Core concepts
What is ClaimRush
ClaimRush is an onchain king-of-the-hill game with two core loops:
| Loop | Action | Reward |
|---|---|---|
| Takeover (Crown) | Pay ETH to take the Crown → become King | Mine CLAIM; 75% of next takeover when dethroned |
| Furnace (Barons) | Lock CLAIM → veCLAIM (NFT) | 25% of every takeover (ETH royalties) |
Everything else supports one of these loops.
The Mine, the Crown, and reigns
- The Mine has exactly one King at a time.
- A reign is the period a King holds the Mine.
- A reign ends when someone else takes over.
You can browse reign history on the Crown page and share reign permalinks.
CLAIM and veCLAIM
| Token | Description |
|---|---|
| CLAIM | The game token. Lock CLAIM, swap CLAIM, or provide LP. |
| veCLAIM | Voting escrow balance from locking CLAIM. Your lock is an NFT. |
ve mechanics:
- More CLAIM locked = more ve
- More time remaining = more ve
- ve decays toward 0 as the lock approaches expiry
Takeovers and price
- Takeovers are paid in ETH.
- After each takeover, the price doubles, then decays over ~1 hour toward the floor (0.001 ETH).
- UI labels: Cost: High / Mid / Low (timing context, not a promise).
Payouts: where ETH goes
Every takeover ETH payment is split:
| Recipient | Share | Timing |
|---|---|---|
| Previous King | 75% | When dethroned |
| Barons (veCLAIM holders) | 25% | Accumulates per takeover |
The Furnace
The Furnace is the only counterparty for lock creation and settlement.
It can:
- Swap ETH → CLAIM and lock it (one step)
- Lock CLAIM directly
- Add a bonus on top
See Furnace for entry defaults, bonus mechanics, quotes, and sellback.
Market
Market is the lock management board.
Key invariant: The Furnace is the only counterparty. There are no user-to-user lock transfers.
You can:
- Sell now (Market sell): sell a lock immediately to the Furnace with
minClaimOutas minimum payout (slippage-derived) - Market listing (Limit sell): post a listing with
minClaimOutminimum payout and an expiry (expiresAtTime) - Delist a listing
- Buy intent (Limit buy): bonus target escrow (patient Furnace entry) — escrow CLAIM Input amount (
budgetClaim) + Expiry (expiresAt) and a minimum output trigger (minVeOut, or target bonus)
See Market for listing rules and settlement.
LP Vault (advanced)
Stake Aerodrome WETH/CLAIM LP → earn CLAIM rewards. 7-day unbonding period.
Protocol guarantees
- 0% platform fee
- One active King at a time
- Fixed takeover split (75% King, 25% Barons)
- The Furnace is the only counterparty for lock trading
