Executive Summary

ES Overview

blocfone® — Cryptocurrency-Native Travel eSIM Service

blocfone® is a cryptocurrency-native travel eSIM service that allows global travelers to instantly purchase, activate, and manage data plans using USDC — without contracts, roaming agreements, or identity paperwork. The service is delivered entirely through a Telegram bot and integrated Mini App, requiring only a mobile device and a self-custodied crypto wallet.

The Business

The global travel eSIM market is growing rapidly, driven by smartphone adoption and increasing international travel. blocfone® removes all friction: find a plan, pay with stablecoin, receive your eSIM activation code in the same chat window — in under two minutes. The business model is straightforward: blocfone® earns a margin on each plan sold, priced into the USDC display price. No advertising, no subscription, no PII collection.

The Aspiration

The longer-term vision, codified in US Patent 10,915,873 B2 (issued February 9, 2021), is to eliminate inter-service agreements between mobile service providers and distributors entirely. blocfone’s patented architecture replaces bilateral agreements with a smart contract marketplace — providers post offers directly to a distributed network, a blockchain oracle confirms delivery, and settlement triggers automatically. This positions blocfone® as infrastructure for a decentralised mobile services marketplace with no central clearing house required.

The MVP

The prototype proves the core user flow end-to-end on Solana devnet: a traveler opens the Telegram bot, browses plans, launches the Mini App checkout, deposits USDC into a smart contract escrow, and receives their eSIM activation code — including the QR code, SM-DP+ server address, and activation token — all without leaving Telegram. The stack is production-grade: Node.js on Railway, Telegraf v4, Anchor-based Solana escrow, PostgreSQL with HMAC-hashed subscriber IDs, oracle settlement, and 8-language internationalisation.

The Longer-Term Plan

Phase 1 — Done

Working MVP on Solana devnet — bot, Mini App checkout, escrow, static eSIM demo, order history, 8 languages.

Phase 2 — Next

Affiliate API integration (Airalo, Holafly, or similar) — live eSIM provisioning replaces the static demo. The bot becomes a real product.

Phase 3 — Patent

Multi-provider smart offer marketplace, private sidechain settlement, oracle delivery confirmation, provider portal, subscriber identity layer. Full realisation of granted patents: US 10,915,873 B2 / EU EP3542333A1.

blocfone® + Agentic AI = Genuine, Real-Time, Open Marketplace for Mobile Subscribers & Providers — Without Intermediaries!

A patented, neutral marketplace where smart contracts enforce service terms, crypto settles payments, and Agentic AI runs operations — end to end.

Core Concept & Market Size The Marketplace, The Operator, The Opportunity

blocfone® is a patented, real-time, neutral, and open marketplace where mobile subscribers experience uncomplicated connectivity with participating mobile providers, by paying in cryptocurrency (e.g., stablecoin), and having service terms enforced automatically by smart contracts. In return, mobile providers boost customer loyalty and expand revenue streams while delivering better customer experiences and driving efficiencies by eliminating multi-carrier agreements.

Agentic AI is the operational layer that makes this run without human intervention at each step — handling provider selection, KYC verification, service monitoring, and settlement autonomously.

The MVP proves the payment and delivery mechanism at small scale on Solana devnet; the patent removes the need for bilateral carrier agreements at any scale. Today a Telegram-first travel eSIM niche; tomorrow infrastructure for every mobile subscriber on earth.

There are 8.83 billion global mobile subscriptions which define our Patent TAM — the full market if US 10,915,873 B2 and EU EP3542333A1 are adopted across MNOs and MVNOs worldwide. Patent-protected IP limits our addressable launch markets to the E.U. and U.S. with ~987 million subscriptions, forming our Telegram SAM of ~68M crypto-active users. Our Telegram-First MVP targets crypto-native travelers — capturing just 1% gives us a 612,000-user MVP SOM at launch.

The eSIM market is growing from 40M users in 2024 to over 215M by 2028 (Juniper Research). The stablecoin market exceeded $200B in 2025. Telegram’s wallet infrastructure reaches 800M users. Three converging trends — one product built for exactly this moment.

