DAO Extensions

Overview of the DAO extension system

Extensions are modular components that provide specific functionality to the DAO. They allow the DAO to be customized and expanded without modifying the core contract.

How Extensions Work

Each extension:

• Implements the extension trait

• Can be enabled or disabled by the DAO

• Has specific permissions and capabilities

• Interacts with the DAO through a standardized interface

Extension Architecture

Extensions follow a consistent pattern:

1. Trait Implementation: Each extension implements both the base extension trait and its own specialized trait

2. Callback Function: All extensions have a standard callback function for DAO communication

3. Permission Checks: Extensions verify that calls come from authorized sources

4. Event Logging: Extensions emit events for important actions

5. Error Handling: Extensions use standardized error codes

Available Extensions

Extension	Purpose	Key Features
Action Proposals	Lower-threshold governance	Predefined actions, faster voting
Bank Account	Operational fund management	Periodic withdrawals, controlled spending
Core Proposals	High-threshold governance	Arbitrary code execution, high security
DAO Charter	Mission and values	On-chain organizational constitution
Onchain Messaging	Communication	Verified DAO messages, permanent records
Payments/Invoices	Revenue generation	Service payments, resource management
Token Owner	Token management	URI updates, ownership controls
Treasury	Asset management	Multi-asset support, controlled access

Adding New Extensions

New extensions can be added to the DAO through core proposals. To create a new extension:

1. Implement the extension trait

2. Implement any specialized traits needed

3. Follow the standard extension pattern

4. Submit as a core proposal for DAO approval

Extension Security

Extensions follow these security principles:

• Only the DAO can enable/disable extensions

• Extensions verify caller permissions

• Critical operations require DAO approval

• Extensions use standardized error handling

• Extensions emit events for all important actions
