Hi all,
We've been working on a new self-custody wallet called Lock.com and wanted to put the design in front of this crowd before the whitepaper goes out, mostly because we'd rather hear where it falls short now than later.
The thing that's bugged us about most wallets is how much is packed into a single process. The UI, the signing, the RPC calls, chain state, the approval prompts - they're all basically sitting next to each other. So if any one of those gets compromised, your seed is usually in reach. The whole idea with Lock.com is to keep the seed in as small a corner as possible and make the rest of the app talk to it across a boundary instead of sharing the same space.
In practice that means a few separate pieces:
Treasury - the only part that touches seed-derived material and actually signs.
Node - deals with chain state, providers, routing, all the network-facing stuff.
Wallet - the interface you actually click around in.
Vault daemon - handles the device key on its own, on platforms that let us do it.
The point isn't "we made another wallet." It's that a problem in one piece shouldn't hand an attacker the keys.
On the post-quantum side, let me be careful with words because I know how this gets thrown around. We're using hybrid classical + post-quantum schemes inside the wallet's own architecture and its comms layers. That does not make any existing chain quantum-safe-on-chain signatures still come down to whatever cryptography that chain uses, and that's not ours to change.
The whitepaper goes into the threat model and trust boundaries, the treasury/node/wallet separation, the vault daemon and device-key handling, the hybrid crypto choices, seed generation and recovery, importing existing wallet formats, the send / multi-send / swap / bridge flows, what verification before signing looks like, and some of the encrypted chat and decentralised storage ideas. It's not out yet but it's close.
What I'm actually after here:
- People who've built or audited wallets tearing into the architecture and threat
model. - Anyone who thinks the post-quantum framing is wrong or sloppy.
- The self-custody frustrations you still deal with that nothing on the market has
fixed. - Folks who want to follow along until it's public.
More to come, including the whitepaper and early access details. Site's here if you want it:
