# Technical Integration Guide

### Overview

KodiakFarm is an advanced staking protocol that implements a dynamic reward system with time-locked staking mechanisms. The protocol enables users to stake ERC20 tokens and earn multiple reward types simultaneously, with rewards amplified through a duration-based multiplier system. This implementation focuses on flexibility, security, and capital efficiency through its sophisticated architecture:

* Dynamic Multi-Token Reward System: Supports multiple reward tokens that can be added or modified post-deployment
* Time-Weighted Multipliers: Rewards scale with lock duration, incentivizing longer-term commitment
* Advanced Security Architecture: Multi-layered access control system with distinct roles and permissions
* Adaptive Reward Management: Intelligent reward rate adjustment based on token availability and distribution metrics
* Risk Mitigation Features: Comprehensive safety controls including emergency withdrawals, staking caps, and granular pause mechanisms
* Capital Efficiency: Optimized reward distribution with configurability for different token economics models

#### Technical Details

**Initialization and Setup**

1. **Deployment Flow**
   * Deploy the contract through the FarmFactory
   * Initialize with owner, staking token, reward tokens, managers, and rates
   * Fund the contract with reward tokens
   * Call `startFarm()` to begin operations
2. **Reward Configuration**

   ```solidity
   struct RewardConfig {
       address token;
       address manager;
       uint256 rate;
   }
   ```

   * Multiple reward tokens can be configured
   * Each token has its own manager and rate
   * Additional reward tokens can be added post-deployment
3. **Staking Mechanism**

   ```solidity
   struct LockedStake {
       bytes32 kek_id;
       uint256 start_timestamp;
       uint256 liquidity;
       uint256 ending_timestamp;
       uint256 lock_multiplier;
   }
   ```

   * Users lock tokens for a specified duration
   * Lock duration affects reward multiplier
   * Multiplier ranges from 1x to 3x (configurable)

**Integration Steps**

1. **Contract Setup**

   ```javascript
   const farm = await KodiakFarm.deploy();
   await farm.initialize(
       owner,
       stakingToken,
       rewardTokens,
       rewardManagers,
       rewardRates
   );
   ```
2. **Token Approvals**

   ```javascript
   // Approve staking token
   await stakingToken.approve(farmAddress, amount);
   // Approve reward tokens (for managers)
   await rewardToken.approve(farmAddress, rewardAmount);
   ```
3. **Staking Integration**

   ```javascript
   // Lock tokens
   await farm.stakeLocked(amount, lockDuration);

   // Withdraw tokens
   await farm.withdrawLocked(kekId);

   // Claim rewards
   await farm.getReward();
   ```
4. **Event Handling**

   ```javascript
   farm.on('StakeLocked', (user, amount, secs, kekId) => {
       // Handle stake locked event
   });

   farm.on('RewardPaid', (user, reward, tokenAddress) => {
       // Handle reward payment
   });
   ```

#### Best Practices

1. **Security Considerations**
   * Always verify reward token balances before setting rates
   * Implement frontend checks for lock duration limits
   * Monitor total staked amounts against cap
   * Handle emergency scenarios through proper channels
2. **Gas Optimization**
   * Batch withdrawals using `withdrawLockedMultiple`
   * Use `withdrawLockedAll` for mass withdrawals
   * Consider gas costs when setting reward periods
3. **Error Handling**
   * Implement proper error handling for failed transactions
   * Monitor for paused states (staking, withdrawals, rewards)
   * Handle grey-listed address scenarios
