Self-Custody Security Guide

How Much Do You Really Know About Cold-Wallet Security?

Cold wallets can help protect private keys. But security also depends on what happens when you browse, connect, sign, approve, and transfer.

01 · Keys & Backup

Your private key is only one part of the picture.

A hardware wallet can keep signing keys in a controlled environment. Your recovery phrase is still critical: anyone who obtains it may be able to control the associated assets.

Never share a recovery phrase or private key with a website, support agent, or another person.

02 · Websites & DApps

Check where you are connecting.

A familiar-looking page is not proof that a site is legitimate. Before connecting, check the domain, source, and purpose of the DApp.

Verify the website first. Connect only when you understand what the connection is for.

03 · Signatures & Approvals

Read what you are actually confirming.

A signature or approval can authorize an action. Do not blindly confirm an unfamiliar request simply because it appears inside your wallet.

Understand the request before you sign or approve it.

04 · USDT Transfers

Before sending, verify the basics.

NetworkConfirm the sending and receiving networks are compatible.

AddressReview the complete destination address, not just a few characters.

AmountConfirm the amount before the final approval.

FeesCheck the expected network or transaction fee.

A few seconds of verification can prevent an avoidable transfer mistake.

Common USDT Networks

USDT can exist on different networks.

Examples include TRON (TRC-20), Ethereum (ERC-20), and BNB Smart Chain (BEP-20). The network selected for a transfer matters. Always verify that the receiving side supports the same network before sending.

Complete Checklist

Before your next important action

I know where my recovery phrase is stored and have not shared it. I verified the website or DApp source and domain. I understand the signature or approval I am about to confirm. I checked the complete destination address. I confirmed the network is supported on both sides. I checked the amount and expected fees.

Security is more than the hardware.

When using self-custody wallets, take a moment to verify the site, request, network, address, amount, and authorization before confirming an important action.
