# Flexibility to Add/Remove Token

With Smoothy's gas fee optimization, Smoothy is able to dynamically add or remove a token in the pool.  In contrast, Curve.fi currently supports up to 4 tokens in the pool, and to support new tokens, Curve.fi has to create new pools, which results in greater gas cost and lower liquidity.  Smoothy's dynamic token addition/removal feature brings great flexibility to support new tokens with extremely low gas cost.
