The navigator.clipboard API requires HTTPS or localhost context and appropriate permissions. Consider checking for clipboard API availability before attempting to use it, as it may not be available in all browser contexts or could be blocked by permissions policies.

const handleCopyAddress = async () => {
const handleCopyAddress = async () => {
if (!navigator.clipboard || typeof navigator.clipboard.writeText !== 'function') {
toast.error('Clipboard API not available in this browser or context.')

}

// Fix 1: Check clipboard API availability
