Payments — AETHER

Atomic, end to end

Every payment is one transaction. Identity verification, sanctions screening, FX quoting, multi-leg routing and final settlement happen inside a single atomic operation. If any step fails, nothing moves and nothing is owed.

The rail uses a synchronized PvP/DvP construction over tokenized cash, native CBDCs and regulated stablecoins as the underlying value.

Coverage

Fiat currencies: 47 currencies routable end-to-end through partner liquidity providers. Including all G10 plus major EM corridors.
CBDCs: 9 central bank digital currencies live; 4 additional integrations in pilot. Direct wholesale and tiered retail access where regulators permit.
Stablecoins: Regulated cash-backed stablecoins from licensed issuers (USDC, EURC, XSGD, BRL1, MXNB, and others).
Formats: ISO 20022 native messaging. Adapters for SWIFT MX/MT, SEPA INST, FedNow, RTP, FPS, PIX. Drop-in for existing payment ops.

Inside a payment

PHASE 01

Verify

The rail verifies sender and beneficiary DIDs. Sanctions, PEP and travel-rule screening run in parallel against current lists.

PHASE 02

Quote & route

AETHER quotes FX against committed liquidity, picks a path across the network and locks it for the settlement window.

PHASE 03

Settle

All legs commit atomically. Counterparties receive ISO 20022 confirmations and an attestation hash for audit.

Operational fit

Drop-in next to existing rails. Run AETHER alongside SWIFT or domestic ACH. No big-bang migration required.
No nostro pre-funding. AETHER sources and posts liquidity just in time against the committed quote.
Reconciliation by construction. Settlement and confirmation are the same event, so there is no DvP gap to reconcile.
Reversals where they make sense. Disputed retail payments use a signed reversal flow; wholesale payments are final by default.
