The Crypto & Web3 Glossary — cover

A free look inside

This is the plain-English standard.

Six real entries from the glossary — exactly as they appear, no rewriting for the sales page. If these read clearly, the other 139 will too.

Wallet

Wallets & Keys

Software or hardware that lets you view your crypto holdings and authorize transactions. The wallet stores your keys, not the coins themselves — the coins live on the blockchain.

Seed Phrase

Wallets & Keys

A list of 12 or 24 words that can recreate a wallet and all its keys. It is the master backup and is never entered into websites or shared with anyone.

Finality

Transactions & Fees

The point at which a transaction is considered permanent and will not be reversed. Different networks reach finality differently.

Gas

Transactions & Fees

The fee paid to have a network process a transaction. The amount changes with how busy the network is.

Stablecoin

Assets & Tokens

A token designed to hold a steady value, often tied to a currency such as the US dollar.

Chargeback

Payments & Business Use

A reversal of a payment by a bank or card network. Standard blockchain payments do not have an equivalent automatic reversal.
