The Furnace

The Furnace is the lock engine at the center of the CLAIM stream. Every time someone takes the Crown, 25% of their ETH flows to Barons — players who locked CLAIM in the Furnace. The more veCLAIM you hold, the larger your share. And the Furnace gives you a bonus on top of what you lock, accelerating your position from the start. There are no user-to-user lock transfers — lock creation, Make Offer fills, listings, and Sell now all settle through the Furnace.

The bonus engine

The Furnace doesn’t just lock your CLAIM — it adds extra veCLAIM on top. This bonus is the core incentive to lock through the Furnace rather than simply holding CLAIM.

Where does the bonus come from? The protocol mints a dedicated Furnace emission stream — 5 CLAIM/s at launch, decaying to ~0.56 CLAIM/s over two years. This stream flows directly into the Furnace reserve, which funds every bonus.

The reserve also grows from sellback haircuts. As the reserve grows, bonuses can be more generous; when heavy locking drains it, bonuses cool down.

What affects the bonus:

Duration: Longer locks earn a much better bonus. The bonus scales with a duration weight — see the table below.
Entry size: Smaller entries tend to get better bonus rates than large ones.
Recent activity: Heavy locking activity cools the bonus down. After a burst, the bonus recovers over roughly 3 hours.

The maximum bonus any single entry can receive is 100% of the CLAIM locked (i.e., you can at most double your position).

Duration weight (how much duration matters):

Duration	Weight	Relative bonus
7 days	1%	Minimal
14 days	1.75%	Minimal
21 days	3%	Low
30 days	5%	Low
90 days	15%	Moderate
180 days	40%	Strong
270 days	65%	High
365 days / AutoMax	100%	Maximum

The bonus is quoted live before you confirm and updates as you adjust duration.

Example: Locking 10,000 CLAIM for 1 year with AutoMax at a 40% bonus gives you 14,000 veCLAIM (10,000 principal + 4,000 bonus). That same 10,000 CLAIM locked for just 30 days has only a 5% duration weight (compared to 100% for a 1-year lock), so the effective bonus is dramatically lower — in typical conditions perhaps ~2% (200 CLAIM). The exact rate depends on the reserve and recent activity, but the duration weight is the biggest lever. The bonus is always shown in the live quote before you confirm.

A share of each lock bonus also funds LP staker rewards, streamed smoothly over time — creating a self-reinforcing loop between locking activity and liquidity.

Bonuses beyond entry:

The entry bonus isn’t the only way the Furnace rewards you. Two additional mechanisms grow your position after the initial lock:

Extension bonus: When you extend a lock’s duration, the Furnace awards a bonus on your existing locked CLAIM for the extra time you commit — no new CLAIM needed. The same duration-weight curve applies: days near the top of the range carry more weight per day than days near the bottom. See Extension bonus for details.
AutoMax automatic growth: AutoMax locks receive the extension bonus automatically — protocol keepers trigger it once per day, so your lock compounds hands-free with no gas cost. This is one of the biggest advantages of choosing AutoMax. See Duration and AutoMax for details.

How to enter the Furnace

There are two paths: Lock Now (instant) and Make Offer (patient).

Lock Now

Lock Now enters the Furnace immediately at the current live quote.

Open Furnace → Lock Now
Choose your input: CLAIM or ETH
Set your amount (minimum 1,000 CLAIM equivalent for new locks)
Choose a lock duration (7 days – 1 year, or AutoMax)
Review the quote: your estimated veCLAIM output includes the bonus
Confirm the transaction

Entry token defaults: If you hold CLAIM, it’s preselected. Otherwise the app defaults to ETH. Non-CLAIM entries are swapped to CLAIM in the same transaction.

Lock destination: The app auto-selects the best destination lock for you. A dropdown lets you override the choice or create a new lock (minimum 1,000 CLAIM for new locks). See Managing your position below for details.

Make Offer

Make Offer is the patient way in. You set a target bonus and the Furnace executes automatically when conditions are right.

Open Furnace → Make Offer
Set your CLAIM budget (held in escrow; minimum 10,000 CLAIM)
Set your target bonus — the minimum bonus rate you’ll accept
Set an expiry (default 30 days, max 90 days)
Set output slippage, lock duration, and destination
Confirm

Your CLAIM sits in escrow until the live bonus meets your target (before expiry), then the Furnace locks it automatically. If your chosen destination lock becomes ineligible before execution, the router falls back to creating a new lock instead. That fill can revert if the remaining budget is below the 1,000 CLAIM new-lock minimum. You can cancel anytime to get your CLAIM back.

Make Offer is useful when the current bonus is low and you want to wait for a better window without watching the screen.

