quick question about hodlers who have taddress on trezor hard wallet .
will the new unified address affect anything in that wallet ? or should they do anything before activation ?
Existing transparent addresses will continue to work after NU5, and are not affected by UAs. Where UAs will become relevant to Trezor users is when shielded Zcash support lands in Trezor, at which point it will likely provide the ability to generate an Orchard + transparent UA (it will necessarily produce UAs anyway because Orchard addresses are encoded as UAs).
Congratulations, ECC team, for this milestone, and kudos for the innovation, vision, and years of hard work that brought it to fruition!
Iβm impressed by how you built such a complex cryptographic system to the highest standards of specification, implementation and auditing; and Iβm giddy about the possibilities it opens for new capabilities in Zcash and its ecosystem.
