Safer leverage for
Long-term investors
What is SIR?
SIR offers a new way to take leverage in DeFi: compounding exposure without the usual drag. Instead of funding or maintenance fees that slowly eat returns, SIR charges one fixed fee only when you open a position.

The protocol maintains its own internal liquidity pools, letting it update balances on-chain without the constant rebalancing trades that cause volatility decay elsewhere.
As prices move, leverage stays mechanically constant, so positions follow their target payoff without bleeding value to fees or decay. The result is a safer, more efficient path to amplified, long-term returns.
SIR: a Fee Paying Token
SIR is the native token of the SIR protocol. Unlike most DeFi tokens, the SIR token issuance is immutable and part of the core protocol. The SIR token is designed to have strong fundamentals, rewarding its stakers with a share of the protocol's generated fees.
The token is primarily distributed to liquidity provider at a rate of 2,015 million tokens per year, in perpetuity. To maintain a proportional stake in the protocol, providing liquidity is necessary.

Permissionless & Trustless
- 1
SIR is designed as a DeFi primitive, focusing on being maximally trustless and permissionless. Like Uniswap, anyone can create a vault, specifying a pair of tokens and a leverage ratio.
- 2
The protocol runs on immutable smart contracts with fixed parameters, eliminating risks from unexpected changes. After its beta phase, SIR's unstoppable code will be completely immutable, living on Ethereum forever.
- 3
This trustless architecture, combined with reliable price oracles, establishes SIR as a fundamental money lego in the DeFi ecosystem.
Gentlemen & Apes

Gentlemen provide liquidity to the protocol. They earn fees for doing so, and on selected vaults, also rewards in the native token SIR. Their LP positions are tokenized in the form of an ERC-1155 called TEA.

Apes choose which pair they want to long, and what leverage. They pay upfront fees for minting and burning, but not while holding their positions. APE is a leveraged ERC-20 token that can be transferred and used in other protocols.
