DCA.Monster is an Automated Market Maker (AMM) leveraging ERC20 streams for granular, efficient on-chain Dollar Cost Averaging (DCA). The project utilizes Cartesi rollups by leveraging its capability to handle thousands of streams, enabling efficient off-chain computation of balances for users, the AMM, and liquidity pools. This approach allows for seamless implementation of Dollar Cost Averaging with infinite granularity, which would be impractical within the constraints of an EVM smart contract due to the extensive computation required.
