SBI Holdings and Doppler Finance have rolled out a new XRP-based payment architecture designed to speed up settlements for local banks. The system, announced July 15, uses XRP tunnels to improve transaction finality while staying within Japanese regulatory guidelines.
What the architecture does
The collaboration focuses on building XRP-powered corridors that let banks settle payments more efficiently. Doppler Finance, a fintech firm specializing in blockchain-based payment rails, worked with SBI to ensure the architecture meets Japan's standards for transaction finality. That means once a payment is confirmed on the XRP Ledger, it's considered final under local rules — a key requirement for banks that need certainty before releasing funds.
Japanese banks have been exploring faster cross-border and domestic settlement options, but regulatory clarity has been a hurdle. By embedding XRP tunnels directly into the payment flow, SBI and Doppler aim to give banks a compliant way to cut settlement times from days to seconds. The architecture doesn't require banks to hold XRP; it uses the token as a bridge asset, converting fiat to XRP and back within the same transaction.
Regulatory alignment
The system was built to comply with Japan's Payment Services Act and guidelines from the Financial Services Agency. Doppler Finance said the architecture secures transaction finality by leveraging the XRP Ledger's consensus mechanism, which the company says has been vetted by Japanese regulators. SBI, which has a long history of working with Ripple, the company behind XRP, is handling the integration with local financial institutions.
The companies didn't name specific banks that have signed on or provide a timeline for when the tunnels will go live. SBI and Doppler said they're in talks with multiple institutions, but no contracts have been announced. For now, the architecture is available for testing, and the firms expect to share more details in the coming months.
