Smart Contract Architecture
DeepFlow Finance is built on a modular, upgradeable smart contract system designed for scalability, security, and composability. The architecture is purposefully lean and extensible — enabling DeepFlow to evolve with user needs, integrate with external DeFi protocols, and support new collateral types without compromising safety.
1. Vault Contract (Lending Pool Logic)
● Manages user deposits and withdrawals
● Pools capital for specific asset categories
● Issues yield to lenders at end of loan cycles
● Handles liquidity provisioning for borrower payouts
● Supports multi-asset lending pools (via ERC-4626 standard)
Key Features:
● Capital segmentation per collateral type
● Interest accrual logic baked into vault
● Emergency pause and withdraw mechanism
● Pools capital for specific asset categories
● Issues yield to lenders at end of loan cycles
● Handles liquidity provisioning for borrower payouts
● Supports multi-asset lending pools (via ERC-4626 standard)
Key Features:
● Capital segmentation per collateral type
● Interest accrual logic baked into vault
● Emergency pause and withdraw mechanism
2. Loan Engine Contract
● Processes loan requests and repayment logic
● Calculates loan terms using AI rate engine outputs
● Applies origination, renewal, and liquidation fees
● Executes collateral lock/unlock on loan open/close
● Syncs daily with valuation oracle
Key Features:
● Fixed-term enforcement
● Flexible LTV and interest model
● Integrates auto-renewal for borrowers
● Calculates loan terms using AI rate engine outputs
● Applies origination, renewal, and liquidation fees
● Executes collateral lock/unlock on loan open/close
● Syncs daily with valuation oracle
Key Features:
● Fixed-term enforcement
● Flexible LTV and interest model
● Integrates auto-renewal for borrowers
3. Oracle & Valuation Module
● Fetches price data from Chainlink, Uniswap TWAP, and custom APIs
● Calculates asset risk score using off-chain AI computation
● Feeds real-time valuation to Loan Engine
● Updates daily to minimize manipulation or stale pricing
Key Features:
● Altcoin pricing via decentralized oracles
● TWAP smoothing and deviation detection
● Calculates asset risk score using off-chain AI computation
● Feeds real-time valuation to Loan Engine
● Updates daily to minimize manipulation or stale pricing
Key Features:
● Altcoin pricing via decentralized oracles
● TWAP smoothing and deviation detection
4. Liquidator Contract
● Triggers auctions or forced sales for defaulted loans
● Calculates repayment priorities for lenders
● Distributes leftover value back to borrower (if applicable)
● Includes whitelist of third-party auction houses
Key Features:
● Batch liquidations for gas efficiency
● Proceeds routing to vault and borrower
● Optional DAO-curated liquidator set
● Calculates repayment priorities for lenders
● Distributes leftover value back to borrower (if applicable)
● Includes whitelist of third-party auction houses
Key Features:
● Batch liquidations for gas efficiency
● Proceeds routing to vault and borrower
● Optional DAO-curated liquidator set
