The seed phrase is the root of your whole security model
In a self-custody wallet whoever holds the seed phrase owns the assets. Neither support nor community admins can restore it, and that has to be accepted upfront.
The OKX Web3 wallet connects on-chain activity with your exchange balance, which is convenient and demands stricter approval habits.
What to prepare before you start
These five things cover almost every delay people run into: Paper and a safe place for writing the seed phrase.
Acceptance that anyone asking for it is scamming you. Knowledge of where to review and revoke contract approvals.
Optionally a clean device dedicated to wallet activity.
Bringing self-custody risk under control
Six habits worth more than any tool: Write the seed phrase on paper - no screenshots, no cloud storage, no chats.
Keep only what you are prepared to self-custody inside the wallet. Read contract address and permission scope before approving.
Revoke unused contract approvals on a schedule. Never open links promising airdrops or wallet repairs.
Spread large balances across wallets or use hardware.
Fees, limits and processing times
Numbers change from time to time, always confirm on the official fee page before you commit size: Set a separate fund password alongside Google Authenticator, then enable the anti-phishing code and address whitelisting.
Review login devices regularly and expect extra checks after changing SIM, email or device. Spot, margin, perpetual and dated futures, plus options, sit at the core of the platform.
Strategy tools such as grid and DCA bots, copy trading, OKX Wallet with its DEX aggregator, and Earn products extend well beyond simple trading. The help centre and in-app support cover most issues; for fund-related cases open a ticket and keep the reference number.
Nobody from real support will ask for your password, 2FA code or seed phrase - treat anyone who does as a scammer.
The OKX-specific part
OKX Wallet is a multi-chain self-custody tool bundled with a DEX aggregator. Watch price impact and slippage settings when using aggregation to avoid nasty fills.
Frequently asked questions
What if I lose the seed phrase
Generally unrecoverable. Move funds to a new wallet immediately if you still have access, since this is the core trade-off.
Does revoking approvals cost gas
Yes, on-chain fees apply, which is normal - schedule periodic cleanups.
Can an exchange account replace a wallet
It can, but that is custodial: the platform controls the assets. Different trade-offs entirely.
