THE PAIN · IF YOU’RE IN CRYPTO

Your Telegram number is the soft target.

Your wallet has a seed phrase. Your exchange has 2FA. But the number on your Telegram connects them all to you, and to everyone who trusts you.

01 It leaks from every group and checkout Every Telegram group, exchange sign-up and online checkout is another place your number can be scraped, sold or breached.
02 One SIM swap from your exchange It receives your 2FA and recovery codes. Take over the number and an attacker can go after your exchange and the email behind it.
03 Then your account turns on your friends A hijacked Telegram looks exactly like you. Same groups, same history. “You” ask friends to send crypto to a new wallet, and they do.
THE BLAST RADIUS One hijacked account. Every chat it’s in. Attackers don’t stop at your wallet. Your trust is the asset: every friend, group and deal you’re part of becomes a target, and the first warning usually comes too late.

THE PROBLEM

Your phone number is doing two jobs at once.

It’s the key that unlocks your money and identity. It’s also the contact you hand out every day. Those two jobs should never share a number.

JOB 1 · THE KEY It unlocks your assets Your bank, exchanges and accounts send login and recovery codes to it. Whoever controls your number can reach:
  • 2FA and login codes
  • Bank and card accounts
  • Crypto exchanges
  • Email and account recovery
  • Healthcare, tax and government
  • Pensions and insurance
JOB 2 · THE CONTACT It’s handed to everyone Every app, shop and group that asks for a number gets the same one, and stores it, shares it or leaks it:
  • Telegram and crypto groups
  • Socials
  • Online shops and checkouts
  • Marketers and data brokers
  • Recruiters
  • Delivery apps
Hover one to see what it can reach

Everyone in Job 2 is one step away from everything in Job 1.

And attackers increasingly use automated AI agents to find that step: scraping groups, matching leaks and calling carriers at scale.

THE PROMISE

Mobias puts a firewall between your assets and the agentic internet.

The internet gets your alias. Your real number stays behind the firewall, known only to your bank, exchanges and 2FA.

  • One persistent alias. Not a burner that gets recycled.
  • You move each account yourself. Mobias never logs in for you.
  • An agent watches your alias and flags changes.

You already use different emails for different audiences. Your number deserves the same.

PLUS

If you’re hacked, the people who trust you hear it from us.

Report a compromise and Mobias warns everyone you’ve linked with, so “you” can’t talk them into sending money. When they’re hacked, you’re warned too.

FAQ

Questions.

01Why not a burner or a second SIM?

Burners lapse and get recycled to someone else, along with your login codes. A second SIM is another plan and still just a number. Mobias is one persistent alias, plus an agent and a trust network.

02Does Mobias read my messages or contacts?

No. No stored messages, no contact upload, no copy of your Telegram session. We hold only the account and alias data the service needs.

03Do I have to move everything at once?

No. You choose what moves and change each number yourself, starting with Telegram.

04Does it work in my country?

We only list countries we’ve tested, and we confirm yours before you pay or move anything.

05What does it cost?

The alias and agent are $10/month or $99/year at launch. The trust network is free. Nothing to pay during early access.
