## Oracle helper contract
|
||||
|
||||
Oracle helper contract NEF and manifest files are generated automatically by
|
||||
`TestGenerateOracleContract` and are used in tests. Do not modify these files manually.
|
||||
To regenerate these files:
|
||||
|
||||
1. Open `TestGenerateOracleContract` and set `saveState` flag to `true`.
|
||||
2. Run `TestGenerateOracleContract`.
|
||||
3. Set `saveState` back to `false`.
