MONEY MOVEMENT INFRASTRUCTURE FOR AFRICA
One integration.
Every rail.
Collect and pay out across every rail through one platform. Build on the API, or launch on the whitelabel merchant solution — authenticate once and reach Ledger, Bankrail Gateway, and every product you enable.
TWO WAYS TO BUILD
Integrate the rails, or launch on them.
FOR DEVELOPERS
Build on the API
One signed integration to reach every product. Byte-faithful passthrough, exact-string money, and each product in its own native vocabulary — you compose the product you want.
- — HMAC or JWT auth, one identity
- — Self-serve sandbox in minutes
- — Ledger, Bankrail, and more
FOR BUSINESSES
Launch on the platform
A whitelabel merchant solution over the same rails. Collect into virtual accounts, settle to sub-accounts, and pay out — with the books kept accounting-grade underneath, no engineering team required.
- — Collections and payouts, one dashboard
- — Multi-tenant, whitelabel-ready
- — Reconciliation built in
PRODUCTS
Two products, one front door.
Ledger and Bankrail Gateway each stand alone and speak their own native vocabulary. The One API is the single, entitled access layer that reaches both — you never integrate a product directly.
POSITIONS ENGINE
Ledger
A double-entry, accounting-grade positions engine. Provable balances, enforced idempotency, and an audit-grade export that reconstructs state exactly.
Documentation →COLLECTIONS & PAYOUTS
Bankrail Gateway
The bank rail for moving money in and out. Virtual accounts, checkout intents, outbound transfers, and signed, idempotent callbacks.
Documentation →WHY POSTEERING
Infrastructure that keeps the discipline.
Orchestration, never absorption
The platform holds no balance, no position, and no money of its own. It routes, entitles, and correlates — you keep ownership of your product and your domain.
Byte-faithful passthrough
Every call reaches a product in its own native vocabulary and returns the product's own response unchanged — exact status codes, exact error classes, no reshaping.
Money is never parsed
Amounts move as exact strings and may exceed 2^53 without losing precision. The gateway forwards the bytes as sent — accounting-grade from edge to edge.
One identity, fail-closed
Authenticate once; entitlement is enforced before any product is contacted. A call to a product you are not entitled to is denied at the gateway, every time.
GET STARTED
One integration. Every product.
Onboard through the One API and reach every product you enable from a single signed surface. Self-serve products provision instantly; you authenticate once and go.
