Tornado, Samourai, and a Warning:

In a surprising and concerning shift, the DOJ has targeted non-custodial crypto wallet developers for unlicensed money transmission, which starkly deviates from longstanding U.S. policy.

This abrupt move, seen in recent charges against…

Gas fees coming to twitter.

I just hope the blockspace is cheap.

One of the challenges with 3074 is the fact that the commit is obscure for the wallets. What if we all agree (like in an ERC) that this commit must be formated as an ERC-712 typehash?

Wallets know how to display these. Contracts known how to produce them.

One day remaining to vote. Quorum has NOT been reached.
