Every number, and what sets it.
These are read off the contracts, not chosen for this page. Where a number decides how much you are paid, the thing that sets it is named too. Where a contract is not deployed yet, that is said instead of guessed.
Five moves, and only one of them is a decision you make twice.
4,096 of them, priced by mint number alone. When the mint is over the only way in is the secondary market.
Six of them, one per ticker. The floor decides whether your seam matches and which company you are paid in, and it can be changed between runs.
A rig digs a shift only if you bought that shift for it, paid up front in $GRIT. Buying nothing is allowed; the rig just sits out.
Whether the tab is open or not. Everything dug in a shift goes into one pool, and the pool is split by how much ore each rig pulled.
A rig on NVDA mines NVDA, and the stock token is what lands in your wallet. You can take ETH instead; the button for it is on every rig.
Four a day, on the clock and never on yours.
A shift settles when it ends. That is when the pool for it is divided and your claim becomes real.
— UTC · settles in —

| Shift | UTC | What it is |
|---|---|---|
| 00 – 06 | midnight to six | the night shift, all of it |
| 06 – 12 | six to noon | a third of it is night |
| 12 – 18 | noon to six | no night at all |
| 18 – 24 | six to midnight | a third of it is night |
None of them is strictly better. Each is better somewhere.
Three traits, rolled from a seed committed before the first mint and published after the last. They are the whole game.
Cycle — when your rig is good
| Cycle | Good when | Then | Otherwise |
|---|---|---|---|
| Nocturne | at night | ×1.30 | ×0.80 |
| Contrarian | the floor is quiet | ×1.25 | ×0.75 |
| Swarm | the floor is busy | ×1.25 | ×0.75 |
| Steady | its stock is calm | ×1.20 | ×0.80 |
Nocturne is the only one on a clock, so it is the only one you can plan perfectly: play the night blocks and let the noon one idle. The other three depend on what everybody else does, which is the point of them.
A Steady rig on a ticker nobody has read yet is paid ×1.00, not ×0.80.
Draw — how hard it eats
| Draw | Ore | Grit | Ore per grit |
|---|---|---|---|
| Greedy | ×1.30 | ×1.45 | 0.90 |
| Thrifty | ×0.85 | ×0.71 | 1.20 |
Greedy digs more and costs more; Thrifty is the efficient one. Which is better is not fixed: it depends on what a shift pays against what grit costs, and both move.
Seam — which floor suits it
| Seam | On a matching floor | On any other |
|---|---|---|
| Dense · Surface · Volatile | ×1.20 | ×0.90 |
Matching is worth a third more than not, so the floor is a real decision and not decoration. It also fights the crowd: everybody chasing the matching floor makes it busy, which is bad for Contrarian rigs standing on it.
| Floor | Company | Seam |
|---|---|---|
| NVDA | NVIDIA Corporation | Volatile |
| TSLA | Tesla, Inc. | Volatile |
| MSFT | Microsoft Corporation | Dense |
| GOOGL | Alphabet Inc. Class A | Dense |
| AAPL | Apple Inc. | Surface |
| AMZN | Amazon.com, Inc. | Surface |
Two floors to a seam, so no seam is stranded and no rig is born on the wrong side of the map. Which name gets which seam is our judgement, not a measurement. We read NVDA and TSLA as the swingers, MSFT and GOOGL as the flat ones, AAPL and AMZN as the crowded ones. You may disagree; what you cannot do is change it after the fact, because the assignment is written into the contract before the mine opens.
Ticker symbols and company names above identify third-party tokenized equities. Bedrock is not affiliated with these companies, or with Robinhood Markets, Inc., and none of them have endorsed this.
The six token contracts
These are not our contracts. They are the stock tokens on Robinhood Chain that a claim pays out in, and they existed before we did. Check any of them before you bind a rig.

Across the whole chain, 24 stock tokens have moved at all, over roughly 313 transfers. Existing is not the same as liquid, and six live contracts do not add up to a market you can sell into. Claiming in stock is a swap against that book, so it will often fail to fill, and the ETH payout is the one actually catching you. Read what can go wrong before you decide whether that matters to you.
The smaller id survives and keeps its character.
Two rigs of the same tier press into one of the next. The other is burned.
Two tier-I rigs dig 2.0 between them and cost 2.0. Merged, they dig 2.6 and cost 2.2: 18% more ore for every token burned, and it compounds each tier. That is the reason to climb, and the cost is that you end up with fewer rigs than you started with.
