Ethereum Foundation to Launch Signing App for Passport Prime

The signal here is institutional posture rather than product: the Ethereum Foundation directly co-developing a signing app marks a shift from protocol stewardship toward shaping how users custody and authorize transactions on its network. Pairing that with a Ledger co-founder's involvement suggests the EF is borrowing established hardware-security expertise rather than building it in-house. For hardware wallet makers and self-custody users, this hints at a more EF-aligned signing standard taking shape. With no public release yet, whether the app ships broadly or remains a reference design is the open question.
