How to Send and Receive Crypto Transactions Without Losing Funds

Receiving: make yourself hard to mis-pay

1. When someone sends you crypto, share the correct public address for the correct network. Ethereum-looking 0x addresses exist on many chains—specify “ETH on Arbitrum” or “USDC on Base,” not just “my USDC address.” If you use ENS, confirm the resolver still points where you expect before publishing it widely.

2. Prefer QR codes generated inside your wallet for in-person receives. For remote receives, paste address into a plaintext channel and ask the sender to read back the first and last four characters. Never ask senders to “verify” by returning funds to a different address a stranger provides—that is a classic scam pattern.

3. Watch your wallet and a block explorer until the transaction leaves the mempool and reaches the confirmation count you trust for that asset’s value. Small amounts may be fine at 1–3 confirmations; large amounts deserve more patience. How pending state works: What Mempools Are and How Transactions Get Validated.

Sending: the pre-flight checklist every time

4. Select asset and network explicitly. Sending USDT on the wrong chain to an exchange deposit address is one of the most common permanent losses. If the destination is a CEX, copy the deposit address and memo from the deposit page for that exact coin and network—see How to Buy Crypto on a Centralized Exchange Using Fiat Currency for on-ramp context.

5. Paste the destination address, then compare characters against the source—not against your memory. Hardware wallets that show the address on-device should be verified on the device screen. Send a test amount first whenever the destination is new, the amount is material, or a memo is involved.

6. Review gas fees before confirming. On Ethereum-style chains, ensure you hold enough native token for gas. Fee markets move with congestion—see What Gas Fees Are and Why They Change Based on Network Congestion. If a transaction stalls, do not spam identical sends; learn replacement with the same nonce in How to Adjust Gas Fees and Priority Gas Rules Manually to Speed Up Transactions.

7. Risk: Clipboard malware can swap addresses after you copy. Always re-check the address on screen (and on a hardware device if used) immediately before hitting send. If the UI suddenly shows a different address, abort. Address-poisoning lookalikes are covered in How to Identify and Avoid Common Crypto Phishing and Wallet Scams.

8. Save the transaction hash. Look it up on the appropriate block explorer. Pending means not yet included; failed/reverted means gas may be spent but value not transferred; success means state updated. Learn the UI in How to Read a Blockchain Explorer to Track Pending and Completed Transactions.

9. If you sent to the wrong address you control on another wallet, you may recover by unlocking that wallet. If you sent to an irreversible wrong address or wrong chain with no recovery path, assume the funds are lost—support cannot reverse decentralized transfers.

10. Log every material transfer for taxes and your own sanity: date, asset, amount, from, to, network, txid, purpose. Habit stacks with How to Calculate Capital Gains and Prepare Crypto Taxes. Discipline beats speed—especially when moving size between hot wallets and cold storage.
