The importance of testing your collections
Before you deploy a collection on Highlight, you should always first deploy it to a testnet. Remember, deploying a collection to a blockchain is a permanent, irreversible process. Deploying to a testnet helps to make sure your collection appears as you intend it, and lets you correct any mistakes before they become permanent!
What is a testnet?
Testnets are dedicated testing blockchains that imitate the behavior of a real blockchain. Highlight supports several testnets, allowing you to launch your collection for free and preview how it will behave, before you decide to launch it to a production blockchain.
Deploying to testnet
To deploy your collection on a testnet, simply follow one of the ordinary creation flows and select "Testnet" as your blockchain, and then either Ethereum Sepolia or Base Sepolia. All collections, regardless of the final chain you deploy to, can be tested on either test network.
Getting testnet ETH
To actually use a testnet, you'll need to use testnet ETH. You can get a small amount of testnet ETH for free from one of several faucets:
What to check for
When reviewing your testnet collection, you'll want to make sure it appears exactly as you'd want it when you launch it live. Below are a couple of best practices when testing:
Make sure your artwork, text descriptions, and traits show up as expected.
Mint several test tokens (the more, the better). Make sure the tokens appear as you'd expect. Be sure to take a look at the various Highlight pages, and also look at it on marketplaces like OpenSea.
If you encounter difficulties or are unsure why something isn't working, send us an email at gm@highlight.xyz.
Adding a testnet to your wallet
Depending on your wallet software (e.g., Metamask, Coinbase Wallet) and the specific testnet you want to connect to, you may not always find the desired testnet available to add. In such cases, you will have to manually enter the relevant information.
In Metamask, you can choose "Add a network manually" and input the testnet information, including the network name, RPC URL, Chain ID, and currency symbol. Among these, the RPC URL and the Chain ID are the most critical pieces of information that you must ensure are accurate.
