Abstraction Engine

The Abstraction Engine of the Yggdrasil Protocol introduces an advanced layer of account abstraction designed to enhance transaction flexibility and efficiency across blockchain networks. The engine has three main components: Paymaster, UserOperation, and Bundlers. The Paymaster abstracts transaction gas fees by allowing users to pay with any ERC20/CW20 token and employing a "pre-charge and later refund" model to streamline fee management. UserOperation provides a higher-level interface for initiating complex transactions, such as batching multiple operations and delegating fees, enhancing usability and flexibility. Bundlers collect and consolidate multiple UserOperations into a single on-chain submission, improving system efficiency and reducing costs. Together, these components of the Abstraction Engine makes the transactions smoother and more efficient across the Yggdrasil Protocol network.
