RPC Endpoints

List of RPC endpoint URLs

These are public RPC URLs available on each network.
It's important to note that public RPC URLs generally have rate limits, so they may not be reliable 100% of the time.
For the Hop Node, it is highly recommmend to use custom RPC endpoints from an RPC provider service such as Infura or Alchemy.
Check out https://chainlist.org/ as an easy way to connect wallet and add network to your wallet.
Note: the Infura project ID in the examples below is the default that ethersjs uses.
