New channel. New Revenue.


Buyers ask an AI assistant, and pay directly inside a chat without going to a website.

blocfone® is a neutral eSIM marketplace where upstream mobile providers offer plans to sell voice, text and data, or data only, directly to subscribers.

Subscribers compare plans based on device location (or selected location) and price, combined with provider coverage availability, duration, minutes, texts and data usage requested. No contracts.

What’s different?

Upstream Mobile Network Operators (MNOs) can safely offer a full suite of voice, text and data plans direct to subscribers in addition to direct sales channels, and without relying on downstream aggregate reseller Mobile Virtual Network Operators (MVNOs) nor brick-and-mortar retail partners.
MNOs can be assured of blocfone® platform neutrality based on its patented architecture that takes no position among providers, building subscriber trust with transparency and avoiding pricing confusion by aggregating information from disparate channels.
A permanent record of every sale will persist on-chain, independently checkable in real time to verify price integrity, legitimate chargebacks, top-ups, and platform fees.
Automatic on-chain payments to the MNO, settled in stablecoin USDC instantly, and trackable back to every eSIM and top-up purchase.
Reduced (if not elimination of) potentially unfounded credit card chargebacks due to the patented process of confirming eSIM delivery, otherwise an automatic refund; no loss of eSIM in the process.
And a great subscriber experience to quickly and easily buy the eSIM they need, where they need it, and when they need it.

The Essentials

How It Works

Four steps, from listing to settlement.

1

Post

  • Submit your offers — service type, price, allowance, duration, coverage zone. Your terms, your pricing.
2

Match

  • Subscribers are shown offers based on their location and the coverage available there. You compete on price and quality, not alliance membership.
3

Deliver

  • The subscriber accepts and their payment is held. You provision directly to the device — blocfone® is never in your data path.
4

Get paid

  • On verified delivery, settlement releases to you automatically in USDC. If delivery fails, the subscriber is refunded and you carry no dispute.

Zero legal overhead

No Carrier Agreements

The contract is the agreement.

Every session that would normally require a negotiated inter-carrier agreement is instead defined as a smart contract: service type, rate, duration, coverage zone, performance expectations.

No commercial relationship is needed in advance. Any provider meeting technical and compliance standards can participate immediately — direct (MNO) or indirect (MVNO, bank, airline loyalty programme).

Settlement certainty

Paid on Delivery

No invoicing. No collections. No credit risk.

Subscriber funds are committed before you provision. Delivery is verified on-chain by oracle. Settlement triggers automatically on confirmation.

You are never chasing payment, and you never absorb the cost of a failed delivery — the refund path is automatic and separate from you.

Neutral by design

Compete on Your Own Terms

No favoured partners. No preferential routing.

blocfone® takes no position between providers. Offers are ranked for subscribers by price and coverage quality — the marketplace executes, it doesn’t negotiate.

Your pricing stays yours. Change your offers anytime, add coverage zones, or withdraw them — without renegotiating anything with anyone.

Direct to subscriber

New Reach, New Revenue

Reach subscribers you can’t reach today.

Sell into demand that bilateral agreements have never made available to you — travellers in your coverage area, subscribers of carriers you have no relationship with, and buyers who would otherwise go offline entirely.

Built out, the same platform enables number portability, widening the addressable subscriber base from crypto-native travellers to mainstream mobile users worldwide.

Your next million subscribers already have a wallet. They pay in seconds today — and arrive identity-verified tomorrow.

🔒 Your price reaches the buyer exactly as you set it

Post your own retail prices — the same ones on your site. You sign every offer; the chain refuses to publish anything you didn’t sign, and the buyer’s device verifies your price against your signature before purchase, checked against a public node blocfone doesn’t operate. In live testing, an altered card was caught and rejected. When buyers are cross-checking a dozen tariffs at once, one honest number wins more often than a clever one.

🤖 Built for the way people shop now

Buyers no longer read tariff tables — they ask an assistant to compare for them. blocfone speaks that language natively: structured, signed, machine-readable offers an agent can weigh in milliseconds. Your service shows up where the decision is actually being made, instead of behind a landing page nobody visits.

📡 Your offers surface only where you actually cover

Buyers are matched by real device location and the coverage genuinely available there. Your service appears where you can deliver it and nowhere else — no impressions outside your footprint, no sales into gaps, no refunds for coverage you never had.

🔗 No integration with anyone else’s systems

Nothing passes between your systems and another provider’s to fulfil a sale. No competitor sees your traffic, no dependency on a third party’s uptime, no shared middleware to certify against. You connect once, to the platform, and to nobody else.

⚖️ Neutrality you can verify, not a promise you have to trust

One published platform rate, stamped into every order at purchase and emitted at settlement. If it changes for one provider, it changes for all. No most-favoured-nation clause to negotiate, no audit right to request.

🤝 A channel that extends your business, not one that undercuts it

Because you post your own retail prices, you never compete with your own site or cannibalise your direct customers. Buyers choose on coverage, quality and availability — so you reach people who’d never have found you, without giving anything away to the ones you already have.

🔁 Reach them once, keep them coming back

The first sale is the introduction; the top-up is the relationship. Every renewal, upgrade and second trip runs back through your offer at your price — no reacquisition spend, no intermediary re-pitching your customer to someone else.

⚡ Listed in minutes. Bought in seconds.

No contract cycle, no negotiation, no integration committee. Technical compliance is the only gate, and the full path from posted offer to working eSIM is proven end to end.

🔄 Sell voice, data or text — separately or together

Each modality is independently priceable and purchasable. Reprice, add coverage or withdraw anytime. Your own catalogue is never ranked as competing with itself.

📍 Direct to the device, wherever your coverage reaches

The buyer downloads the profile from your SM-DP+ and takes radio service from you. blocfone is never in your data path.

✓ Delivery verified, not assumed

Every order is watched to completion and attested on-chain. Non-delivery refunds automatically — no dispute, no chargeback, no collections, no reconciliation cycle.

💵 You keep 85%, and you know exactly what was sold

The platform rate is stamped into the order at purchase and emitted at settlement. Against wholesale chains that take 40–70% and never tell you what retail price your service finally reached, you see every sale, every price, every time.

Coming next

💰 Settlement straight to your wallet

The split is already computed and stamped on every order, and the payout destination is a parameter waiting on an address. Give us a wallet and USDC lands with you the moment delivery is confirmed — no invoicing, no month-end, no receivables.

📜 A permanent record of every sale

Orders will persist on-chain after settlement — a durable, independently checkable record of what you sold, what was delivered and what you were paid. Yours to audit without asking us for a report, and the point at which platform neutrality becomes something anyone can verify for themselves.

🪪 Identity without the paperwork

Identity and payment already run as separate wallets: the wallet that proves who someone is never has to be the one that pays. As government and bank ID wallets arrive, that separation lets you sell permanent, portable numbers with regulator-grade assurance, without ever holding a buyer’s documents. The number classes are already modelled and enforced.
