Introduction and summary: I present a hypothesis on Downside Liquidity or liquidity pools for short positions in EVM environments and propose a basic implementation in Solidity oriented to Ethereum. The central idea is to design pools that supply liquidity specifically to cover the downside of short positions, allowing liquidity providers to earn returns by taking on asymmetric risk and short traders to access efficient collateral.
Concept and operation: A short liquidity pool is a shared fund where providers deposit assets to back short positions. In return, they receive shares representing their exposure to losses on the downside of the market. Shorts take collateralized loans, accepting that losses are drawn from the pool when the price rises. A reliable oracle, clear margin and liquidation rules, and mechanisms for distributing fees and rewards to liquidity providers are needed.
Key mechanisms: Price oracle for marking positions, margin and collateral calculation, liquidity tokens or shares to represent participation, risk management with exposure limits per asset, and automated liquidation processes that minimize slippage. It is also important to design incentives for providing liquidity during low-demand periods and for orderly withdrawal in extreme markets.
Advantages and challenges: Advantages include greater capital efficiency for traders taking short positions and new yield opportunities for liquidity providers. Relevant challenges are tail and cascade risk in extreme markets, oracle dependency, regulatory complexity, and the need for robust valuation and liquidation models.
Simplified implementation proposal in Solidity: Below is a very basic skeleton that exemplifies concepts such as liquidity deposit, withdrawal, and opening short positions. It is a conceptual starting point and not a production-ready solution. Comments and audits are essential before any deployment.
// SPDX-License-Identifier: MIT pragma solidity ^0.8.0 interface IOracle { function getPrice(address token) external view returns (uint256); } contract ShortLiquidityPool { address public owner; IOracle public oracle; mapping(address => uint256) public liquidityShares; uint256 public totalLiquidity; constructor(address _oracle) { owner = msg.sender; oracle = IOracle(_oracle); } function deposit() external payable { require(msg.value > 0); uint256 shares = msg.value; liquidityShares[msg.sender] += shares; totalLiquidity += shares; } function withdraw(uint256 shares) external { require(liquidityShares[msg.sender] >= shares); uint256 amount = shares; liquidityShares[msg.sender] -= shares; totalLiquidity -= shares; payable(msg.sender).transfer(amount); } function openShort(address token, uint256 size) external { uint256 price = oracle.getPrice(token); require(totalLiquidity >= size * price / 1e18); // simplified logic for opening a short // in a real design, collateral, fees, and time window parameters would be managed } }
Production considerations: Integrate a decentralized and redundant oracle, add exposure limits, fee mechanisms and dynamic commissions, stress tests, and security audits. Implement unit and integration tests with extreme scenarios to validate the robustness of the system.
Invitation to the community: If this idea is interesting, it would be ideal to integrate it into a broader project with research, simulations, and audits. Collaboration between developers, economists, and security auditors is key to bringing such a concept to production.
