# esLP

**esLP** ("escrowed LP") applies the esALB locking pattern to liquidity-pool tokens. The flagship esLP position is **esLP ALB-ETH** — a locked V2 LP token that earns boosted ALB rewards and protocol-fee yield, while remaining non-transferable.

> *Last updated: July 6, 2026.* esLP was introduced after esALB shipped (April 2024) and is referenced in the [Welcome page](/welcome-to-alien-base.md) and the AIP-2 fee-split structure.

## What esLP is

A non-transferable, lock-wrapped version of an LP token (currently ALB-ETH V2). The pattern is identical to esALB:

* Lock LP → esLP **1:1**.
* esLP earns higher emissions than the unlocked LP farm.
* esLP also receives a share of the **Real Yield** stream (WETH from protocol fees).
* Unlock paths mirror esALB: 100% after a 30-day cooldown (no penalty) or 1% instantly every 24 hours.

## Why use esLP

If you're providing the ALB-ETH liquidity that powers Alien Base's core market, esLP rewards you for committing to that role. It compresses the gap between "passive LP" and "long-term aligned holder" by giving committed LPs:

* A boost on top of the regular farm APR.
* A direct share of WETH Real Yield (the same stream that pays esALB stakers).
* Voting power on Snapshot proposals (esLP counts toward the esALB-equivalent voting strategy at a configured weight).

## How to lock

>

> The exact UI flow for esLP varies depending on whether the position lives in the legacy Farms tab or the new [Vaults](https://app.alienbase.xyz/vaults) page. Steps below describe the current Vaults flow.

1. Provide ALB-ETH liquidity on the [V2 pool](https://app.alienbase.xyz/swap) and receive your LP token.
2. Open the [Vaults](https://app.alienbase.xyz/vaults) page and find the **esLP ALB-ETH** vault.
3. Click **Lock** → choose the LP amount → approve the contract → confirm.
4. The LP token disappears from your wallet; an equivalent esLP balance appears in your portfolio.

To stake the esLP for boosted rewards, find the corresponding stake card in the same Vaults page, click **Stake**, and confirm.

## Unlocking

Same two paths as esALB:

* **100% in 30 days, no penalty.** The position enters a 30-day vesting state. You still farm at a 30% reduction during this window, then redeem within 7 days after the vest completes (or it re-locks).
* **1% every 24 hours, instant.** In the unstake modal, toggle "Instant 1% Redemption" → confirm.

You can mix the two paths as needed.

## Contracts

The esLP contracts on Base: `esLP-ALB-ETH` ("Infinite") at [`0x3d3a5ad6…8ea0`](https://basescan.org/address/0x3d3a5ad6d7beab234d7f0338a01e62b1d36d8ea0) and `esLP-B-ALB-ETH` ("Backstop") at [`0x4a023efe…6978`](https://basescan.org/address/0x4a023efe4b5cd304e800f29074186164fda36978). Both appear under **Vaults → Locked earn** in the dApp. ALB-WETH is currently the only pair with esLP positions.
