The piece

Every piece mints with the same sealed image: twelve glowing lines, purple fading to gold, flat. After a valid reveal transaction, five on-chain groups shape the visored head: character, headwear, glass, frame and background. The contract derives each piece's seed from the revealed collection seed plus its pool, buyer, id and amount. A producer may calculate these traits early if they know the seed. No live holder preview exists.

Anatomy of a piece, opened

The numbered badges below label the four parts, drawn on the real tile in its opened state: no outlines anywhere, the only ink in the picture is the pair of eyes. Sealed, every piece looks identical to this one, minus all four of these parts; nothing below is visible, or decided, until the round. The example combination shown here (square silhouette, crown gradient family, soft seal tint, satin frame finish) is chosen only to make every part visible at once; it is not a rarity claim.

1 2 3 4

1 Frame finish. The casing around the sealed glass, in one of three finishes: gloss, satin or frost.
2 Seal tint. The tinted pane inside the frame, two flat bands per tint, moving along the same purple-to-gold family as the twelve lines, in one of four tints from the locked palette.
3 Revealed silhouette. The shape the piece's own lines bend into once opened, clipped by the glass with its own soft under-shade. Four shapes: round, bean, square or star.
4 Gradient family. An accent that sits over the silhouette once revealed, marking which lean of the purple-to-gold gradient this piece carries. Seven options, plus none.

Every option of every trait

Each tile below is drawn by docs/js/docs-tile.js from the real weight table in js/snag-market.js, with the other traits held at their most common pick so the changing part is easy to see. The number under each tile is its weight out of 1000. These are the same five groups the contract itself reads: character, headwear, glass, frame and background.

Revealed silhouette (character)

Gradient family (headwear)

Seal tint (glass)

Frame finish (frame)

Backdrop (background)

Same swap, same piece: a worked example

This is not a real buy. It uses one illustrative, clearly placeholder field set to show the exact arithmetic js/snag-market.js runs, computed by docs/build-docs.mjs and written to docs/js/docs-data.js, never typed by hand on this page. This preview arithmetic shows the shape of the calculation the contract runs after the round; it does not include the round's own revealed seed, since no round has happened yet, so treat the traits below as an illustration of the five-way split, not a preview of what any real buy will open into.

The illustrative preview hashes these four fields. The actual on-chain piece also mixes in the revealed collection seed, so this value cannot predict a live piece:

Reading the illustrative seed across five 16-bit picks modulo 1000, in the order character, headwear, glass, frame, background, gives this example:

character, headwear, glass, frame, background.

This exact mix: 1 in

Demo values in $CACHET. Try 250K, 1M, 5M or 15M. The demo minimum is 500K; the 250K buy gets no piece. These amounts are illustrative, not the collection minimum.

Change an input and the derived seed can change. The sealed on-chain image hides the five trait names until a valid reveal transaction lands. Public owner and transaction data remain visible throughout.
