Quick answer
What should I verify before copying blockchain network settings?
Match the term to the exact field you are configuring: chain ID with chain ID, RPC URL with RPC URL, gas token with gas token, and block explorer with explorer hostname. Then open the status page and source documentation before using the values in a wallet, script, or app.

Definition
RPC endpoint
An RPC endpoint is a node URL that wallets and apps use to read from or submit transactions to a blockchain network.
Definition
Public RPC
A public RPC is a shared blockchain node endpoint offered for convenience, usually with rate limits and no production reliability guarantee.
Definition
Node provider
A node provider runs blockchain infrastructure and exposes RPC endpoints, often with paid plans, service limits, regions, and monitoring features.
Definition
Gas token
A gas token is the asset used to pay transaction fees on a blockchain network.

Block explorer
A block explorer is a public interface for looking up blockchain blocks, transactions, addresses, contracts, and tokens.
Definition
Sequencer
A sequencer is infrastructure that orders transactions for many rollup-based L2 networks before they are finalized or posted elsewhere.
Definition
Rollup
A rollup is a scaling network that executes transactions off an underlying chain while posting data, proofs, or settlement information back to it.
