Mobile tips

  • Use MetaMask in-app browser (open this site from MetaMask mobile) or desktop with the extension.
  • Production URL must be HTTPS for wallet connect on phones.
  • Local dev on a phone needs HTTPS (e.g. ngrok); plain LAN IP often fails.
  • After connect: approve → small test buy on an active market.
