[WTB] Teach me to manually create an OP_RETURN tx

[mcliu]

So instead of entering a receiving address and an amount one would enter '{"data":40_bytes}' ?

Yes, basically it comes down to this.

Here is an example:

1. First, I list unspent outputs of the address I'm going to use.

Code:

bitcoin-cli listunspent 0 999999 '["1BxtgEa8UcrMzVZaW32zVyJh4Sg4KGFzxA"]'

..........


5. Here is the result:

I have a problem trying to decode the data back
Is there any way I can see the data I added while creating raw transaction without using this website?  --> https://live.blockcypher.com/btc/tx/b394e47f8141f725f25854d57e91fb67d91782dbe581b2f449990ba25a116d2d/

In Bitcoin Core, you can use:

Code:

bitcoin-cli getrawtransaction <txid> 1

However, the data then isn't shown isolated, but embedded in an output script. And since it's hex, you may also need to decode it.


By the way, thanks a lot for the one sending 0.0518131 BTC to my tip address posted in this thread!
