Solstice Teams Up With Chainlink, Custody Giants Ahead of USX Stablecoin Debut

Quick Breakdown:

• Solstice partners with Chainlink, Ceffu, Copper, and Arcanum to power the upcoming USX stablecoin ecosystem.
• Chainlink offers cross-chain interoperability, data streams, and a planned Proof of Reserve for secure and transparent operations.
• Ceffu, Copper, and Arcanum strengthen settlement options, security, and token strategies for institutional-grade DeFi adoption.

Solstice Finance has entered a strategic partnership with Chainlink, Ceffu, Copper, and Arcanum to strengthen its infrastructure and market positioning ahead of the launch of its Solana-native USX stablecoin this September. The synthetic stablecoin and yield-generation protocol said the collaboration will enhance cross-chain compatibility, settlement efficiency, and institutional adoption.

Chainlink integration to power cross-chain stability

Chainlink will serve as Solstice’s official oracle provider, supplying key services such as its Cross-Chain Interoperability Protocol (CCIP) and Data Streams for sub-second settlement. The integration enables secure, zero-slippage cross-chain transactions and faster execution for USX. Solstice also plans to deploy Chainlink Proof of Reserve for transparent collateral verification. “This collaboration ensures the highest level of interoperability, security, and transparency across markets,” said Colin Cunningham, Global Head of Tokenized Asset Sales at Chainlink Labs.

Custody and market access backed by major players

Institutional settlement will be supported by Ceffu and Copper, both offering off-exchange solutions to minimize counterparty risk. Ceffu’s MirrorX will facilitate Binance settlements, while Copper will enable broader off-exchange settlements on centralized exchanges. Arcanum will assist with token design, economics, and go-to-market strategy to attract both crypto-native and institutional investors.

Solstice has already secured over $1 billion in assets staked across 9,000 validators and aims to position USX as a trusted, transparent stablecoin for DeFi and traditional finance. CEO Ben Nadareski described the partnership as a critical step in building a widely used stablecoin ecosystem as Solana enters “a period of remarkable growth.”

USX will launch later this month alongside Solstice’s YieldVault protocol, offering institutional-grade, delta-neutral yields for participants seeking stable returns.

Meanwhile, 0G, a modular AI-focused Layer 1 blockchain, has adopted Chainlink CCIP and Data Streams as its canonical cross-chain infrastructure, enabling secure token transfers, low-latency market data, and real-time AI-powered decentralized applications. 0G selected Chainlink CCIP for its proven track record of security and reliability in powering decentralized finance.
