About proof.holdings
We've spent 10+ years building telecom and software infrastructure. We know exactly how broken verification is.
Our Story
LT Telecom (Uždaroji akcinė bendrovė "LT telekomunikacijos") has delivered telecom and software solutions since 2015. We've built infrastructure that handles communication at scale across Europe and beyond.
We built proof.holdings because we were tired of the same problems appearing in every project:
- Phone verification: SMS costs $0.05-$0.40+ per message globally, delivery fails 10-30% internationally, and SIM-swap attacks bypass it entirely
- Domain verification:Vendors send screenshots that could be fabricated in minutes. Hours wasted on "can you show me your DNS?"
- Social proof: Links to profiles prove nothing. Screenshots are trivial to fake. Impersonators cause real damage.
- Wallet verification:"Here's my address" - but whose address? Every OTC trade starts with blind trust.
The Reverse OTP Insight
Traditional verification sends expensive messages TO users. Scammers intercept codes because they initiate the request - they ask for the OTP, then grab it.
Our approach flips it: users send messages TO us. User-initiated verification is inherently more secure - attackers can't intercept what they didn't start. And costs become predictable.
Secure. User-initiated. Affordable. Not just one of the three - all three.
Three Trust Primitives

Verify that someone controls a phone number, email, domain, social account, or wallet. Live today: Telegram/SMS/WhatsApp phone verification, Magic Link/OTP email verification, DNS/HTTP/Auto/Email domain verification.
Proof of Delegation
Authorize AI agents and automations to act on your behalf. Users consent via Telegram or WhatsApp. Live today: consent-based authorization with revocable permissions and cryptographic audit trail.
Proof of Action (HITL)
Human-in-the-loop approvals for AI agents and automation. Humans approve or deny via Telegram or WhatsApp, with cryptographic proof of every decision. Live today: configurable approval channels, timeout with fallback, approve/deny with comments, signed proof tokens.
