Setting up Metamask

Download Metamask and create a wallet

To use Hubble, you will need to have a Metamask Wallet in your browser, you can get the add on and instructions on how to install it on https://metamask.io

If you open metamask, you will notice that the currency displayed is ETH, this is because, by default Metamask is connected to the Ethereum Mainnet. Hubble is not deployed on Ethereum, it is only deployed on Avalanche. You must add this network to your Metamask.

Use chainlist.org to add networks

https://chainlist.org/ makes it very easy to add new networks to your Metamask. Once you’re on Chainlist, search for AVAX. You will then find Avalanche Mainnet.

Alternatively, if you want to test Hubble, but not deploy any real funds, you can connect to the Avalanche Fuji Testnet.


In order to add the network, click on connect your wallet, then confirm the Metamask message that will pop up. Then click on add network and confirm again.

It’s done! Now you should be able to switch the network to Avalanche Fuji Testnet. You can select the network by clicking on the drop down menu:


Funding your Metamask wallet

You are now connected to the Avalanche Mainnet. But in otder to transact you will need to pay fees in AVAX. You can buy AVAX from several places, the most common being big centralized exchanges like Coinbase, Binance or FTX. You will need to buy and withdraw to your metamask public address (it starts with 0x…).

In Testnet

The rules on the testnet are the same as in mainnet; you must pay fees to make transactions. To pay these fees, you need Fuji Avax.

Fuji Avax can be obtained for free on the Avalanche Fuji Testnet faucet.


Once you’ve submitted your request, you’ll shortly receive some Fuji Avax in your wallet. If you receive an error, you can expect it to be resolved within a few hours.
