1. What is OSR?
Oil Strategic Reserve (OSR) is a gamified, virtual node-mining platform on Robinhood Chain. You burn $OSR tokens to deploy virtual Oil Rigs and Mining Shafts on your own 3D compound. Those nodes produce real rewards over time, paid out from the $OSR emission reserve — bought at launch and deposited in the distributor — released via a Bitcoin-style halving curve.
Think of it like an incremental game where every action is on-chain: your rigs and shafts are real state, your burns send $OSR to the burn address, and your rewards settle to your wallet.
Both Oil Rigs and Mining Shafts accrue $OSR per second. Progression is wallet-wide: you raise your Compound Level to unlock more node slots, more daily crates, and higher rarity pools. Mining Shafts earn bonus node slots at higher levels; Oil Rigs are claim-only in v1.
2. Quick start
- 1
Connect a wallet
Open the Command Center and connect an EVM wallet (MetaMask, Rabby, …). In mock mode you can just paste any address to try the game.
- 2
Deploy your first node
Tap Deploy. Pick an Oil Rig or Mining Shaft, burn the required $OSR + small ETH fee, and it appears on your compound.
- 3
Let it produce
Nodes accrue rewards every second based on your components' grow-power and your share of the global halving emission. Watch pending rewards tick up in your HUD.
- 4
Claim, open crates, compound-upgrade
Claim to cash out (2% fee, 1h cooldown), open Supply Crates to upgrade your components, or compound-upgrade your wallet to unlock more nodes and crates. Repeat.
3. Nodes: Rigs vs Shafts
Node capacity scales with your Compound Level: 2 per family at L1, growing to 8 per family at L10 — and Mining Shafts add bonus slots on top (+2 at L5, +3 at L7, +4 at L9). Each node is an independent entity with its own components and production rate.

4. Levels & Auras
Your nodes' visual level mirrors your wallet's Compound Level (L1 → L10). Each level upgrades the rig's material era — rough steel through reinforced and high-tech to a black-and-gold prestige finish — and grows its size, making progress visible at a glance on the compound.
Production itself comes from your components, not the visual level: your rate = min(your GP / network GP, 30%) × E(t) — where GP (grow-power) is the Formula D multiplier of your installed components.

Higher levels upgrade the rig's material era (rough steel → reinforced → high-tech → black-and-gold prestige), grow its size, and light a powered deck ring at the milestone levels. The per-component rarity glow layers on top.
5. Components & Crates
Each node has 4 component slots. Components are earned by opening Supply Crates — 500 $OSR at L1 scaling to 1,625 $OSR at L10 (split 50/30/20 burn / reserve / treasury), plus a flat ETH protocol fee. Your daily crate limit scales with Compound Level — from 3/day at L1 up to 20/day at L10, per node type. Every drop has a rarity tier that multiplies the node's output:
| Rarity | Multiplier | Visual |
|---|---|---|
| Common | 1× | |
| Uncommon | 1.8× | |
| Rare | 3× | |
| Epic | 10× | |
| Legendary | 50× | |
| Mythic | 300× | |
| Divine | 3,000× |
A node's total multiplier uses Formula D: the average of its 4 slots' durability-adjusted multipliers, raised to the power 0.75 (capped at 500×), then multiplied by a rarity-boost stack (Epic ×1.05, Legendary ×1.15, Mythic ×1.4, Divine ×2.0 per component). Empty slots count as Common. Higher rarity pools unlock with Compound Level: Legendary at L4, Mythic at L6, Divine at L8. Drop odds are published and a bad-luck-protection (pity) system guarantees dry streaks on the top tiers can't run forever.
Slot compatibility: Oil Rig components fit only in Oil Rigs, Mining Shaft components fit only in Shafts. Each component has a specific slot (you can't put a Derrick Tower in a Pump Jack socket).
Use the Inventory page to move components between nodes — unequip from one, equip on another. The displaced component falls back to your locker.
Every slot, every rarity

