A wallet is a way to use keys
A wallet helps you manage the cryptographic keys used to access blockchain accounts. It does not store coins like a physical purse; activity and balances are recorded by a network.

These are general concepts used across blockchain systems. They explain the wider landscape, not FEM-specific network configuration.
Networks keep shared records
A blockchain is a shared record maintained by a network of computers. Applications can use a network to coordinate activity without relying on one central record keeper.
Transactions need careful review
A transaction can make a lasting change. Check the recipient, amount, network, and any requested permissions before approving anything in a real wallet.
Apps connect through wallets
Some onchain applications request a wallet connection so they can propose actions for you to review. A connection is not the same as approving a transaction.
