Equation represents a decentralized perpetual contract built on Arbitrum, introducing the innovative BRMM model allowing up to 200x leverage to traders and Liquidity Providers. The launch of Equation has brought significant advancements to the world of decentralized finance (DeFi) and perpetual trading.

Following the tremendous growth of DeFi with the rise of automated market makers like Uniswap in the spot market, Equation was developed to bridge the gap between spot and perpetual markets. Unlike the spot market, which has lower trading volumes compared to centralized exchanges for perpetual contracts, Equation's BRMM model has revolutionized perpetual trading by offering liquidity providers and traders leverage limits of up to 200x. This has improved capital efficiency for liquidity providers while expanding possibilities for traders.

The introduction of Equation V2 in December 2023 has further refined the algorithm, enhancing market-making efficiency and risk-hedging capabilities for liquidity providers. The new version eliminates the Risk Buffer Fund, which was deemed less effective in protecting liquidity providers from substantial losses.

Equation V2 brings several improvements to the system. These include accurate passive positions for liquidity providers, multiple fee and leverage tiers, and the elimination of the Risk Buffer Fund. By offering a precise passive position system, LPs can better manage their risks in real-time. Additionally, the multiple fee levels ensure fair compensation for LPs based on different risk levels, setting a strong foundation for future market expansion.

Importantly, Equation V2 emphasizes the role of liquidity providers within the BRMM model. LPs facilitate trading activities on behalf of traders, holding passive positions relative to the total positions of all LPs while maintaining liquidity equivalence across the network. Sources of income for LPs include trading fees, funding fees, and liquidity mining rewards.

Despite the potential for profitability, liquidity providers face risks related to their net positions when holding passive positions. It is recommended that LPs carefully manage leverage levels and employ effective hedging strategies to mitigate these risks. Equation V2 provides a comprehensive fee and leverage schedule to guide LPs in setting appropriate trading parameters.

Overall, Equation V2 enhances the capabilities of liquidity providers and traders within the DeFi ecosystem. The tokenomics of Equation, including the native EQU token and Equation Founders Club (EFC) NFT, play a crucial role in incentivizing community participation and rewarding stakeholders.

The recent developments within the Equation ecosystem, including the successful audit of the smart contract and the official testnet launch, highlight the commitment to technical development, community building, and core principles of security and innovation. As Equation continues to evolve, it remains dedicated to empowering users and shaping the future of decentralized finance.
