# Simulated Mesh Trading

Since *SEN* can be enabled in all pools within Sentre protocol, all tokens will be exchanged through *SEN* if no direct pool is found. Therefore, the number of routes is always less than 2. We call it **Simulated Mesh Trading** due to the dependency on SEN. This property reminds us of Uniswap v1.