Eternal Lock

Eternal Lock is the quick path into the Furnace. It creates a new AutoMax lock and configures shareholder royalties auto-compound to target it — in a single flow. Forging executes two onchain transactions: a Furnace entry (ETH equivalent of 1,000 CLAIM, converted and locked at 365 days AutoMax with full bonus) followed by an auto-compound configuration targeting the new lock. Every future royalty payout then routes through the Furnace, locks with a bonus, and compounds automatically.

Scope: shareholder royalties only. LP Vault rewards (see Liquidity & LP Vault) and king auto-lock are not affected. Eternal Lock does not prevent additional standard Furnace locks.

How to forge: Open the Eternal Lock panel from Furnace, Overview, or Locks → Forge Eternal Lock → review ETH cost, bonus preview, and auto-compound settings → Continue (first-time warning gate) → Forge and confirm two wallet transactions.

Revoking: Eternal Lock is not permanent. Disable auto-compound from the Locks page to stop compounding (ETH accrues for manual collection). Disable AutoMax on the lock itself to start a 1-year countdown to expiry (see Locks — AutoMax). Disabling one does not disable the other — to fully exit, disable auto-compound first, then AutoMax.

What you earn: royalties

As a veCLAIM holder (a Baron), you earn ETH royalties from every takeover. Each takeover splits 25% of the ETH to the Barons pool, distributed proportionally by veCLAIM balance.

The very first (genesis) takeover routes 100% of its cost to Barons, since no previous King exists to receive the 75% share.

Collecting royalties

You choose how to receive your accrued ETH. Both flows are available from Overview and Locks.

Collect ETH (default): Withdraw accrued ETH directly to your wallet. Liquid, immediate.
Collect & Lock (optional): Route your ETH through the Furnace — it swaps to CLAIM, locks it with a bonus, and grows your veCLAIM.

Auto-compound

You can automate Collect & Lock so an authorized maintainer can handle it for you. In normal operation that is the allowlisted keeper; owner break-glass remains available for recovery:

Open Collect & Lock from Overview or Locks and toggle Enable auto-compounding
Choose an existing eligible destination lock and target duration (the UI may preselect one for you; click to override)
The allowlisted keeper normally executes periodically when you have accrued ETH

Auto-compound behavior:

Destination must already exist and be eligible when you configure it
Never creates a new lock during execution
Adding capital to an existing lock does not change its duration
AutoMax destinations keep their 1-year behavior
Preferences are remembered per wallet until you change them

Auto-compound uses a default maximum slippage tolerance of 5%. During volatile conditions, the official keeper may skip your compound if slippage exceeds this limit — your ETH stays accrued for the next attempt.

Auto-compound pauses automatically if the destination lock becomes ineligible (listed on Market, expired, or no longer owned by you).

For a one-action setup, see Eternal Lock above.

Managing your position

Duration and AutoMax

Lock duration ranges from 7 days to 1 year. Longer locks produce more veCLAIM and earn a higher bonus.

AutoMax keeps the lock permanently at maximum duration (1 year), preventing veCLAIM from decaying. AutoMax locks also receive automatic daily extension bonuses from protocol keepers — your lock grows over time without any action or gas on your part. As long as AutoMax is on, your lock maintains peak royalty-earning power and compounds hands-free. To eventually unlock your CLAIM, disable AutoMax first — this starts a 1-year countdown to expiry.

Extension bonus

When you extend a lock’s duration, the Furnace rewards you with a bonus on your existing locked CLAIM for the additional time you commit. No new CLAIM is needed — the bonus comes from the Furnace reserve, just like the bonus you received when you first locked.

Two factors determine your extension bonus: how many days you add and where on the curve those days fall. The duration-weight curve accelerates toward the maximum — days near the top of the range (e.g., 350 to 365) carry more weight per day than the same number of days near the bottom (e.g., 30 to 45). So extending a long lock by a little can outperform extending a short lock by the same amount.

AutoMax locks receive this bonus automatically — it’s one of the biggest advantages of choosing AutoMax. Protocol keepers trigger extension bonuses for AutoMax locks once per day. You pay no gas and take no action — keepers handle it. Your lock grows over time just by staying committed, compounding hands-free.

Non-AutoMax locks can still earn the bonus, but you must manually extend via the Extend flow on the Locks page each time. The live bonus is shown before you confirm.

Example: You have a lock with 10,000 CLAIM and 60 days remaining. You extend to 365 days. The Furnace computes the incremental duration weight (the difference between the 365-day weight and the 60-day weight) and awards a bonus on your 10,000 CLAIM for that increment. The exact amount depends on the current Furnace state, and is always shown in the quote before you confirm.

