The short answer: payment apps are not exchanges, and they treat every outgoing crypto transfer as a payment they are responsible for. When a send fails, it is almost always one of five things: you hit a weekly or daily limit, the destination address was flagged, your account or location triggered a check, the app wants proof you own the wallet, or the transfer was held as a possible scam. Each one has a different fix, and a couple of them have no fix at all inside the app.

Revolut says it plainly in its own help centre: if it decides an address is linked to an exchange it does not support, it blocks all future withdrawals to that address, even if earlier transfers to it went through, and a rejected address cannot be unblocked. That single rule explains a large share of the "it worked last month and now it doesn't" messages people send us.

This guide covers the three apps people ask about most, with the rules taken from their own help pages as of September 2026. One disclosure: we run CoinVast, a swap service people often try to send coins to from these apps, so this problem lands in our inbox regularly. We describe each app's rules as they state them, not as we would like them to be.

The rules side by side

PayPal (US) Revolut Cash App
Coins you can send out BTC, ETH, LTC, BCH, SOL, LINK, PYUSD Varies by country and coin Bitcoin only
Transfer limit $25,000 a week, internal and external combined Daily and monthly limits set per account, shown in the app Raised fivefold for eligible customers in February 2026; reported at $10,000 a day and $25,000 a week
When the limit resets Thursday for personal accounts Daily limit 24 hours after your last withdrawal, monthly limit 30 days after Rolling
Address checks Crypto sent to a wrong or unsupported network is lost Addresses reviewed; addresses linked to unsupported exchanges blocked for good Standard fraud checks

Minimum to send out 0.001 BTC, 0.01 ETH, 0.01 LTC, 0.01 SOL Shown per coin in the app Shown in the app

Limits in these apps move with your account history and your country, so treat the table as the published rule and the figure in your own app as the one that applies to you.

The five reasons a transfer gets blocked

1. You hit a limit

This is the most common one and the easiest to confirm. PayPal counts internal and external transfers against the same $25,000 weekly limit in the US, and that limit resets on Thursday for personal accounts. Revolut applies separate daily and monthly limits, and it resets them relative to your last withdrawal rather than on a calendar date: send on March 2 and your monthly limit comes back on April 1. Revolut can also put a separate, lower limit on one specific address based on its assessment of that address, which you will see on the address selection screen.

Fix: wait for the reset, or split the transfer across the reset date. There is no way to raise a limit on the spot.

2. The destination address was flagged

Payment apps screen the address you are sending to. Revolut reviews addresses at several stages, and its automated checks can disable an address you have used before. The rule that surprises people most is the exchange rule: an address the app decides belongs to an exchange it does not support is blocked permanently. Revolut's help page is explicit that there is no option to unblock a rejected wallet.

Fix: you cannot appeal a rejected address inside the app. The practical route is to send to a wallet you control first, then onward from there. More on that below.

3. Your account or location triggered a check

Revolut blocks withdrawals when a device location is flagged as a high risk or sanctioned jurisdiction, and it tells you to retry once you are back in the country where you opened the account. A temporary restriction on your account blocks crypto sends as well, and PayPal disables transfers while your balance is negative or a bank funded purchase is still settling, which can take several days.

Fix: check your notifications and email for a restriction notice first. If you are travelling, wait until you are home. If a purchase is still settling, wait for it to clear.

4. The app wants proof that you own the wallet

Under the EU Travel Rule, a regulated provider sending crypto to a self hosted wallet has to know who controls it. Revolut's crypto terms say a self declaration is not always enough and that it may ask for technical proof of ownership, such as signing a message with the wallet, before releasing the funds. PayPal can hold a transfer for up to 30 days while it waits for recipient information, and returns the coins if the details never arrive.

Fix: complete the ownership check in the app. Signing a message proves control of an address without exposing your keys, and most good wallets can do it in a minute.

5. It looked like a scam

Every transfer is scored for fraud risk. Revolut says that when a send looks highly likely to be a scam it will either warn you in app and ask you a series of questions, or cancel the transfer itself. These checks exist because scammers often talk victims into buying crypto in a payment app and sending it on.

Fix: answer the questions honestly. If someone you met online, a "support agent" or an investment coach told you to make the transfer, stop, because that is the pattern the check was built to catch.

Which error you are probably looking at

What you see Most likely reason What to do
Transfer fails right away, same amount worked before You hit a limit Check the limits screen and wait for the reset
One address fails, other addresses work The address was flagged or linked to an unsupported exchange Send to your own wallet first, then onward
Every send fails with a location message Device location flagged Retry once you are back in your home country
App asks you to prove the wallet is yours Travel Rule ownership check Sign a message from the wallet or use the app's check
App asks questions about who told you to send Scam screening Answer honestly and stop if someone is directing you
Transfer is pending for days Held for review or recipient information Wait, and read your email for a request

The route that avoids the blocks

Most blocks happen because the app is judging the final destination: an exchange it does not support, an address it cannot place, a pattern it reads as risky. The way through is not to fight the check but to change the destination to something the app accepts, a wallet you control.

  1. Install a self custody wallet for the coin you are sending. For Bitcoin, any mainstream wallet that lets you see and back up your recovery phrase works.
  2. Send a small test amount from the app to your own wallet first, and complete any ownership check the app asks for.
  3. Send the rest once the test arrives.
  4. Move onward from your own wallet. Once the coins are in a wallet you control, the payment app's rules no longer apply, and you can send them wherever you like, including to a swap. If you are converting to a privacy coin, a BTC to XMR swap from your own wallet takes about as long as the Bitcoin confirmations.

Two warnings. Never let anyone else control the wallet in step 1, and never share your recovery phrase with anyone who says they will help you get around a block. Both are how people lose everything after a perfectly legitimate transfer.

Frequently asked questions

Why did Revolut block a crypto address that worked before?

Because Revolut reassesses addresses over time, and its help centre says an address linked to an exchange it does not support will be blocked for all future withdrawals, even if you sent to it successfully before. A rejected address cannot be unblocked, so the fix is to send to a wallet you control instead.

What is PayPal's crypto transfer limit?

In the US, PayPal allows up to $25,000 a week in crypto transfers, counting internal and external transfers together. The personal account limit resets on Thursday. Minimum external transfers are 0.001 BTC, 0.01 ETH, 0.01 LTC and 0.01 SOL.

How much bitcoin can I withdraw from Cash App?

Cash App raised its bitcoin withdrawal limits fivefold for eligible customers in February 2026, and the new limits are widely reported as $10,000 in any 24 hours and $25,000 in any 7 days for verified accounts. Newer or unverified accounts get lower limits, and your exact figure is shown in the Bitcoin section of the app.

Why does my app ask me to prove I own my wallet?

Because of the Travel Rule, which requires regulated providers to know who controls a self hosted wallet they send crypto to. Revolut may ask for technical proof such as a signed message rather than accepting your word. Signing proves you control the address without revealing your keys.

Can I send crypto from PayPal to an exchange?

PayPal supports sending crypto to other wallets and exchanges, but the coins must go on a network PayPal supports and within your weekly limit. Crypto sent to the wrong address or over an unsupported network is lost, so always send a small test first.

Is it safe to use a wallet to get around an app's block?

Sending to a wallet you control is the normal, intended use of a crypto transfer, not a trick. What is not safe is letting a stranger guide you through it or handing anyone your recovery phrase. If someone is pushing you to get around a block, treat that as a warning sign of a scam.
