background.
No manual addition or confirmation required
You retain full control
External wallets
Add: From now on, the wallet address or extended public key must be added for every Bitcoin purchase or sale with external wallets.
Confirm: From now on, under certain circumstances (see below), in addition to adding an external wallet, confirmation is also required.
Existing savings plan addresses from external wallets are automatically added as wallets, but are not automatically confirmed.
Quick check: When do I need to confirm a wallet?
✅ No confirmation is required if:
You only use the Coinfinity in-app wallet
Your savings plan runs into the Coinfinity in-app wallet
Your savings plan is less than EUR 999 and goes to an external wallet
You send Bitcoin from the in-app wallet to an external self-hosted wallet (e.g., hardware wallet)
You make individual purchases under 999 EUR to external wallets
For purchases made in the Coinfinity in-app wallet, we automatically handle the confirmation in the background. No additional confirmation is required for transfers from the in-app wallet to another wallet or vice versa. The in-app wallet is and remains under your control.
For individual purchases under EUR 999 to external wallets, it is sufficient to simply provide the address or extended public key—no additional confirmation is required.
⚠️ Confirmation required if:
You want to buy Bitcoin directly to an external wallet via a single purchase over EUR 999
You have set up or want to set up a savings plan of more than EUR 999 directly to an external wallet
You want to sell Bitcoin from an external wallet
In these cases, in addition to adding the wallets or addresses, you must also confirm them before you can trade with them. If you buy into the Coinfinity in-app wallet as an intermediate step and then send Bitcoin from there to an external wallet, you do not need to do this.
📋 New features with this update
Add multiple external wallets
Archive and manage wallets
Add single addresses or XPUBs
Automatic use of unused addresses with XPUB
Confirmation options
For the time being, you can only verify your wallets on the web portal and, in some cases, in the app. You have two options:
Confirm individual Bitcoin addresses
2. Confirm Extended Public Key (XPUB) – This is particularly useful if you want to switch addresses, as it allows you to confirm all addresses linked to your wallet at once.
Supported wallets and instructions
We have implemented various technical solutions to make the process as smooth as possible for you:
Automation: Everything runs automatically in the background for our in-app wallet
AOPP support: Some hardware wallets can perform the confirmation process automatically
Step-by-step instructions: We provide detailed instructions for all common wallets.
For each wallet, we provide you with individual step-by-step instructions on how to sign your wallet or individual addresses.
Software wallets
Hardware wallets
Other wallets
Key details
Time frame
Effective immediately: Adding external wallet addresses or XPUB required for all transactions
Additional confirmation: Only necessary in the cases mentioned
Amount limit
For amounts up to EUR 999 per purchase to external wallets, simply adding the address is sufficient—no additional confirmation is required.
Existing wallet addresses
Addresses that you have used for purchases or sales in the past do not need to be confirmed retrospectively. However, if you plan to use existing addresses in the future, you must confirm them before the next transaction if the above criteria apply.
Special features and important information
Differences between buying and selling
For purchases: It is usually sufficient to confirm individual addresses
For sales: Confirmation of the extended public key (XPUB) is mandatory here, as outgoing transactions often consist of UTXOs from multiple addresses
Possible delays
To avoid delays and problems, we ask you to add your wallet addresses to the Coinfinity web portal or app today so that you can carry out your future transactions quickly and easily as usual.
Data security and privacy
Your privacy and control over your Bitcoin are our top priority. That's why we only support self-custodial or self-hosted wallets for verification – only you have access to your private keys. This remains the case even with the introduction of the Travel Rule: when proving wallet ownership, no data is exchanged with third parties.
We have deliberately made it impossible to send and confirm transactions with custodial wallets. We have chosen not to offer this feature in order to ensure that no data needs to be exchanged. Our principle is clear: not your keys, not your coins.
Please note that each newly added wallet or address must be approved by you via email code (one-time password).
What is the Travel Rule?
The TFR (Transfer of Funds Regulation) is a legal requirement of the European Union and implements the requirements of the Financial Action Task Force (FATF) “Travel Rule.” It obliges CASPs (Crypto Asset Service Providers) to collect certain information during transactions and, if necessary, to transmit it to other financial service providers when cryptocurrencies such as Bitcoin are transferred between different providers.
As a regulated provider in Austria and thus in the EU, we comply with the applicable regulations. This means considerable additional effort for us—from technical infrastructure and specialized compliance personnel to continuous system updates. This is how we ensure that our services meet the highest standards.
