Monad Remove Liquidity - Withdraw from DEX Pools

The 20lab Monad remove liquidity tool lets you withdraw your tokens and accumulated fees from any DEX pool on an EVM chain. It works directly with DEX router contracts, which means it functions even when the DEX frontend is down, geo-blocked, or no longer maintained.

Common use cases:

• Recovering liquidity from pools on DEXes with broken or shut-down frontends
• Exiting positions from old or migrated DEX versions
• Withdrawing from geo-blocked DEXes
• Managing ERC-20 liquidity without depending on any third-party interface

The tool supports UniswapV2 fork DEXes across all supported chains and Algebra-like DEXes on selected chains. It's the companion tool to the ERC-20 add liquidity tool for closing out positions you opened earlier.

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

1. Find your LP token address (from wallet history or the original transaction) - or just enter the base and quote token addresses and the tool will locate it
2. Connect the wallet holding the LP tokens
3. Select the chain and the DEX protocol (most are UniswapV2 forks)
4. Enter the amount to withdraw
5. Approve and confirm

The DEX's router contract handles the withdrawal regardless of whether their website still exists. Your funds aren't stuck - they're waiting for you to withdraw them through direct contract interaction.

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

This works because LP tokens are deterministic - the same base/quote/DEX combination always produces the same LP token address. The tool checks the on-chain factory contract and resolves the pool address without manual lookup.

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

• Base token - Your share of the project token (memecoin, utility token, etc.)
• Quote token - Your share of the paired asset (WETH, USDC, USDT, etc.)
• Accumulated fees - Your cut of every swap fee collected since deposit (typically 0.25-0.3% per trade)

The ratio reflects the current pool state, not your original deposit. If prices have moved, the split will differ from what you put in - this is impermanent loss (or gain) becoming realized.

Two factors affect your withdrawal amount:

• Price changes (impermanent loss/gain) - If the token price moved significantly, the AMM rebalanced the pool through trades. You receive the current pool ratio, not your deposit ratio.
• Trading fees earned - You earned a proportional share of every swap fee while providing liquidity

For volatile memecoins, expect significant differences. A 10x pump means you withdraw mostly the quote token and few base tokens. A 90% dump means mostly base tokens and little quote token. Fees usually offset some or all of impermanent loss in high-volume pools.

Yes - partial withdrawals are fully supported. You can specify any percentage from near 0% to 100% of your LP tokens. Remaining LP tokens stay in the pool earning fees, with no penalty or lockup for partial withdrawals.

Common partial-withdrawal strategies:

• Taking profits while maintaining market depth
• Gradually exiting a position to reduce price impact on the pool
• Rebalancing across multiple positions on different chains or DEXes

Many sophisticated LPs withdraw gradually rather than all at once, especially in high-volume pools where ongoing fees are significant.

Three things are required:

• LP tokens in your wallet - The LP tokens received when adding liquidity, still in your control (not burned, locked, or transferred)
• Native coin for gas - ETH, BNB, MATIC, AVAX, etc. depending on the chain
• Correct network - Connect 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) - this is by design for projects that publicly locked their liquidity.

Withdrawal costs are straightforward:

• Gas fee - One transaction, cost depends on chain and current gas prices
• LP token approval (if first time) - One-time approval for the router contract
• 20lab platform fee - Small service fee for using the tool
• No DEX withdrawal fee - UniswapV2 forks don't charge for removing liquidity

You receive 100% of your pool share minus only the gas and 20lab fees. The DEX doesn't take a cut on withdrawal.

Low-liquidity pools still work normally for withdrawals:

• Your share is guaranteed - You always receive your proportional share of whatever remains in the pool
• No slippage on removal - Unlike swaps, withdrawals don't suffer from low-liquidity slippage
• You may be the last LP - If you're withdrawing the entire remaining liquidity, the pool ends up at zero and becomes inactive until someone else deposits

This is one reason the tool is especially useful for old, mostly-empty pools - you can extract whatever's left even if the pool isn't worth using normally.