Where blocfone® Has the Advantage Two Structural Advantages

Two structural advantages that compound: one removes the need for carrier agreements entirely, the other makes the whole model legally defensible.

Structural Advantage No Pre-Existing Carrier Relationships Required

The standard blockchain or agentic AI model still assumes underlying commercial relationships exist between providers and platforms. The blocfone® patent eliminates that dependency entirely. Any provider that meets technical and KYC compliance standards can participate instantly — no bilateral agreements, no negotiation, no legal overhead.

The AI agent doesn’t negotiate — it executes. This makes the marketplace self-expanding: more providers join because the barrier is technical compliance, not a legal agreement with every other carrier on earth. A global bank that wants to offer mobile connectivity across multiple carriers — boosting loyalty and opening a new revenue stream — can now do exactly that, without a carrier deal on the table. That is a genuinely different architecture from anything currently operating in telecoms.

IP Advantage Patent-Protected — Defensible, Enforceable, Granted

US Patent 10,915,873 B2 and EU EP3542333A1 are granted — not pending, not applied for. Any acquirer or licensee steps into a legally defensible first-mover position with enforceable IP across the two largest developed-market jurisdictions.

The Telegram MVP proves the payment and delivery mechanism works today. The patent makes the full vision defensible at any scale. One protects the technology; the other proves it runs.

Architecture Components

Three layers, one marketplace: smart contracts as the carrier agreement, Agentic AI as the network operator, and oracles as the signal layer that keeps everyone honest.

Smart Contracts

Smart Contracts as the Carrier Agreement

Every service session, or roaming session that would previously require a negotiated inter-carrier agreement, is instead defined as a smart contract: service type (voice / data / SMS), rate, duration, coverage zone, and performance expectations.
Contracts hold subscriber cryptocurrency in escrow and release payment to the provider only when service delivery is verified.
No carrier commercial relationship is needed in advance — the contract is the agreement.

Agentic AI

Agentic AI as the Network Operator

The AI agent continuously scans available providers at the subscriber’s physical location, ranks them by price and coverage quality, and presents or automatically selects the best option in real time.
Sub-agents handle parallel tasks: one monitors live call / data quality metrics, one watches for service degradation, one manages KYC state, and one handles payment conversion via sidechain.
The agent acts on behalf of the subscriber without requiring them to understand the underlying marketplace mechanics.

Oracles

Oracles as the Signal Layer

Coverage data, signal quality, and network performance metrics are fed on-chain via oracles so smart contracts can verify that the provider is actually delivering what was agreed.
Location data triggers the marketplace query. When a subscriber moves into a new coverage zone, the agent automatically re-evaluates available providers.
Stablecoin price feeds ensure accurate fiat-equivalent billing regardless of crypto market movement.

How It Works in Practice

Four steps, start to finish: onboarding, provider selection, service monitoring, and payment settlement — all driven by the agent, all enforced by the smart contract.

Onboarding

Subscriber Onboarding & KYC

The AI agent runs the subscriber through KYC verification once, on first registration.
That verified identity is stored on-chain and travels with the subscriber across every provider they connect through. No re-verification needed when switching networks (assuming jurisdictional data elements are added upon first registration) — the technical foundation for blocfone’s number portability model.

Provider Selection

Real-Time Provider Selection

Subscriber arrives in a new location. The agent queries available providers in that coverage area, retrieves their current pricing and service terms, ranks options, and either auto-selects or presents a ranked list.
This happens in seconds and offers genuine subscriber choice — replacing what currently automatically binds subscribers via roaming negotiation between carriers.

Monitoring

Service Delivery Monitoring

Once a provider is selected and the smart contract is activated, the AI agent monitors the session: call quality, data throughput, latency, uptime.
If service drops below the contracted threshold, the agent logs the breach on-chain, pauses or adjusts payment, and either switches the subscriber to an alternative provider or initiates a partial refund — all without human intervention.

Settlement

Payment & Settlement

Subscriber pays in cryptocurrency (any stablecoin or crypto) directly to the smart contract.
On verified session completion, the contract releases payment to the provider.
The sidechain handles real-time fiat conversion where needed — removing currency friction for both subscribers and providers globally.
