It is a simpler version of swap exchange that is available on the Binance Smart Chain network. It is currently not fully operational as many of the options have been eliminated.
The recommendation is not to use this exchange since it is discontinued, in the same way there is another that seems to supplant this and was in development but like BSCSWAp many of the options of market analysis or liquidity verification are not available or contracts. So it could have bugs or errors in the programming code.
In general there is no official data since November 17 in your accounts and official media, You should not use this service as your funds may be at risk.
