Sending crypto on the wrong network means your money disappears into an address that cannot access it

When you send cryptocurrency, the network you choose determines where your coins actually go. Bitcoin lives on the Bitcoin network. Ethereum lives on the Ethereum network. Polygon, Arbitrum, Optimism, and Solana are separate networks too. If you send Bitcoin to an Ethereum address, or Ethereum to a Polygon address, your transaction will fail or your coins will land in an address controlled by nobody — and you cannot get them back.

The mistake happens because many cryptocurrencies use the same address format. An Ethereum address and a Polygon address look identical: both start with 0x and contain 40 hexadecimal characters. Your wallet or exchange will not stop you from sending to the wrong network if the address format matches. You have to check the network yourself before you hit send.

Key Takeaways

  • Different networks (Bitcoin, Ethereum, Polygon, Solana, Arbitrum) are separate systems, and sending coins to the wrong network means permanent loss.
  • Check the receiving address's network before sending by asking the recipient, looking at their wallet settings, or checking the blockchain explorer for that specific network.
  • Your wallet or exchange shows which network you are sending on — look for a dropdown menu or network selector before you confirm the transaction.
  • If you send to the wrong network, the transaction cannot be reversed; coins sent to an address on the wrong network are lost.
  • Stablecoins like USDC and USDT exist on multiple networks, so you must match both the coin and the network when sending.

How to identify which network an address belongs to

The safest way is to ask the person or service receiving the money which network they want it on. If you are sending to a friend, ask them directly. If you are sending to an exchange or service, check their deposit instructions — they will list the network name and often show you a sample address.

If you have the address but not the network, you can search it on a blockchain explorer to see which network it belongs to. Go to Etherscan.io for Ethereum addresses, Polygonscan.com for Polygon, Arbiscan.io for Arbitrum, or Solscan.io for Solana. Paste the address into the search box. If the address exists on that network, the explorer will show you its transaction history. If it does not exist, try a different explorer.

You can also check your recipient's wallet settings directly. Most wallets show you which networks they support and which addresses belong to which network. MetaMask, Phantom, Coinbase Wallet, and Trust Wallet all display the active network at the top of the screen or in a dropdown menu.

Checking the network before you send

Before you confirm any transaction, your wallet or exchange will show you which network you are sending on. Look for a label that says "Network", "Chain", or "Blockchain" — it usually appears near the address field or in a dropdown menu.

In MetaMask, the network name appears at the top of the window. Click it to see a list of networks you can switch to. In Coinbase, when you go to send, a dropdown shows which network is selected. On Kraken or other exchanges, the deposit or withdrawal page lists the network as part of the receiving address details.

Write down or screenshot the network name before you send. Then double-check it against what the recipient told you. If they said "send on Polygon" and your wallet shows "Ethereum", stop and switch networks before you proceed. This one-second check prevents permanent loss.

What happens if you send to the wrong network

If you send coins to an address on the wrong network, the transaction will either fail immediately or succeed but land in an inaccessible place. Some wallets and exchanges have safety features that reject the transaction if the network does not match. Others will accept it and send your coins to an address that exists on the wrong network — where nobody can access them.

Once the transaction is confirmed on the blockchain, it cannot be reversed. The coins are gone. There is no customer service team that can retrieve them, no "undo" button, and no way to contact the address owner because the address is not controlled by a person — it is just a string of characters that happens to exist on two different networks.

Some advanced users have recovered coins sent to the wrong network by importing the private key of that address into a wallet that supports the correct network. This only works if you control the address (meaning you own the private key), and it requires technical knowledge. For most people, sending to the wrong network is permanent loss.

Stablecoins and multi-network coins

Stablecoins like USDC, USDT, and DAI exist on multiple networks at the same time. USDC runs on Ethereum, Polygon, Arbitrum, Optimism, Solana, and other networks. Each version is separate. USDC on Ethereum is not the same as USDC on Polygon — they are different tokens on different networks, even though they have the same name and the same value.

When you send a stablecoin, you must specify both the coin and the network. If you send USDC on the Ethereum network to someone who is expecting USDC on Polygon, they will not receive it. Your wallet will show you which network you are sending on, so check it the same way you would for any other coin.

Some exchanges and wallets have bridge tools that let you convert coins from one network to another. These are separate transactions and cost fees. Do not confuse a bridge with a regular send — if you send directly to the wrong network, a bridge cannot help you.

Networks and their common uses

Bitcoin is its own network. There is only one Bitcoin network, so you cannot send Bitcoin to the wrong chain. Bitcoin addresses start with 1, 3, or bc1.

Ethereum is the original smart contract network. Most tokens and services run on Ethereum. Ethereum addresses start with 0x. Ethereum has high transaction fees.

Polygon is a faster, cheaper network that connects to Ethereum. Many people use Polygon for the same tokens and services available on Ethereum, but with lower fees. Polygon addresses also start with 0x.

Arbitrum and Optimism are similar to Polygon — they are faster and cheaper than Ethereum but connected to it. Both use 0x addresses.

Solana is a separate network with its own tokens and services. Solana addresses look different: they are longer and use a different character set. You cannot send Solana tokens to an Ethereum address.

If you are new to crypto, start by asking the person or service you are sending to which network they use. Most services now support multiple networks, so they will tell you which one they prefer.

Common mistakes and how to avoid them

The most common mistake is copying an address from one place and pasting it into a wallet set to a different network. Always check the network dropdown before you paste the address. Some people copy the address first, switch networks, and then paste — by then they have forgotten which network the address was for.

Another mistake is assuming that because an address looks right, it is right. Ethereum and Polygon addresses are identical in format. You cannot tell them apart by looking. You have to check the network setting in your wallet.

A third mistake is sending a test amount first without checking the network. If you are going to send a test transaction, check the network just as carefully as you would for a large amount. A small loss is still a loss.

Finally, do not trust a service or person who tells you the network does not matter. It always matters. If someone says "just send it, the network does not matter," they are either mistaken or trying to scam you.

Frequently Asked Questions

Can I recover coins sent to the wrong network?

Not in most cases. Once a transaction is confirmed, it cannot be reversed. If you sent to an address you do not control, the coins are lost. If you sent to an address you do control (your own wallet on the wrong network), you may be able to recover them by importing the private key into a wallet that supports the correct network — but this requires technical knowledge and is not may provide to work.

What if I send Bitcoin to an Ethereum address?

Bitcoin and Ethereum are completely separate networks. Bitcoin addresses do not work on Ethereum. The transaction will fail, and your Bitcoin will not be sent. Your wallet should reject the transaction before it goes through.

Do I need to pay a fee if I send to the wrong network and the transaction fails?

If the transaction fails before it is confirmed, you may still lose the network fee (called gas) because your wallet had to attempt the transaction. If the transaction succeeds but lands on the wrong network, you lose both the coins and the fee.

How do I know if an exchange supports the network I want to send on?

Go to the exchange's deposit page for the coin you want to send. It will list all the networks that exchange accepts for that coin. If the network you need is not listed, you cannot send directly to that exchange on that network — you would need to use a bridge or send to a different service.

Can I send Ethereum to a Polygon address?

No. Ethereum and Polygon are different networks. If you send Ethereum to a Polygon address, the transaction will fail or the coins will land in an inaccessible place. You must send Ethereum on the Ethereum network and Polygon tokens on the Polygon network.
