How the guardians are made, minted and kept.

RYUGAMI is a collection of 666 dragon gods of the sea, drawn by hand and issued on Robinhood Chain. It is a work of illustration first and a token second: every plate is drawn before any contract code is written.

This document records what the collection is, how it is issued, and what a holder is entitled to. It quotes no projections, because the collection is sold on its art and its mechanics rather than on a number.

The Japanese dragon is not the western one. Western dragons hoard and burn; they are the obstacle in the story. Ryūjin, the dragon god of the sea, is a ruler. He lives in a palace of coral at the bottom of the ocean, he holds the tide jewels that command the water, and in the legend he is approached with an offering rather than a sword.

He governs the one thing every coastal village depended on and could not predict. That is the framing the collection takes literally: a holder owns a claim on something that governs a system, rather than a creature in a cave.

Supply is final at 666. The mint is closed and the contract cannot issue another dragon.

Every dragon is drawn from one hand-built base, then differentiated across six trait layers: background, character, eyes, mouth, head, clothes. The base never changes, which is what keeps the collection looking like one collection. Above those layers sit the 1 of 1s, drawn individually and outside the layer system entirely.

House counts and trait odds are published together at reveal, in one drop, so nobody reads them early.

Four phases ran, in order: Team, GTD, FCFS, then Public. Team was allocated and disclosed before the mint opened rather than after, and every GTD place was honoured, because we would rather undersell a phase than oversell one and explain it afterward.

Mint price was 0.0006 ETH, published in full before the first window opened rather than revealed on the day. The collection did not sell out, so the published rule applied: the remainder stayed unminted and the contract closed. Final supply is 666.

Six houses, each carrying a staking weight that multiplies everything a holder earns. Rarity here is not a badge on a listing page; it is the coefficient on your standing.

A Legendary earns ten times what a Common earns and a 1 of 1 earns twenty-five times, for as long as the collection exists. That holds regardless of how the houses are eventually sized.

Stake a dragon and it accrues Ryu Score every day. Score is standing inside the collection: it decides allocation in every drop, position in every queue, and share of everything routed back to holders.

Score is standing, not currency. It lives inside RYUGAMI and travels nowhere else. Keeping it untradeable is what keeps it rewarding the people who hold rather than whoever arrives with the most capital.

The dragon never leaves the holder's wallet. Staking accrues from exactly where it sits, so custody is continuous and the asset stays liquid, transferable and listable throughout.

Every 30 unbroken days held, a dragon's staking weight rises permanently by 0.05x, to a hard ceiling of +1x at 600 days. On transfer, tenure resets to zero for the next owner. Not reduced. Zero.

Rarity is purchasable. Anyone who arrives late with enough money can hold the strongest house by the afternoon. Tenure is the one input money cannot skip, because the only input is time already spent.

The ceiling is deliberate. Uncapped loyalty curves become a race the earliest wallet wins forever, which locks newcomers out by a different route. Capping at 600 days means a holder who arrives next season can fully catch up.

One ordering rule governs everything: holders go first, and the public follows. The head start scales by house and applies to every future RYUGAMI drop, every partner collaboration, every merch run, and every allocation negotiated on behalf of holders.

65% of every future drop is spoken for before it is announced. Allocations are negotiated into partner collections on Robinhood Chain and routed to holders by Ryu Score, and partner allocations are taken into RYUGAMI in return.

Fixed and published before the mint: the six trait layers, the house weights, the tenure curve and its ceiling, the head-start ordering, and the share of every future drop that belongs to holders. Listed on OpenSea at reveal.

Set by the market rather than by us: what a dragon trades for after mint. Ryu Score is standing, a measure of position inside RYUGAMI, and we would rather say that plainly than let it be read as something it is not.

Robinhood Chain is a public network. RYUGAMI mints on it the same way any project can, and we describe it as infrastructure, which is what it is.
