As the BitPay protocol is used only on BitCoin, this article applies only when attempting to send BTC from your TenX BTC wallet to a BitPay generated QRCode or URL.
This feature is currently under review - for now, attempting to use a BitPay QR code (or a BitPay URL) as a send target will result in an "Invalid Address" error.
BitPay uses the Payment Protocol, which hides the address behind a URL. This address is not a direct target to a wallet address. The TenX Wallet does not support interpreting indirect methods such as this.
If possible, please retrieve a direct and valid BTC wallet address to use as a send target.
