The Ethereum vault differs slightly in the creation of the wallet itself and how it is used.
When creating the Ethereum vault with Nuri, only one (12 words) seed phrase is generated as opposed to 2 (24 words) seed phrases with the Bitcoin wallet. The recovery flow is also more simple - no need for special recovery tools. Just import the seed phrase into any ETH wallet to recover.
Further, the Nuri Ethereum vault can only be created and operated in our mobile app.
