A digital asset on a network
Cryptocurrency exists as records on a blockchain network. A wallet helps you view those records and authorize changes, such as sending an asset to another address.
Different networks have different native assets and rules. Ether (ETH) is used on Ethereum, SOL is used on Solana, and tokens such as USDT can exist on supported blockchain networks.
What is a blockchain?
A blockchain is a shared record of transactions. Many independent computers follow the network’s rules, check new transactions and keep compatible copies of that record. This lets people transfer digital assets without every transaction being recorded in one company’s private database.
Direct transfers
When you send crypto, you enter a destination address, select an asset and amount, and approve the transaction with your wallet. The network then processes it. The receiving address can belong to another person, an exchange, a service or another wallet you control.
Fees, volatility and risk
Most blockchain transactions require a network fee. Fees can change with network demand, and a transaction may take longer during busy periods.
Crypto prices can change quickly. Tokens can lose value, networks and smart contracts can fail, and scams or incorrect transfers can lead to loss. Crypto is not risk-free, and this guide is educational rather than investment advice.
