Telegram-native certificate marketplace for iOS sideloading
iSign is a Telegram mini-app where you buy a slot in a shared Apple Developer certificate, so you can sign apps without running a developer account of your own.
Purchase a slot, register your device through our bot, and receive your .p12 + .mobileprovision signing files. Use them in eSign or Feather to install apps you own or are otherwise entitled to run. Pay with USD (Stripe) or Telegram Stars.
Browse the certificate shop and purchase a slot, or win one in a giveaway. A slot is your key to signing apps.
Send your UDID to our bot. The UDID is the identifier Apple uses to register a device against a developer certificate — without it, a signed app will not run on your phone. Registration usually takes minutes, sometimes up to 3 days.
We store it only to keep your device registered, never share it, and remove it on request — see the Privacy Policy.
Receive your .p12 and .mobileprovision files through the bot. Import them into eSign or Feather.
Open your .ipa in eSign or Feather, select your certificate, and install. Bring your own apps or grab them from community sources.
Browse certificates from faction-based suppliers with transparent pricing, tier ratings (S/A/B/C), and risk levels. Pay with USD or Telegram Stars.
Every certificate shows its supplier, revocation history, and replacement track record. If a supplier breaks a promise — you'll see it before you buy.
Community-curated IPA collection in our Telegram group. New apps added daily from major sideloading channels.

Stable enterprise certificates, supplier for major sideloading platforms.
Premium developer certificates with fast activation.
Rare slots with verified Apple Developer accounts.
Free tier. These certificates are shared widely, so Apple can revoke them at any time — in practice within 60–90 days. Treat a free slot as temporary; a replacement is not guaranteed.
Open the marketplace bot, browse certificates, and register your device. Free slots are available to start with — they are shared and short-lived, so treat them as a trial rather than a guarantee.
