Grab & StraitsX Explore Stablecoin Payments in Southeast Asia

Grab and StraitsX Partner for Web3 Payments in Southeast Asia

Grab, Southeast Asia’s largest super-app, is deepening its involvement in stablecoin infrastructure through a new exploratory agreement with StraitsX, a Singapore-based stablecoin issuer. The two companies announced on Tuesday that they have signed a memorandum of understanding (MOU) to develop a Web3-enabled settlement layer that brings digital asset wallets, programmable payments, and stablecoin-based clearing to everyday consumer experiences.

Potential Stablecoin-Powered Payment System

If approved by regulators and implemented, the system would allow Grab users to hold and spend StraitsX-issued tokens like XSGD and XUSD directly within the app, which is available in Singapore, Malaysia, Indonesia, Thailand, Vietnam, the Philippines, Cambodia, and Myanmar. With Grab’s extensive reach in Southeast Asia, this move could significantly reshape how cross-border retail payments operate in the region.

Alleviating Fragmented and Costly Payments

“Southeast Asia is one of the world’s fastest-growing digital economies, but payments remain fragmented and costly,” said Tianwei Liu, co-founder and CEO of StraitsX, adding that the collaboration will accelerate the growth in the region’s digital economy.

Grab's History with Stablecoins

This is not the first foray into the stablecoin space for Grab. The company has tested blockchain-based rewards, collaborations with Web3 wallets, and limited pilots to assess user readiness. In 2023, Grab partnered with stablecoin issuer Circle to pilot Web3 customer experiences in Singapore. This allowed users to set up a blockchain wallet, earn rewards, and use non-fungible token (NFT) vouchers.

Expanding GrabPay Functionality

In 2024, Grab began allowing users to top up their GrabPay wallets using crypto and stablecoins. On May 6, Grab partnered with Natix, a decentralized physical infrastructure network (DePIN) operating in Solana, to combine blockchain-based mapping with Grab’s camera hardware and mapmaking technology.

Broader Blockchain Ambitions

While Grab is not new to stablecoins and blockchain, this deal signifies an escalation from its prior experiments. It signals a much broader ambition, namely, selecting a default on-chain settlement rail that could underpin all major markets where Grab operates. Instead of simply utilizing stablecoins, Grab is exploring the fundamental question of which stablecoin infrastructure should power its future payment flows.

Improving Cross-Border Payments

“Grab sees potential for Web3 technologies to improve cross-border retail payments while providing a familiar experience for users,” said Kell Jay Lim, the head of Grab Financial. He stated that they will work with StraitsX to address some of these challenges for their merchants and consumers.

Web3 Wallet Integration within Grab App

At the core of the proposal is a Web3 wallet embedded inside the Grab application. This would enable users to make cross-border payments, convert between fiat and stablecoins, and even receive funds from external Web3 wallets. Additionally, merchants will receive Web3-compatible wallets offering programmable settlement, on-chain treasury tools, and real-time clearing. This could lower fees compared to card networks and alleviate liquidity challenges.

Regulatory Approvals Needed

While the initiative is promising, its success hinges on securing regulatory approvals across the jurisdictions where Grab operates, as each implements different supervision models for stablecoins, e-money, and digital assets. However, the intention is clear: to construct an interoperable settlement layer to replace the current siloed, high-cost cross-border flows.
