# ASX

The ASX contract is a governance ERC-20 token with a total supply of 100000000 tokens. The whole supply is minted in time of deployment and the owner of tokens decides how to distribute them. The idea is to distribute them in the following way: 50% - for the staking rewards, 25% - to the team, 25% - to the treasury.

Tokens for the staking rewards are distributed on the StakePrizePool contract as the rewards for the stETH staking.
