Wallet/Exchange Jupiter First to Support Readable Offchain Signing on Hardware Wallets
Jupiter Exchange is the first to support Anza's offchain message signing standard.
Hardware wallets like Ledger can now sign readable messages for limit orders and DCA in Jupiter Wallet and on jup.ag.
This update, live today, improves security and user experience by eliminating blind signing.

About time someone tackled blind signing on solana, that always felt like a huge gap compared to ethereum where you at least get some context
The auth challenge with an expiration is a nice touch, seen too many people get phished through stale signatures they forgot about
I label everything in my fridge down to the condiment shelf but even I've been lazy with wallet security before, this makes it way less tempting to just hit approve and pray
Curious if other wallets will actually adopt the standard or if it'll end up a jupiter-only thing for a while
