Wallet-safe by design. This app reads your wallet address and never requests token approvals or unlimited spending permissions. Paid matchmaking uses a gas-free ownership signature. Score and badge mints send 0 ETH but require network gas. In paid 1v1, your wallet sends only the selected stake to escrow plus gas; rewards are withdrawn separately and failed claims can be retried.
