Why is there a small difference between addresses derived by the cardano-address tool and Yoroi?

Question

Let's consider a Yoroi test wallet with the following seed phrase: maximum vacuum toe conduct jazz tray romance crawl fossil wisdom disease crazy mountain bird discover

The first address generated by Yoroi is then: addr1q96a42g6ajjhu5gfw8gch2w0vflfxkqw53pxyufgacscal5f0vdmnq834g9upwe2g0cfzwemmwvfnyawg89g8xeqx4kstanhan

However, if I derive the first address using the cardano-addresses tool like this (where phrase.prv holds the seed phrase):

./cardano-address key from-recovery-phrase Shelley < phrase.prv > root.xsk
cat root.xsk | ./cardano-address key child 1852H/1815H/0H | ./cardano-address key public --with-chain-code > root.xvk
cat root.xvk | ./cardano-address key child 0/0 | ./cardano-address  address payment --network-tag mainnet

I get the following address: addr1v96a42g6ajjhu5gfw8gch2w0vflfxkqw53pxyufgacscals656txx

For direct comparison: addr1q96a42g6ajjhu5gfw8gch2w0vflfxkqw53pxyufgacscal5f0vdmnq834g9upwe2g0cfzwemmwvfnyawg89g8xeqx4kstanhan addr1v96a42g6ajjhu5gfw8gch2w0vflfxkqw53pxyufgacscals656txx

So the first part of the addresses is identical (except for the first letter after the prefix), but there seems to be missing something. What am I doing wrong?

Thanks.

Answer 1

There is indeed missing a part of the address: the delegation part. For more information, please refer to this partially duplicate question and CIP-0019.

To derive Yoroi addresses from a seed phrase using the cardano-addresses tool:

./cardano-address key from-recovery-phrase Shelley < phrase.prv > root.xsk
cat root.xsk | ./cardano-address key child 1852H/1815H/0H | ./cardano-address key public --with-chain-code > root.xvk

# Derive the stake key.
cat root.xvk | ./cardano-address key child 2/0 > stake.xvk

# Only the index of the payment address is incremented to yield the next Yoroi address:

# First address
cat root.xvk | ./cardano-address key child 0/0 | ./cardano-address address payment --network-tag mainnet > payment.addr
./cardano-address address delegation $(cat stake.xvk) < payment.addr > payment-delegated.addr

# Second address
cat root.xvk | ./cardano-address key child 0/1 | ./cardano-address address payment --network-tag mainnet > payment.addr
./cardano-address address delegation $(cat stake.xvk) < payment.addr > payment-delegated.addr

# Third address
cat root.xvk | ./cardano-address key child 0/2 | ./cardano-address address payment --network-tag mainnet > payment.addr
./cardano-address address delegation $(cat stake.xvk) < payment.addr > payment-delegated.addr
