The Bottom Line

When you send Bitcoin to an exchange but the deposit isn't showing up in your balance, the very first thing to do is look up the TXID (transaction ID) generated when you sent the coins in a block explorer, and determine whether the transaction actually went through and how many confirmations it has. In most cases, this is simply a matter of waiting for the transaction to reach the number of confirmations your exchange requires — for Bitcoin, around 3 confirmations typically take 30 minutes to an hour. If the block explorer shows the transaction is confirmed on-chain, do not panic and send it again. Only when confirmations aren't accumulating, or the transaction can't be found at all, should you suspect a different cause such as falling below the minimum deposit, maintenance, or a wrong destination.

Key takeaways

- The first step is always "check the TXID in a block explorer" — this separates the send from the receipt

- Exchange deposits don't credit until they reach the required number of confirmations (e.g., 3 confirmations at Coincheck and bitFlyer)

- Other reasons for a missing deposit: falling below the minimum deposit amount, maintenance, or a wrong destination address or unsupported network

- Double-sending is a way to lose funds. Always provide your TXID when contacting support

Step one: is the transaction actually on-chain?

"It's not showing up" can mean two completely different things, and confusing them leads to the wrong fix.

  1. The transaction went through and you're waiting for the exchange to credit it (= normal; this is most cases)
  2. The transaction never made it onto the blockchain, or went to a different destination (= needs action)

The deciding piece of evidence is your TXID — a string of around 64 alphanumeric characters shown in your sending wallet or the exchange's withdrawal history. Paste it into a block explorer such as mempool.space or Blockchain.com Explorer and you'll see exactly where your bitcoin is right now. For the full picture of sending, see How to send Bitcoin.

Cause 1: waiting to reach the required confirmations (most common)

Every time a Bitcoin transaction is included in a new block, it gains one more "confirmation." To prevent fraud and double-spending, exchanges only credit your balance once a certain number of confirmations is reached. This confirmation mechanism is explained in detail in What is a confirmation?.

The required number varies by exchange (the official help pages are authoritative and can change, so always check the latest with each provider).

Exchange (example)Bitcoin confirmations requiredApproximate time
Coincheck3 confirmationsAbout 30 min+
bitFlyer3 confirmationsAbout 30 min+
Kraken4 confirmationsAbout 40 min

Because Bitcoin is designed to produce a block roughly every 10 minutes on average, 3 confirmations take at least around 30 minutes, and longer if the network is congested. During this window, "not showing up" is normal — waiting is the right move.

Cause 2: below the minimum deposit amount

Many exchanges set a minimum deposit amount below which a transfer won't be credited. For example, bitFlyer sets its minimum deposit at 0.0004 BTC, and transfers below that may not be credited or received (amounts and conditions can change, so always verify with the official source before sending). If you're doing a small test transfer, be careful not to fall below this floor.

Cause 3: maintenance or a temporary deposit halt

If an exchange has temporarily suspended deposit processing for system maintenance or to address a blockchain issue, your balance may be delayed even though the coins have already arrived on-chain. In this case, confirmations are more than sufficient but crediting alone is stalled. Check the exchange's incident and maintenance notices (announcements / status page). Deposits usually credit automatically once processing resumes.

Cause 4: wrong destination address or network

  • Copy error in the address: even one wrong character sends to a different destination. Bitcoin addresses come in several formats that look different from one another (Types of Bitcoin addresses).
  • Wrong network: some exchanges display multiple networks for Bitcoin (e.g. native BTC and wrapped variants). If you don't send to the exact network and address the exchange specified, it won't be credited.
  • No tag/memo needed: Bitcoin deposits normally don't require a destination tag, but check that you haven't entered one out of habit from another coin.

If the explorer reveals the destination isn't what you intended, you often can't recover the funds yourself, so contact the exchange promptly with your TXID.

Never double-send

Sending again "because it isn't showing up" risks having both transactions arrive and paying twice (= losing funds). The correct order when a deposit isn't credited is: "① check the TXID in an explorer → ② if confirmations are progressing, wait → ③ if it still doesn't credit, contact the exchange with your TXID attached."

What to tell the exchange when you contact support

If you can't resolve it yourself, gathering the following before contacting support will make things go smoothly.

  • TXID (most important — investigation is often impossible without it)
  • The source (your wallet name / another exchange name) and the destination address
  • The date, time, and amount sent
  • The current number of confirmations shown in the block explorer
  • The network you used to send

Frequently asked questions

Q. It's been an hour and still nothing. Is it broken?

Not necessarily. Confirmations slow down when the network is congested. Look up your TXID in an explorer, and if confirmations are accumulating, the right move is to wait until it reaches the exchange's required count. If confirmations stay at 0 for a long time with no movement, see what to do when a transaction won't confirm.

Q. I can't find where my TXID is.

It appears in your sending wallet, or in the detail view of your exchange's "withdrawal history," as a string of around 64 alphanumeric characters (the transaction ID). Copy it and paste it into a block explorer's search box.

Q. It reached 6 confirmations but my balance still hasn't increased.

Even with plenty of confirmations, the exchange's deposit processing may be halted (maintenance or an incident). Check the exchange's announcements, and if that doesn't explain it, contact support with your TXID attached.

Q. Since it isn't showing up, can I just send it again?

Wait. Re-sending risks a double payment. First check the status with your TXID, and as a rule, don't send anything more until the cause is identified.
