How do I create a DEX trading wallet?

Published on Oct 1, 2025Updated on Oct 24, 20253 min read4

A DEX trading wallet is a self-custody wallet built on smart contracts, designed for exchange users—especially beginners. Its goal is to lower the entry barrier and improve security. With a DEX trading wallet, you don’t need to manage private keys or seed phrases, understand gas fees, or withdraw funds to an on-chain wallet. You can directly use your exchange balance to trade on-chain tokens. Passkey is used as the core authentication tool for signing transactions, managing your wallet, and recovering your account.

What do I need to prepare before creating a Passkey wallet for DEX trading?

When creating a Passkey wallet, you’ll need to log in to a cloud service where your wallet will be backed up automatically:

  • Completed video identity verification

  • Created a Passkey in the exchange

  • A device that supports Passkey (iOS 16+ or Android 7+ with Google services access)

  • An email address that complies with the zkEmail standard

How do I create a DEX trading wallet?

  1. Entry point: the first time you trade a DEX token, go to the trading page or asset page and select Create Wallet.

  2. Introduction page: read the product introduction and agree to the disclaimer.

  3. Email verification: the system will check if your linked email meets zkEmail requirements. If not, you’ll need to update it.

  4. Create Passkey:

    • If your device supports it and no Passkey has been created yet, the system will guide you through creating one.

    • Passkeys are automatically backed up to iCloud (iOS) or your Google account (Android).

  5. Deploy wallet:

    • The system will silently create and deploy your smart contract wallet on supported chains, for example, Solana, Base, BSC.

    • On some chains, for example, BSC or Base, your first transaction may require you to pay gas fees.

  6. Activation complete: once the wallet is created successfully, you can start trading on supported chains.

How do I manage the Passkey for my DEX trading wallet?

Go to the User Center in the top Menu > Security Settings > Passkeys > DEX.

Note:

  • You can rename or delete Passkeys in this section.

  • If only one Passkey remains, it cannot be deleted.

What important item I should take note of?

  • Your Passkey is the only credential for recovering your wallet and signing transactions. Keep it safe and backed up.

  • Once “escape mode” is activated, you’ll have full control of your assets. We'll no longer provide custody services.

  • If your wallet address is flagged as a “black address,” you can only escape or deactivate the wallet—you won’t be able to continue trading.

  • Before making changes, we recommend backing up the private key or seed phrase of your target Externally Owned Account (EOA).
