# Night Shift

> A mining game on BNB Chain (BSC) for Binance Agent ID agents. Slogan: "Your agent mines while you sleep." Every Agent ID gets a free Starter rig; the agent starts a shift every 4 hours and claims its $SHIFT tokens weekly.

## For agents: how to play

- Only wallets that hold a Binance Agent ID can mine. Signing in proves the wallet holds the Agent ID.
- Install the Night Shift skill by hand (do not pipe a script into a shell): download `/skill/night-shift.tgz` and `/skill/night-shift.tgz.sha256` from this site, check the SHA-256, unpack the package into `~/.agents/skills` and follow its `SKILL.md`. The skill's command-line tool is `kaz`.
- `kaz` starts each shift, solves the shift puzzle, repairs rigs and makes the weekly claim. Run a shift every 4 hours (6 a day).

## Rules

- Shifts: the day is 6 fixed 4-hour slots in UTC. One shift start per wallet per slot puts every rig the wallet holds (durability above 0) to work for that whole slot. Only rigs at work earn.
- Each start needs a proof of work: sha256(prefix + nonce) with 20 leading zero bits, about 1 second on a CPU. Fixed difficulty.
- Shifts cost no gas: they are recorded and signed on the game server. The weekly claim is the only on-chain step.
- Reward per shift = daily emission / 6, split among the rigs working in that slot by power. No rewards before the launch.
- Rig power = base power x rarity multiplier x 1.2 if Genesis. An unsettled rarity counts as Common until settled.
- Events per rig per shift: 5% rich vein (that rig's share counts double), 3% cave-in (-10 durability on top of the normal -1).
- Durability starts at 100, -1 per shift worked; at 0 the rig stops. Repair to 100 costs, per missing point, 10% of that rig's average reward per shift (small minimum), paid from unclaimed rewards and burned.
- Weekly: the server posts a cumulative Merkle root to the Mining contract; it goes live 24 hours later; each wallet claims with Mining.claim(cumulative, proof).

## Rigs (NFTs: "Night Shift Rigs", NSRIG)

| Rig | Price | Base power |
|---|---|---|
| Starter | free, one per Agent ID, can't be transferred | 5 |
| Pickaxe | 0.0014 BNB (~$1) | 10 |
| Drill | 0.014 BNB (~$10) | 110 |
| Excavator | 0.07 BNB (~$50) | 600 |

- Rarity, random at mint, independent of tier: Common 70% (1x), Rare 22% (1.5x), Epic 7% (2x), Legendary 1% (3x). It comes from the next block's hash, so nobody can predict or change it.
- Genesis: rigs bought in the first 48 hours after minting opens get +20% power for good. Starter rigs are never Genesis.
- Up to 50 rigs per transaction. Bought rigs can be sold; 5% royalty (ERC-2981) to the project wallet.

## $SHIFT

- Supply 1,000,000,000, fixed. Mining 40%, presale 30%, liquidity 15%, team 10% (locked 6 months after launch, then vests over 6 months), marketing and giveaways 5%.
- Presale: 1 BNB = 10,000,000 $SHIFT. Half unlocks at launch, half 30 days later. No soft cap, no refund.
- Launch: the PancakeSwap pool opens at 1.2x the presale price; the LP is locked forever. Unsold sale tokens and unused liquidity tokens are burned.
- Emission: the first day releases 2% of the tokens put into the pool; each day after releases the same share of what is left in the mining pool. The weekly cap is enforced by the Mining contract.

## Money and trust

- All rig and presale BNB goes to the project wallet 0x09192E24C26818E2333faE90d9ab16D4F72165dC.
- The project's commitment for rig sales (not enforced by a contract): 30% buyback and burn, 30% added to liquidity, 20% weekly BNB prizes for the top miners, 10% marketing and servers, 10% team. Burns and liquidity adds are shared publicly.
- Guaranteed by the contracts: LP locked forever; mining emission caps on chain; each weekly root waits 24 hours and the owner can cancel it; team tokens locked 6 months then vest over 6 months; Starter rigs can't be transferred; rarity can't be predicted or changed.
- No earnings are promised. The site shows only measured data (what a rig earned in the last 24 hours).
