Flit is a bird about to leave one perch for another; this is that, photographed. Chosen by LOOKING at a contact sheet of 48 Creative Commons swallow photographs, not by optimising a statistic.

The file this site serves is that photograph scaled, softened and re-encoded by tools/make-ground.mjs; the original is never served. The brightness and saturation were chosen by measuring the painted page against the reference, and the numbers are in CLAUDE.md.

Newsreader (Production Type for Google Fonts, SIL Open Font License) for the display type, Inter Tight (Rasmus Andersson, SIL OFL) for everything else, and IBM Plex Mono (IBM, SIL OFL) for addresses and calldata.

Flit deploys nothing. Every transaction it builds is a call to contracts that were already live on Robinhood Chain:

Morpho Blue and Bundler3 are Morpho Labs'; the tokenized stocks and the chain are Robinhood's; USDG is Paxos'. None of them has anything to do with Flit, and none of them has endorsed it.

ethers.js (MIT) in the browser for encoding and signatures — vendored, not loaded from anyone's CDN. Hardhat (MIT) forks the chain for the transaction suite, solc compiles the properties, and headless Chrome measures the page and renders the brand files. Those three live outside this repository, so nothing ships with the site but the page itself.

Every figure on this site is computed into data/figures.json and filled in by tools/build.mjs, which fails the build rather than printing a number nobody computed. The directory of tokens and markets is read from the chain by tools/scan.mjs; what a move costs comes from transactions the fork suite actually sent; and who could move today comes from running the planner over every position on the chain.

Last scan: block 64,002,613. Flit is not audited.
