# Income sources
## House edge
Games will provide Solaris Betting with crypto revenues due to the games house edge, like a regular gambling venture.
**Initially, the house edge is 3% on all won games for MATIC, BNB and AVAX, and 2.5% for $SBT.** It is taken from the total won bet payout: bet amount + profit. Note that a share of the house edge will be distributed to stackers and to reffers.
## Bank overflow
To have a higher payout and an incremental growth of the platform at the same time, the bank's smart contract dynamically sustains the tokens' balances.
When the defined bank overflow threshold amount is reached on a token balance, the bank sends a percentage to the treasury, and the new token's balance reference is set.
* The bank overflow threshold is initially set up at *1%* of the initial token's balance.
* The percentage of the threshold send to the treasury is initially *25%* of the overflow, and **25%** to the team. Therefore, 50% of the balance overflow remains in the token's balance.
