We offer a split-key feature which guarantees by math security. No trust is needed, this is why we use cryptocurrency.
we've discussed this in your other thread, split key should NOT be optional
and your split key feature doesn't work for me, it keeps giving me error
Invalid prefix, double check that your characters are allowed, redirecting you shortly...
can someone else confirms this, or it was just an error on my side
edit: to answer OP question
I tried with both compressed and uncompressed public key bitcoin address for prefix "test"
