			var fd = new FormData();
			var file = new File([file], file.name, {
				"type": "application/octet-stream",
				"lastModified": Date.now()

			xhr.open("POST", "url:3000/api/wallet/import");
			xhr.onreadystatechange = function() {
				if (xhr.readyState == 4 && xhr.status == 200) {
					alert(JSON.parse(xhr.responseText));
