What Is A2P SMS and Why Does It Create DeFi Yield?

Every time you verify your identity — logging into Google, confirming a payment, resetting a password — a message travels from an application server to your phone number. That message costs money. Someone bills for it, someone pays for it, and somewhere in the chain there is a receivable.

SukukFi Phase 3a finances part of that chain. The ultimate obligors are Google, Meta, TikTok, Twilio, and similar hyperscaler platforms. The structure is Murabaha — a fixed-markup prepayment — and the yield comes from real traffic settlement, not from protocol tokens.

What A2P SMS is

A2P stands for Application-to-Person. Unlike P2P SMS (one person texting another), A2P is software sending messages to humans at scale: two-factor authentication codes, order notifications, appointment reminders, marketing campaigns. Google alone sends hundreds of millions of OTP messages per day globally.

A2P traffic is commercially distinct from regular messaging. Mobile network operators (MNOs) charge premium rates for A2P traffic because it is higher-value, higher-volume, and analytically distinct from peer messages. But collecting that revenue is complicated.

The SMS firewall model

An MNO — say, Ncell in Nepal — might receive inbound A2P traffic from dozens of different aggregators, all routing OTP messages from platforms like Google, Meta, and TikTok to Ncell subscribers. Without control over that traffic, the MNO cannot enforce its rates, detect fraud, or collect consistently from every aggregator.

SMS firewalls solve this. A firewall operator negotiates an exclusive agreement with the MNO: all inbound A2P traffic is routed through the firewall, which classifies messages, enforces licensed routes, filters spam, and provides analytics for accurate billing. The firewall operator becomes the single point of contact for A2P settlement on that network.

In exchange for this exclusivity, the firewall operator typically prepays the MNO for capacity — guaranteeing a minimum revenue commitment upfront, then recouping it through aggregator billing as traffic flows through.

This is where SukukFi enters.

Hayo Telecom and the prepayment gap

Hayo Telecom is a US-based global telecom service provider deploying SMS firewalls on MNOs in emerging markets. Hayo has negotiated exclusive A2P gateway agreements with MNOs including Ncell (Nepal), Smart Axiata (Cambodia), and Zamani (sub-Saharan Africa). Under these agreements, Hayo commits to prepay the MNO for 12 months of A2P capacity.

The problem is float. Hayo needs to pay the MNO upfront but collects from its customers — Google, Meta, TikTok, Twilio, Sinch, Bird — on 30-to-45 day terms after traffic has settled. The gap between the prepayment obligation and the collection timeline requires working capital.

SukukFi Phase 3a fills that gap. LP stablecoins fund the prepayment to the MNO. As Hayo's customers pay invoices, the vault is repaid with a fixed markup on the deployed capital.

The economics

For the Ncell deal in Nepal:

• Prepayment: $7.5m to Ncell for 12 months of exclusive A2P capacity
• Monthly invoices from Hayo's customers: $1m
• Monthly vault repayment: $750k
• Fixed markup over the cycle: $1.5m total
• Gross yield: 20% APY on the $7.5m deployed
• Net to LPs: ~16% APY after SukukFi's 20% performance fee on profit

The markup is fixed and agreed before deployment — this is Murabaha, not profit-sharing. SukukFi effectively buys the right to Hayo's receivables at a disclosed markup and sells that right to LPs through the vault.

Hayo's customers include some of the largest companies in the world. Google, Meta, and TikTok generate billions in revenue. Their 30–45 day payment terms are operationally standard, not a sign of credit stress. The risk is not whether these companies will pay — it is whether Hayo collects consistently and routes payment through to the vault IBAN managed by Fuze Finance.

Why the ultimate obligors matter

Most receivables financing focuses on the immediate counterparty — in this case, Hayo. But what makes Phase 3a structurally distinct is who is at the end of the payment chain.

The invoices Hayo issues are for A2P traffic sent by hyperscaler platforms. Those platforms pay because their product — the ability to send OTPs to users globally — depends on Hayo's network access. If Hayo's Ncell agreement lapses, Google cannot reach Nepalese subscribers. These are not discretionary payments.

Each Hayo customer receives an assignment-of-receivable notice under English law directing invoice payments to a Fuze Finance IBAN controlled by SukukFi. Legal enforcement sits at the top of the chain, not just at the Hayo level.

What changes with Phase 3a

Phase 1 finances voice traffic — minutes delivered by a telecom intermediary to a national MNO. The underlying asset is a completed call.

Phase 3a finances infrastructure deployment — an exclusive gateway agreement secured by prepayment. The underlying asset is 12 months of network access rights. The return is a fixed markup on that prepayment, not a per-minute spread.

This is Murabaha rather than Mudarabah: SukukFi buys access to the receivable at a disclosed markup agreed before the transaction, then sells it to LPs at that same markup. There is no variable profit share based on traffic volume — the markup is fixed from day one.

The gross yield (20%) is comparable to Phase 1's 21% gross. Net to LPs is ~16% after the performance fee, versus 16.8% for Phase 1. The lockup is longer and the prepayment structure carries more operational complexity. LPs who deposit into Phase 3a vaults are funding real infrastructure, collecting from real hyperscaler platforms, and waiting for real invoice cycles to settle.

That is what A2P SMS yield looks like when it reaches DeFi.
