Cover Image for Case Study: Chainlink MakerDAO


In the dynamic realm of Decentralized Finance (DeFi), MakerDAO plays a pivotal role as a decentralized stablecoin platform. This case study delves into the symbiotic integration between the Maker Keeper Network, as outlined in MIP63, and the Chainlink Automation Network.

Project Overview

The Keeper Network is a critical component of the MakerDAO ecosystem, responsible for maintaining the stability of the Dai stablecoin. The integration with Chainlink Automation Network is a strategic move to automate and further decentralize the essential functions of the Keeper Network, thereby enhancing the reliability and efficiency of the MakerDAO protocol.

Integration and Functionality

  • MakerDAO Job Sequencer contracts are integrated with Chainlink Automation contracts to automate the execution of essential protocol functions such as poking oracles, liquidating vaults, managing the autoline, managing D3Ms, etc.
  • MakerDAO Vesting contracts are integrated with Chainlink Automation Contracts to automate the payment of the fees to the Chainlink oracles, thereby achieving an autonomous and decentralized upkeep mechanism.
  • Chainlink Automation Network contracts are integrated to call the MakerDAO contracts to execute the necessary functions without human intervention.
  • Uniswap contracts are integrated to facilitate the exchange of Dai for LINK tokens, which are then used to pay the Chainlink oracles.

Development Process

HackBG tackled the architectural and developmental complexities of this project, emphasizing the establishment of a seamless integration linking the Maker Keeper Network with the Chainlink Automation Network. The process was characterized by the following key aspects:

  • Analysis and Design: The team conducted a comprehensive analysis of the MakerDAO protocol, the MIP63 proposal, and the Chainlink Automation Network to design a robust and efficient integration.

  • Smart Contract Development: The team developed and deployed contracts integrating seamlessly with the MakerDAO protocol, Chainlink Automation Network, and Uniswap.

  • Coordination with Chainlink and MakerDAO: The team collaborated closely with Chainlink and MakerDAO to ensure the seamless integration of the Keeper Network with the Chainlink Automation Network.

  • Testing and Deployment: The project underwent rigorous testing and auditing to ensure the reliability and security of the integration. The contracts were then deployed on the Ethereum mainnet.

  • Documentation and Community Engagement: The team documented the integration process and engaged with the community to foster awareness and understanding of the project’s significance.

  • Ongoing Maintenance and Monitoring: The team continues to maintain and monitor the integration, ensuring its continued operation.

User Benefits

End-users benefit from the transparent and automated execution of essential protocol functions. The integration with the Chainlink Automation Network fortifies the reliability of oracles, a cornerstone of MakerDAO’s decentralized ethos. This automated upkeep mechanism not only enhances efficiency but also minimizes the need for direct human involvement in routine tasks.

The Vision for the Project

The project envisions establishing a resilient and automated infrastructure for the Maker Keeper Network. By seamlessly integrating with Chainlink, it seeks to fortify the reliability of oracles, automate critical functions, and contribute to the overarching decentralization and efficiency of the MakerDAO protocol.

Technological Innovation and Impact

The integration of the Maker Keeper Network with the Chainlink Automation Network represents a significant technological innovation in the DeFi landscape. The project’s impact is multifaceted, as it contributes to the following key aspects:

  • Decentralization: The integration with Chainlink Automation Network enhances the decentralization of the Maker Keeper Network, thereby fortifying the protocol’s resilience and reliability.

  • Efficiency: By automating essential protocol functions, the project significantly enhances the efficiency of the MakerDAO protocol, reducing the need for manual intervention and streamlining the execution of critical tasks.

  • Reliability: The integration with Chainlink Automation Contracts fortifies the reliability of oracles, a crucial component of the MakerDAO ecosystem. This, in turn, contributes to the overall stability and trustworthiness of the protocol.

  • Strategic Collaboration: The project underscores the transformative potential of strategic collaborations in the DeFi space, highlighting the importance of integrating complementary technologies to achieve a more robust and efficient financial ecosystem.
