 ### Withdraw liquidity
 
 To withdraw liquidity, burning LP tokens is required. You can refer to examples of Jetton burning in the [respective section of Jettons Cookbook page](/cookbook/jettons#burning-jetton).
-
+However more TONs than for the usual burn should be attached. Too small number of attached tons may cause LP tokens to be burned, but liquidity from the pool will not be sent (or will be sent partially).
+So anyone should consider to attach at least 0.5 TON. Excesses will be returned.
