To send, you paste or scan the recipient's address, enter the amount, choose a fee and confirm. Your wallet signs and broadcasts the transaction.
Fees are paid for space, not value
Each block has limited space. Miners pick the transactions that pay the most per unit of space, measured in satoshis per virtual byte, written sat/vB.
A transaction's size depends on its structure, not its amount. Sending 1 bitcoin or 1,000 sats can cost exactly the same fee.
Busy or quiet
When many people want to transact, fees rise; when the network is quiet, a few sats per vbyte is enough. Your wallet usually proposes options: fast, normal, slow. Paying less is fine if you are not in a hurry.
- Check the full address before confirming.
- Check the amount and the fee.
- For a new recipient, send a small test first.
In the MEMPOOL tank, the height of each token is the fee rate it pays; only the highest fit in the next block.
