- This integration will support automated payments and on-chain SGD-USD exchanges.
- XSGD and XUSD have processed more than $18 billion in on-chain transactions.
- StraitsX operates under MAS regulation and is exploring payments with Grab.
Singapore-based stablecoin issuer StraitsX plans to expand its Singapore dollar-backed XSGD and US dollar-backed XUSD onto the Solana blockchain in early 2026.
The move reflects a broader push to place regulated stablecoins at the center of high-speed blockchain settlement systems, especially for payments, digital trading, and emerging AI-driven use cases.
By leveraging Solana’s low-cost infrastructure and high throughput, StraitsX aims to make SGD and USD transactions more efficient across decentralized finance, institutional flows, and everyday payments.
This expansion also positions the company to meet rising demand for programmable money within native, composable software environments.
Solana integration package
The launch was announced in collaboration with the Solana Foundation and detailed in a blog post.
Once live, users will be able to settle transactions with XSGD and XUSD directly on Solana, taking advantage of faster confirmation times and lower transaction fees.
StraitsX says the integration brings multiple financial functions together on a single blockchain, covering centralized exchange support, decentralized liquidity pools, lending markets, and consumer payments.
The company views Solana as a fitting base layer to support complex payment flows that require speed and scalability without compromising reliability.
Demand from AI and trading
StraitsX says the expansion is designed to support growing usage from digital trading platforms and native AI applications.
Solana has seen rising adoption for x402-based payments, an interoperability standard that enables automated transactions between software agents.
Both XSGD and XUSD already support the x402 standard natively, and that capability will extend to Solana.
As a result, developers and institutions will be able to deploy automated payment use cases, including on-chain SGD-USD foreign exchange, automated market maker liquidity provisioning, lending protocols, and institutional-grade settlement flows.
On-chain volume and token data
XSGD is already available on several blockchains, including Ethereum, Polygon, Avalanche, Arbitrum, Zilliqa, Hedera, and XRP Ledger.
XUSD is currently available on Ethereum and BNB Smart Chain.
XSGD has a market capitalization of $13 million with a circulating supply of 16.7 million tokens, while XUSD has a market capitalization of $52 million.
Combined, the two stablecoins have processed more than $18 billion in on-chain transaction volume, underscoring their growing role in cross-chain payments and settlement activity.
Regulation and Grab partnership
StraitsX operates as a licensed Major Payment Institution under the Monetary Authority of Singapore’s stablecoin framework.
Both XSGD and XUSD have been recognized by MAS as compliant with the forthcoming stablecoin regulatory framework, according to the company’s white paper.
Separately, the firm has moved to explore consumer-facing applications.
Last month, Grab signed a memorandum of understanding with StraitsX to explore a Web3 settlement layer for Southeast Asia.
Subject to regulatory approvals, the initiative would allow Grab users to hold and spend XSGD and XUSD directly within the app, integrating digital wallets, programmable payments, and stablecoin clearing into everyday transactions.
