Begin by entering the quantity of tokens you intend to buy/sell, and the system will automatically calculate the corresponding amount of TEA tokens you will need to pay/receive. For a deeper understanding of bonding curves and their calculations, refer to [our wiki page on bonding curve calculation](https://github.com/tearust/teaproject/wiki/TApps-List#tapp-token-strategy)

In contrast to top-up/withdrawal operations that involve layer1 (Ethereum) and require time for confirmation, this transaction is conducted at layer2, providing swift execution in approximately 3 to 4 seconds. Note that, due to the delay in syncing up the hosting node state, you may observe changes in the account balance within the next 10 seconds.
