Telegram-native certificate marketplace for iOS sideloading
iSign is a Telegram mini-app where you buy Apple Developer certificate slots — without paying $99/year for a full account.
Purchase a slot, link your device UDID through our bot, and receive your .p12 + .mobileprovision signing files. Use them in eSign or Feather to install any app. 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. Apple registers your device — usually takes minutes, sometimes up to 3 days.
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.
