Atlas Modules
1. Introduction to Atlas Modules
Definition and Purpose of Atlas Modules
Atlas Modules are customizable smart contracts that define the specific rules, behaviors, and operational mechanics for DeFi applications built on the Atlas protocol. By leveraging a modular architecture, developers can tailor the execution context to meet the unique requirements and governance structures of their applications.
Key Purposes:
- Customization: Allow developers to define how transactions are processed, how revenue is allocated, how various roles interact within the protocol, and how hooks are implemented to validate, process, and execute transactions.
- Hook Implementation and Configuration: Developers can implement hook functions such as pre-operation, user operation, solver operation, and post-operation hooks, defining custom behaviors for each phase of a transaction.
- Flexibility: Enable the creation of diverse DeFi applications by providing a foundation that can be extended or modified without altering the core protocol.
- Interoperability: Facilitate seamless integration with different dApps, ensuring that each application can operate under its own set of rules while maintaining compatibility with the Atlas ecosystem.
How Modules Interact with the Atlas Protocol
Atlas Modules serve as the bridge between individual DeFi applications and the overarching Atlas protocol. They define the execution context, manage interactions between originators and solvers, and handle the allocation of value generated through Miner Extractable Value (MEV).
Interaction Flow:
- Module Deployment: Dapp Developers deploy their modules and reference Atlas Smart Contracts.
- Transaction Routing: DeFi applications route their transactions through the Atlas protocol, which references the appropriate module.
- Execution Context: The module dictates via hooks how transactions are validated, processed, and executed within the protocol.
- Value Distribution: MEV revenue is distributed according to the rules defined in the module (see Value Allocation).
Flexibility and Customization Options
Atlas Modules offer a high degree of flexibility, allowing developers to:
- Define Bid Valuation: Customize how solver bids are evaluated and ranked.
- Assign Roles: Specify who can act as Auctioneer and Bundler through various assignment mechanisms.
- Implement Hook Functions: Customize pre-operation, user operation, solver operation, and post-operation behaviors.
- Configure Execution Context: Tailor the environment in which operations are executed, including defining specific conditions and constraints.
- Integrate with dApps: Seamlessly wrap around different types of dApps, enabling a wide range of DeFi functionalities.

2. Core Components of Atlas Modules
Atlas Modules are composed of several core components that collectively define the behavior and rules of a DeFi application within the Atlas protocol. These components include Value Allocation and Auctioneer & Bundler Assignment, which provide essential functionalities that shape how the module interacts with the Atlas ecosystem.
2.1 Value Allocation
Explanation of MEV Revenue Distribution
Miner Extractable Value (MEV) represents the potential profit that can be extracted by searchers through strategies like back-running transactions within a block. In the Atlas protocol, MEV revenue is generated from the MEV opportunities identified and exploited by searchers, rather than from the efficiency of transaction execution or gas optimization.
MEV Revenue Distribution:
- Originators: The users or applications initiating transactions.
- Protocol Fees: A portion allocated to the Atlas protocol for maintenance and development.
The Value Allocation component determines how the MEV revenue is distributed among these parties, ensuring fair compensation and incentivizing participation.
Methods for Configuring Value Allocation
Developers can configure value allocation using various strategies, such as:
- Fixed Percentage Allocation: Predefined percentages assigned to originators and protocol fees.
- Dynamic Allocation: Adjusts distribution based on factors like transaction complexity or performance.
- Custom Logic: Implements bespoke algorithms to determine revenue distribution tailored to specific use cases.
Example Configuration Description:
An Atlas Module can specify that 95% of the MEV revenue goes to the originator and 5% to the protocol. Alternatively, the distribution percentages can be dynamic, adjusting based on other criteria defined by the developer.
