+# Wallet No Account Message — Quick Fix
+
+## Bug
+When a wallet provider was detected but returned no account, the wallet login UI displayed the raw internal error key `walletNoAccount`.
+
+## Root Cause
+`connectInjectedWallet` throws `Error("walletNoAccount")`, but the modal and toast paths rendered `error.message` directly. The locale dictionaries also did not define a friendly `walletNoAccount` message.
+
+## Fix
+Translate wallet error keys before rendering them, and add user-facing English and Simplified Chinese text for `walletNoAccount`.
+
+### Files Modified
+- `src/wallet/WalletLoginModal.tsx` — translate wallet error messages before showing modal errors.
+- `src/wallet/WalletProvider.tsx` — translate wallet error messages before showing toast errors.
+- `src/locales/en.ts` — added English `walletNoAccount` copy.
+- `src/locales/zh-CN.ts` — added Simplified Chinese `walletNoAccount` copy.
+
+## Verification
+- `npx tsc --noEmit`
+- `npm run format:check`
+- `npm test`
+
+## Notes
+The underlying login behavior is unchanged. This only replaces the raw internal key with a user-friendly explanation to unlock/select a wallet account and retry.
