What is
Hub Chain?
A blockchain is a shared record of transactions — and a place where apps can run.
Hub Chain is the Craic Hub ecosystem’s experimental, Ethereum-compatible network. You can send test HUB, create tokens and deploy code that runs as a smart contract.
Right now, it’s a single-node developer testnet, not a decentralized production chain. Use it to learn and test, not to hold real funds. The network may reset and test assets may disappear.

HUB is the native coin used to pay network transaction fees — often called gas.
Get test HUB from the faucet to send transactions and deploy contracts. It is for testing only, has no monetary value and is not the same token as $CRAIC.

FROM CURIOUS TO CONNECTED
Get started in three steps.
Pick up test HUB
Copy your public wallet address into the faucet. Test HUB covers your testnet transaction fees.
Open the faucet →Make your first move
Send a transaction, launch a token or deploy a contract. Then find it in the explorer.

A beginning.
Not a finish line.
Our direction of travel — not a guarantee.
Progress depends on testing, resources and review.
Explore & experiment

Work towards mainnet
Evaluate production infrastructure, independent validators, audits and governance before any mainnet decision.
No mainnet date, migration, airdrop or future reward is promised.
A FEW THINGS WORTH KNOWING
Good questions.
Clear answers.
Still curious? Start with the developer docs.
Is Hub Chain Ethereum?
No. It is a separate experimental chain that supports the Ethereum Virtual Machine (EVM). This lets developers use familiar languages, tools and wallet interfaces. It does not inherit Ethereum’s security or validator network.
Is this a mainnet?
No. This is a single-node Anvil developer testnet with one operator, no independent validators and no external audit. It is not production-ready. State may reset and the service may be interrupted.
Does test HUB have value?
No. Test HUB has no monetary value. It is distributed through a faucet for testing transactions and contracts only. Do not buy it or deposit real funds.
Can I launch a token here?
Yes, the testnet launcher is designed for fixed-supply token experiments. You need a compatible wallet and test HUB for gas. A token launch does not create a trading market, exchange listing or liquidity.
What can developers use?
The testnet supports EVM smart contracts, Solidity and tools such as Hardhat, Foundry and MetaMask. The gateway exposes a limited JSON-RPC interface; full archival indexing and some advanced RPC methods are not included.
Is HUB the same as $CRAIC?
No. HUB is this testnet’s native gas coin. $CRAIC is a separate token associated with the Craic Hub ecosystem. No bridge or CRAIC migration is provided by this testnet.
How fast is Hub Chain?
The network pulse above calculates the observed block interval from recent block timestamps returned by the RPC. That is not a throughput benchmark or a finality guarantee. No transactions-per-second claim is made.
