Write your own message into Bitcoin
Everything else on this site is a message someone already wrote. This page lets you add one. Your own wallet signs and broadcasts it — this site never touches your keys or your coins. It only assembles the transaction for you to approve.
This cannot be undone. Once a block includes your message it is
copied to tens of thousands of computers, worldwide, permanently. There is no
edit and no delete — not by you, not by us, not by anyone. Do not write anything
you would not want attached to your address forever.
What it costs
Two separate amounts, both shown before you sign:
- The miner fee — paid to whoever mines your block, not to us. It depends on the size of your message and how busy the network is.
- 5,000 sats to this site — for building the transaction and keeping the archive running.
Your message output itself carries zero bitcoin: OP_RETURN is provably unspendable, so nothing is "sent" to it. The rest of your coins return to you as change.
