# Periphery Venus Protocol periphery contracts extend core protocol functionality with auxiliary features for advanced DeFi operations. These contracts integrate with the Venus Comptroller and vToken markets to provide atomic, gas-efficient operations. ## Overview The Venus periphery consists of specialized smart contracts designed to streamline complex DeFi operations: * [**RelativePositionManager**](/technical-reference/reference-periphery/relative-position-manager.md) - Orchestrate the full lifecycle of Venus Trade positions, from activation and opening to proportional closing and deactivation * [**LeverageStrategiesManager**](/technical-reference/reference-periphery/leverage-strategies-manager.md) - Enter and exit leveraged positions atomically using flash loans * [**SwapHelper**](/technical-reference/reference-periphery/swap-helper.md) - Execute backend-authorized token swaps with signature verification ## Key Features * Flash loan-based atomic execution * EIP-712 signature verification for authorized operations * EIP-1153 transient storage for efficient callback state management * Comprehensive account safety validation * Slippage protection on all swap operations ## Deployment Periphery contracts are currently deployed on BNB Chain Mainnet. See [Deployed Contracts](/deployed-contracts/periphery.md) for addresses and deployment information. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
