# HIP-15: Add SOL to Horizon Futures
Add SOL market to Horizon Futures to expand trading options and incentivize more activity on the platform.
**Type:** Horizon Improvement Proposal
**Date:** June 22th, 2024
**Status:** Completed
Summary
This HIP proposes to add Solana (SOL) to the Horizon Futures platform to increase the options available to traders and boost trading volume. By introducing SOL to the Futures market, we aim to enhance the platform's appeal and provide traders with more opportunities to diversify their trading strategies.
#### Specification
Add Solana (SOL) market on Horizon Futures and set the system parameters as below:
* makerFeeOffchainDelayedOrder: 0.00015,
* takerFeeOffchainDelayedOrder: 0.0006,
* offchainDelayedOrderMinAge: 1,
* offchainDelayedOrderMaxAge: 30,
* maxLeverage: 27.5,
* maxMarketValue: 14800,
* maxFundingVelocity: 36,
* skewScale: 2100000,
* offchainPriceDivergence: 0.10,
* liquidationPremiumMultiplier: 1.5625,
* liquidationBufferRatio: 0.0075,
* maxPD: 0.001602,
* maxLiquidationDelta: 0.000801
#### Motivation
The primary motivation behind this proposal is to expand the range of assets available for trading on Horizon Futures, thereby providing a more comprehensive futures exchange. By offering an attractive and diverse set of markets, we aim to attract more traders to the platform, increase trading activity, and enhance overall market liquidity.
Given that zSOL, the synthetic equivalent of SOL on Horizon Protocol, ranks fourth by market cap among zAssets, it's the optimal choice for addition as the next Futures asset based on trader interest.
#### Considerations
* Global Debt Pool Impact: Adding new assets to Horizon Futures will introduce increased volatility and potentially impact the global debt pool. Therefore, assets should be added gradually to ensure the platform's stability and manage risk effectively.
#### Post-Implementation Evaluation
Upon the addition of SOL to Horizon Futures, an evaluation will be conducted to assess the market's performance and impact. Key metrics such as trading volume, user activity, and market stability will be analyzed to inform future decisions and strategy adjustments. The aim is to continue to add more markets to Horizon Futures while maintaining an active risk management strategy.
