Scenario 1: Sent to a valid address you don't own
This is the worst case. If you accidentally sent crypto to someone else's wallet — a valid address that belongs to another person — your only option is to contact them and ask for a refund. If you don't know who owns that address, the funds are gone permanently.
Blockchain transactions are by design irreversible. No exchange, no protocol, and no authority can reverse a confirmed transaction.
Scenario 2: Sent to a non-existent address
Most blockchains use checksums in addresses to catch typos. If you type a random string, it usually won't be accepted as a valid address. But if the checksum happens to validate (unlikely but possible), the crypto is sent to an address nobody controls — effectively burned.
Scenario 3: Sent on the wrong network
This is the most common mistake. You send USDT on the Ethereum network to an address that was expecting it on the Tron network. What happens depends on the recipient:
- If it's an exchange: Many exchanges can recover cross-chain deposits, but it usually takes days/weeks and may involve a recovery fee. Some exchanges don't offer recovery at all.
- If it's a personal wallet: If you control the same address on the other chain (which is common for EVM-compatible chains like Ethereum, BSC, and Polygon), you can often import your private key on the correct chain to access the funds.
- If it's a non-compatible chain: Sending Ethereum-format tokens to a Solana address (or vice versa) typically results in permanent loss.
Scenario 4: Forgot the memo/tag
Some blockchains (XRP, ATOM, XLM) use shared addresses with memo/destination tags to identify individual users. If you send to an exchange without the correct memo, the exchange receives the funds but can't credit them to your account automatically.
Recovery is usually possible by contacting support with proof of the transaction, but it can take weeks.
Scenario 5: Sent to a smart contract
Sending tokens directly to a smart contract address (instead of a wallet) can lock the funds permanently if the contract has no withdrawal function. Some contracts do — most don't. This is irreversible.
Prevention is the only real protection
- Always double-check the first 4 and last 4 characters of the address
- Send a small test transaction first
- Confirm the correct network with the recipient
- Never manually type an address — copy and paste
- Verify the pasted address (clipboard malware exists)
Why demo trading helps
On Korvex, there are no wallet addresses, no network selection, and no irreversible send mistakes. You learn the trading fundamentals — orders, fees, portfolio management — in an environment where the only mistake you can make is a bad trade, not a lost transaction. That foundation matters before you start moving real assets.
