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	On-chain governance	Predefined actions, faster voting, veto, rewards
DAO Charter	Mission and values	On-chain organizational constitution
DAO Epoch	Time tracking	Bitcoin block-based epochs, configurable length
DAO Users	User management	User registration, reputation tracking
Onchain Messaging	Communication	Verified DAO/user messages, permanent records via print events
Rewards Account	Reward disbursement	Securely holds and transfers SIP-010 token rewards
Token Owner	Token management	DAO Token URI updates, ownership controls
Treasury	FT Asset management	Fungible token (SIP-010) support, controlled access

Adding New Extensions

The first cohort of AIBTC DAOs will not have the ability to add new extensions or modify the operation of the DAO. This scope is intentional to refine the voting and reward mechanisms.

Future iterations of AIBTC DAOs can implement an extension that allows for this and other features.

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
