The phone is designed as part of the chain — a cornerstone of it. All on-chain truth lives on the phone side.

The chain isn't deployed yet. The bigger it gets, the more unwieldy it becomes — 3 million lines of Rust, 312 crates. It's starting to feel like it could collapse under its own weight.

The wallet generates keys directly inside the phone's chip TEE. The private key never leaves the TEE. That genuinely lets you say goodbye to annoying private keys and mnemonics for good.

I put up a preview of the wallet client on GitHub:

It's open source now — 1.5 million lines of code. The consensus and core business logic aren't open sourced yet.

0 stars. The original repo had 200+ stars. GitHub said it triggered an AI risk-control flag and 404'd it. I appealed for 10 days, no resolution, so I just deleted it and rebuilt a new one. I feel like GitHub is outdated now — you can't update at the pace of "old-school programming" anymore. Every update has to be a massive batch, and even then it still gets flagged. Speechless.
