Circle-8 Ledger Ltd — B2B Payment Infrastructure

Trade payments that never come back to haunt you.

Leja is multi-rail payment orchestration for regulated cross-border trade — ISO 20022 messaging, tranche-based settlement and blockchain settlement, built into the payment itself. So when the bank calls, the answer already exists.

ENTRY 01 The Problem

The payment that comes back to haunt you

A legitimate cross-border trade payment goes out. The business moves on. Months later, a bank or a regulator asks the sender to explain that transaction — and if a clean answer doesn't exist, the money doesn't come back.

It happens at every scale — from first-time exporters to the largest corporates.

ENTRY 02 Why This Happens — Part 1

Rails, explained

A cross-border payment travels through a chain of correspondent banks to get from your bank to the recipient's. Each hop is built to move an amount, reliably, from one account to another.

Correspondent BankHop 1

Correspondent BankHop 2

Recipient's BankDestination

Each hop moves money. None carry the reason why. The rails move value — they don't move meaning.

ENTRY 02.2 Why This Happens — Part 2

ISO 20022, explained

ISO 20022 is the industry's emerging global standard for payment messaging. Instead of a bare amount and reference, it carries structured, richer data with the payment itself. The fix already exists at the standards level — the gap is who's actually building on it for corridors like these.

ENTRY 03 How Leja Works

Trust, built into the payment itself

Three mechanisms work together so every transaction is self-documenting by design — not reconstructed after the fact.

Mechanism 01 · Core

Tranches

Trade payments don't have to be a single leap of faith. Documentary collection structures release funds in stages, tied to verified trade documents.

D/P — Documents Against Payment: the buyer must pay before receiving shipping documents.

D/A — Documents Against Acceptance: the buyer commits to a future payment date to receive documents.
Mechanism 02 · Settlement

Blockchain settlement

One tool in the stack — not the headline. Stellar-based settlement gives Leja two practical things, kept deliberately simple.

Speed — funds move across borders in minutes, not days.

Immutability — nothing can be quietly edited or deleted.
Mechanism 03 · Messaging

ISO 20022, native

Every transaction is recorded with structured, standards-based data from the moment it's created — not bolted on for compliance later.

Built in — purpose codes, invoice references and verified counterparty data travel with the payment, automatically.
ENTRY 04 The Payoff

Before Leja / After Leja

Same SME. Same transaction. A different ending.

Compliance call — no warning Proof already attached
Scrambling for proof Answered in minutes
Penalty deducted No penalty
ENTRY 05 Where We Start

Built for global trade

Leja's architecture isn't specific to any one trade lane — it's built for global trade. The active go-live focus is Africa-to-Africa corridors, settled via Yellow Card's Convert Fiat Currency rail, with more currency pairs added as each is live-verified. The original India-origination corridors are built, working and available — held for when that origination pipeline reopens.

LIVE FOCUS

South Africa – Malawi
LIVE FOCUS
NGN → KES
Nigeria – Kenya

INR → NGN

The destination is global. Africa-to-Africa is where the model is live today — not the ceiling.
