Singapore’s StraitsX will expand XSGD and XUSD stablecoins to Solana

• The integration will support automated payments and onchain SGD-USD exchange.
• XSGD and XUSD have processed more than $18 billion worth of onchain transactions.
• StraitsX operates under MAS regulation and verifies payments with Grab.

Singapore-based stablecoin issuer StraitsX plans to roll out its Singapore-backed XSGD and US dollar-backed XUSD on the Solana blockchain by early 2026.

This move reflects a broader push to put regulated stablecoins at the center of high-speed blockchain settlement, particularly for payments, digital commerce and emerging AI-based use cases.

By leveraging Solana’s low-cost and high-throughput infrastructure, StraitsX aims to make SGD and USD transactions more efficient, across both decentralized finance, institutional flows and everyday payments.

The expansion also positions the company to meet the increasing demand for programmable money in interoperable, software-based environments.

Solana integration plans

The launch was announced in collaboration with the Solana Foundation and in a Blog post on Tuesday explained in more detail.

Once online, users can transact directly with XSGD and XUSD on Solana, benefiting from faster settlement times and lower transaction fees.

StraitsX explained that the integration brings together multiple financial functions on a single blockchain, which includes centralized exchange support, decentralized liquidity pools, credit markets and consumer payments.

The company sees Solana as a suitable base layer to support complex payment flows that require speed and scalability without compromising reliability.

Demand from AI and Commerce

StraitsX said the expansion is designed to support increasing usage by digital trading platforms and AI-native applications.

Solana is seeing growing adoption of x402-based payments, an interoperability standard that enables automated transactions between software agents.

Both XSGD and XUSD already support the x402 standard natively, and this feature will also be extended to Solana.

This will allow developers and institutions to implement automated payment applications, including onchain SGD-USD FX, automated liquidity provision from market makers, lending protocols and institutional settlement processes.

Onchain volume and token data

XSGD is already available on multiple blockchains including Ether, Polygon, Avalanche, Arbitrum, Zilliqa, Hedera and the XRP Ledger.

XUSD is currently available on Ethereum and BNB Smart Chain.

XSGD has a market cap of $13 million and a circulating supply of 16.7 million tokens, while XUSD has a market cap of $52 million.

Together, the two stablecoins have processed more than $18 billion in onchain transaction volume, highlighting their growing role in cross-chain payments and settlement activities.

Regulatory and Grab Partnership

StraitsX operates as a licensed major payment institution under the stablecoin framework of the Monetary Authority of Singapore.

Both XSGD and XUSD have been recognized by the MAS as compliant with the upcoming stablecoin regulatory framework, according to their white papers.

Separately, the company has focused on exploring consumer-oriented applications.

Last month, Grab signed an exploratory memorandum of understanding with StraitsX to develop a Web3-enabled settlement layer for Southeast Asia.

Pending regulatory approval, the initiative would allow Grab users to hold and spend XSGD and XUSD directly in the app by integrating digital wallets, programmable payments and stablecoin clearing into daily transactions.
