How the Chain Details Are Checked

The chain details are checked against each chain's own documentation and a second source, the public chain registry at chainid.network. Every public RPC on a page answered a test call on the date shown. Wallet buttons ask your wallet to add the network; your wallet shows the details and asks you to approve.
