Solayer has launched its public testnet for Margin Trade, a Solana-based perpetual futures trading platform that supports unified margin trading across cryptocurrencies, commodities, and equities. Developed by Solayer Labs with former Citadel and Kraken traders, the platform aims to integrate digital and traditional financial instruments in a single on-chain environment. Initially available in private beta, Solayer is now expanding access to users on its waitlist. The platform features a single-collateral system for enhanced capital efficiency and real-time execution. At launch, it supports crypto perpetual contracts and commodity contracts for gold, silver, and crude oil, along with the synthetic index MT500, which tracks U.S. stock market performance. Solayer plans to expand its offerings to include individual stocks and volatility products, alongside introducing trading competitions and referral programs to boost user engagement.
