Sending crypto and stablecoins safely: networks, addresses and the information that travels with your transfer

Sending crypto to a wallet is quick. Getting it wrong can be permanent. A card payment can sometimes be disputed, but a confirmed blockchain transfer generally cannot be reversed. Circle's overview of stablecoin payments puts it plainly: once a transaction is confirmed and finalised, there are no chargebacks or reversed payments.

This guide covers the checks that prevent the most common and costly mistakes.

1. Choose the right network

Many crypto-assets, especially stablecoins, exist on more than one blockchain network. The same stablecoin can be issued on several networks, and each version only works on its own network.

Before you send:

• Confirm which network the receiving wallet or platform supports for that specific asset.
• Select the same network when you withdraw.
• Do not assume that because two addresses look similar, the networks are compatible.

Sending to an address on a network the recipient does not support is one of the most common ways to lose funds.

2. Check the address, and check it again

Crypto addresses are long strings that are easy to get wrong and hard to read.

• Copy and paste; never type an address by hand.
• Compare the first and last several characters with the source after pasting. Some malware swaps a copied address for the attacker's address.
• Use saved, verified addresses for wallets you send to regularly.
• Be careful with addresses sent by message or email, especially if they arrive with a sense of urgency.

3. Send a small test first

For a new address or a large amount, send a small test transfer and confirm it arrived before sending the rest. It costs an extra network fee but can save the whole amount.

4. Understand fees and confirmation

Each network charges its own fee for a transfer, and fees can change with network demand. A transfer is usually considered final after the network confirms it. Your provider's withdrawal screen should show you the network fee and any provider fee before you confirm.

5. Expect questions about the recipient

You may be asked who owns the wallet you are sending to and whether it is your own. This is not an obstacle; it is the law in many places. On a public blockchain, a wallet is identified only by its address. The Bank for International Settlements noted in June 2025 that this pseudonymity can protect privacy but also makes illicit use easier. The rules below are meant to close that gap. The Financial Action Task Force applies the "Travel Rule" to crypto transfers between providers, so information about the sender and recipient travels with the transfer. In the EU, Regulation (EU) 2023/1113 and the European Banking Authority's guidelines, which apply from 30 December 2024, require crypto-asset service providers to collect this information. They also set out how to identify and verify the person behind a transfer to or from a self-hosted wallet.

In practice, you may be asked:

• whether the destination is a wallet you control or one held at another provider;
• the name of the wallet owner;
• in some cases, to prove that you control a self-hosted wallet.

Providing accurate answers helps your transfer go through without delay.

6. Be honest about the purpose

If you are sending crypto because someone told you to, for example to "secure" your funds, claim a prize, unlock a withdrawal or join an investment, stop and read our guide to crypto scams first. Legitimate providers and authorities do not ask you to move funds to a new wallet for safety.
