01 / THE APPROACH
SECURITY THAT CAN EVOLVEKeep control.
Through every change.
Owning an asset means controlling what happens next. That control should survive a change in the mathematics behind it.
Today, Aftercurve Vault brings encrypted local storage and verified post-quantum device transfer to your browser. Our Ethereum research explores hash-based account authorization, deliberate recovery, and inspectable migration.

04 / FIRST PRINCIPLES
THE DETAILS ARE THE DIFFERENCETrust is in
the architecture.
The work is in the authorization paths, the recovery rules, and the assumptions that remain.
Read the security boundaries ↗Every path matters.
Transfers, recovery, and upgrades belong in the same threat model. Protection is only as strong as the permissions around it.
Verification before migration.
Prove destination control. Rehearse recovery. Review supported assets. Start with a small transfer.

ETHEREUM RESEARCH ↗A FEW IMPORTANT QUESTIONS
Clarity,
from the start.
What does Aftercurve protect?+
Vault encrypts stored passwords, API keys, private notes, and recovery codes, and provides verified offline device transfer. The separate Ethereum research track explores dedicated smart-account authorization. Their security scopes are distinct.
Is the protocol live on mainnet?+
No. Vault is downloadable browser software and needs no blockchain transaction or contract deployment. The Ethereum account protocol remains in research; the studio is a local planning tool. Neither deploys accounts, signs transactions, or accepts deposits.
Does this make Ethereum quantum resistant?+
No. Account authorization is one layer. Ethereum consensus, data commitments, application contracts, and asset issuers have their own dependencies. Aftercurve's scope must remain explicit.
Can I use my existing wallet?+
You can plan for an existing address in the studio. Actual protection would require moving supported assets or control to a dedicated account with verified authorization rules. Merely connecting a wallet would not change its security.
