title_body: What encoding is used for Yorois Wallet export?
upvoted_answer: After a lot of trial and error, I figured it out myself.
  TLDR
  The &quot;key&quot; that results from the Yoroi export indeed needs to be encoded with bech32, using the prefix acct_xvk.
  Demonstration/Proof
  To test this, we need multiple things:
  
  The seed phrase of our test wallet (for this demonstration we store it in the file phrase.prv): maximum vacuum toe conduct jazz tray romance crawl fossil wisdom disease crazy mountain bird discover
  The &quot;key&quot; exported by Yoroi (for this demonstration we store it in the file root_yoroi_raw.pub): 95e74df114717de17ebfb24c05f9fd1c8019bb6f1de117eec10a43670a692866b837a4a5f51d62f3dc3d630d075c8e39e5294323ba146c386c48123aeef5438a
  The bech32 tool.
  The cardano-addresses tool.
  
  We can now test, whether we can get the same results using our seed phrase and the exported key:
  ./cardano-address key from-recovery-phrase Shelley &lt; phrase.prv &gt; root.xsk
  cat root.xsk | ./cardano-address key child 1852H/1815H/0H | ./cardano-address key public --with-chain-code &gt; root.xvk
  
  ./bech32 acct_xvk &lt; root_yoroi_raw.pub &gt; root_yoroi.pub
  
  cat root.xvk
  cat root_yoroi.pub
  
  This gives the following result:
  acct_xvk1jhn5mug5w977zl4lkfxqt70arjqpnwm0rhs30mkppfpkwznf9pntsday5h636chnms7kxrg8tj8rneffgv3m59rv8pkysy36am658zsh2qnm6
  acct_xvk1jhn5mug5w977zl4lkfxqt70arjqpnwm0rhs30mkppfpkwznf9pntsday5h636chnms7kxrg8tj8rneffgv3m59rv8pkysy36am658zsh2qnm6
  
  This means, that the key exported by Yoroi, when being bech32 encoded with the prefix acct_xvk matches the extended public root key that can be derived from the seed phrase.
