Locker & Beneficiary

Liquidity locking is handled entirely through Aerodrome's native Locker contracts. No third-party lock services.

How Locking Works

When the Launcher creates liquidity, the resulting LP position (ERC-20 token for vAMM, NFT for CL) is sent directly to Aerodrome's Locker contract with three parameters:

Parameter	Description
Lock duration	How long the LP is locked. Permanent locks use max.
Beneficiary	The address authorized to claim fees and rewards from the locked position.
Fee share	The platform fee split (15% to Reflect treasury, 85% to beneficiary).

The beneficiary cannot withdraw the LP. They can only claim the fees and rewards it generates.

V2 Locker vs CL Locker

Feature	V2 Locker	CL Locker
Launcher contract	..	..
LP type locked	ERC-20 LP token	NFT position (Non-Fungible Position Manager)
Gauge staking	stake() / unstake() on the Locker	Managed through the NFT position
Fee claiming	claimFees(recipient) returns Token0 + Token1	claimFees(recipient) returns Token0 + Token1
Reward claiming	claimRewards(recipient) returns AERO (when staked)	claimRewards(recipient) returns AERO (when staked)

Beneficiary System

The beneficiary address is the only wallet authorized to:

• Claim trading fees - accumulated swap fees in both pool tokens.

• Claim AERO rewards - emissions directed by veAERO voters (requires gauge staking).

• Stake / Unstake - move the locked LP into or out of an Aerodrome gauge.

• Transfer beneficiary - transfer the beneficiary role to another address.

The beneficiary is set at launch time and can be transferred later via transferBeneficiary() on the Locker contract.

Claiming Fees

Fees must be claimed from the unstaked position. If the LP is currently staked in a gauge:

1. Unstake from the gauge.

2. Claim fees (claimFees returns Token0 + Token1 amounts).

3. Re-stake into the gauge to continue earning AERO emissions.

AERO rewards can only be claimed while the position is staked in a gauge, and so graduate to a gauge first.
