Enter the Furnace (Lock Now / Make Offer)

Where this fits: Furnace loop in the CLAIM stream · Full guide: The Furnace

Goal: Create or grow a veCLAIM lock to earn royalties.

The Furnace is the only source of locks — you don’t buy them from other users. This tutorial covers both entry paths: Lock Now (instant) and Make Offer (patient).

Time

  • Lock Now: 3–10 min
  • Make Offer: 3–10 min to place (execution depends on Furnace state)

You need

  • Wallet on Base (8453)
  • ETH for gas
  • CLAIM or ETH to lock

Entry paths

  1. Lock Now (instant) — enter the Furnace immediately at the current quote
  2. Make Offer (patient) — set a target bonus and enter automatically when conditions are right

Tip: Use Lock Now when the current bonus looks good and you want to enter immediately. Use Make Offer when the bonus is low and you’d rather wait for a better window.

Lock Now

Think of it as: “I’m putting 1,000 CLAIM (or 1 ETH) into the Furnace — tell me how much veCLAIM I’m getting.”

Steps

  1. Open Furnace from the navigation bar
  2. Pick input: CLAIM (direct) or ETH (swapped to CLAIM)
  3. Enter amount
  4. If your wallet is not yet connected, select Connect wallet and approve the connection
  5. Choose duration: 7 days – 1 year (or AutoMax)
    • Destination lock is auto-selected (click the dropdown to change)
    • Locks with less than 7 days remaining are greyed out in the destination dropdown
    • If you have no eligible locks, the app creates a new one (min 1,000 CLAIM)
  6. Review the live quote:
    • Estimated output — how much veCLAIM you’ll receive (principal + bonus)
    • Minimum output — your safety floor (derived from slippage setting)
    • On ETH swap paths, a short swap deadline (300s) prevents stale execution
  7. Confirm in wallet

Make Offer (patient entry)

Steps

  1. Open Furnace from the navigation bar → select the Make Offer tab
  2. If your wallet is not yet connected, select Connect wallet and approve the connection
  3. Set your CLAIM budget (held in escrow; minimum 10,000 CLAIM)
  4. Set expiry (default 30 days, max 90 days)
  5. Set target bonus + output slippage
  6. Choose duration + destination (auto-selected; click to change)
  7. Confirm in wallet

Your CLAIM sits in escrow until the live bonus meets your target. 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. After creation, there is a 30-minute keeper grace period during which whitelisted keepers get first priority and the MarketRouter owner retains a documented break-glass path — after that, anyone can settle it if conditions are met. You can cancel anytime to get your CLAIM back.

Watch out: Make Offer escrows your CLAIM for up to 90 days. If conditions never meet your target, you can cancel anytime, but your CLAIM is locked in escrow until you do.

Success
