|
|
|
|
1. Fork and clone it
|
|
2. Create a feature branch: `git checkout -b new-connector`
|
|
3. Add the connector solidity file to `contracts/connectors`
|
|
4. Commit changes: `git commit -am 'Added a connector'`
|
|
5. Push to the remote branch: `git push origin new-connector`
|
|
6. Create a new Pull Request.
|
|
|
|
## Requirements
|
|
|
|
Be sure to comply with the requirements while building connectors for better compatibility.
|
|
|
|
- Import common files from `contracts/common` directory.
|
|
- The contracts should not have `selfdestruct()`.
|
|
- The contracts should not have `delegatecall()`.
|
|
- Use `uint(-1)` for maximum amount everywhere.
|
|
- Use `getEthAddr()` to denote Ethereum (non-ERC20).
|
|
- Use `address(this)` instead of `msg.sender` for fetching balance on-chain, etc.
|
|
- Only `approve()` limited amount while giving ERC20 allowance, which strictly needs to be 0 by the end of the spell.
|
|
- Use `getId()` for getting value that saved from previous spell.
|
|
- Use `setId()` for setting value to save for the future spell.
|
|
|
|
<!-- - If required, Add two additional parameter, `getId` & `setId` in external public functions.
|
|
- Use `getUint()` or `setUint()` functions to fetch or store values.
|
|
- Call `emitEvent()` after every external public functions. -->
|
|
|
|
<!-- Be sure to check [this mock file](https://github.com/InstaDApp/dsa-connectors/blob/master/contracts/connectors/mock.sol) for reference. -->
