You cannot use Replace-By-Fee on an exchange withdrawal, because the exchange holds the keys and signed the transaction. Your real options are CPFP on the output you received, asking the exchange to bump it, or waiting. This is also the one situation where paying for acceleration can be genuinely justified.
This is the most frustrating version of a stuck transaction, because the standard advice does not apply to you. Every guide says bump the fee. You cannot. The exchange built and signed that transaction, and only whoever holds the keys can replace it.
Before the options, one warning that matters more than anything else on this page.
Those support phone numbers are scams
Search results for stuck exchange withdrawals are full of pages carrying phone numbers claiming to be Coinbase, Binance or Kraken support. They appear on quote sites, forum reposts and scraped content farms. None of the major exchanges provide phone support for this. Calling one connects you to somebody who will ask for your credentials, your seed phrase, or a payment to release funds. Contact exchanges only through the support link inside their own app or website.
First, work out whether it has even been broadcast
Exchange withdrawals move through several stages before they touch Bitcoin at all, and most of the delay usually happens before the network is involved.
| What you see | What it means | Can Bitcoin help |
|---|---|---|
| Pending, no transaction ID | Not broadcast yet. Internal review, batching or a security hold | No, nothing exists on chain |
| Transaction ID, unconfirmed | It is on the network and waiting for a miner | Yes, read on |
| Transaction ID, confirmed | Bitcoin is finished. The receiving side is the delay | Nothing left to do |
If there is no transaction ID, stop reading technical guides. Nothing about fees, mempools or accelerators applies, because there is no transaction. That is a support question for the exchange.
Why you cannot use RBF
Replacing a transaction means signing a new one that spends the same inputs. Those inputs belong to the exchange's wallet, not yours. Without their private keys you cannot produce a valid replacement, and no service can do it for you either.
This is worth stating plainly because plenty of accelerator marketing implies otherwise. Nobody can bump somebody else's transaction. What a paid accelerator does is different, and it is covered further down.
Option one: CPFP on the coins you received
This is usually the best lever available. You cannot change their transaction, but once it pays out to your address, you control that output. Spending it in a new transaction with a generous fee makes miners want the pair together.
The mechanics, the fee formula and a worked example are in the CPFP guide. The short version is that you send a small transaction to yourself, spending the incoming output, paying enough that the combined package clears the current rate.
The catch with batched withdrawals
Exchanges frequently batch many customer withdrawals into one transaction. If yours is batched, your output is one of dozens, and a CPFP from you lifts the entire batch. That means your child has to carry the fee for a much larger parent, which can make it expensive or impractical.
Check the transaction on an explorer. If it has fifty outputs, it is a batch and CPFP may not be worth it.
Option two: ask the exchange to bump it
They can replace their own transaction, and the larger exchanges do have processes for this. Whether they will depends on the platform and how you ask.
What to write
Support agents handle a lot of vague messages. A specific one gets routed correctly:
- The transaction ID.
- The fee rate it paid, in sat/vB, taken from an explorer.
- The current next-block rate, so the gap is obvious.
- A direct request: please rebroadcast this withdrawal with a higher fee using RBF, or perform a CPFP from the change output.
Naming the mechanism matters. It signals you know what you are asking for and gets the ticket to somebody technical faster.
Platform by platform
Coinbase
Coinbase batches withdrawals heavily and generally sets fees itself. Support exists through the Help Centre in the app, starting with an automated assistant that escalates to a human. There is no phone line for this. Because of batching, CPFP from your side is often impractical, so support and patience are the realistic routes.
Binance
Binance publishes withdrawal status in the transaction history, and a pending state without a transaction ID usually means internal processing rather than a network delay. Once broadcast, their fees are typically set well above the clearing rate, so genuine sticking is uncommon. Use in-app support and quote the transaction ID.
Kraken
Kraken tends to be more transparent about fee selection and its support is generally responsive to fee bump requests referencing a specific transaction ID. Of the large exchanges, this is the one where asking is most likely to work.
Cash App and Strike
Both are more consumer oriented with less granular control. Support is in-app only. CPFP from your receiving wallet is often the faster path if the payment reached an address you control.
Smaller exchanges
Variable, and the risk profile is different. A withdrawal that never gets a transaction ID from a small platform can indicate liquidity problems rather than a network issue. If a transaction ID never appears after a long delay, escalate rather than waiting quietly.
Option three: when paying for acceleration is justified
We spend most of this site arguing that paid acceleration is usually a waste, and our measurements back that up. This is the exception, and it is worth being fair about it.
The honest case requires all three of these to be true:
- You genuinely cannot bump it. The exchange will not, and CPFP is impractical because the withdrawal was batched.
- The transaction is genuinely underpriced. Check the rate against the current clearing rate rather than assuming.
- The delay actually costs you something. A closing window, a counterparty waiting, a deadline.
If all three hold, paying a pool to prioritise it is a reasonable purchase. Check the real shortfall first so you know whether the quote is three times that number or seventeen times.
Check the withdrawal before you decide
Paste the transaction ID. We show whether it is batched, its effective fee rate, the current clearing rate, and the actual shortfall in satoshis.
How to avoid it next time
- Withdraw during quiet periods if timing is flexible. Weekends are usually cheapest.
- Prefer exchanges that let you choose the fee. Some do, and it removes this problem entirely.
- Withdraw larger amounts less often. Fees scale with size, not value, so one large withdrawal costs the same as a small one.
- Keep a small on-chain balance elsewhere so you are never dependent on a single withdrawal clearing quickly.
- Note the transaction ID immediately. It makes every later conversation faster.
The bottom line
Check for a transaction ID first, because if there is none the Bitcoin network is not your problem. If there is one, look at whether it is batched. Unbatched means CPFP is available to you and cheap. Batched means asking support is the sensible first move, with acceleration as a paid fallback when the delay genuinely costs more than the quote.
And ignore any phone number offering to fix this. The exchanges do not have one.

Frequently asked questions
Why can I not speed up an exchange withdrawal myself?
Because Replace-By-Fee requires signing a new transaction that spends the same inputs, and those inputs belong to the exchange. Only the holder of the private keys can produce a valid replacement. No third party service can do it on your behalf either.
Are the Coinbase or Binance support phone numbers in search results real?
No. The major exchanges do not provide phone support for stuck withdrawals. Those numbers appear on quote sites and scraped content farms and connect you to scammers who will ask for credentials, a seed phrase or a payment to release funds. Only use the support link inside the exchange's own app or website.
My withdrawal is pending but there is no transaction ID. What does that mean?
It has not been broadcast to the Bitcoin network yet. The delay is internal to the exchange, from batching, review or a security hold. Nothing about fees, mempools or accelerators applies, because no transaction exists on chain yet. That is purely a support question.
Can I use CPFP on an exchange withdrawal?
Yes, if the payment reached an address you control and the withdrawal was not batched. Spend the incoming output in a new transaction paying a high fee, and miners take both together. If the exchange batched many customers into one transaction, your child would have to lift the whole batch, which is often impractical.
Should I pay an accelerator for a stuck exchange withdrawal?
Only if three things are true at once: you genuinely cannot bump it, CPFP is impractical because the withdrawal was batched, and the delay actually costs you something. This is the one scenario where paid acceleration is defensible. Check the real fee shortfall first so you know whether the quote is reasonable.
How do I ask an exchange to bump my withdrawal?
Contact support through the app and give them the transaction ID, the fee rate it paid in sat/vB, the current next-block rate, and a direct request to rebroadcast with a higher fee using RBF or to perform a CPFP from their change output. Naming the mechanism gets the ticket to a technical agent faster.
