Neither trezor web wallet nor any decred wallet has been released to the general public yet. We can also provide a recovery path for any outstanding trezor users that might have already used the recently released firmware 1.6.2 with mainnet decred coins.\r\n\r\nWe'll need to have this fix applied then wait for the next round of firmware updates to be released before releasing official decred wallets with trezor support.\r\n\r\n[1] https://github.com/decred/dcrd/blob/master/hdkeychain/extendedkey.go#L97\r\n[2] https://github.com/decred/dcrd/blob/master/hdkeychain/extendedkey.go#L464"},"comment":{"url":"https://api.github.com/repos/trezor/trezor-crypto/issues/comments/408889758","html_url":"https://github.com/trezor/trezor-crypto/pull/167#issuecomment-408889758","issue_url":"https://api.github.com/repos/trezor/trezor-crypto/issues/167","id":408889758,"node_id":"MDEyOklzc3VlQ29tbWVudDQwODg4OTc1OA==","user":{"login":"prusnak","id":42201,"node_id":"MDQ6VXNlcjQyMjAx","avatar_url":"https://avatars2.githubusercontent.com/u/42201?v=4","gravatar_id":"","url":"https://api.github.com/users/prusnak","html_url":"https://github.com/prusnak","followers_url":"https://api.github.com/users/prusnak/followers","following_url":"https://api.github.com/users/prusnak/following{/other_user}","gists_url":"https://api.github.com/users/prusnak/gists{/gist_id}","starred_url":"https://api.github.com/users/prusnak/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/prusnak/subscriptions","organizations_url":"https://api.github.com/users/prusnak/orgs","repos_url":"https://api.github.com/users/prusnak/repos","events_url":"https://api.github.com/users/prusnak/events{/privacy}","received_events_url":"https://api.github.com/users/prusnak/received_events","type":"User","site_admin":false},"created_at":"2018-07-30T14:47:36Z","updated_at":"2018-07-30T14:47:36Z","author_association":"MEMBER","body":"> so that the key derivation would be the same\r\n\r\nThis would not work, because you use Blake hash in the BIP32 for Decred."}}
