Mobile users in a normal browser hit "no wallet found" because EIP-6963 only sees injected/extension wallets. WalletConnect fixes it: the connect picker now offers WalletConnect (auto-selected when no injected wallet is present), which shows a QR on desktop and opens the wallet app directly on mobile — no in-app dApp browser, no second login. Lazy-loads the @walletconnect/ethereum-provider UMD from jsdelivr; the result is a plain EIP-1193 provider so sign/switch/buy are unchanged. CSP widened for the SDK + WC relay. Project id lives in site config (public value); gated so nothing changes until it's set. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
