Finteum joined the Ecosystem TestNet - built in partnership with Adhara - and completed testing of the interoperability of the two systems (Finteum’s platform and both FnPS), successfully demonstrating interoperability and the ability to settle intraday FX swaps in a matter of seconds.

The transactions were triggered by the Finteum’s Platform, which is built on R3’s Corda Protocol, and settled on a PvP basis through two FnPSs, each representing the 2 different currencies (GBP and USD). Settlement status information then was communicated back to the Finteum’s Platform dashboard, proving that interoperability can be achieved in both directions between Corda and Enterprise Ethereum.

Connecting to the Ecosystem TestNet, Finteum was able to prove that when two large banks agree to execute an T+0 intraday FX swap with each other, an instruction can be communicated successfully to the FnPS, and both the near and far leg of the transaction can be settled quickly. Based on Finteum’s testing, the average time for 4 test transactions executed in quick succession was under 10 seconds.

Finteum and Fnality previously conducted the first successful interoperability test in 2019. However, this latest test conducted through the Ecosystem TestNet was designed to simulate conditions that reflect the desired end state in a live environment. Given these promising results, the Fnality and Finteum teams are now confident that the two systems will also be interoperable once they go into production. Once live, Banks will be able to agree and execute a trade in the Finteum Platform and settle it PvP via the FnPS in seconds, even when there is heavy traffic on both systems and the underlying RTGSs are closed (for example, during the night).

Three large banks have committed to go live with the Finteum Platform for intraday FX swaps in USD, GBP and USD in Q2-Q3 2023. Depending on the speed of currencies going live in FnPS following regulatory reviews, these transactions may need to initially settle outside of FnPS. In the event that the transactions will initially settle outside of FnPS, migrating the transactions to PvP settlement in FnPS will reduce settlement risk for the financial system.

Brian Nolan, Co-founder of Finteum, said: "The Finteum client banks’ first preference is to settle these transactions on a PvP basis in FnPS, which aligns with the goal of the CPMI to increase PvP usage. The Finteum team hopes that central banks and regulators will be able to find time to prioritise the review of FnPS, so that systemic risk can be minimised."

Rhomaios Ram, CEO at Fnality International, said: “This PvP PoC is a significant step for Fnality as it proves that once the Fnality Payment System is live in a second jurisdiction, participants will be able to swap and atomically settle funds from their home currency to another currency and vice versa in a matter of seconds.”

Peter Left, Head of Prudential Liquidity Management at Lloyds Bank, said: “Cross-chain payment versus payment FX dramatically reduces settlement and credit risks. Having trades agreed on an intraday trading platform and be indivisibly settled in near real-time across two Fnality Payment Systems will help significantly reduce liquidity costs across the industry.”

Julio Faura, CEO at Adhara said: “It continues to show how valuable a collaborative wholesale TestNet can be and has proven once again the seamless value Adhara’s Digital Cash (DC) Commander can add to Bank Treasuries; helping them easily engage, control and ultimately increase their understanding of how this future model for finance comes together for them.”
