About the company

Solstice is building institutional-grade DeFi infrastructure on Solana. Backed by Deus X Capital — a multi-strategy digital asset group with a three-year track record of 13.96% net IRR and zero negative months — Solstice bridges traditional finance and decentralised markets through USX, the institutional settlement layer on Solana. Our products serve institutional allocators like Galaxy Digital, Susquehanna, Bitcoin Suisse, and RockawayX, while remaining fully permissionless for DeFi users. We are a remote-first team with regulatory footholds across the EU (MiCA-notified), BVI, and Singapore.