2.2 Auctioneer & Bundler Assignment
Overview of Assignment Options
The Auctioneer and Bundler are critical roles within the Atlas protocol, responsible for managing the auction process and bundling transactions, respectively. Atlas Modules provide multiple options for assigning these roles, balancing control, decentralization, and automation.
| Assignment Option | Definition | Use Cases | Advantages | Disadvantages |
|---|---|---|---|---|
| Trusted Parties | Designates specific, trusted entities to act as Auctioneer and Bundler. | Controlled Environments, Security Concerns | Predictable behavior, easier troubleshooting | Centralization risks, potential single points of failure |
| Decentralized | Employs a decentralized mechanism, such as token-based voting, for role assignment. | Community Governance, Enhanced Security | Increased decentralization, greater resilience | Complexity in governance, slower decision-making |
| Dynamic Assignment | Roles assigned based on criteria or conditions, like stake size or performance metrics. | Performance-Based, Adaptive Systems | Encourages performance, adaptable to network | Complexity in criteria management, potential volatility |
| Smart Contract-based | Automates responsibilities through smart contracts, eliminating human actors. | Fully Decentralized, Impartial Operations | Complete automation, reduced operational costs | Limited flexibility, dependence on contract logic |
2.3 User Operation Validation
User Operation Validation ensures that incoming transactions (UserOps) meet the necessary criteria before being processed by the protocol. This component is responsible for verifying:
- Signature Validity: Ensures that the transaction is properly signed by the originator.
- Intent Verification: Confirms that the transaction aligns with the originator’s intent as defined in the module.
- Resource Availability: Checks that the originator has sufficient funds or permissions to execute the operation.
Proper validation mechanisms are crucial for maintaining the security and integrity of the protocol, preventing unauthorized or malicious transactions from being processed.
2.4 Solver Operation Validation and Sorting
Solver Operation Validation and Sorting involves evaluating the proposals submitted by solvers (SolverOps) and determining their suitability for execution.
Key Responsibilities:
- Validation: Ensures that SolverOps adhere to the rules and constraints defined in the module.
- Sorting: Ranks SolverOps based on predefined criteria such as bid value, efficiency, or reputation.
- Selection: Determines the optimal SolverOps to include in the final transaction bundle.
This component ensures that only the most suitable and efficient SolverOps are selected for execution, optimizing the overall performance and profitability of the protocol.
3. Customization Options
Atlas Modules provide various customization options, allowing developers to tailor the execution process to their specific needs. These options include configuring the execution context, defining pre-execution and post-execution logic, and more.
3.1 Execution Context Configuration
Execution Context Configuration involves setting up the environment in which operations are executed. This includes defining:
- State Variables: Variables that maintain the state of the application.
- Execution Parameters: Parameters that influence how operations are processed, such as gas limits or timeouts.
- Environmental Conditions: Conditions that must be met for operations to proceed, such as specific network states or external dependencies.
By configuring the execution context, developers can ensure that operations are executed under the desired conditions, enhancing both performance and security.
3.2 Pre-execution Logic
Pre-execution Logic consists of hook functions that are executed before the main operation. These hooks can perform tasks such as:
- Validation Checks: Ensuring prerequisites are met before execution.
- Setup Operations: Preparing necessary conditions or resources.
- Intent Definition: Specifying the originator’s intent for the operation.
Types of Pre-operation Hooks:
- Pre-operation Hooks: Executed before the main operation.
- User Operation Hooks: Define the core operation to be executed.
- Solver Operation Hooks: Define requirements and assistance for solvers.
These hooks allow developers to implement custom logic that runs prior to the main operation, ensuring that all necessary conditions are satisfied and that the operation aligns with the application's objectives.
3.3 Post-execution Processing
Post-execution Processing involves hook functions that are executed after the main operation and solver operations have been completed. These hooks can handle tasks such as:
- Cleanup Operations: Removing temporary data or resetting states.
- Bookkeeping: Recording the outcomes of operations.
- Value Distribution: Allocating MEV revenue according to predefined rules.
Post-execution hooks ensure that any necessary follow-up actions are performed, maintaining the application's integrity and facilitating accurate value distribution based on the module's configuration.
4. Integration with dApps
