Base Remove Liquidity

The Base remove liquidity tool enables you to withdraw your tokens and accumulated fees from DEX liquidity pools. Common use cases include:

• Recovering funds from pools on DEXes with not working or inaccessible frontends
• Exiting liquidity positions from old or migrated pools
• Withdrawing from pools on DEXes that have been geo-blocked in your region
• Managing Base liquidity without depending on any third-party interface

The tool works with UniswapV2 fork DEXes across all supported chains, with Algebra-like DEX support on selected chains. If the pool exists on-chain and you have corresponding LP tokens, you can withdraw your liquidity from it.

DEX frontends come and go, but smart contracts live forever on the blockchain. To recover your liquidity:

1. Find your LP token address from your wallet history or the original transaction
2. Connect the wallet holding the LP tokens to 20lab
3. Select the correct chain and the DEX protocol (most are UniswapV2 forks)
4. Enter the LP token address and amount to withdraw
5. Approve and confirm the removal transaction

The DEX's router contract handles the withdrawal regardless of whether their website exists. Your funds aren't stuck - they're just waiting for you to use 20lab Base remove liquidity tool to withdraw your liquidity from the contract directly!

You don't need to find it manually. Simply enter the base token and quote token addresses in the 20lab Base remove liquidity tool interface, select the DEX, and the tool will automatically locate the corresponding pool and LP token for you.

You receive your proportional share of both tokens currently in the pool:

• Base Token - Your share of the token (memecoin, utility token, etc.)
• Quote Token - Your share of the paired asset (WETH, USDC, USDT, etc.)
• Accumulated Fees - Your cut of all swap fees collected since deposit

The ratio you receive reflects the current pool state, not your original deposit. Price movements since you added liquidity determine the final split - this is the nature of AMM liquidity provision.

Two factors affect your final withdrawal:

• Price Changes - If the Base token price moved significantly, the pool rebalanced through trades
• Trading Fees - You earned a share of every swap (typically 0.25-0.3% per trade)

For volatile memecoins, expect significant differences. A 10x pump means you'll withdraw mostly ETH and few tokens. A 90% dump means you'll get back mostly tokens and little ETH.

Yes, partial withdrawals are fully supported:

• Specify any percentage from near 0% to 100% of your Base LP tokens balance
• Remaining Base LP tokens stay in the pool earning fees
• No penalty or lockup for partial withdrawals
• Useful for taking profits while maintaining market depth

Many liquidity providers gradually exit positions rather than withdrawing everything at once, especially if the pool has significant trading volume generating ongoing fees.

You need three things:

• LP Tokens in Your Wallet - The Base LP tokens you received when adding liquidity (not burned or locked)
• Native Token for Gas - ETH, BNB, POL, etc. depending on the chain
• Correct Network - Must be connected to the same chain where the pool exists

If your LP tokens were sent to a locker contract or burned to a dead address, that liquidity is permanently inaccessible until the lock expires (if ever).

Withdrawal costs are straightforward:

• Gas Fee - Transactions cost, varies by network and its congestion
• Approval (if needed) - One-time LP token approval for the router contract
• Platform Fee - 20lab's service fee

No percentage is taken from your withdrawn tokens by the DEX - you receive 100% of your pool share.

Low liquidity pools still function normally for withdrawals:

• Your Share is Guaranteed - You always receive your proportional share of whatever remains
• No Slippage on Removal - Unlike swaps, removals don't suffer from low liquidity slippage
• Pool May Become Inactive - After large withdrawals, remaining liquidity may be too low for practical trading

Even if you're the last liquidity provider, you can withdraw everything. The pool contract will still exist but with zero liquidity - no one can trade until someone adds liquidity again.
