Post-Quantum Secure
Financial Operating System
Built For You

Ready-To-Deploy sovereign digital infrastructure for finance, from money transaction settlement rails and asset tokenization to digital identity management and publicly-verifiable certification, Shamwari equips governments, financial institutions, private enterprises and governments across Africa and wide emerging market economies with an integrated platform to transact, issue, and scale financial services under PQC security.

THE PROBLEM

Central banks, commercial banks, governments and financial service providers across emerging market economies are up against the same three problems: significant populations structurally locked out of formal finance, legacy transaction rails that were never built for both regulatory-compliant digital money or digital-first finance and a quantum threat most institutions haven't started planning for but is on the horizon. Shamwari closes all three through architectural design.

FINANCIAL EXCLUSION
1.7B
Unbanked Adults Globally
  • Sub-Saharan Africa: 57% financial exclusion rate
  • LATAM & Caribbean: 46% fintech growth gap
  • ASEAN: 44% annual expansion potential
  • $48B extracted annually from remittance corridors
  • Existing rails require a bank account to reach a bank account
LEGACY INFRASTRUCTURE
15–20%
Bank OpEx On Inefficient Core Legacy Systems
  • Core banking platforms are designed for yesterday's transaction-processing and siloed ledgering, not real-time 24/7 local and cross-border settlements
  • Compliance, KYC, and tax collection applied through fragmented processes with high-overhead cost
  • Correspondent banking rails plagued by T+2 to T+7 settlement delays and expensive 8–13% cross-border fees
  • Opaque transaction tracking requiring costly manual reconciliation and interbank clearing houses
  • Security built on increasingly vulnerable, legacy RSA/ECDSA encryption facing harvest-now-decrypt-later quantum risks
QUANTUM THREAT
2030
NIST Migration Deadline
  • ECDSA/RSA chains and banking systems are currently exposed to "harvest now, decrypt later" attacks that could be happening today.
  • Historical transaction data on today's public blockchains is at risk of retroactive exposure as quantum-computing develops.
  • Popular existing blockchains have not started migration to PQC security while most have no concrete roadmaps at all.
  • Google warns that powerful quantum computers could break most standard encryption systems as early as 2029.
  • Migration from existing cryptographic algorithms to PQC will pose risks from implementation immaturity to slow adoption and performance limitations.

SHAMWARI AS A SOLUTION

Shamwari is positioning as a next-generation, post-quantum resilient blockchain platform designed to serve as a sovereign, multi-chain financial operating system engineered to meet the infrastructure and regulatory demands of today's digital financial economy; particularly across Africa and further, the MENA, regions. As a platform, Shamwari provides a future-proof foundation for secure banking, local and cross-border payments and transactions processing as digital asset and identity management systems built on PQC security.

