Solstice Joins Copper's Stablecoin Rewards Program
Solstice is joining Copper's stablecoin rewards program, giving institutional clients access to yield on USX (a Solana-based synthetic stablecoin) within Copper's custody environment.
17 March 2026, London, UK --- Solstice will be joining Copper’s stablecoin rewards program, enabling institutional access to yield exposure on USX, a Synthetic stablecoin on Solana, directly within Copper’s secure custody environment.
This expanded integration establishes Copper’s ClearLoop as the custody and collateral management backbone for Solstice’s yield program, making space for compliant capital deployment and operationally streamlined access to USX for institutional participants.
What is USX?
USX is Solstice's Solana-native synthetic stablecoin, pegged 1:1 to USD and fully collateralized by USDC and USDT, with solvency verified via attestation.solstice.finance. It is the largest Solana-native stablecoin by TVL.
Through the Stablecoin Rewards Program, institutional clients holding USX in Copper custody will receive yield sourced from Solstice's YieldVault -- a regulated, delta-neutral strategy operated by a BVI-licensed Approved Manager with a three-year institutional track record: 13.96% net IRR, 21.5% performance in 2024, and zero months of negative returns since inception. Clients receive the yield without needing to interact with DeFi protocols or manage positions directly.
Institutional-Grade Access to DeFi Yield
Institutions seeking stablecoin yield are often constrained by compliance mandates and internal governance processes that limit direct DeFi participation. By delivering YieldVault-sourced rewards inside Copper's institutional custody framework, those barriers are removed.
Assets remain under the safeguard of Copper's custody environment, and institutions can participate in the rewards program with compliant risk controls and operational segregation standards in place.
