dot-license-contracts

Part of Dotlicense. See that file for an overview of the project as well as the contract architecture.

Configuration

Create a .env file for each environment you intend to use. E.g create a file .env.rinkeby with the following key/value pairs:

# .env.rinkeby
KEY_MNEMONIC="cat dog frog tiger etc"
WALLET_PROVIDER_URL=https://rinkeby.infura.io/myapikeyhere

Use the NODE_ENV variable to designate a specific config file. E.g.:

NODE_ENV=rinkeby truffle migrate --network rinkeby

More configuration (such as gas limits and prices) can be found in truffle.js

In the Makefile there are commands such as:

make migrate-ropsten
make migrate-rinkeby

Note: you can use the --reset option to start your migrations from the beginning.

If you need to rebuild the ABI, you can do it with the following command:

# requires docker
make build-abi

This will generate a combined ABI that includes the abi, devdoc, and userdoc.

You can generate the gas estimates with the following command:

make gas-estimates

To submit your code to Etherscsan:

make flatten_source
cat LicenseCore.etherscan.sol | pbcopy
Visit the source verification page that supports the optimizer runs (Their "beta" page, at time of writing).
Use 200 in the number of optimization runs field (this is in truffle.js)
"Contract name" field should not have .sol at the end
You can find your compiler version by running: cat build/contracts/LicenseCore.json | jq -r '.compiler.version'
