The ISO 20022 Gateway
for Solana Stablecoins

Open-source infrastructure that turns Solana into a Global RTGS — real-time gross settlement at ~$0.001 per message, zero bank permission required. Generate bank statements, custody reports, and payment orders in ISO 20022 XML. Import into any ERP or accounting system.

01 — The Missing Piece

ISO 20022 integration is a precondition for institutional stablecoin adoption

Stablecoins are fast and cheap. But companies can't adopt them until their ERP, accounting, and treasury systems can understand stablecoin transactions. That requires ISO 20022 — and until now, no open bridge existed.

📊

ERP systems don't speak blockchain

SAP, Oracle, Bexio, Abacus — they all import ISO 20022 XML. Solana transactions are invisible to these systems without a translation layer.

🔒

No open standard exists

Ripple claims ISO 20022 alignment but provides no public documentation, tooling, or message generation. It's a black box. Solana had nothing — until now.

🧩

No reference reconciliation

Business payments rely on structured references (QR references, SCOR) for automatic matching. Blockchain memos carry no standard format for this.

🏦

TradFi → DeFi transition blocked

Without ISO 20022 compatibility, companies face a binary choice: bank rails or crypto rails. The gateway makes them composable.

Why this matters for Solana ISO 20022 support is often cited by Ripple/XRP advocates as a key differentiator. Now Solana has an open-source, source-available implementation — not limited to payments, not limited to one geography, and with full documentation. This is general infrastructure that any Solana stablecoin project can build on.
02 — What We Built

Two products. One payment round-trip.

A message gateway (our hackathon submission) and a payment app that together close the loop from invoice to on-chain settlement to accounting import.

Solana ISO 20022 Gateway

iso.gbits.io · github.com/gbits-io/isofix

Bidirectional message gateway. Reads Solana stablecoin transactions, generates compliant ISO 20022 XML — bank statements, payment notifications, securities custody reports. Or takes an ISO 20022 payment order and executes it as a Solana SPL transfer.

UI mode: Upload pain.001 in browser, sign with Phantom / Solflare. REST mode: ERP POSTs pain.001, gateway executes and returns pacs.002 status.

Gbits Pay

app.gbits.io

Scan or upload a Swiss QR invoice and pay it with stablecoins on Solana. The QR reference is embedded as an SPL Memo for downstream reconciliation by the gateway. A showcase of what becomes possible when stablecoins speak ISO 20022.

03 — Technical Deep Dives

See exactly how it works

Interactive flow diagrams and field-level mapping documentation. Early visitors have told us these pages were the most compelling part of the project.

04 — Demo

See it in action

Live apps running on Solana mainnet and devnet.

05 — Architecture

Single HTML file. Zero dependencies. Fully auditable.

No React, no Node.js, no build tools. Open the file in a browser and it works.

QR Reference Reconciliation

QRR: prefix in SPL Memo maps to <CdtrRefInf> in camt.053/054. Auto-match in accounting software.

IBAN → Solana via SNS

verified-iban.sol Bonfida subdomains resolve bank IBANs to Solana wallet addresses. DNS-style attributes on each record can specify token preference (USDC, EURC), legal entity name, and more.

Beyond Payments

semt.002 generates securities custody reports for SPL token holdings. The gateway is not payment-only infrastructure.
