Locker

The ULAB Locker is the module where users lock ULAB LP and receive xULAB.

Core ideas:

• You must lock ULAB LP in the Locker to obtain xULAB.

• Only users who lock enough ULAB LP vs. their Supply become Emission Eligible for ULAB rewards.

• xULAB is non-transferable and only comes from locked LP.

What Is Locked?

The Locker accepts ULAB-based LP tokens, such as:

• ULAB–MOVE LP

• ULAB–ETH LP

• ULAB–Stables LP

Additional ULAB LP pairs and chains can be added by the protocol / governance.

Reward Eligibility (Emission Eligibility)

ULAB rewards in each market are distributed only to users who satisfy an Eligibility condition.

Definitions (per market, Supply side):

• SupplyValue = total value (USD) you supply in that market

• LockedLPValue = total value (USD) of your locked ULAB LP

You are Emission Eligible in that market if:

$$LockedLPValue≥0.03×SupplyValue$$

Notes:

• Borrow amounts are ignored for eligibility (only Supply matters).

• Example:

  • If you supply $1,000 in a market:

  • $0.03×1,000=30$

    → you must lock at least $30 worth of ULAB LP to stay eligible.

If market or LP prices move and:

$$LockedLPValue<0.03×SupplyValue$$

then:

• You lose Emission Eligible status for that market.

• A Kick mechanism can be executed by protocol logic:

  • Marks your position as ineligible.

  • UI can notify you (e.g. “Not eligible for rewards — lock more ULAB LP”).

2.2.1 Eligibility Summary

Item	Description
SupplyValue	Your supplied notional (USD) in the market
LockedLPValue	Your locked ULAB LP value (USD)
Eligibility condition	LockedLPValue ≥ 3% × SupplyValue
Below threshold	You can be kicked out of Emission Eligible status
Regain eligibility	Lock more ULAB LP or reduce SupplyValue

If you are not Emission Eligible, you receive 0 ULAB from that market, regardless of your xULAB, Score, or boost.
