Hello,
I'm looking for a tool that freezes bitcoins, I've found somewhere but forgot the name of that tool and website.
Moreover, you can set-up the time and date when it will be unlocked.
Thanks!
You may be thinking of Coinb.in. They have
a time locked address tool. I haven't inspected the code myself but it's open source and
can be reviewed on Github. If you decide to use it, I would download and run it offline in a secure environment rather than using the web-based version.
