SIR Review 2026: Leverage Without Liquidations or Funding

SIR is a decentralized trading protocol for leveraged positions aimed at long-term holders. Its tagline is "Leverage You Can Sleep On." The pitch is a one-time fee, no funding rates and no liquidations, which it describes as the best of perps and options without the worst of either.

DefiLlama files SIR under derivatives and lists it on Ethereum, MegaETH and Hyperliquid. It has been tracked since February 2025 and lists two audits. TVL is about $90,312 and has no token listed on DefiLlama, though the homepage refers to SIR rewards and staking.

The design is unusual, and the project itself notes that key benefits apply only up to a liquidity-determined price threshold. With a small TVL, that threshold is a point to watch.

SIR is built around three roles. Liquidity providers deposit assets that back leveraged positions. Traders take leverage by paying a one-time fee when they open a position. Stakers hold SIR to earn a share of protocol revenue.

The project says this structure removes the usual costs of perps. There are no funding rates and no liquidations. It also aims to avoid volatility decay, where leveraged tokens lose value in choppy markets, and to keep leverage constant so gains compound as price rises.

These properties come with a limit. The homepage says constant leverage and no volatility decay hold up to a price threshold determined by liquidity, which it calls best-effort convexity. In practice, deeper liquidity should widen the range where the design works as described.

The main fee is a one-time charge when opening a leveraged position. The project says there are no funding rates and no recurring holding costs. The exact size of the opening fee is not public.

Liquidity providers earn fees and SIR rewards, and stakers earn protocol revenue. Users should check the docs or the app for current fee levels before opening a position. Network gas costs on the chosen chain also apply.

DefiLlama lists two audits for SIR and the site links to an audits page, but the project does not name the auditors or findings. Check the audit reports directly. As with any smart-contract protocol, bugs, oracle issues and economic design flaws remain possible, and public sources mention no insurance or guarantees.

The protocol is non-custodial in the usual DeFi sense, but users should confirm this in the docs. Liquidity providers carry risk of drawdowns, and traders depend on liquidity depth for the stated benefits. The project does not mention hacks or incidents. Leveraged products are high risk and may be restricted in some jurisdictions, so check your local rules.

SIR is for long-term holders who want leveraged exposure without managing margin or paying ongoing funding costs, and for liquidity providers comfortable with experimental DeFi risk. It is not suited to beginners or anyone who cannot afford to lose funds.
