Crypto payment basics

The parts of a cryptocurrency payment

Every cryptocurrency payment has a currency, a network, a destination, an amount, and a fee. You usually need to check these details yourself before sending.

Read the topics in order or open the one that matches the task in front of you.

The four details behind every payment

1. Currency: the asset being sent, such as BTC, ETH, or USDT.
2. Network: the system carrying the transfer, such as Bitcoin, Ethereum, or Tron.
3. Destination: the recipient's wallet address and, when requested, a tag or memo.
4. Control: the person or company able to approve transfers from a wallet.

The currency and network are separate choices. Sender and recipient must use the same network for the transfer.

Start small while you learn

When you use a new wallet, provider, network, or destination for the first time, begin with a small amount you can afford to lose. About 5 USD or 5 EUR worth of cryptocurrency can be a useful test when provider minimums and network fees make that practical.

Confirm the test reaches the intended wallet before moving more. Check the larger transfer again from the beginning because a successful test does not prove that a later address, network, or amount is correct.

What these details help you check

Use these details to read a payment request, identify the exact currency and network, understand where fees appear, and determine who controls the wallet. Stop and ask the recipient when an instruction is missing or does not match.

You do not need to memorize address formats or network rules. A good wallet shows the network and reviews the important details before you approve a transfer. Your job is to slow down, compare those details with the recipient's request, and never guess.

A sensible reading order

Start with currencies and assets and networks and chains. Then learn how wallet addresses identify a destination and how custody and control affect who can move funds. When you know the payment route, compare wallet apps and hardware wallets that support it.

When those ideas feel clear, follow a payment from purchase to confirmation and see who may be involved before choosing a purchase guide.
