This is a subscription-based circuit breaker system leveraging the power of Chainlink. The system monitors specific Chainlink price feeds for fluctuations beyond a user-defined threshold. Upon reaching this threshold, it performs a pre-set action, all in a decentralized and automated manner.
The Factory design pattern is used to create user-specific Circuit Breaker contracts, and Chainlink Upkeeps ensure the system operates continuously. Moreover, the system includes a unique method for swapping LINK tokens from ERC-20 to ERC-677 standards to fund upkeep operations.