Lock destination (smart defaults)

For manual Furnace entries, the app auto-selects a destination lock:

AutoMax intent (default): picks your newest eligible AutoMax lock (highest tokenId). If you have none, creates a new AutoMax lock when allowed.
Fixed-duration intent: picks the eligible non-AutoMax lock with the highest remaining time that does not exceed your chosen duration. Tie-break: highest principal, then newest.
No eligible locks: creates a new lock (requires 1,000 CLAIM minimum).

For auto-compound setup, the UI may also preselect an existing eligible lock for convenience, but the onchain v1 auto-compound config must point to an existing eligible destination lock. If that destination later becomes invalid, auto-compound pauses instead of creating a new lock.

For manual entries, the dropdown shows the selected lock (e.g. “Lock #2 — 6,110 CLAIM — AutoMax”) or “New lock”. Click it to choose a different destination. Locks with less than 7 days remaining are greyed out and cannot be selected as destinations.

Adding capital to an existing lock does not change its duration. To extend a lock’s duration (and earn a bonus on existing capital), use the Extend flow on the Locks page.

Duration slider

The Lock duration section has preset buttons (30d / 90d / 180d / 270d / 365d) plus a continuous slider that covers the full range (7d–365d). AutoMax is a separate toggle; default is AutoMax on. Dragging the slider below 365 days disables AutoMax. Moving back to 365 days does not re-enable AutoMax — use the AutoMax toggle for that. The effective bonus updates live as you change duration.

Exiting the Furnace

There are three ways to exit:

Wait for expiry

Disable AutoMax (if enabled) to start the countdown. When the lock expires, veCLAIM reaches zero and you can unlock your CLAIM principal. This is the no-cost exit, but you stop earning royalties as veCLAIM decays.

Sell now (instant liquidity)

Sell your lock back to the Furnace for liquid CLAIM immediately.

Open Furnace → Sell Now
Select the lock to sell
Review the estimated CLAIM payout
Set your slippage tolerance (determines your minimum payout floor)
Confirm

The lock is burned and you receive CLAIM in your wallet. Sell now is fast but comes at a discount — the Furnace applies a dynamic spread (haircut) to the payout. The retained CLAIM is split between the Furnace reserve (replenishing future bonuses) and the LP rewards stream (benefiting LP stakers).

Example: You have a lock with 14,000 CLAIM (10,000 principal + 4,000 bonus) and 8 months remaining. The Furnace might quote you 8,000 CLAIM back — a ~43% haircut. If the bonus environment is low and your lock has less time remaining, the spread shrinks and you get more back. The exact quote is always shown before you confirm.

What affects sellback pricing:

High bonus environment → higher spread (bigger discount)
Low bonus environment → lower spread (smaller discount)
More remaining time on the lock → larger spread

Spread range:

Minimum: 1.2% (locks with 7 days or less remaining)
Maximum: 70%
Round-trip floor: the protocol targets at most ~25% loss if you lock for 1 year and immediately sell back. Shorter locks have proportionally smaller worst-case losses.
Burst sell-impact surcharges (heavy sell volume within a 3-hour window) can temporarily exceed the round-trip floor.

If your lock is listed on Market, Sell now auto-delists it first.

List on Market (limit sell)

Post a listing with a minimum CLAIM payout you’ll accept and an expiry. The listing settles through the Furnace when the quote meets your floor. This lets you set a price and walk away.

See Market for listing details.

Advanced details

Slippage protection

Every Furnace action has a safety floor:

Lock Now / Collect & Lock: you set a minimum veCLAIM output. If the bonus moves against you, the transaction reverts and you keep your CLAIM (you still pay gas). On ETH swap paths, a short swap deadline (300 seconds) prevents stale execution.
Sell now: you set a minimum CLAIM payout plus a short anti-stale deadline shown in the Sell now flow. If the quote drops below your floor or the deadline passes, the transaction reverts and you keep your lock.
Market listing: your minimum payout and expiry are enforced onchain.

If a quote moves between when you review it and when you sign: refresh, retry, or split large actions into smaller ones.

LP Vault routing

Harvest & Lock in the LP Vault routes LP rewards through the Furnace into veCLAIM, combining LP yield with the Furnace bonus.

Approvals

Locking CLAIM: approve the Furnace to spend your CLAIM (one-time)
Make Offer: approve CLAIM to the MarketRouter for escrow (one-time)

The app prompts you when an approval is needed. Selling and listing a lock do not require a separate NFT approval — the MarketRouter has built-in transfer privileges on veCLAIM.
