Smart Contracts

Smart contracts form the backbone of Vana's decentralized data economy by handling data registration, tokenization, rewards, and governance in a secure and transparent manner.

• Data Registry: The data registry is the main entry point for data in the Vana network.
• TEE Pool: The TEE Pool orchestrates TEEs in the Satya Network.
• DLPRewards: Smart contracts that implement the VRC-14 liquidity-based reward distribution system for Data Liquidity Pools, replacing direct VANA emissions with market-driven incentives that create deeper liquidity for data assets.
  • VanaEpoch: Manages the Vana epoch system using quarterly cycles, coordinating the timing of DLP performance evaluation and reward distribution across the ecosystem.
    DLPRegistry: Manages the central registry of all DLPs in the Vana ecosystem, tracking their registration status, VRC compliance verification, and eligibility for reward participation.
  • DLPPerformance: An oracle that stores off-chain calculated DLP performance scores and automatically distributes epoch rewards based on final scores submitted after each epoch ends
  • DLPRewardDeployer: Implements VRC-14's liquidity-based DLP incentives by converting VANA rewards into 90 daily tranches that purchase DLP tokens and add liquidity to DEX pools, triggered at random times by an off-chain oracle to prevent market manipulation.
  • DLPRewardSwap: A helper for the DLPRewardDeployer that manages the complex swap and liquidity operations needed to convert VANA rewards into optimized DLP token liquidity positions.
  • SwapHelper: A helper that manages the integration between Vana smart contracts and Uniswap protocols, handling swaps, quotes, and liquidity operations while abstracting away Uniswap's technical complexities.
• DataAccess: Core infrastructure for secure data storage, refinement, querying, and computation within the Vana network, enabling decentralized data processing through TEE-based execution environments.
  • DataRefinerRegistry: Registry for data refiners that define schemas and transformation instructions for processing raw data into structured formats.
  • ComputeEngine: Orchestrates compute job execution across TEE pools with automatic assignment, payment management, and job lifecycle tracking.
  • ComputeEngineTeePool: Manages a pool of TEE nodes configured for specific timeout durations and hardware types (CPU/GPU).
  • ComputeEngineTeePoolFactory: Factory contract for creating and managing different types of TEE pools based on job requirements.
  • ComputeInstructionRegistry: Registry for approved compute instructions with DLP-based approval system ensuring data security.
  • QueryEngine: Manages data access permissions and payments for querying refined data with revenue sharing between data owners and DLPs.
  • DataAccessTreasury: Treasury contracts for managing and distributing payments for data access and compute job execution.
• VanaPool: VanaPool is a decentralized staking protocol that allows users to stake VANA tokens into different entities, earning continuously compounded rewards based on each entity's APY while maintaining their share ownership through a dynamic shares system.
  • VanaPoolEntity: Manages yield-generating entities with configurable APY settings and reward distribution mechanisms.
  • VanaPoolStaking: Enables users to stake and unstake VANA tokens across different entities using a share-based accounting system.
  • VanaPoolTreasuty: A secure vault contract that holds staked VANA tokens and manages their distribution when users unstake.
• Data Liquidity Pool & DLP Token: A DataDAO's implementation of how to tokenize data in the Vana network.
• Multicall3: Enables batching multiple smart contract calls into a single transaction to optimize gas usage and execution efficiency.
• Multisend: Allows batch transfers of tokens or ETH to multiple addresses in a single transaction, reducing gas costs for bulk operations.
• DLPRoot - deprecated - these contracts have been migrated to VanaPool and DlpRewards contracts
  • DLPRootEpoch - deprecated: Handles epoch-based operations including creation, finalization, and reward distribution for DLPs across time periods.
  • DLPRootCore - deprecated: Manages the DLP lifecycle including registration, verification, and stake management with eligibility thresholds.
  • DLPRootStaking - deprecated: Manages staking functionality including stake creation, withdrawal, migration, and reward.
  • DLPRootMetrics - deprecated: Calculates performance ratings and rewards for DLPs, determining top performers based on stake amounts and custom metrics.
  • DlpRootTreasuries - deprecated: Manages staked and reward VANA tokens through separate treasuries for staking and reward distribution.
