No-loss gaming dapps on Evmos
Winmos is a no loss lottery hosted on Evmos Testnet that gathers user staking rewards and picks 1 winner every 24 hours.
Winmos is a no loss lottery implementation on Evmos utilizing EVM extensions to stake and distribute rewards. It utilizes the contract balance to ensure on-chain funds are locked so the lottery has a fair winner each time inflation rewards are distributed.
The addition of
Distribution.sol allow for smart contracts to
execute Cosmos transactions without leaving the EVM environment. This allows Winmos to
onboard new users to the EVM and Evmos by providing a no loss lottery system similar to
PoolTogether on Ethereum.
After watching the workshops and reviewing the example code from the extensions repo Winmos expanded the concept by creating a fully automated client, winner selection and withdrawing systems. Users can safely deposit and withdraw from the contract as well as enter and exit the lottery all through EVM transaction that ensure their funds are tracked by the contract state. A winner is picked based on the number of EVMOS they have staked ensuring higher odds to users that have pledged more. A random number to shuffle participants and pick a winning range is generated using the DIAOracle
The maximum of 7 unbonding delegations that is allowed on the Cosmos SDK could limit how often users can make small undelegations.
Ethereum allows for depositing into a contract and using that same balance in a follow-up
operation. This doesn't work on Evmos so an additional
Deposit transaction is required.
