MUTATIONS: what changes, what never does
Every RIGS token renders its art on chain as an animated SVG. The art is swappable by the owner (we just upgraded it for all 10,000); the traits are minted into the collection contract and can never move. Same token, same rarity, new artwork, forever.

Every value comes from our own photographed finds and the harvested mineral archive, not from an image generator. We only print a reading we actually have.
Every piece below was hand-dug by the dev on real mining missions, then photographed and weighed. Each one becomes an onchain certificate that carries its own photograph, weight, UV fluorescence and USD value, so the photo you see here is the same photo the certificate shows on OpenSea and in your wallet. We are prospectors, not gemologists: labels are our best read, and every data point stays updatable onchain with a visible correction history.
- Dig & photograph: hand-dug on a real mission, shot in natural and UV light.
- Weigh & read: grams on a scale, UV coverage %, radiation left unclaimed until actually measured.
- Mint: an onchain certificate is minted to the treasury for that exact piece, with its photo baked in.
- Own or trade: the certificate is the digital title. Trade it on OpenSea, or redeem it for the physical rock (US shipping).
- Re-verify: corrections to weight, composition or UV are written onchain with full history; the certificate never silently changes.
Purchases from the contract split 70% USDG / 30% GMTS with a 15% RIG-holder discount. Catalog prices are honest ranges; the certificate carries the exact USD figure locked at mint. Physical redemption is US-only.
STORE: CERTIFICATE PIPELINE
The certificate contract is live on Robinhood Chain (owner = treasury Ledger) and every catalog piece is minted in batches as measurement completes. Nothing is sold before it is minted.
Treasury sales are paused. The vault is display-only for now. Certificates you already own are normal ERC-721s: trade them peer-to-peer or on OpenSea.

Safety & disclosure
Experimental. Prospector-labeled, not gemologist-certified. Never investment advice. UV-fluorescent pieces ship with safe-handling guidance and a USPS Pub 52 / DOT 49 CFR §173.421 disclosure (Excepted Package UN2910, surface <0.5 mrem/hr). Radiation is left labelled “not yet measured” onchain until we actually have a reading. We never publish a number we have not taken. Physical redemption is US-only; certificates themselves are tradeable anywhere.
