What a Bitcoin address is and how to use one safely

What an address is and what it is not

An address is the part of Bitcoin you hand out. It receives coins on your behalf, and a wallet can produce as many of them as you need. Sharing it does not hand over control of the funds sitting behind it.

Each address is derived from a key that the wallet holds privately. The address is calculated from that key, but the calculation runs one way only, so publishing the address does not expose the key or the coins. That is why an address is safe to share with someone who is paying you.

It is not a password, and it is not the recovery phrase that can rebuild a whole wallet. Nor is it your login to an exchange, which is a separate account with its own credentials. Treat those items as private; treat the address as public.

To the eye, an address looks like a long random mix of letters and characters. You are not expected to memorise it, and you should not type it from memory either; copy it from the wallet instead, as covered in the wallets guide.

Anyone can look up the record of an address on a public explorer and see the transactions tied to it. The amounts and the timing are visible, though the people behind them are not named. That visibility is why privacy habits matter: reuse one address everywhere and you make it easier for strangers to connect your payments together.

Where you find your address

Your address lives in the wallet or account that holds the coins, and you get it from that software rather than from a friend or a note. In a wallet app, look for the screen that shows incoming payments: it displays the address as text and as a QR code you can let the payer scan. A platform works differently, since the address sits on the page for adding that particular coin to your balance.

What matters is where the address came from. It belongs to the wallet or account that produced it, so an address shown by someone else is their address, not yours. Pasting it into your own wallet does not make it yours, and coins sent there go to whoever controls it.

Saved addresses may not be current. An address copied into a note months ago may no longer be the one the wallet is showing. Open the app and read the address fresh before each payment.

On a platform, confirm the coin and the network named beside the address before you share it, because a page for one coin can look much like another. If a payer asks you to send a screenshot, check that the address in the image matches the one on screen.

A fresh address for every payment

Many wallets produce a new receiving address each time you open that screen, and this is deliberate. The public record shows every payment that lands on a single address, so anyone who looks it up can count the transactions and see their timing. Paying into a fresh address each time makes it harder to tie your payments to one another.

An old address does not stop working. Coins sent to one you used before still arrive, because the wallet keeps the key behind it. The risk is privacy rather than loss: reuse the same address for every payment and you build one visible history that strangers can follow.

Getting a new address takes little effort. Open the receive screen in the wallet, copy the address it displays, and check it against the screen before you pass it on. Some wallets label this as a receive or deposit screen; the address shown there is the current one.

Reuse matters less in narrow cases, such as a single payer you already trust sending a repeat payment. It matters more when the address is public, posted in a group chat or printed on an invoice that many people see.

If a payer insists on an old address, you can still accept the coins there. Read the address back to them to be sure you both mean the same one, and remember the payment will be linked to your earlier activity on that address.

Copy, paste and check both ends

Copying an address by hand invites errors, so the practical habit is to copy it from the wallet and paste it into the payment field without retyping. Paste removes the risk of a mistyped character, but it does not remove the need to look. Before you confirm, compare the pasted address with the source on screen.

Read the first few characters and the last few, then pick a small group from the middle and compare those too. Attackers sometimes write software that swaps a copied address for another one on the clipboard, so the value that lands in the field may differ from the one you copied. Checking both ends and the middle catches that swap before the coins leave.

A QR code avoids typing altogether, which is why many people prefer it for sending. The code can be replaced too, particularly on a fake page that imitates a familiar site, so scan from the wallet screen you opened yourself rather than from a link someone sent. Match the address the code produces against the one displayed beside it.

For a large send, read the address aloud to a second person and let them compare it with the screen. Two sets of eyes on the same characters catch slips that one person skims past, and the check takes less time than sorting out a transfer sent to the wrong place.

