Deploying on Rinkeby and Mainnet
To deploy on Rinkeby and Mainnet, make sure to specify your Infura project ID and mnemonic in the
.env file. Alternatively, you can change
truffle-config.js to use other provider of your choice.
Contract may be customized via ENV variables:
|ENV variable||Description||Default value|
|PROPOSAL_TIME||Governance proposal cool-off time (in seconds)||
|EXIT_STAKE||Exit stake (in Wei)||100000000000000000|
|EXIT_DURATION||Exit duration (in seconds)||
|DEPLOYED_TOKEN||Token to be configured in vault|
|EPOCH_LENGTH||Number of initial slots for validators||2|
|PARENT_BLOCK_INTERVAL||Number of Ethereum blocks between Plasma periods||2|
|TAX_RATE||Initial tax rate (0 - 1000 equals 0% - 100%)||50|
|POA_REWARD||Reward rate before supply of 7 million reached||778000000000000000000|
|GOV_OWNER||Owner address of the
PROPOSAL_TIME=600 EXIT_DURATION=180 yarn deploy deploys plasma contract with 3 minutes exit duration governed by MinGov with 10 minutes proposal time.
This will deploy deploy token, plasma and governance contracts.
Deploy only plasma and governance contracts (reusing token)
Good things to know

In this repository are the solidity smart contracts implementing LeapDAO's plasma leap.
There are 3 smart contracts that get deployed:
The bridge is responsible for storing the period chain. It is the source of truth for the plasma chain.
The operator is the contract that is responsible for submitting new periods to the bridge.
This contract is responsible for user funds. Explained in more detail below.
The ExitHandler is actually the final contract in an inheritance chain that goes as follows:
The vault defines what types of assets are allowed on the plasma chain and is responsible for registration of these assets.
The deposit handler is in general responsible for how funds get onto the plasma chain.
The exit handler is in general responsible for how funds leave the plasma chain.
