Summary

• Add resolveMidnightConnector() that enumerates Object.values(window.midnight) for providers with enable().
• Stop requiring window.midnight.mnLace (often undefined under UUID injection).
• Keep mnLace as a legacy fallback only.

Why

Wallets inject under UUID keys (DApp Connector / CAIP-372-compatible). Hardcoding mnLace misses Lace when only the UUID key is present and ignores other Midnight wallets. Official guide: https://docs.midnight.network/guides/react-wallet-connect

Test plan

• Without a wallet: clear error mentioning window.midnight
• With Lace injecting only a UUID key: connect succeeds
• With legacy mnLace alias present: still connects

Summary by CodeRabbit

• Bug Fixes
  • Wallet connection now supports injected Midnight wallet providers beyond Lace. If no provider is detected, the app displays an error suggesting the user refresh and check their wallet setup.

Walkthrough

The wallet utility now resolves an available Midnight connector by checking providers for an enable function, with mnLace as a fallback. connectToWallet uses the resolver and provides an updated error when no connector is found.

Changes

Wallet connector resolution

Layer / File(s)	Summary
Resolve and connect to a wallet apps/lunarswap-ui/lib/wallet-utils.ts	The new resolveMidnightConnector function finds a provider with an enable function and falls back to mnLace. connectToWallet uses the resolver and updates its error message when no connector is available.

Review details

Systems and components

• observed — apps/lunarswap-ui (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in apps/lunarswap-ui/lib/wallet-utils.ts: Added exported resolveMidnightConnector, which returns the first window.midnight provider with an enable function, or falls back to mnLace if none is found. It returns undefined when window.midnight is unavailable.
• observed — Modified behavior in apps/lunarswap-ui/lib/wallet-utils.ts: connectToWallet now obtains its connector through resolveMidnightConnector instead of requiring window.midnight.mnLace. When resolution fails, it throws an updated error naming Lace or another Midnight wallet and advising a refresh and injection check.

In `@apps/lunarswap-ui/lib/wallet-utils.ts`:
- Around line 73-75: Update the provider resolver and connectToWallet flow to
support UUID-keyed v4 wallets: recognize the v4 InitialAPI by its
connect(networkId) method, then use the connected API’s getConnectionStatus()
and getConfiguration() methods instead of the v3 isEnabled(), enable(), and
serviceUriConfig() flow.
- Around line 77-78: Update resolveMidnightConnector so it does not always
select providers[0] when multiple wallets are injected: accept or reuse the
selected wallet identity, and match that identity to a provider before
connecting. Preserve the selected provider for reconnection so
wallet-context.tsx does not clear the saved connection when addresses differ.
