Reinvesting crvUSD revenue to support its growth.
Previously, Curve redistributed 100% of its revenues to veCRV holders. This project explores a new design where a percentage of crvUSD-generated revenues are reinvested to support the protocol's growth. veCRV holders still decide who's is allowed to receive the fees through governance.
A smart contract system for collecting and distributing fees from Curve's crvUSD controllers.
The Fee Splitter project introduces a new mechanism for distributing crvUSD-generated revenues. Instead of redistributing 100% of revenues to veCRV holders, this system allows for a portion of the fees to be shared with protocol-aligned voters and other strategic initiatives.
The main contract responsible for collecting fees from multiple crvUSD controllers and distributing them according to predefined weights.
Key features:
- Supports both fixed and dynamic weight receivers. Fixed weight receivers have a predetermined share of the fees, while dynamic weight receivers can adjust their share based on certain conditions.
- Allows for updating the list of receivers
- Owned by a designated address (likely DAO-controlled)
A helper module integrated into the FeeSplitter to efficiently claim fees from multiple controllers simultaneously.
Key features:
- Maintains a list of allowed controllers
- Can claim fees from all controllers or a specified subset
The project includes a comprehensive testing suite:
- Unit tests for individual contract functions
- Integration tests for full contract interactions
- Hypothesis-based stateful tests for more robust scenario coverage
-
Install dependencies:
poetry install forge install
-
Run tests:
pytest tests/unitary # unit tests forge t # integration test pytest tests/hypothesis # stateful/fuzz testing

For deployment scripts and interactions, see the
scripts/directory.
The contract has been audited by Chainsecurity, the report can be found here.
The scripts/deploy_fee_splitter.ipynb Jupyter notebook provides a step-by-step process for deploying the FeeSplitter contract and setting up the initial configuration.
This codebase used to be home to autobribe, a protocol that never saw the light of day. Its unfinished code can still be found here.
