This is a supporting repository for the Keeper project.

Normally, ETH transfers don't generate events you could search for or listen to, which is a problem if you want to monitor an address for incoming transfers. This repository holds the smart contract that proxies ETH payments for the Keeper service and generates appropriate events. The repository is also meant to be used as a dependency in other repositories.
This repo uses dotenv to load environment variables.
For development, and .env file should be created based on the .env.example template file. The .env file should never be commited.
In production, environment variables can be injected directly.
Below is a list of possible environment variables.
| Name | Type | Default | Description |
|---|---|---|---|
DEPLOYER_ADDRESS |
string |
Address of the deployer | |
DEPLOYER_PRIVATE_KEY |
string |
Private key of the deployer | |
ETHERSCAN_API_KEY |
string |
API key for Etherscan to automatically deploy contract source code via truffle-plugin-verify |
|
MAINNET_RPC_URL |

ROPSTEN_RPC_URL |

Run one of the following:
npm run deploy:devnpm run deploy:ropstennpm run deploy:mainnet
To deploy to the desired network.
After deployment, you may also run:
npm run verify:ropstennpm run verify:mainnet
To verify source code on Etherscan.
Run npm run build-release. This will compile the source code and switch to release branch. The compiled code can then be commited and tagged, e.g. v1.0.1.
Run npm run ganache:dev to start a local ganache instance.
Then you can do npm run deploy:dev to deploy to that instance to interact with the contract.
Tests are located in /test directory.
Run npm run ganache:test to start a local ganache instance for testing. Then run npm run test to execute the test suite.
