Sending and Receiving: The Basics of a Transfer
What You'll Learn
- The minimum information every crypto transfer needs
- Why receiving is simpler than sending
- What actually happens once you submit a send
The Big Idea
Let me simplify this for you: every crypto transfer, at its core, needs just two things — a destination address and an amount. But getting a transfer right in practice means being deliberate about exactly where, and on what network, that address actually lives. I will explain exactly what that means.
Let's Break It Down
Receiving crypto is the simpler side. You share your address, which you learned about in Crypto Foundations, with whoever is sending to you, and the funds arrive once their transaction is confirmed. You do not need to do anything active to "accept" it — the network handles that automatically, once the transaction is valid.
Sending puts more of the responsibility on you. You need the recipient's correct address, and — as the next lesson covers in depth — you need to make sure you are sending on the correct network for that address.
Once you submit a send, it becomes a transaction that gets broadcast to the network, picked up by miners, and included in a block, exactly as I described in the blocks-and-mining lessons back in Crypto Foundations. From that point, the transfer follows the same lifecycle you already learned: it starts with zero confirmations, then gains confirmations as more blocks are added on top of it, becoming progressively more final.
Real Example
Sending crypto is similar to filling out a wire transfer form at a bank. You need the exact destination details to be correct, because once it is submitted and processed, there is no customer service line you can call to reverse it if the details were wrong. The transaction has already been broadcast to, and accepted by, the network.
Why It Matters
I want you to notice this important asymmetry: receiving is passive, but sending is active and requires precision. That sets the stage for the rest of this module, which focuses specifically on the details that make a send go right — starting with the single most important one: matching the network.
Common Mistake
Please do not assume a transaction can be cancelled or reversed after it is submitted, the way a bank transfer can sometimes be disputed. Once a crypto transaction is broadcast and confirmed by the network, it is final. There is no central authority able to undo it.
Quick Check
What is required, at minimum, to send a crypto transfer?
Key Takeaways
- Receiving crypto just requires sharing your address — the network handles the rest once a transaction is valid.
- Sending requires the recipient's correct address and puts more responsibility on you to get the details right.
- Once submitted, a transaction follows the confirmation lifecycle from Crypto Foundations and cannot be reversed.
