How to Add Custom Networks To MetaMask
The most popular custom networks on MetaMask
- Binance Smart Chain
- HECO (Huobi Eco Chain)
- Polygon (MATIC)
The difference between Mainnet and Testnet?
Mainnet is where tokens have their real value. Testnets are places where developers test their smart contracts. Testnet tokens do not have value.
Notice that Bitcoin, Dogecoin and Cardano are NOT compatible with Etheruem, so they can’t be added to MetaMask and they require their individual wallet.
Before using a custom network with MetaMask, it is essential to understand the hazards of adding and interacting with custom networks. MetaMask does not verify custom networks. You are also responsible for verifying any custom network that you add to MetaMask.
