Saleem | Stablecoin Payment Infrastructure for the Unbanked

The Problem

1.4 billion people have a phone.
Not a smartphone. Not a bank account. A phone.

No Smartphone

82M Pakistanis. 18M+ Syrians. 100M+ Bangladeshis offline. Feature phones running RTOS. No app stores, no data plans, no fintech.

No Bank Account

65% of Pakistani adults unbanked. Syria's formal banking sector non-functional for most citizens.

Extortionate Fees

Western Union, OMT and similar services can reach 7 to 12% all-in on these corridors once fees and FX are counted. Hawala rates hit 5 to 35%. Billions flow through informal corridors.

Hawala Dependency

Syria's real payment system is the sarraf network: 5,000 to 10,000 agents, informal, unregulated, no digital infrastructure.

5 to 35% Informal Hawala Networks

The Solution

One wallet. Every device. One stablecoin rail.

Stablecoins without smartphones. Inclusion without internet.

Saleem Android / iOS wallet home screen — Android / iOS

Saleem Merchant POS: any phone becomes a terminal — Merchant POS · on any phone

And the merchant is just another phone.

The same wallet runs as a front-of-house POS: any KaiOS or Android phone becomes a terminal, no dedicated hardware. The optional Ingenico AXIUM D8 is for high-volume merchants only.

On KaiOS, one device runs both the wallet and the merchant POS, so value can be sent, received, and spent at a local shop without ever leaving KaiOS, with the merchant accepting it on another KaiOS phone.

Revenue Model

Five diversified streams · recurring, scaling, compounding.

SaaS-led revenue across five streams, none dominant. Strong Year-5 trajectory with compounding ARPU.

SaaS & API licensing
FX spread
Bank revenue share
Sarraf share
Telco USSD share

Schematic: five streams, none dominant. Per-stream economics in the white paper.

Five revenue streams. SaaS and API licensing · FX spread · bank revenue share · sarraf share · telco USSD revenue share. Saleem takes no yield on customer balances. Any incidental yield is ring-fenced for the Humanitarian SIM Allocation Fund. Riba-avoidance by design.

Per-stream economics, per-year projections, per-market sensitivity and per-partner unit economics in the white paper.

For Telcos

You already own the SIM. Now own the stablecoin wallet that runs on it.

Telcos already hold the customer relationship banks can't reach. Saleem turns the SIM into a financial product: new ARPU, no app-store dependency.

Receiver-side telco

Be the bank the country forgot.

Where banking is broken or absent for the bottom 60%, the MNO is the institution that still works. Saleem turns every SIM into a wallet that receives remittances, holds value, and cashes out at the corner agent, with no smartphone, bank account, or internet. Become the financial layer the underserved have never had.

Sender-side telco

Own the remittance flow below the apps you already have.

Your customers send billions home through Western Union, OMT, and smartphone-only fintechs, none of which are yours. Saleem powers a remittance layer beneath your existing apps, capturing the diaspora flow on the SIM the customer already trusts. The stickiest, highest-margin product in mobile, handed to the carrier.

Two ways to live in your subscriber's pocket

If you already have a payment app

Reach 100% of your subscribers.

Your app serves the top 30 to 40% with smartphones and data. Saleem layers the same wallet onto USSD and SIM Toolkit, reaching every subscriber on every device, including the feature phones your app can't touch. Your app stays front of house; Saleem closes the gap to 100%.

If you don't have a payment app yet

White-label Saleem as your own.

Launch a branded wallet under your name without building one. Saleem provides the stablecoin rail, compliance, custody, and operator console; you provide the brand, distribution, and customer relationship. Live in months, not years, with compliance and custody handled for you.

Why MNOs sign: new ARPU on top of voice and data · SIM-anchored, so near-zero churn · no app-store gating · MNO retains the customer relationship and the larger share of every flow.

Remittance Captivity Flywheel

Remittance → Bills → Interchange → Micro-Credit → 3 to 5x Lower Churn

The bank keeps its customer relationship.

Eight markets · 500M+ addressable SIMs

Syria · Lebanon · Pakistan · Bangladesh · Egypt · Ethiopia · Kenya · Somalia. ~438M adults · ~277M unbanked · 500M+ addressable SIMs. Per-market adults, unbanked %, no-smartphone % and corridor-by-corridor economics in the white paper.

For Blockchain & Stablecoin Issuers

For NGOs & Humanitarian

Every dollar, from donor treasury to beneficiary mobile, visible and auditable.

The hard part of humanitarian disbursement isn't moving money, it's proving where it landed. Saleem is designed to replace opaque cash-and-hawala chains with a stablecoin rail that leaves a tamper-proof on-chain record from donor to recipient.

Pay staff and aid recipients without cash leakage, opaque routing, or middleman skim.

Why NGOs choose Saleem

No Saleem fee

No Saleem fee on disbursed value.

No hawala cut, no correspondent fees. FX conversion applies where currencies convert, with details shared post-NDA. Designed to deliver value to the recipient's SIM on any phone.

Cryptographic proof of delivery

Donor-to-recipient visibility.

Every disbursement is on-chain from donor authorisation to recipient wallet. Programme teams get a live, queryable record and donors see exactly where the money went. No six-month reconciliation cycles.

Tamper-proof audit trail

Reach the unreachable, prove it later.

Reach beneficiaries in conflict-affected, banking-broken environments at the audit standard of a regulated bank transfer. Every record exportable, every flow defensible to your auditors and board.

Live in the Operator Console

Saleem desktop operator console: humanitarian bulk disbursement module — Humanitarian bulk-disbursement module: built into the operator console alongside compliance, treasury, and travel-rule surfaces. Reference programmes, pricing, API documentation and integration timelines available post-NDA.

For Corporates

Pay staff and suppliers across borders. Without bank wires.

Diaspora employers, BPOs, NGO field offices, and regional supplier networks pay people in countries where banking is broken or expensive. Saleem provides the corporate operator console, stablecoin payroll rails, and recurring payee management.

Stablecoin Payroll

USDT or USDC settlement. Recipients claim in local currency at the nearest sarraf, agent, or bank mobile-money on-ramp.

Cross-Border Invoicing

Replace SWIFT wires with on-chain settlement. Suppliers in Syria and Pakistan paid in hours, not days.

Recurring Payees

Persistent payee management for monthly payroll batches and contractor disbursements.

Saleem Corporate Operator console: dashboard — The Corporate Operator console: treasury, invoices, payees, commissions in one place.

For Sarrafs

Formalise the corridor. Earn from every flow.

Syria's informal hawala network is the country's real payment infrastructure: 5,000 to 10,000 sarrafs moving $1 to 2B annually. Saleem keeps the agent at the centre of the relationship while giving them tooling, commission tracking, and a settlement rail their incumbents cannot match.

Cash-in / Cash-out Agent

Become an onboarded Saleem agent. Convert cash to USDT for senders, USDT to cash for receivers. Earn commission on both legs.

Real-time Commissions

See every earned commission as it settles on-chain. No end-of-week reconciliation, no opaque skim.

Compliance Without Friction

TRM + Chainalysis screening is built into the rail the sarraf operates on.
