The ISO 20022 Gateway
for Solana Stablecoins

Open-source infrastructure that bridges Solana stablecoin transactions to ISO 20022 — the universal financial messaging standard. Generate bank statements, custody reports, and payment orders. 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. Not limited to payments or to any specific geography.

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.

Demo video — recording in progress

Will be embedded here before the March 22 deadline.

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.

Beyond Payments

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