Rails, a provider of institutional crypto derivatives, has launched an "Institutional-Grade Vault" on the Stellar Network. This new product enables brokers and fintech firms to engage in crypto perpetual contract trading via a unified backend, with options trading set to debut in Q2 2026. The vault's design separates trade matching from fund custody, storing client assets in an audited smart contract vault on Stellar while using a centralized matching engine. Profit and loss data is submitted to the blockchain every 30 seconds for independent verification, aiming to minimize counterparty and operational risks.
