Concentrated Liquidity (V3)

Concentrated liquidity on Alien Base

Alien Base V3 implements Uniswap V3-style concentrated liquidity: instead of spreading your capital across the whole price curve, you pick a price range and concentrate your liquidity there. The result is much higher capital efficiency at the cost of being out-of-range when price moves outside your bounds.

Fee tiers

Alien Base V3 supports seven fee tiers. The right choice depends on the volatility of the pair:

Fee

Best for

0.01%

Tightly-pegged stablecoin pairs (USDC/USDbC, USDC/USDT)

0.02%

Standard stablecoin pairs

0.03%

LSTs and very-blue-chip volatile pairs (ETH/cbETH)

0.04%

Wider-spread stable / LSD pairs

0.075%

Blue chips (ETH, BTC and wrapped variants)

0.30%

Mid-cap and standard tokens

1.00%

Small-cap and memecoin pairs

Each pool collects its tier on every swap. Pool fees are split 50% to LPs / 50% to esALB stakers as Real Yield (paid in WETH and the underlying tokens). Full breakdown: Fees.

How concentrated liquidity works

Each LP position has a lower price and an upper price.
While the market price is inside the range, the position earns trading fees and oscillates between the two assets.
While outside the range, the position holds 100% of one asset and earns no fees.

A narrower range = more fees per dollar when in range, more frequent re-balancing needed. A wider range = fewer fees per dollar but less attention required.

Choose ranges that match your view of where the asset will trade.

Two ways to provide V3 liquidity

Option A — Vaults (Bunni-wrapped, recommended for most users)

Use the Vaults page. Pick a pre-configured strategy (Wide / Narrow / Ultra Narrow / Classic V3), deposit, and earn pool fees + ALB rewards. The position is wrapped as an ERC-20 share by Bunni, which means:

No NFT to manage.
Composable — can be staked, locked, or used elsewhere.
One-click Zap-in from any asset.

Range bounds are managed at the Vault level. When a Vault gets close to its bounds, a new Vault with refreshed bounds is deployed.

Option B — Manual V3 (full control)

Click New position on the Vaults or Dashboard page. Pick V2 or V3 with the selector, choose your pair, fee tier, lower price, and upper price. The V3 position is created as a Uniswap-style NFT. You can:

Choose any range you want.
Add or remove liquidity at will.
Collect fees independently.
Re-balance manually as the market moves.

The trade-off: you get full flexibility but the position is not automatically eligible for ALB farm rewards (those are paid on Bunni-wrapped Vaults), and you have to actively manage the range.

When out-of-range happens

If price exits your range:

Your position holds 100% of whichever asset is on the "wrong" side.
You stop earning fees.
You're effectively long the asset (or paid in the asset) at your range boundary.

To re-engage, either:

Wait for price to come back into range, or
Withdraw and re-deposit into a new range.

For Bunni Vaults, the protocol manages this at the Vault level: if a Vault drifts toward its boundary, a fresh Vault is launched. You can migrate when convenient — but no automatic migration happens. (That's exactly the gap Mothership is designed to fill, with active strategies that re-balance on your behalf.)
