SIR
Derivatives
SIR is a decentralized trading protocol designed for leveraged positions with a focus on long-term investing. Key features include a one-time fee for opening positions (no recurring funding costs), no liquidations, and no volatility decay (returns aren't eroded by market fluctuations). By eliminating these traditional risks and costs, SIR offers a sustainable way to maintain leveraged exposure over extended periods, making it ideal for investors seeking leveraged assets without the stress of daily fees, margin calls, or compounding price instability.
