## Walkthrough The recent updates primarily focus on optimizing the performance and logic of the QR and WebLN components in the codebase. The `Qr` component has been refined by removing the `useRef` for `sendPayment` and revising the conditional logic in `useEffect`. Additionally, the WebLN provider components (`lnbits`, `lnc`, and `nwc`) have been enhanced by incorporating the `useMemo` hook to memoize context values, thereby reducing unnecessary re-renders and improving overall efficiency. ## Changes | File Path | Change Summary | |------------------------------------------|--------------------------------------------------------------------------------------------------| | `components/qr.js` | Removed `useRef` for `sendPayment` and adjusted `useEffect` conditional logic. | | `components/webln/lnbits.js` | Added `useMemo` for value memoization and removed `name` declaration. | | `components/webln/lnc.js` | Introduced `useMemo` for context value memoization. | | `components/webln/nwc.js` | Added `useMemo` for context value memoization and removed `name` declaration. |Recent Review Details

`194-196`: LGTM! Ensure all dependencies for `useMemo` are correctly listed to avoid stale data issues.Verification successful
--- The `rg` command confirmed the presence of the `useMemo` hook in the file. Let's manually verify the dependencies listed in the `useMemo` hook. Here is the relevant code snippet from `components/webln/lnc.js`: ```javascript const value = useMemo( () => ({ name: 'lnc', status, unlock, getInfo, sendPayment, config, saveConfig, clearConfig }), [status, unlock, getInfo, sendPayment, config, saveConfig, clearConfig] ); ``` The dependencies listed in the `useMemo` hook are: - `status` - `unlock` - `getInfo` - `sendPayment` - `config` - `saveConfig` - `clearConfig` These dependencies match the variables used within the `useMemo` callback. Therefore, all dependencies for `useMemo` are correctly listed.Scripts Executed

Description
This fixes the hack in the QR component to prevent infinite renders if
provider.sendPaymentis called by wrapping the context value withuseMemo.Checklist
