The chain ID is doing three jobs at once: it is the EIP-155 replay-protection domain, the key under which the network is named, and the suffix of the AuxPoW commitment tag. A gateway that commits krnx-42069 into a parent-chain coinbase is mining for testnet, and a mainnet node will not accept that work.

​
Endpoints

There is no hosted public endpoint yet. Run your own node — see Run a node — and point the examples in these docs at it.

​
Parameters that differ

The testnet trades production safety margins for turnaround time. A five-minute lockup exists so a full reward lifecycle — mine, lock, unlock — fits inside one test session. Do not build anything that assumes it.

​
Execution layer

Kronex keeps the Ethereum JSON-RPC surface: eth_, net_, web3_ and txpool_ behave as they do on any go-ethereum node, so existing tooling (ethers, viem, web3.js, Hardhat, Foundry) works once you set the chain ID and endpoint. Everything Kronex adds lives under the krnx_ namespace.
