Travel Rule in Crypto Explained: Why Exchanges Ask Where You Are Sending Funds

The Travel Rule in crypto is a rule under which exchanges pass each other information about the sender and recipient of a transfer. Because of it, withdrawals now come with questions about who you are sending coins to and where.

Below we look at where the rule came from, how it works in practice and why arbitrage traders are better off preparing for it in advance.

What the Travel Rule is in simple terms

The rule was proposed by the FATF, the international body for combating money laundering. In bank transfers, sender and recipient information has long traveled with the payment, and the Travel Rule extends this principle to cryptocurrency.

The obligation lies with providers: exchanges, custodians, exchange services. They must pass on client information along with the transfer and receive the same information for incoming transfers.

Why the exchange asks where you are sending funds

The blockchain only shows addresses. The exchange does not know whose wallet is on the other end, so it asks you.

Your answer determines the route. If the address belongs to another exchange, the information has to be sent to it; if it is your personal wallet, you need to confirm that it is yours.

How the Travel Rule looks in practice

• a question at withdrawal: which exchange or wallet the transfer is going to
• a request for the recipient's name if it is not you
• confirmation that you own a personal wallet, sometimes by signing a message
• a delay on an incoming transfer while the receiving exchange checks the information
• a transfer returned or blocked if the address could not be verified

From what we see, most problems come not from the questions but from mismatched answers. You pick the wrong exchange or your name is spelled differently than in your profile, and the transfer gets stuck in manual review.

How regulators are implementing the Travel Rule

Each country builds the rule into its own legislation, and the requirements differ. Some have an amount threshold below which the rules are softer, while others require information for any transfer.

A recent example is the UK. On October 23, 2026, the FCA opened consultation CP26/38 on updating its financial crime guidance for crypto firms, including blockchain analytics and the Travel Rule, with responses accepted until December 24.

We believe such updates will come out regularly in other jurisdictions too. The rules are tightening gradually, and exchanges adapt their processes to each regulator.

How the Travel Rule affects the speed of transfers between exchanges

In our view, the main danger for an arbitrage trader is unpredictability. A transfer that took ten minutes yesterday may be held for manual review today.

What an arbitrage trader should prepare in advance

• complete verification on all exchanges with the same spelling of your name
• make a test transfer between each pair of exchanges before a real trade
• add your exchanges' deposit addresses to whitelists and note which exchange each one belongs to
• keep a working reserve of coins and stablecoins on both legs of the trade
• note which routes go through quickly and which get held for review

Hypothetical example

The numbers are hypothetical. An arbitrage trader sees a 0.35% difference in a coin's price between exchanges A and B and transfers 5,000 USDT to exchange B.

If the transfer goes through in fifteen minutes, the trade makes it in time. If it is held for manual review for three hours, the difference may have disappeared by then, and the capital sits idle the whole time.

That is why trades that require a transfer at the moment of execution are better replaced with balances spread out in advance. A transfer to rebalance funds can be made calmly once the window has already closed.

Our tools

When transfers between exchanges can be delayed, it pays to know in advance where to keep your balances, and for that it is easier to see all venues in one window. Our arbitrage screener keeps dozens of venues in one window, refreshes quotes every second and shows each gap together with the volume actually behind it. The spread calculator helps you check what survives fees, network costs and slippage at your size. The bot is fully manual. It never connects to your exchange API keys.

FAQ (Frequently Asked Questions)

1. What is the Travel Rule in cryptocurrency?

It is a FATF rule under which providers pass each other information about the sender and recipient of a crypto transfer.

2. Why does the exchange ask where I am sending crypto?

The blockchain only shows addresses. The exchange needs to know who to pass the transfer information to, or that the wallet belongs to you.

3. Why is my transfer between exchanges stuck?

A common reason is a manual Travel Rule check: the wrong receiving exchange was specified, the name did not match the profile, or the exchanges use different information-sharing protocols.

4. Do I need to prove I own my wallet?

Some exchanges ask you to confirm that a personal wallet is yours, sometimes by signing a message. This is usually done once per address.

5. What does the FCA propose in consultation CP26/38?

To update its financial crime guidance for crypto firms, including blockchain analytics and the Travel Rule. Responses are accepted until December 24.

6. How can I speed up transfers between exchanges under the Travel Rule?

Complete verification with the same name everywhere, make test transfers, specify the receiving exchange correctly and keep a reserve of funds on both exchanges.

Conclusion

The Travel Rule brings a banking principle to crypto: information about the sender and recipient travels with the transfer. Hence the questions at withdrawal, the confirmation of personal wallets and the delays when the information does not match.

For an arbitrage trader, this is above all a risk of unpredictable delays. Test transfers, the same name in every profile and balances spread out in advance remove most of the problems before the trade even starts.
