SpotManager

Inherits: Initializable, OwnableUpgradeable, ISpotManager

Author: Logarithm Labs

SpotManager is a dedicated smart contract that manages spot positions for a trading strategy, enabling it to buy or sell assets on a decentralized exchange (DEX) or other spot market. This manager operates in tandem with a basis strategy, allowing it to adjust the spot position dynamically based on the strategy’s target exposure. The primary objective is to provide liquidity for the basis trade, maintaining optimal spot exposure relative to the short hedge position.

SpotManager is an upgradeable smart contract, deployed through the beacon proxy pattern.
