RPC Endpoint

An RPC endpoint is the network address a wallet or app calls to read blockchain data and broadcast transactions. RPC stands for remote procedure call: your wallet asks a node, through this endpoint, for your balance, the current gas price or the status of a transaction, and pushes signed transactions out to the network. Most people use public or commercial endpoints rather than running their own node, which is convenient but means the provider sees your IP address and the addresses you query, and could in principle return stale or filtered data. Adding an unknown custom RPC to a wallet is a common phishing tactic, so only add endpoints from sources you trust.
