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

   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

   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

   const farm = await KodiakFarm.deploy();
   await farm.initialize(
       owner,
       stakingToken,
       rewardTokens,
       rewardManagers,
       rewardRates
   );

2. Token Approvals

   // Approve staking token
   await stakingToken.approve(farmAddress, amount);
   // Approve reward tokens (for managers)
   await rewardToken.approve(farmAddress, rewardAmount);

3. Staking Integration

   // Lock tokens
   await farm.stakeLocked(amount, lockDuration);
   
   // Withdraw tokens
   await farm.withdrawLocked(kekId);
   
   // Claim rewards
   await farm.getReward();

4. Event Handling

   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
