The Furnace

TL;DR — Lock CLAIM in the Furnace to receive veCLAIM with a bonus on top. Enter via Eternal Lock, Lock Now, or Make Offer. Exit via wait for expiry, Sell now (instant), or List Lock (patient). All trades route through the Furnace — no user-to-user transfers.

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 holding CLAIM passively.

Where does the bonus come from? A dedicated Furnace emission stream mints CLAIM directly into the Furnace reserve — that reserve funds every bonus paid on a lock. See Genesis — The two emission streams for the launch context and emission schedule.

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: For eligible AutoMax locks, the keeper processes extension bonuses during the settlement window, at no gas cost. See Duration and AutoMax for details.

How to enter the Furnace

Three paths: Eternal Lock (one-flow setup), Lock Now (instant), and Make Offer (patient). Step-by-step walkthroughs live in the tutorials.

Eternal Lock

Eternal Lock is the single-flow path into the Furnace. It creates a new AutoMax lock and configures shareholder royalties auto-compound to target it — in a single flow. Forging submits a Furnace entry (ETH equivalent of 1,000 CLAIM, converted and locked at 365 days AutoMax with full bonus) plus an auto-compound configuration targeting the new lock. Wallets that support batching can combine that into one wallet approval; others fall back to a follow-up config confirmation. After setup, shareholder royalties can route through the Furnace, lock with a bonus, and compound automatically while the destination remains eligible.

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, Walkthrough, or Locks → Forge Eternal Lock → review ETH cost, bonus preview, and auto-compound settings → Continue (first-time warning gate) → Forge and confirm the wallet prompt. If your wallet does not support batching, the app follows with a separate auto-compound configuration confirmation. For the full walkthrough, see Forge Eternal Lock.

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.

Lock Now

Lock Now enters the Furnace immediately at the current live quote. For the full walkthrough, see Enter the Furnace.

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. Escrow CLAIM, set a target bonus, and the Furnace executes automatically when the live bonus meets your target before expiry. Useful when the current bonus is low and you want to wait for a better window without watching the screen.

Minimum budget is 10,000 CLAIM. The escrow holds your CLAIM until the offer fills or you cancel; if your destination lock becomes ineligible before execution, the router falls back to creating a new lock (requires 1,000 CLAIM minimum at fill time).

For the full step-by-step, see Market — Make Offer.

What you earn: royalties

Locking through the Furnace makes you a Baron — a veCLAIM holder entitled to 25% of every takeover’s ETH, weighted by your share of total veCLAIM.

Two collection paths are available from Overview: Collect ETH (liquid, default) and Collect & Lock (compounds through the Furnace into more veCLAIM with a bonus). Auto-compound automates the second path.

For accrual mechanics, the full collection reference, auto-compound configuration, and the slippage and pause-on-ineligible rules, see Royalties (Barons).

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. For eligible AutoMax locks, the keeper also processes automatic extension bonuses during the settlement window — your lock grows over time without manual action or gas on your part. While AutoMax remains enabled, your lock maintains peak royalty-earning power. To 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.

For eligible AutoMax locks, this bonus is processed automatically. The keeper processes extension bonuses during the settlement window. You pay no gas and take no action. Your lock grows over time while AutoMax remains enabled.

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. The lock is burned and you receive CLAIM in your wallet. The retained CLAIM splits between the Furnace reserve (replenishing future bonuses) and the LP rewards stream (benefiting LP stakers).

For the step-by-step, see Market — Sell now or the full walkthrough in Sell to Furnace.

Why the haircut exists. Sell now is fast but priced at a discount — the Furnace applies a dynamic spread that protects the reserve and LP rewards stream from one-way drain.

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.

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

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 and List a Lock for the full walkthrough.

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 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 Market contract has built-in transfer privileges on veCLAIM.
