Connect your wallet

Option A — Email

1. Click Connect, enter your email, and press Submit.

2. A 6-digit verification code arrives in your inbox within seconds. Enter it to log in.

3. Privy automatically creates a blockchain address tied to your email. You'll deposit USDC to this address.

4. Click Enable Trading and sign the gas-less transaction in the popup.

Option B — EVM wallet (MetaMask, Rabby, etc.)

1. Click Connect and choose your wallet. Approve the connection request in the popup.

3. Send USDC to your address from a CEX or another wallet.

We recommend using a standard Externally Owned Account (EOA) wallet — such as MetaMask or others wallet.

Please do not use AA(Account Abstraction) Wallet. Depositing with an AA (Account Abstraction) wallet will prevent your account from performing subsequent trading or fund withdrawal operations. Your funds may become permanently locked in the platform contract.
