# Smart Contract and flowing of funds

In this page we describe how the Smart Contract controls and regulates the folowing funds between you and the player.
It is crucial that you read and understand the content of this page.

In DeBets there are two types of transaction:

• transactions that take place on the blockchain: these transactions happen anytime funds flow in and out of the Smart Contract during the life cycle of a player deposit. For instance, when a deposit is created the Smart Contract is invoked by the player wallet to inject funds into it. The injected funds represent the player balance for the newly created deposit. After the player has played some games, when the deposit is closed the Smart Contract is invoked again and, depending on the change in balance with respect to the amount initially deposited, the Smart Contract either sends the amount won to the player taking it from the balance of the corresponding gaming account or it adds the amount lost by the player to the corresponding gaming account.

• offchain transactions that takes place within DeBets Offchain Transaction Protocol: these transactions take place while games are being played each time the player balance changes as a result of betting or winning. In order not to impact the player experience it is crucial that such transactions introduce no delay and require no fee. This is made possible by DeBets Offchain Transaction Protocol. In this protocol a transaction is basically an agreement between the player and you on the balance change that occurs in a deposit after the player bets or wins. Such agreement consists in both parties (you and the player) to mutually sign a message that represents the balance change with their respective private keys. To know more about this mechanism and to understand the complete working of DeBets Offchain transaction protocol consult the user documentation.

This pages focuses on the transactions of the first type.
