What should I check before sending cryptocurrency?

Before sending crypto, verify: 1) You're on a private secure network, 2) The destination address is correct (check first and last 6 characters), 3) The blockchain network matches on both sides, 4) Your hardware wallet firmware is updated, 5) Send a small test transaction first, 6) You're not being pressured or rushed by anyone.

Can I reverse a cryptocurrency transaction?

No. Cryptocurrency transactions are irreversible once confirmed on the blockchain. This is why using a pre-transfer checklist is critical — there is no undo button. Always send a small test transaction first when transferring significant amounts.

What happens if I send crypto on the wrong network?

Sending cryptocurrency on the wrong network (e.g., sending ETH via BEP20 to an ERC20-only address) can result in permanent, irreversible loss of funds. Always verify that the selected network matches on both the sending and receiving wallet.

What is a MEMO or TAG in crypto transfers?

A MEMO (or TAG) is an additional identifier required when sending certain cryptocurrencies like XRP, XLM, or BNB to exchanges. Missing the MEMO can result in permanent loss of funds.

Should I use a hardware wallet for crypto security?

Yes. A hardware (cold) wallet like Tangem or Ledger stores your private keys offline, making them inaccessible to hackers. This is the gold standard for crypto security.

Safety Checklist

Environment Lockdown

PENDING

I am using a private, password-protected network (never public Wi-Fi).

No screen sharing software is active (Zoom, AnyDesk, TeamViewer).

No one can see my screen — physically or via camera.

My device OS and antivirus are updated to the latest version.

I reviewed my browser extensions — no unknown extensions are active.

I cleared my clipboard before copying the destination address.

⚠ Hidden Risk Clipboard malware can silently replace a copied crypto address with the attacker's address. Always clear your clipboard and verify again after pasting.

Address Verification

PENDING

I copied the address directly from the verified recipient (not from old transaction history).

I verified the first 6 and last 6 characters of the address.

The address type matches the asset I'm sending (BTC ≠ ETH ≠ TRX).

I confirmed the address has no extra spaces or hidden characters.

If sending to an exchange — I included the correct MEMO / TAG (required for XRP, XLM, BNB, etc.).

⚠ Hidden Risk A missing MEMO/TAG when depositing to an exchange means permanent loss. Smart contract addresses can also trap funds. Always verify the address type.

Network Confirmation

PENDING

The selected network matches the destination wallet.

I verified network compatibility on both sides — sender AND receiver.

If using a bridge — I confirmed it is official and not a phishing clone.

⚠ Example Sending ETH on BEP20 to an ERC20-only address = possible permanent loss. Wrong network is one of the most common causes of lost crypto.

Cold Wallet Protocol

PENDING

My hardware wallet firmware is official and up to date.

I verified the address on the hardware wallet screen itself — not just the computer screen.

I am NOT typing my seed phrase anywhere on any device.

My seed phrase is stored offline and physically inaccessible during this session.

⚠ Critical Rule No legitimate wallet, exchange, or service will EVER ask for your seed phrase. If anyone asks — it is a scam. Always verify the address on your hardware device screen.

Transaction Structure

PENDING

I am sending a small test transaction first (if the amount is significant).

I double-checked decimal accuracy (0.1 vs 1.0 vs 10.0).

I have enough native tokens for gas fees (ETH for ERC20, BNB for BEP20, etc.).

I reviewed the full transaction details one final time before signing.

Human Factor Check

PENDING

I am not under emotional pressure or being rushed.

If someone requested this transfer — I verified their identity through a separate channel (phone call, in person).

I understand that crypto transactions are irreversible once confirmed.

⚠ Scam Tactic Scammers create urgency — "send now or lose the opportunity." Legitimate transactions can always wait. If you feel rushed, STOP.

Post-Transaction

PENDING

I saved the transaction hash/ID for my records.

I verified the funds arrived in the destination wallet.

I cleared my clipboard again after completing the transfer.
