About XStable
XStable is an onchain gold and foreign-exchange venue built on Solana that matches through a central limit order book and settles in stablecoins, offering contracts on spot metals and major currency pairs to traders who want to bypass brokers and to automated programs that need round-the-clock liquidity. Friction in traditional metals and FX sits in clearing: quotes come from fragmented brokers, markets close at weekends and on holidays, margin and liquidation rules are set unilaterally by the venue, and users cannot verify fills or reserves.
XStable puts the order book onchain so prices and depth are publicly readable, settles fills instantly in stablecoins such as USDC, and keeps positions and margin auditable, with AI modules handling opportunity detection, risk measurement and order routing. On 8 September 2026 the platform connected to Sui Network, adding Sui wallet support and USDC deposits and withdrawals and bringing gold, silver, platinum and FX pairs into that ecosystem, giving it a two-chain footprint across Solana and Sui; the same integration is aimed at autonomous agents that operate outside banking hours. It is in public beta with gold and silver CFDs, its site shows XAU/USD near USD 4,224, and it reports handling more than USD 10 billion of volume per day.
In 2025, XStable was founded in Palo Alto, California, and began building a precious metals and FX perpetuals trading platform based on a central limit order book (CLOB).
On January 20, 2026, XStable was selected for the Solana Solaris Accelerator 2026 and announced multi-million-dollar funding led by Singapore and Silicon Valley investors.
On September 8, 2026, XStable's integration with Sui Network went live, supporting perpetual contracts for XAUUSD, XAGUSD, XPTUSD, and XPDUSD, with Sui Wallet connection and USDC deposits/withdrawals in a non-custodial setup.
On September 10, 2026, XStable officially announced its partnership with Sui Network, entering the Sui ecosystem.
On September 22, 2026, XStable completed a seed round with investors including YZi Labs, Sui Foundation, Taisu Ventures, and CatcherVC; the company said cumulative funding reached several million dollars.
XStable closed three institutional investments during 2026: a strategic round from Amber Group, a strategic round from KuCoin Ventures, and investment from YZi Labs through EASY Residency Season 4, alongside selection for the Solana Solaris Accelerator 2026.
XStable went live on Sui on September 8, 2026 and announced the Sui partnership on September 10, bringing perpetual contracts on gold, silver, platinum and palladium plus FX pairs to the network, with Sui Wallet connectivity and USDC deposits and withdrawals, all settled in stablecoins. The platform had been running in public beta on Solana with an on-chain central limit order book.
Future strategy and roadmap: After landing on Sui in September, XStable plans to widen coverage of gold, silver, platinum and palladium perps and FX contracts, and turn collateral and risk parameters into programmable modules that institutions can plug into. Building on its Solana on-chain order book and dual Sui chain, it will expand more RWA categories and pursue exchange listings and partnerships brought by backers such as Amber Group and KuCoin Ventures.
The core team of XStable comprises professionals with backgrounds in artificial intelligence, blockchain, and financial engineering, operating in a distributed manner across functions including algorithm research, smart contract development, risk modeling, and ecosystem operations. The founding team was assembled in the early stages of the project, with key members coming from well-known institutions in quantitative trading, AI infrastructure, and decentralized protocol development. Team leads hold degrees in computer science or financial engineering and previously served in technical or research management roles at global technology companies and blockchain projects, where they directed the design of algorithmic mechanisms and system architecture for stablecoin protocols. The research team consists of researchers with backgrounds in mathematics, statistics, and machine learning, focusing on the construction of pricing models and risk control frameworks. The engineering team is responsible for the development and maintenance of core protocols and on-chain modules, with members possessing years of experience in smart contract and distributed systems development. The project also maintains an advisory group composed of industry practitioners with hands-on experience in crypto economics, payments, and regulatory technology, providing guidance on technical and compliance matters. The overall team remains lean, emphasizing cross-functional collaboration and a remote-first working culture.
XStable charges a 0.008% holding fee per 8 hours on leveraged positions such as XAU/USD, calculated on the position notional and deducted each settlement cycle.
