One API for every layer of a stablecoin payment.
Causeway is an API platform for stablecoin payment operations (quotes, wallets, ledger, on/off-ramp, custody, and compliance) with the regulated pieces plugging in at defined adapter boundaries. Built for fintechs, PSPs, and businesses moving value through African money corridors.
Moving stablecoin value across African corridors means being four companies at once.
A chain integrator, a wallet custodian, a compliance operator, and a reconciliation shop. Each layer is licence-heavy and slow to build, and most of it has nothing to do with the product you want to ship.
Causeway offers every technical layer as one interface, leaving only the genuinely regulated pieces (real custody and licensed cash movement) to attach at a defined adapter boundary where a licensed partner plugs in.
You can build and run the wallet, payments, and compliance yourself, and add licensed custody later.
Custody attaches as a deliberate later step behind a defined adapter boundary, so the licensing question never blocks integration. You build and test the whole flow first (wallet, payments, compliance, and ledger, through the Causeway API), then plug the regulated piece in.
A supplier payout has been submitted through your Ghana corridor, larger than usual. Before it settles, Causeway holds it for a person to review. You open the Management Portal to clear it.
- 01 · Dashboard
You see the hold on the Dashboard
The day's activity is normal except for one payout on hold, waiting on a decision. You click through to it.
- 02 · Queue
The queue shows why it stopped
The payout tripped your risk policy by crossing your review threshold for this corridor. Nothing settles until someone with authority signs off.
- 03 · Customer
You check the customer behind it
One click opens the customer's record: KYC status, latest screening result, and the payouts they've sent before. This one fits their pattern, and the counterparty is clean.
- 04 · Release
You release it
You approve the payout from the queue. It leaves the hold, settles through the corridor, and the decision is recorded under your name.
- 05 · Ledger
A week later, you can account for it
An auditor asks about that payout. You pull the same record: who reviewed it, when, and on what basis: straight from the log.
No payout settles without clearing this gate, and every hold, release, and rejection is recorded. Today Causeway proves every step without moving real money; the leg that moves funds switches on once a licensed cash-movement partner is in place.
Every payout waits for a person to approve it, and the decision is on the record.
Every hold and release lands in one log with a name and a reason, so when the auditor asks, the answer is already there.
Build the whole flow on the testnet today.
Everything demonstrable today runs on testnet or in intent-only mode, where Causeway records the evidence and emits a webhook but moves no funds. There is no production deployment or licence yet; each is a gated milestone. The first corridor is Ghana GHS to USDC.
