If NuFi wallet were to disappear, a user could restore their accounts into another non-custodial wallet using the recovery phrase that they write down during wallet setup; this backs up all accounts and assets. Hardware wallets users could restore their accounts in another non-custodial wallet by re-pairing their device.

• Our CI pipeline includes automated detection of vulnerabilities in the libraries we use, so that we update them ASAP

[konopkja]

[goldieben]

not supported: ZK sync, Taiko, starknet, scroll, mode. Correct @goldieben

Thank you for the feedback @konopkja! Support for the chains zkSync, Taiko, Scroll and Mode can be added to NuFi manually, e.g. using Chainlist or entering the chain's information manually (please see image attached below: those chains are the ones enabled at the top of the list of blockchains) but not Starknet, it seems, this was an oversight on my part and I'm sorry about that one. I'll adjust the text now. Thanks again!

For reference:

[konopkja]

no worries, for metadata L2 support we do not consider custom manual chain adding, but good to know! Otherwise lgtm.

Are you able to make PR with adding the wallet yourself?

[goldieben]

@konopkja Understood, and thanks for letting me know. I won't be able to make a PR personally but someone from our team will do that, so I'll hand over to them.

Thanks again ever so much for your help.