WHERE EXISTING SYSTEMS FAIL
1
Identity data management systems and infrastructure is not shareable, interoperable or adaptable.
Banks require government-issued ID and a fixed address. Approximately 1.1 billion people globally have no legal identity documents. and without identitification, owning a bank account is difficult if not impossible. Without a bank account, people therefore have no access to savings, credit or safe and formal remittance channels. Each institution/organization currently has to process and collect PII data independently which is costly and tedious for consumers.
2
~12% Charge Fees On Remittances
For context, Sub-Saharan Africa is the world's most expensive remittance corridor where billions in fees annually are charged on the people who can least afford them, significantly impacting their livelihoods before the money ever reaches their families. This pushes people to informal and risky alternatives that fuel informal economies and lead to money theft and loss.
3
Non-existent Credit Systems
MFIs rely on informal credit assessment and high operational costs. No publicly-verifiable or accessible credit records are available and therefore no informed or flexible underwriting or collateral mechanisms are put in place. Without a bank account, informal lenders take advantage and charge 40% - 200% APR.
4
Smart-contract chains don't solve it
Generic blockchains bring gas fees, wallet complexity, and compliance that lives in application code and not proper enforceable regulation. DeFi apps cannot be a substitute for regulated financial infrastructure, especially not for people earning a few dollars a day working in informal, cash-paying jobs.
HOW SHAMWARI RESPONDS
BARRIER 1: ARCHITECTURE
TWO-TIER DESIGN
Shamwari's architecture is built on a dual-chain design that separates a primary settlement layer from jurisdiction-specific child-chains. This allows the provision of embedded core financial services, multi-jurisdictional compliance and single-account access to the system while maintaining low-cost interoperability across supported markets.
BARRIER 2: IDENTITY DATA
On-chain Encrypted and Typed Identity Data
All Shamwari accounts depend are based on permission and owner type assignments built around the demands of regulators on institutions that provide financial services, with KYC data encrypted on-chain using post-quantum cryptography. Regulator-issued digital certificates can replace or compliment paper-based KYC, enabling instant account opening, verification and registration from any internet-enabled device, without requiring a branch visit, manual paperwork submissions and processing costs.
BARRIER 3: MONEY TRANSFERS & REMITTANCES
CROSS-CHAIN TRANSACTION SETTLEMENTS
Shamwari settles both local and cross-border transfers and payments directly between accounts and jurisdiction chains without any extra charge, confirmation or settlement steps. A built-in FX exchange also offers seamless conversions between currencies for cross-border transactions, ensuring money or a payment is received in under a minute, in legal tender without the need for a correspondent bank or a SWIFT round-trip.
BARRIER 4: CREDIT HISTORY
On-chain credit history and P2P lending
Shamwari records every, transaction from payments, repayments, default and collateral on an immutable on-chain record, enabling verifiable credit and financial histories availability to people outside the banking system. Credit scoring by MFIs and FSPs becomes easier and justifiable while also providing full loan lifecycle data, and collateral submissible on the platform as tokenized digital assets.
WITHOUT SHAMWARI
Branch visit required. Average 9.4km to nearest bank branch in rural Sub-Saharan Africa.
Remittance fees of 8 - 12%. $200 sent home costs $16 - $24 in fees.
No credit history means no loan access. Informal lenders charge 40 - 200% APR with no borrower protection.
VS
WITH SHAMWARI
Account creation and management from any internet-enabled device. PQC keypair generated locally. Digital certificates replace document KYC.
Cross-border settlement in under a minute. Built-in DEX with tax withheld at execution. Zero corridor fee.
Every transaction builds an immutable credit record. MFI lenders access full on-chain loan lifecycle with collateral enforcement.

CRYPTOGRAPHIC FOUNDATION

Quantum-resistant by
design.

Two NIST-standardised post-quantum algorithms secure every account, transaction, block and all data eliminating migration risks, costs and service disruptions.

ML-DSA: Dilithium
NIST FIPS 204
Each Shamwari transaction, block and certificate is signed with lattice-based cryptography that stays secure even against future quantum computers that can attack and break classic ECDSA and RSA algorithms.
ML-KEM: Kyber
NIST FIPS 203
Encrypts account identity, KYC records, messages and payment payloads using hybrid key encapsulation plus AES-256-GCM before submission to the blockchain, so sensitive data stays secure even from an attacker recording today's traffic to decrypt once quantum computers arrive (Harvest Now, Decrypt Later).
BIP39 PQ Adaptation
WALLET RECOVERY
Deterministic account generation, security and recovery from one 12/15/18/21/24 word backup passphrase for both single passphrase accounts and seed-based accounts. The backup phrase recovers both your signing and encryption keys, with a familiar self-custody recovery experience already implemented existing crypto wallets, with the NIST-standard security running beneath it.
JVM-Native PKI
CERTIFICATES
Shamwari certificates plug into standard Java enterprise infrastructure with no custom integration layer. If your systems already accept digital certificates, they can accept Shamwari's post-quantum based certificates with minimal systems redevelopment.
