$DIG on Uniswap v4, Robinhood Chain (4663)

Dig down.
The toll goes with you.

1Every trade pays a toll, and the toll burns at once. Everything burned is depth.
2The ground is laid out in layers. Break through one and the toll steps down for everybody, for good.
3It never steps back up, it stops at a published floor, and nobody is paid for being the trade that breaks through.

The app reads Robinhood Chain live: the block, the gas, your balance. It quotes a trade on the published rule before it is sent and tells you which layer it would break. There is no contract yet, and the app says so.

the surface is up, the floor is down

The layers

Six boundaries, each layer wider than the one above it, and a floor. These are this shaft's own numbers, chosen to make the rule legible in a minute; the real ones are set at deploy and published in the law. The layer the market is in is marked.

Layer	From depth	To depth	Toll in this layer
Layer 0	0	40	12 %
Layer 1	40	100	10.5 %
Layer 2	100	180	9 %
Layer 3	180	280	7.5 %
Layer 4	280	400	6 %
Layer 5	400	540	4.5 %
The floor	540	no end	3 %, and it stays there

Early trades pay the highest toll and do the deepest digging; late ones trade cheaply on a pool the early ones paid for. Nothing is transferred between them, so there is no scheme in it, only an order of arrival, stated here.

The law

Six things written in the contracts at deployment. No function changes any of them, for anyone.

The toll never rises.
The depth never falls, and the layer counter never falls.
The toll leaves as burned $DIG and in no other form, in the same transaction it is taken.
No address has any right over the toll, the depth or the boundaries: no owner, no setter, no pause.
The toll is the same for every address at any given depth.
The boundaries, the step and the floor are fixed at deployment.

Every number is fixed at deployment and published in the law. The team keeps nothing.

Said in plain words

The burn rate declines by construction. A deeper pool burns less per unit of volume. That is the design, said in those words, because a project that hides its own decay is a project that will be accused of hiding it.

The floor is the end of the game. At the floor there is no edge left to reach, and the token becomes an ordinary pool with the cheapest toll it will ever have. The shaft stays, the total burned keeps climbing, and the page says the game is over in those words.

Somebody can dig to the floor quickly. A well funded actor can push volume until the toll bottoms out. It costs them the tolls of every layer on the way, all of which burn, and it leaves everybody else the cheapest possible toll. There is nothing to extract; the destination is reached early, that is all.

Nothing here promises a price. Burning supply on its own sets no price. What the shaft claims is only that the toll is where the depth says it is, and that the depth only ever grows.

Dig it yourself.

The app is the same ground, read from the chain. Quote a trade, see the toll it pays, the depth it adds and the layer it breaks, before anything is sent.