Same network, same coin

An address belongs to a particular coin on a particular network, and the format reflects that. Treat Bitcoin addresses and Bitcoin Cash addresses as belonging to different coins; an address for one should not be used for the other. Send coins to an address belonging to a different coin and the receiving wallet may not recognise them, which can put the funds out of reach.

Bitcoin and Bitcoin Cash are separate coins with separate histories, even though they share a common origin. Bitcoin Cash began as a fork of Bitcoin, and the two have followed their own paths since. Because the names sit close together in a list, mixing them up is a known mistake; read the coin name on the screen before you copy anything. The Bitcoin Cash profile sets out how that coin differs from Bitcoin.

Platforms add a layer of confusion by supporting more than one network for the same coin. On a deposit page you may see the coin named at the top and a network named beside the address, and both need to match what the sender is using. An address that looks correct can still be for the wrong network, and coins sent across networks do not arrive where you expect.

Before you pass an address to anyone, look at the label beside it and ask the payer to confirm the same coin and network on their side. Ask them to read the label back to you rather than assume it. That single check, done before the coins move, is the one that prevents this class of loss.

A small test first, then confirmations

Before sending a full amount to a new address, send a small amount first and wait for it to arrive. Treat that first payment as a check on the address, the coin and the network together. If something is wrong, the loss is small rather than the whole sum.

A payment does not settle the moment you press send. It sits as pending until the network includes it in a block, and blocks are added about every ten minutes. The receiving wallet may show the coins as pending too, so do not assume the transfer failed just because the balance has not moved.

Each block added on top of the one holding your payment counts as a confirmation. A few confirmations make the payment more settled, and platforms often wait for several before crediting a deposit. Ask the receiver how many they require before you plan the rest of the transfer.

Busy periods can stretch the wait, because block space is limited and payments compete for it. Our guide to Bitcoin fees explains how that competition works and why a payment can sit longer than expected.

Only send the remainder once the test has arrived and the receiver confirms it. If the test has not shown up, stop and check the address and network again rather than sending more.

Mistakes that cannot be reversed

A bitcoin payment has no bank behind it that can step in and pull the money back. Once the network confirms a transfer, the coins sit in the wallet that controls the receiving address, and only the holder of that wallet's keys can move them. There is no branch to call, no card issuer to raise a dispute with, and no phone line that can freeze a transaction while you explain.

This applies to every kind of mistake covered earlier: a wrong address, a wrong network, or a payment sent to someone who was never going to deliver. Each ends the same way, with coins gone from your control. The network did exactly what it was told.

If a platform held the wallet at either end, contact its support team straight away. They can sometimes intervene in narrow cases, such as a deposit that landed in an account the platform controls, but they cannot promise to recover anything. Be honest with yourself about the odds: most wrong-address payments are simply gone.

Then stop and write down what happened while it is fresh. Record the transaction details from your wallet, including the address you sent to and the network you used, and keep screenshots. If a platform was involved, give that record to its support team rather than sending money again.

Watch for people who message you claiming they can recover the coins for a fee. Treat those offers as a second scam aimed at the same loss.

Address habits in daily use

Keep the addresses you pay often in your wallet's address book rather than in a chat thread. A saved entry is one you checked once, in a calm moment, and can reuse without retyping. Chat histories get cleared, forwarded and screenshotted into other hands, so they are a poor place to store anything you rely on.

Treat an address that arrives in a message from someone you do not know as hostile until proven otherwise. Even a familiar contact can have a compromised account, so confirm any change of address through a second channel, such as a phone call to a number you already hold. A request to switch addresses mid-deal is a common trick.

Your recovery phrase is for restoring your wallet, not for receiving coins. Anyone who asks for it in order to send you money is setting a trap. Receiving needs only the address itself; no password, PIN or OTP should ever be typed to accept a payment.

When you move between naira and bitcoin on a platform, the address you use for deposits may differ from the one you give out for sending. Our guide on how to sell bitcoin in Nigeria covers the platform side, including where to find the deposit address and how to check the network before you send.
