There are 7 lands — one per continent — on a single world map. You seize a continent with ETH, earn MRDN while you hold it, and exit when someone outbids you — taking 85% of the next seize price in ETH.

MRDN is fair-launched. The protocol does not pre-fund a mining vault and does not mint a team allocation. Mining rewards come only from buybacks funded by seize ETH.

• Seven continents — scarcity by design
• Owner-only — no renters, no operators, no leases
• ETH for conquest — MRDN for mining and staking
• Transparent split on every seize: 85% · 3% · 10% · 2%
• Fixed floor step: +10% after each successful seize

1. 01Open the globe and select a continent.
2. 02Seize it by paying the current floor in ETH.
3. 03Hold to accrue MRDN mining from the buyback-funded vault.
4. 04Optionally stake MRDN to earn a share of the 3% ETH slice.
5. 05When outbid, receive 85% of the new seize price in ETH instantly.
6. 06Repeat on the same continent or expand across the world.

Each land maps to a real continent on the globe. Selecting it opens the command panel for seize, portfolio, and stake actions.

Weight is deterministic from land ID and does not change the seize price. It only affects how mining rewards are split among holders.

There is no per-continent premium at genesis. Hot continents rise because they flip more often — not because the protocol assigned them a higher starting price.

Genesis exception: when a land has never been owned, there is no previous owner. The 85% slice is redirected into the buyback path so early conquest still seeds the mining vault instead of minting phantom refunds.

• Genesis buyback path = 85% + 10% = 95% of seize ETH toward MRDN buyback
• Overbid buyback path = 10% of seize ETH toward MRDN buyback
• Rounding dust accrues to the protocol slice

MeridianMiner tracks each land’s effective weight and accrues rewards pro-rata. Claiming mining also refreshes activity on your lands.

• No pre-allocated 25% mining fund
• Rewards arrive only after successful buybacks deposit MRDN
• If buyback ETH queues (no router / thin liquidity), flush when the pool is ready

MeridianStake is a separate module. Stakers do not need to own land. Land holders do not need to stake. The two yield paths are complementary.

• Stake MRD → earn ETH from the global seize stream
• Claim ETH anytime rewards are pending (independent of unstake)
• If ETH arrives before anyone is staked, it residual-queues and flushes when stake appears

• Unstake is instant — no queue, no cooldown (COOLDOWN = 0)
• Withdraw any amount up to your staked balance in one transaction
• Pending ETH rewards remain claimable before or after unstake

Intended launch path: list MRDN on a fair-launch pad (Pons or Virtual) on Robinhood Chain, then deploy the game stack pointing at that token address. See LAUNCH.md in the repository for the operator runbook.

1. 01User calls Game.seize{value}(landId).
2. 02Game updates ownership and notifies Miner.
3. 03Game sends ETH to previous owner / Stake / Buyback / protocol accrual.
4. 04Buyback swaps ETH→MRDN (or queues) and deposits into Miner.
5. 05Holders claimMining(); stakers claimEth().

• Smart-contract risk — contracts may contain bugs; audits are not implied by this document
• Market risk — land floors can rise faster than you can exit if you are not outbid
• Liquidity risk — buybacks depend on a live MRDN/ETH market and router
• Opportunity cost — ETH locked in a land earns only via mining / future outbid, not via guaranteed yield
• Chain risk — Robinhood Chain availability, fees, and finality apply
