Allocations & Magnitude

When an operator opts into an AVS, they allocate a portion of their stake to secure that service. EigenLayer uses a magnitude system to manage these allocations, and understanding it helps you interpret what you see on operator profiles.

Shares vs Magnitude​

These two concepts are often confused, but they represent different things:

ConceptWhat It RepresentsExample
SharesThe absolute amount of stake an operator holds in a strategy100 stETH worth of shares
MagnitudeThe percentage of that stake allocated to AVS work50% allocated to AVSs

Shares come from delegators. When someone delegates stETH to an operator, the operator's share balance increases.

Magnitude is the operator's decision about how much of those shares to put "at risk" for AVS services. It determines how much stake is actually securing each AVS.

How Magnitude Works​

Max Magnitude​

Every operator starts with a max magnitude of 100% for each strategy. This represents their total available capacity.

The critical thing about max magnitude: it only goes down, never up. The only event that reduces max magnitude is slashing. If an operator is slashed for 10% of their stake in a strategy, their max magnitude permanently drops to 90%.

Encumbered Magnitude​

Encumbered magnitude is the portion of max magnitude currently allocated to AVS operator sets. It increases when the operator takes on new AVS commitments and decreases when they deallocate.

The rule: encumbered magnitude <= max magnitude. An operator can never allocate more than their max allows.

Utilization Rate​

Utilization Rate = (Encumbered Magnitude / Max Magnitude) x 100

This tells you what percentage of the operator's available capacity is in use.

UtilizationMeaning
30%Plenty of room for new commitments
70%Moderate --- still has buffer capacity
90%Very high --- almost fully committed
100%Fully allocated --- no room for additional AVSs

From Shares to USD​

The dashboard shows allocation values in USD. Here's how that conversion works:

1. Start with the operator's total shares in a strategy
2. Multiply by the magnitude ratio (encumbered / max) to get allocated shares
3. Multiply by the exchange rate to convert shares to underlying tokens
4. Multiply by the token price in USD

Example​

Total shares:           100 (in stETH strategy)
Encumbered magnitude:   50% (half allocated to AVSs)
Max magnitude:          100% (never slashed)
Exchange rate:          1.05 (stETH to ETH conversion)
Token price:            $2,000

Allocated shares  = 100 x (50% / 100%) = 50
Underlying tokens = 50 x 1.05 = 52.5 ETH equivalent
USD value         = 52.5 x $2,000 = $105,000

Why Allocations Matter for Risk​

Utilization Risk​

Operators with high utilization (above 70%) score lower on the Economic Score's utilization component. High utilization means:

  • Less flexibility --- can't easily take on new AVS commitments
  • Higher slashing exposure --- most of their stake is at risk
  • Less buffer --- limited room to adjust allocations if market conditions change

AVS Concentration Risk​

An operator's allocations should ideally be spread across multiple AVSs. If most of the allocation goes to a single AVS and that AVS has a slashing event, the impact is concentrated.

The Economic Score measures this using the HHI index on allocation values. Diversified allocations score higher.

Registration vs Allocation​

On operator profiles, you'll see both:

  • Registered AVSs --- services the operator has opted into
  • Active Allocations --- where stake is actually committed

An operator might be registered with 10 AVSs but only allocating to 3. The allocations are what matter for risk --- registration alone doesn't commit any stake.