6. Earning & Claiming
Rewards accrue continuously, per second, based on:
- Your grow-power (Formula D multiplier summed across your nodes' components)
- Your share of total network grow-power — capped at 30% per user
- The global halving emission rate E(t) (see section 9)
There is no new-player multiplier. Every operator is paid on identical terms — your rewards come from your components and your share of the network, never from how recently you joined.
Pending rewards are kept server-side and streamed to your HUD every ~10s. When you Claim All, every node's pending balance is zeroed and the reserve wallet pays out the net amount to your wallet (2% fee retained in the reserve to keep emissions solvent). Claims have a 1-hour cooldown per wallet.
Crate installs and compound upgrades internally accrue first, so you never lose production between actions — you're always paid at the rate you actually had for the time you had it.
USO rewards — Oil Rigs only
On top of $OSR, oil rigs earn USO (United States Oil Fund — an oil ETF issued on-chain as a Robinhood Stock Token). Every OSR trade on the public OSR/USO market pays a 0.5% fee in USO to the protocol; that USO is what gets shared with rig owners. Mining Shafts do not earn USO.
To earn USO you need both:
- Compound Level 5 or higher (your wallet-wide level — see section 7). Minting a rig alone is not enough.
- At least one Oil Rig deployed.
How it is shared:
- By stake, automatically. Every 2 minutes the USO that arrived since the last split is divided among every eligible player in proportion to their oil-rig grow-power — the same component-rarity-and-condition number that sets your OSR production, summed across all your rigs. More rigs, or better-kept rigs, mean a larger share. There is nothing to press: it lands as pending on its own.
- Your share is your share of the network. There is no per-wallet cap: a wallet holding a tenth of all eligible grow-power receives a tenth of every split, and 100% of each pool is paid out. Because grow-power rises steeply with component rarity, a mythic or divine part changes your share by far more than an extra common rig does.
- Timing does not matter. New USO reaches the reserve about every 15 minutes, not continuously, and is split at the next tick whether or not you are online. The Real-World Asset Rewards panel shows the USO waiting for the next split, how many players qualify, and your estimated share.
To receive it:
- Open the Real-World Asset Rewards panel in the HUD and press Claim on the USO row. No fee is taken on a USO claim.
- USO and OSR are two separate claims. Claim Rewards on your rigs pays out OSR only and never touches your USO balance; the USO Claim button pays out USO only and never touches your OSR.
- The USO is delivered in kind: real USO tokens land in your own wallet on Robinhood Chain. It is a token, not cash — selling it back costs a small market spread plus gas (see the selling section of the panel).
Tip: it is not a per-rig dividend. Your share of each window is your claimed OSR divided by everyone's eligible claimed OSR, so claiming regularly matters more than owning many rigs, and your OSR earnings are unaffected either way.
7. Compound Levels
Your Compound Level (L1 → L10) is your wallet-wide progression track. Each upgrade costs $OSR — from 500 OSR for L2 up to 60,000 OSR for L10, split 50/30/20 burn / reserve / treasury — plus a flat ETH fee. Each level unlocks:
- More node slots per family (2 at L1 → 8 at L10; shafts +2/+3/+4 bonus at L5/L7/L9)
- A higher daily crate limit (3/day at L1 → 20/day at L10, per node type)
- Higher rarity pools (Legendary at L4, Mythic at L6, Divine at L8)
- USO rewards at L5 — from Compound Level 5 your oil rigs start earning USO on top of $OSR (see USO rewards)
Upgrades have a 12-hour cooldown. In a hurry, you can expedite: pay the on-chain expedite fee to skip the cooldown for one upgrade (the fee goes to the treasury).

9. How emission works
OSR uses a halving emission curve. Global OSR issuance starts at 262 OSR/sec at launch and halves every 7 days until the lifetime supply is fully paid out.
E(t) = 262 OSR/sec × 0.5 ^ (t / 7d) Day 0 : 22.6M OSR emitted Day 7 : 50% of lifetime already emitted Day 14 : 75% emitted Day 30 : 95% emitted Lifetime total: 228.6M OSR (reserve of at least this bought at launch; fixed 1B supply)
Each user earns a share of each second's emission, proportional to their grow-power (sum of component multipliers across their nodes):
user_rate = min(your_gp / network_gp, 30%) × E(t)
Two key mechanics:
• Share cap: no user can capture more than 30% of emission
(prevents lottery-in-thin-network wins)
• Denominator floor: network_gp is floored at 2000 GP, so a
thin network cannot hand early players the whole curveWhy does emission halve? To front-load excitement during the first 2 weeks while still leaving meaningful yields for latecomers. By day 14, 75% of lifetime OSR has been distributed — what remains is split by grow-power, so a latecomer who builds a strong rig still earns a real share of the tail.
You can always see current global emission and your share on the Reserve Vault page — it's fully public.
