Listing safety, wallet security, and scam prevention.

Direct answer

Cryptocurrency security follows from three properties: transactions are irreversible, private keys are the sole authority over funds, and there is no administrator to appeal to. Prevention is therefore the only control that works. Nearly all real losses come from authorisation mistakes and social engineering — not from broken cryptography.

Start here

The two habits that matter most

Both are structural — they work without requiring you to correctly identify a threat. That matters, because correct identification is exactly what attackers spend their effort defeating.

1. Separate wallets by purpose

A vault that never touches contracts, a trading wallet, and a burner holding almost nothing for anything unfamiliar.

A malicious approval signed from a burner costs you a burner's contents. The identical signature from a vault costs you everything. You will eventually sign something you should not have; this decides what it costs.

2. Always initiate contact yourself

Type domains. Never follow links about your account, never respond to approaches, never reach a financial site from a search result.

This single habit defeats fake support, phishing, listing fraud, and recovery fraud simultaneously — four separate fraud categories, one behaviour.

Where losses actually come from

In rough order of frequency:

1. Authorisation mistakes — a malicious token approval, or a transaction signed without reading it. No key theft; permission was granted.
2. Social engineering — fake support, impersonated staff, urgent opportunities, recovery fraud after an earlier loss.
3. Key handling — a seed phrase stored somewhere convenient and later accessed, or lost with no backup.
4. Wrong destination — right amount, wrong address or wrong network.

Broken cryptography does not appear. Defensive effort belongs where the losses are.

The rule with no exceptions

No legitimate service ever needs your seed phrase.

Not support, not an administrator, not a verification tool, not a migration process, not CoinDock. A seed phrase grants complete control of a wallet, so anyone asking for it is attempting theft. There is no scenario in which providing it helps you.

What CoinDock will never do

• Ask for your seed phrase or private keys.
• Contact you first requesting a payment, an approval, or a credential.
• Send an invoice as an address in a message — invoices appear in your authenticated account.
• Guarantee a price, a return, or a performance outcome.

If something claiming to be CoinDock does any of these, it is not CoinDock. Report it via coindock.online/about, reached by typing the domain.

Account controls CoinDock provides

Two-factor authentication and passkeys (which cannot be phished, being bound to the domain), email verification, password confirmation before security changes, trusted-device management, scoped API keys separating read, trade, and withdraw, and a withdrawal address allowlist with a cooldown — so momentary account access cannot be turned straight into a withdrawal.

Details in account protection.

Note the boundary: these protect your CoinDock account. They have no bearing on a self-custody wallet.
