Lock vs burn liquidity: what you keep
Creators burn or lock LP to show buyers that their own wallet can no longer withdraw that liquidity. In the Solana LP burner, a burn (Raydium) and a lock (Raydium or Meteora) differ in what you hold afterwards and in the trading fees.
A burn destroys your Raydium LP tokens through the Solana Token Program. Nothing goes to a dead address. Your share of the liquidity stays in the pool for the other LP holders, and you can no longer withdraw it. You earn no trading fees from it afterwards, and you hold nothing from the burned share. A burn is permanent.
A lock keeps your share in the pool, and nobody can withdraw it. On Raydium, Burn and Earn moves your LP tokens or position NFT into Raydium's lock program, and you hold a Fee Key NFT afterwards. On Meteora DAMM v2, the position stays in your wallet with the share you chose locked. The trading fees stay yours to claim. A lock is permanent, with no end date.
Burning LP tokens does not change your own token's supply. Only the LP token supply drops.
