2. Quick Start

2.1 Adding Kortana to MetaMask

Kortana is fully compatible with EIP-155. You can add the Testnet to your MetaMask or any standard Web3 wallet using the following configuration (EIP-3085 wallet_addEthereumChain):

{
  "chainId": "0x11B3F",
  "chainName": "Kortana Testnet",
  "nativeCurrency": { "name": "Dinar", "symbol": "DNR", "decimals": 18 },
  "rpcUrls": ["https://poseidon-rpc.testnet.kortana.xyz/"],
  "blockExplorerUrls": ["https://explorer.testnet.kortana.xyz"]
}

(For Mainnet, use "chainId": "0x232A" / 9002)

2.2 First Transaction

Because Kortana supports standard Ethereum JSON-RPC and secp256k1 ECDSA signatures, any Ethereum library works without modification.

Using ethers.js:

import { ethers } from "ethers";

const provider = new ethers.JsonRpcProvider("https://poseidon-rpc.testnet.kortana.xyz/");
const height = await provider.getBlockNumber();
console.log(`Current Block: ${height}`);

2.3 Deploying Your First Contract (Solidity)

Solidity contracts compile to EVM bytecode and deploy on Kortana exactly as they do on Ethereum (up to the Cancun hard fork revision).

# Using Hardhat or Foundry, simply point your RPC URL to Kortana Testnet
forge create --rpc-url https://poseidon-rpc.testnet.kortana.xyz/ --private-key <YOUR_KEY> src/MyContract.sol:MyContract

2.4 Deploying Your First Contract (Quorlin)

Quorlin is Kortana's native language. Contracts do not require init-code indirection; deployment verifies the module, stores it, and runs the constructor once.

# Compile a Quorlin contract to KVM bytecode
quorlinc Token.ql -o build/

# Deploy using the Kortana CLI
kortana-cli tx deploy --code build/Token.kvm --key your_wallet.key

2.5 Using the Block Explorer

The Kortana Block Explorer provides real-time visibility into blocks, transactions, dual-VM contract interactions, and dPOH ticks.

• Testnet Explorer: explorer.testnet.kortana.xyz
• Mainnet Explorer: explorer.mainnet.kortana.xyz
