On April 29, Solstice Labs, supported by Deus X Capital, announced that it will launch interest-bearing synthetic stablecoin USX and native staking protocol on Solana blockchain this summer. As an important innovation of Solana ecology, USX dynamically adjusts interest rates through algorithms (basic annualized 3.2% + dynamic incentives), combines the dual mechanism of "liquidity mining + governance voting" to attract institutional funds, and uses Chainlink and Pyth Network dual price feeds to ensure currency value stability. The project white paper shows that USX will be deeply bound to the Solana ecological Meme coin liquidity pool, and users can get PEPE, TRUMP and other popular tokens for staking. It is worth noting that XBIT decentralized exchange platform has taken the lead in connecting to the USX/USDT trading pair, with a stable slippage rate of 0.08%, becoming one of the first decentralized trading platforms (DEX) to support this asset1. USX: Reconstructing the Technology and Ecological Logic of StablecoinsThe USX launched by Solstice Labs breaks the single model of traditional collateral stablecoins and realizes a closed value loop through cross-chain arbitrage and dynamic incentives: Income mechanism innovation: The base interest rate is anchored to the USDC lending rate (3.2%) on the Solana chain, and the dynamic incentive of liquidity pool contribution is superimposed. Institutional users can participate in ecological governance voting by staking USX to obtain dual rights of income and governance; Price stability guarantee: Adopting cross-chain oracle dual protection, Chainlink aggregates off-chain data to ensure fair prices, and Pyth Network provides real-time quotes on the chain to form an abnormal fluctuation circuit breaker mechanism to control the risk of de-anchoring at 0.05%; Deep ecological integration: Cooperation with 20+ head Meme coin projects in the Solana ecosystem, users staking USX can automatically access the liquidity mining pools of tokens such as PEPE and TRUMP, realizing the linkage of stablecoins and hot assets.Solstice Labs CEO said in a statement that USX's goal is to become the "stablecoin connector of the Solana ecosystem", lowering the threshold for DeFi participation through technological innovation, and allowing institutions and retail investors to share the benefits of the ecosystem2. XBIT: Technical Adaptation to Build Efficient Trading ScenariosAs one of the first decentralized trading platforms to support USX, the technical architecture of XBIT decentralized exchange platform forms deep synergy with USX: Trading efficiency advantage: The self-developed distributed ledger system supports 2000+ transactions per second, and with the automatic clearing technology of smart contracts, the USX/USDT transaction slippage rate is stable at 0.08%, which is 60% lower than the industry average, providing protection for high-frequency trading and institutional arbitrage; Asset security system: Adopting the "95% cold wallet offline storage + 5% hot wallet dynamic position adjustment" solution, through CertiK full-link security audit, user assets are fully managed in personal encrypted wallets to avoid centralized risks; Cross-chain interoperability: Based on the underlying optimization of Solana chain, XBIT has achieved asset interoperability with Ethereum and BNB Chain. In the future, it will support the seamless flow of USX in the multi-chain ecosystem and expand its application scenarios. XBIT decentralized trading platform revealed that the team has been deeply involved in the Solana ecosystem for 18 months. This access to USX is the first in-depth cooperation between the two parties in the field of "stablecoin + decentralized trading". In the future, more technical exploration will be carried out around institutional-level liquidity solutions3. Market impact: opening a new paradigm of stablecoin and DEX collaborationThe launch of USX coincides with the outbreak of the Solana ecosystem. According to DeFi Pulse data, the scale of stablecoins on the Solana chain reached US$12 billion in Q1 2025, a year-on-year increase of 180%, showing the market's strong demand for stable assets on the chain. USX's "interest-bearing + mining + governance" compound mechanism is expected to attract traditional financial institutions to enter through compliant platforms such as XBIT, and promote the deep integration of institutional funds and the crypto ecosystem. Industry analysts pointed out that XBIT took the lead in supporting USX, reflecting its ability to deeply deploy in the Solana ecosystem. At present, XBIT has aggregated 70% of the Meme coin liquidity of the chain, processing more than 800,000 transactions per day, becoming a key hub connecting mainstream assets and emerging ecosystems. With the launch of the USX pledge agreement, XBIT users can realize the full process of "stablecoin interest. Meme coin mining-cross-chain transactions" on the same platform, significantly improving the efficiency of fund use. The cooperation between Solstice Labs and XBIT marks the deep synergy between stablecoin innovation and decentralized trading platforms. USX has solved the problem of single income of traditional stablecoins through technological breakthroughs, and XBIT's infrastructure support has provided it with a landing trading scenario. Under the trend of compliance and institutionalization of the crypto market, this "technological innovation + ecological adaptation" model may become an important direction for the future development of the industry.
