Welcome to KiiChain

KiiChain is a next-generation decentralized yield protocol that aggregates and optimizes DeFi yields across multiple blockchains. This documentation will help you understand how the protocol works, how to integrate with it, and how to participate in governance.

Core Concepts

Understanding how KiiChain works will help you get the most from the protocol. Here are the key building blocks:

Vaults

Vaults are the primary interface for users. When you deposit assets into a vault, you receive vault shares (kTokens) that represent your portion of the vault. As the vault earns yield, the share price increases — meaning your kTokens become worth more over time.

• kUSDC — Share token for the Stable Vault
• kETH — Share token for the ETH Boost Vault
• kLP — Share token for the Blue Chip LP Vault
• kNEUT — Share token for the Delta Neutral Vault

Harvest Cycle

Every 4 hours, a keeper bot triggers the harvest() function on each active strategy. This function claims all pending rewards, sells them for the vault's base asset, and reinvests them. The compounding effect is what drives the high APYs you see.

// Simplified harvest logic
function harvest() external {
  uint256 rewards = strategy.claimRewards();
  uint256 bought = swapForBaseAsset(rewards);
  vault.reinvest(bought);
  emit Harvested(bought, block.timestamp);
}

Architecture

KiiChain is built as a modular system where vaults are separated from strategies, enabling upgradeable yield strategies without touching user funds.

Getting Started

Follow these steps to start earning with KiiChain:

1 Connect your wallet — Visit app.kiichain.icu and click "Connect Wallet". We support MetaMask, WalletConnect, Coinbase Wallet, and Rainbow.

2 Choose a vault — Select from our four vaults based on your risk appetite and desired assets.

3 Deposit — Enter the amount and confirm the transaction. You'll receive kTokens representing your share.

4 Earn passively — Sit back and watch your kToken value increase as the vault harvests and compounds.

Fees

KiiChain uses a simple fee structure:

• Performance Fee: 10% of yield generated (taken at harvest)
• Management Fee: 0% (we don't charge for holding)
• Withdrawal Fee: 0% (withdraw anytime, no penalty)

Performance fees are split: 70% to the protocol treasury, 30% to KII stakers as revenue share.

SDK Integration

Integrate KiiChain yield into your own dApp using our TypeScript SDK:

npm install @kiichain/sdk

import { KiiChain } from '@kiichain/sdk';

const kii = new KiiChain({ chain: 'ethereum' });

// Get vault info
const vault = await kii.getVault('stable');
console.log(vault.apy, vault.tvl);

// Deposit
const tx = await kii.deposit({
  vault: 'stable',
  amount: '1000000', // 1000 USDC (6 decimals)
  token: 'USDC',
  signer: yourSigner,
});
await tx.wait();
