YOUR ETHEREUM WALLET / BASE

SAME WALLET.
A NEW RIVAL.

Use your existing Ethereum wallet on Base. Stakes use native USDC; keep some ETH on Base for network fees.

Funds still on Ethereum? The arena explains how to bridge ETH to Base and swap part for USDC in your wallet. Switching networks alone does not move funds.

Start free. Free play and game credits need no wallet.

OPEN USDC ARENA
How do USDC stakes work?

Both players deposit the same amount of native USDC on Base, from 1 to 500 USDC each. The platform fee is 5% of the total pot up to 50 USDC, then 10% above 50. The winner withdraws the remainder after confirming settlement. For example, 5 USDC each makes a 10 USDC pot: 9.50 USDC to the winner, a net gain of 4.50 USDC. Network fees are separate. Refunds have no platform fee. Real stakes are available only against another player.

Do I need a wallet or an account?

Free play and game credits need no wallet. Choose your name when you enter, or continue as a guest. PROFILE offers optional wallet sign-in to recover your account on another device. Connecting alone does not sign you in or transfer funds. USDC duels require a wallet on Base.

Are game credits real money?

No. Game credits are practice points with no cash value. They cannot be purchased, sold or withdrawn, and there is no promised automatic conversion into a future token. Free play and game credits need no wallet.

Can mobile players face PC players?

Yes. Open Free Play, choose Online and share your room’s invite link or code. PC and mobile fighters can face each other over the internet. Quick Match can also find an opponent.
