What are all of the actions that may be carried out with a seed phrase

Anybody with the data of a seed phrase has full management over the funds saved with that seed phrase. It’s not protected to make use of, and any transactions made with it up to now might be linked collectively as belonging to 1 pockets, that is all. I’m not positive why somebody malicious (as you name them) would ship funds to a seed phrase they know is just not underneath their full management, since you may simply sweep them to your self.

For example, I went to https://iancoleman.io/bip39/ and generated this seed phrase:

cloth good tissue personal topic lower loopy repeat unlawful pulp depart reward

Since I’ve shared it right here it’s now insecure and sending any funds to an handle related to it (e.g. bc1qq6hkw49wexxsd4n3avfwjkc06fejdwlxgxzqcq) means another person will ultimately take them. However so long as I do not use this seed phrase sooner or later, I’ve not compromised my safety in any means.
