MeldOptions class

Configuration options for opening Meld.io

All parameters are optional. Meld.io automatically detects user location, language, and preferred currency based on IP geolocation and browser settings for better UX. Only specify options when you need to override the automatic detection:

  • Requires wallet connection (unless walletAddress is provided)
  • Auto-detects location, currency, language, and payment methods
  • Uses connected wallet address unless overridden
