Hi bro,

I fixed all my mistakes for buying a token but, can't sell 🤒

Could you help ?

Hi @cem-altuner ,

I saw that the gas used by the transaction was 98%. Try increasing the gas limit from 460000 to 700000 for example. The BSC network is more busy in the last days. Also first try to sell manually on the site and then try to simulate the same transaction with code.
