How to burn liquidswap lp tokens using their smart contract??

[ajaythxkur]

After adding tokens to pool, i want to completely burn the lp tokens received (doesn't mean remove liquidity)

How to burn a Coin in three ways

1. I have access to the BurnCapability

• I can burn them with 0x1::coin::burn if I have access to this. Likely you don't unless you created the LP token.

2. I'm a programmer and I want to lock it in a vault and throw away the key

• I can write a simple immutable contract that works as a vault

module addr::vault {
  use aptos_framework::coin;
  struct Vault<MyCoin> {
      coins: Coin<MyCoin>
  }

  entry fun lock_forever<MyCoin>(caller: &signer, amount: u64) {
     let coins = coin::withdraw<MyCoin>(caller, amount);
     move_to(caller, Vault<MyCoin>{
         coins
     });
  }
}

3. Transfer them to an address that no one can access

This is most used in the community for things that don't apply to number 1

Just transfer to a burn address (usually used on Aptos as 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF).
