Alipay+ users globally, every one of them now able to pay at a GrabPay merchant in Singapore using their home wallet, in their home currency.
How StraitsX made cross-border digital wallet payments feel as seamless as local ones.
Singapore's MAS-licensed Major Payment Institution turned the XSGD stablecoin into a settlement rail connecting Alipay+ travellers with the entire GrabPay merchant network, instant FX, 24/7 settlement, no merchant onboarding required.

The Friction
Tourists arrived ready to pay. Local checkouts wouldn't accept them.
Alipay+ users could only transact at merchants explicitly onboarded to the Alipay+ network. GrabPay, Singapore's most widely accepted payment method, sat outside that loop. The result was a fragmented QR ecosystem and missed transactions on both sides.
100,000+
Singapore merchants in the GrabPay network reachable through a single integration, cafes, convenience stores, boutiques, hawker stalls, all enabled with no new hardware or onboarding.

International payment apps across 14 countries now connected through the StraitsX rail, with 174% YoY transaction growth and 2.5× growth in unique users.
AvaCloud Solved the Problem
One integration, two ecosystems, zero merchant friction.
StraitsX integrated directly with the existing GrabPay QR infrastructure. An Alipay+ user scans a GrabPay QR; the merchant processes the payment as they would any other local transaction. No new hardware, no onboarding, no training.
Behind the scenes, StraitsX runs the full stack on its own AvaCloud-managed Avalanche L1: real-time FX conversion, Purpose Bound Money for programmable conditional transfers, and 24/7 blockchain-based settlement in SGD. The end user never interacts with blockchain directly.
Merchants are shielded from foreign-currency risk. Funds arrive in local currency, instantly. The integration has been live since October 2024, and is now extending across more verticals, seasonal campaigns, and global corridors.
"With this collaboration, visitors to Singapore can now enjoy the convenience of using their preferred wallet when paying at any restaurant or retail merchant displaying the GrabPay QR.", Kell Jay Lim, Regional Head, GrabFin
The Flow
From scan to settlement, the path a payment takes.
An Alipay+ wallet, a GrabPay QR, and the StraitsX-operated Avalanche L1 in between. The user and the merchant both stay in their familiar interfaces; the cross-border plumbing happens onchain.

The Network
StraitsX sits inside Asia's institutional liquidity fabric.
Cross-border interoperability is not theoretical. It is already live between Singapore and Thailand, with Korea and Japan running on the same Avalanche standard via AvaCloud.

Avalanche L1 on AvaCloud
Your cross-border corridor could be running on this rail.
StraitsX proved that a regulated stablecoin on a dedicated L1 can connect entire wallet ecosystems without forcing merchants or users to change anything. The same AvaCloud-managed model is available to any payment institution building cross-border settlement infrastructure.
