Yield Farming Protocol Smart Contract (Clarity)

This smart contract implements a yield farming and token staking protocol on the Stacks blockchain. It allows users to stake two tokens (primary and secondary) into a farming vault to earn yield rewards based on a time-weighted share allocation model. The contract includes:

• Token Compatibility: Works with any token implementing the defined fungible-token-trait.
• Minimum Deposit Enforcement: Deposits must meet a predefined MIN_DEPOSIT_AMOUNT threshold.
• Share Allocation Mechanism: Uses a custom find-minimum function to fairly allocate shares based on deposits and current vault reserves.
• Lockup Period: Users must wait LOCKUP_DURATION (~24 hours in blocks) before withdrawing their staked tokens and rewards.
• Yield Calculation: Based on stake amount, duration, and the current yield-rate.
• Vault Management: Tracks total reserves, outstanding shares, and accumulated fees per vault.
• Admin Functions: Includes admin transfer, yield rate adjustment, and protocol pause/resume control.
• Security Checks: Ensures valid token contracts, prevents re-entry or duplicate deposits, and enforces access control.

Overall, this contract offers a secure and flexible infrastructure for decentralized yield farming with built-in administrative oversight and automated reward mechanics.
