SLAC Explained

Shared Liquidity Amplification Coefficient: The metric that shows how hard your capital really works.

Your $100k Can Be in Multiple Places. Here's How We Measure It.

In our last post, we talked about vTVL—how your capital can effectively serve multiple chains by moving between them fast enough.

But there's a question we didn't answer: How do you measure that efficiency?

If your $100k serves Ethereum, then Base, then Arbitrum—how many times is that capital being utilized? 3x? 5x? 10x?

That's what SLAC measures.

SLAC (Shared Liquidity Amplification Coefficient) is the ratio of effective liquidity provided versus actual capital deployed.

Simple example:

You deploy $100k
That $100k provides liquidity across 3 chains
Effective liquidity delivered: $300k
SLAC = 3x

The higher your SLAC, the harder your capital works.

Why SLAC Matters More Than TVL

Traditional DeFi measures TVL. How much capital is locked?

SLAC measures productivity. How many times is that capital being used?

Two LPs, same capital deployed:

LP A (Traditional):

Deploys $300k across 3 chains
Each chain active 10% of time
Effective liquidity: $30k
SLAC: 0.1x (deployed $300k, provided $30k of utility)

LP B (Aqua0):

Deploys $100k in their wallet
Capital moves between 3 chains as needed
Active 60% of time across all chains
Effective liquidity: $180k
SLAC: 1.8x (deployed $100k, provided $180k of utility)

LP B deployed 1/3 the capital. Got 6x the productivity.

That's the power of high SLAC.

How SLAC Gets Calculated

SLAC is based on three factors:

1. Number of chains served

More chains = higher potential SLAC.

Serving 2 chains: max SLAC ~2x
Serving 5 chains: max SLAC ~5x
Serving 10 chains: max SLAC ~10x

2. Cross-chain movement speed

Faster movement = higher realized SLAC.

30 second bridge: capital is "in transit" too long, lower SLAC
5 second bridge (LayerZero V2): capital is productive 90%+ of time, higher SLAC

3. Activity distribution across chains

More evenly distributed activity = higher SLAC.

Only Ethereum active: SLAC ~1x (no benefit from cross-chain)
All chains equally active: SLAC approaches max (number of chains)

Formula (simplified):

SLAC = (Total liquidity provided across all chains) / (Capital deployed)

Where "liquidity provided" = sum of all swap volumes your capital facilitated.

Real SLAC in Action: A Day of Trading

Let's walk through actual performance to see SLAC in real terms:

You deploy: $100k

8:00 AM EST - US markets open

Base sees $2M in ETH/USDC swaps
Your $100k gets pulled to Base
Facilitates 8 swaps totaling $1.2M
Returns to Ethereum
Time active: 30 minutes

2:00 PM EST - European afternoon

Arbitrum sees $1.5M in WBTC/USDC trades
Your $100k gets pulled to Arbitrum
Facilitates 5 swaps totaling $800k
Returns to Ethereum
Time active: 20 minutes

6:00 PM EST - Asia evening prep

Ethereum mainnet picks up
Your $100k already on Ethereum (no pull needed)
Facilitates 12 swaps totaling $2M
Time active: 45 minutes

9:00 PM EST - Asia peak

Base active again (overlap with Asia trading)
Your $100k pulled back to Base
Facilitates 6 swaps totaling $900k
Returns to Ethereum
Time active: 25 minutes

Total for the day:

Swaps facilitated: $4.9M across 4 active periods
Capital deployed: $100k
Daily SLAC: 49x (provided $4.9M liquidity with $100k capital)

But wait—that's measuring volume, not time-based utilization.

Time-based SLAC:

Active time: 2 hours (30+20+45+25 min)
Total day: 24 hours
Utilization: 8.3%
Chains served: 3 (Ethereum, Base, Arbitrum)
Effective SLAC: ~2.5x (capital effectively present on 2-3 chains simultaneously through the day)

The difference? Volume-based SLAC measures total liquidity facilitated. Time-based SLAC measures effective omnipresence.

Both matter. We optimize for time-based SLAC because it directly correlates with fees earned.

What Different SLAC Levels Mean

SLAC < 1x: Traditional multi-chain LP. You deployed $300k, but only $200k is ever utilized. You're losing money on idle capital.

SLAC = 1x: Single-chain LP or perfectly optimized single-chain position. Your capital is fully utilized, but only on one chain.

SLAC = 2-3x: Cross-chain LP with good coordination. Your capital serves 2-3 chains effectively. This is where Aqua0 operates today.

SLAC = 5-10x: Theoretical max with current infrastructure. Your capital serves 5-10 chains with high activity. This is where we're heading.

SLAC > 10x: Future state with sub-second cross-chain messaging and 20+ chains. Your $100k effectively becomes $1M+ in delivered liquidity.

How Aqua0 Maximizes Your SLAC

We built our system to optimize for high SLAC:

1. Fast cross-chain coordination

Pull-execute-return cycle: ~10 seconds total
Capital is productive 90%+ of time
Minimizes "in transit" dead time

2. Smart routing

We track activity across all chains in real-time
Pull capital to where it's needed most
Avoid pulling when not necessary

3. Efficient return paths

Capital returns to "home" chain automatically
Ready for next pull immediately
No manual rebalancing needed

Result: 2-4x SLAC consistently, targeting 5-8x as we add chains.

SLAC vs Traditional Metrics

Here's how SLAC compares to other DeFi metrics:

TVL: Measures deposits (size) Volume: Measures activity (usage) APY: Measures returns (outcome) SLAC: Measures capital efficiency (productivity)

You can have:

High TVL, low SLAC (lots of idle capital)
High volume, low SLAC (concentrated on one chain)
High APY, low SLAC (small pool with lucky timing)

High SLAC = sustainable high APY across all conditions.

That's why it matters.

What SLAC Means for Your Returns

Simple math:

Traditional LP (SLAC 0.1x):

$300k deployed
10% utilization
5% APY
Annual earnings: $15k
ROI on deployed capital: 5%

Aqua0 LP (SLAC 2.5x):

$100k deployed
60% utilization (across 3 chains)
18% APY
Annual earnings: $18k
ROI on deployed capital: 18%

You deployed 1/3 the capital. Earned 20% more. That's 3.6x better capital efficiency.

That's what high SLAC delivers.
