The wrong-network mistake that destroys funds

Who this is for: you're about to send crypto somewhere — an exchange, a wallet, a friend — and you've heard that picking the wrong "network" can lose the money forever. You're right to be careful. This guide explains what a network actually is, the exact ways people get it wrong, and how to check before you press send.

⚠ Why this is different from a normal mistake Sending money to the wrong bank account can usually be traced and sometimes reversed. Crypto sent on the wrong network has no bank, no branch, and no manager to call. In most cases it simply cannot be recovered by anyone — not the exchange, not the wallet maker, not PlainCrypto. That's not a scare tactic, it's just how the technology works.

What "network" actually means

Think of a coin's ticker (like ETH, USDT, or SUI) as a brand name, and the network as the road it travels on. Some coins only ever use one road. Others — usually stablecoins and popular tokens — have been built to travel on several different roads at once, and each road has its own separate address format and separate "post office."

The danger: an address that's perfectly valid on one road can look totally normal and still be the wrong destination on another road. There's no warning light. The transaction goes through, looks successful, and the coins land nowhere you can reach — or nowhere at all.

Real traps to know

Situation	The trap
A token exists as both an ERC-20 (Ethereum-style) version and its own native mainnet coin	Sending the ERC-20 version to a native-mainnet-only address (or vice versa) is one of the most common ways people lose funds. Always confirm which version your destination wallet actually holds.
A coin migrated from an older network (e.g. Cosmos-style) to a newer EVM (Ethereum-style) network	Old and new addresses can look similar but belong to completely different chains. An old-format address is not automatically compatible with the new network, and mixing them up loses funds.
A wallet that supports a coin's ticker but not every network it runs on	Just because your wallet shows "SUI" or "APT" as a coin name elsewhere doesn't mean this specific wallet can receive it — some major hardware wallets simply don't support certain coins at all.
Stablecoins on multiple chains (USDT, USDC, etc.)	The same stablecoin can exist on half a dozen different networks. Sending USDT on the wrong one to an exchange deposit address is a routine way people lose money — always match the network the receiving side explicitly names.

The check-before-you-send checklist

0 of 6 steps done

1.Find out every network this coin actually runs on

Search "[coin name] official networks" or check the project's own website. Many coins run on more than you'd assume — don't guess from memory.

Why: you can't pick the right network if you don't know all the wrong ones exist.

2.Confirm your destination wallet supports this coin on that specific network

Check the wallet maker's own support page — not a forum post, not memory from last year. Support lists change, and some coins are unsupported on certain wallets entirely.

Why: a wallet can show a coin exists "on the app" while still being unable to receive it from a particular network.

3.Open the RECEIVE screen in your wallet and read the network name it shows

Don't assume — read the exact words on screen. If nothing is shown, the wallet usually only supports one network for that coin; confirm which one via the wallet's own documentation.

Why: this is the one source of truth for "which road" your wallet is actually parked on.

4.On the sending side, match the network name exactly — word for word

The withdrawal or send screen will usually offer a dropdown of networks. Pick the one that matches your wallet's receive screen exactly, not the cheapest or the default option.

Why: exchanges often default to whichever network is cheapest for them to process — not whichever one your wallet needs.

5.Run the destination address through a format checker

Use the Address Sanity Checker to confirm the address format matches the network you've selected. It flags several of the exact wrong-network patterns described above.

Why: a second, independent check catches mistakes that "looks about right" doesn't.

6.Send a small test amount first, on this exact route

Before moving the full amount, send a small amount using the exact coin, network, and address you've just verified. Wait until it actually arrives before sending the rest.

Why: this is the final safety net. If everything above was right, the test proves it for a few pounds instead of your whole balance.

🎉 You've checked every angle — that's exactly right.
This is the same routine to run every single time you use a new coin, wallet, or route — even ones you've used before, if anything about the setup has changed.
