Contracts
Robinhood Chain, chain id 4663. Every Twofold contract below is deployed and in use: the current Registry holds 30 listings and the first-generation Registry 30 more, of which 7 are still active and the hook is resting capital in the Steakhouse USDG vault right now. The "first stack" rows are the 2026-08 deployment: its pools stay listed and withdrawable, and the seven that still hold outside deposits stay active; new deposits go to the current contracts. The external addresses are third-party contracts, canonical today.
