The Crown

The Crown is the competitive heart of ClaimRush — the entry point of the CLAIM stream. Pay ETH to take over the Mine, become King, and mine CLAIM for as long as you hold it. When someone dethrones you, you walk away with 75% of the ETH they paid. The other 25% flows to Barons as royalties — fueling the Furnace loop.

How takeovers work

Takeovers are priced in ETH.

After each takeover, the cost doubles — then decays over up to one hour toward the floor of 0.001 ETH. The app shows the current cost tier as High, Mid, or Low to give you timing context.

This creates a natural rhythm: takeovers are expensive right after someone takes the Crown, then become cheaper as time passes. Timing your entry when the cost is low means you risk less ETH for the same mining opportunity.

Low reference prices can reach the floor before the full hour. Example: Someone takes over at 0.01 ETH. The reference price jumps to 0.02 ETH. Over the next hour:

• At ~15 min: cost is ~0.015 ETH (High tier)
• At ~30 min: cost is ~0.01 ETH (Mid tier)
• At ~50 min: cost is ~0.003 ETH (Low tier)
• By ~60 min: this example reaches the 0.001 ETH floor

Taking over during the Low tier means you risk very little ETH, but you mine the same CLAIM/second as someone who paid at High tier.

If the ETH cost drops between when you load the page and when you confirm, any excess ETH is refunded. If someone else takes over before your transaction lands, it reverts — you keep your funds (minus gas).

Taking the Crown

1. Open Crown (route: /crown)
2. Check the current cost and tier
3. Press Takeover and confirm in your wallet

If the transaction reverts because someone took over first, refresh and retry. Under contention, reverts are normal.

Being King

While you hold the Crown, you mine CLAIM — the only way CLAIM is produced. The Crown page shows your reign timer, mined CLAIM balance, and the current takeover cost others would pay.

When do you receive mined CLAIM? CLAIM accrues while you hold the Crown, but tokens are minted and delivered only when your reign ends (when the next player takes over). By default they go to your wallet; enable auto-lock (see below) to route them through the Furnace into veCLAIM instead.

Example reign: Take over at 0.003 ETH during a Low tier window, hold for 40 minutes. Someone else takes over at 0.005 ETH — you receive 0.00375 ETH (75%), more than you paid, plus all the CLAIM you mined.

Lock mined CLAIM in the Furnace to grow your veCLAIM and earn royalties. You can also hold, swap, or provide LP.

Getting dethroned

When another player takes the Crown, you receive:

• ETH payout: 75% of what they paid, sent to your reign ETH recipient (default: your wallet)
• Mined CLAIM: All CLAIM mined during your reign, sent to your reign CLAIM recipient (default: your wallet)

If the ETH payout or an overpay refund transfer fails for any reason, it becomes available to withdraw from the app.

Auto-lock (optional): The takeover flow includes an auto-lock toggle:

• When enabled, mined CLAIM is routed through the Furnace into veCLAIM at dethroning instead of sent to your wallet
• Remember my choice persists the preference across sessions
• Configured per wallet; if the lock destination becomes invalid, auto-lock is skipped and CLAIM goes to your wallet as fallback

Payout recipients (advanced)

Each reign has two onchain recipients that can be configured:

• Reign ETH recipient: receives the 75% dethroned payout
• Reign CLAIM recipient: receives the mined CLAIM stream

For self-takeovers, both default to your address. For delegated (bot) takeovers, the ETH recipient defaults to the bot (so it can keep looping), while the CLAIM recipient stays with you unless you explicitly route it.

Recipients can be changed mid-reign via onchain transactions. If you use bots, keep Radar alerts on for “reign recipients changed.”

Bots (optional)

Some players use automation to take over on their behalf. This is optional and advanced.

How it works:

• You grant a bot Bot access — a time-limited delegation session with specific permissions
• The bot pays ETH and takes over for your address
• Your address becomes the King identity and mines CLAIM

Default routing for bot takeovers: the bot receives the ETH dethroned payout (so it can keep looping), while your mined CLAIM stays with you.

Setup: Header menu → Advanced → Bot access. See Bots & Automation for details.

Strategy tips

• Watch cost tiers. Low-cost windows are the best time to take over — you risk less ETH for the same mining opportunity. Use Radar alerts for “Cost: Low” notifications.
• Lock your CLAIM. Mining only produces value if you do something with the CLAIM. Locking in the Furnace compounds your position.
• Expect reverts under contention. When multiple players are competing for the Crown, failed transactions are normal. Retry quickly or use private sending (below).
• Private sending (advanced). Some wallets support private or MEV-protected transaction sending. Do not use RPC URLs from DMs.