There is no fee to forge a tier, on chain or anywhere else, and there is no date it unlocks: it works from the first day the floor is open.
| Tier | Ore | Grit | Ore per grit |
|---|---|---|---|
| I | 1 | 1 | 1.00 |
| II | 2.6 | 2.2 | 1.18 |
| III | 6.76 | 4.84 | 1.40 |
| IV | 17.576 | 10.648 | 1.65 |
| V | 45.6976 | 23.4256 | 1.95 |
When a rig can be merged
| Never bought shifts? | It can merge now. |
| Run finished? | Claim it, then it can merge. |
| Still running? | Wait for the last shift you bought to close. |
Only while it is standing still. Buying shifts puts a rig to work immediately, and a working rig cannot be merged, sold or moved until its run is over and claimed. The rig that is burned must also owe nothing, which claiming takes care of. If the page offers you a partner, the ledger will accept it; if it does not, that rig is busy.
It drains slowly and never empties.
The pool is funded by the creator fee on every $GRIT trade. Half of that fee goes to the pool and half to us, split by a contract with no owner and no way to change where the money goes, including by us.
A shift pays out one twenty-eighth of what is left. That is a week of shifts, and it is a rate, not a countdown: the pool falls by 1/28 and the fee tops it back up.
If nobody works a shift at all, nothing is paid and nothing is spent. The money stays in the pool.
A shift’s payout is the same size whether one rig works it or a thousand. So when few rigs are running, each one earns a great deal, and when many are running, each one earns little. Early is worth more than late here, and by a wide margin, not a small one. That is deliberate and it is also the honest warning: the returns you see in the first days are not the returns the game settles at.
You are never charged more than you bonded.
$GRIT is the only thing you spend. You bond it up front for the shifts you buy, and what the work actually costs is burned when you claim; anything left over comes back to you.
| If a shift outruns your bond | You are paid the share your bond covered, pro rata. You do not go into debt. |
| Burned means burned | The supply falls and nothing is moved to a treasury. |
| A bigger rig eats more | Grit scales 2.2× with every tier, so a tier V burns 23× what a tier I does for the same shift. |
Bond what the rig in front of you needs, not what the last one did: the floor works it out from the rig’s own weight and the last shift’s rate, and says so under the box.
One rule, and everything else falls out of it.
The rate is not a fixed number of tokens. It is set each shift so that the grit burned by everybody together is worth about 6.25% of what that shift pays out.
| In one shift | |
|---|---|
| The mine pays out | 100% of that shift’s pool |
| Everyone burns | 6.25% of it, in grit |
| So miners get back | about 16× the grit it burned |
That ratio does not change with how many people are playing. When the mine is busy the same total is split more ways, so each rig burns less and earns less, in step. Your own share of the burn is your rig’s weight against the weight of everything working that shift, which is why a Thrifty rig costs less to run than a Greedy one.
Grit is not the real cost of playing, the rig is. Grit is a toll, and the pool it buys into is funded by trading fees rather than by the miners. The flip side is the thing to actually watch: those returns exist because the pool has money in it, and the pool is only as full as the fee flow keeps it.
How many tokens that works out to on the day depends on the grit price and who else is digging, so no number is printed here that would be stale by the time you read it.
The awkward parts, in the same font as the rest.
- A working rig cannot move
- Not sold, not sent, not moved through a marketplace, until its run is over and it is settled. This is so nobody can sell you a rig that owes grit or is halfway through work you paid nothing for.
- Nobody can freeze the mine
- Shifts are rolled by a keeper, but if the keeper stops, rollStale opens to everybody two hours later. Anyone can push the mine forward. The game does not depend on us being awake.
- The floors are real tokens
- No invented callsigns and nothing to decode. A floor is a stock token that already exists on Robinhood Chain, and its address is printed above so you can read the contract yourself before you bind a rig to it. What we choose is which six, and that choice is in the contract before the mine opens.
- The book is thin
- Across the whole chain, 24 stock tokens have moved at all, over roughly 313 transfers. A token existing is not the same as a token you can sell into. Claiming in stock is a swap against that book, so on a quiet day it will not fill and the ETH payout is the one doing the work. We would rather say that than let you find out on your first claim.
- Royalty
- 4% on secondary sales, declared in the contract under the standard every marketplace reads.
- What is not deployed
- Ours. The token, the mint and the floor have no address because there is nothing to point at yet, and when that changes it changes here first. The six addresses above are not ours: they are third-party stock tokens that already existed, which is exactly why we can print them and cannot print our own.
All of it, said plainly.
Grit is spent before the payout is known. A shift can cost more than it pays.
You set the minimum you will accept; if the pool cannot fill it, the claim reverts and nothing is lost. ETH is always available instead.
No voting, no dividends, and their liquidity is whatever the market gives on the day.
None of it is a promise of return, and none of the contracts described here are deployed yet.
