How to burn LP tokens to lock liquidity

Burning LP tokens permanently locks a pool's liquidity. Learn what that means, when to do it, and how to burn ERC-20 or LP tokens safely on Monad.

To burn LP tokens on Monad, open the Burn tool, connect the wallet that holds them, and pick your LP token in the selector — Monmint flags it as a liquidity-pool token. Set the amount (or tap Max), click Burn tokens, and sign. The LP tokens go to a dead address, locking that share of liquidity so no one can ever withdraw it.

Burning LP tokens is how a project proves its liquidity is locked. Liquidity-pool (LP) tokens are the receipt for your deposit — whoever holds them can pull the underlying liquidity back out. Send them to a dead address and that exit is gone for good: the liquidity stays in the pool and keeps trading, but nobody, the team included, can ever remove it.

It's irreversible, so burn only LP tokens you mean to lock forever, and only the portion you want locked. You'll need the wallet that holds the LP tokens, connected to Monad, plus a little MON for gas.

Walkthrough

Steps

  1. Open the Burn tool and connect

    Go to the Burn tool — “Take supply out of circulation” — and connect the wallet that holds your LP tokens. If you're on the wrong chain, click Switch to Monad first. The tool can burn any token; you'll point it at your LP token next.

  2. Select your LP token

    Open the token selector and choose your LP token. A Uniswap V2 LP shows as a pair like TOKEN / WMON with a “V2” badge; if it isn't listed, paste the LP token's contract address into the search. Once you pick it, Monmint flags it: “This appears to be a liquidity pool (LP) token.”

  3. Choose how much to lock

    Enter the amount of LP tokens to burn, or use the 25% / 50% / 75% / Max shortcuts — your balance shows as “You hold: …” on the right. You can lock the whole position or keep some back; only the portion you burn is locked.

  4. Burn and confirm

    Click Burn tokens and sign the single transaction — there's no approval step, since you're burning your own tokens. The LP tokens go to the dead address (0x…dEaD) and you get a “Burned … permanently” confirmation. The pool keeps trading; that liquidity simply can't be withdrawn anymore.

Used Uniswap V3? Your liquidity is a position NFT, not a fungible LP token — pick that position (it carries a “V3” badge and a fee tier) in the selector to burn it; pasting the pool address won't work. And if you'd rather get your assets back than lock them, don't burn — use Remove Liquidity to withdraw instead.

FAQ

Common questions

Does burning LP tokens remove the liquidity?
No — the liquidity stays in the pool and keeps trading. Burning the LP tokens just means no one can ever withdraw it, so it's locked rather than removed.
Can I undo a burn?
No. Burning is irreversible. Once the LP tokens are in a dead address they can't be recovered — so double-check the token and the amount before you sign.
How do I lock a Uniswap V3 position?
V3 liquidity isn't a fungible LP token — it's a position NFT in your wallet. In the Burn tool's selector, pick that position (it shows a “V3” badge and a fee tier) and burn it. Pasting the pool's address won't work, because your liquidity sits in the NFT, not the pool contract.
