Extension that provides management functions for the DAO token

Extension that provides management functions for the DAO token
Last updated
The Token Owner extension (aibtc-token-owner) provides management functions for the DAO token, allowing the DAO to control token metadata and ownership through governance. This extension serves as the authorized interface between the DAO and its token contract, ensuring that token configuration changes can only be executed through proper governance channels.
Token URI Management: Updates the token's metadata URI through governance
Ownership Control: Allows the DAO to transfer token contract ownership
Permission Gating: Ensures only the DAO or authorized extensions can modify token settings
Contract Interoperability: Interfaces between the DAO and token contract using proper permissions
Contract Name
aibtc-token-owner
Version
1.0.0
Implements
extension, token-owner traits
Key Parameters
None (stateless extension)
The Token Owner extension acts as an authorized intermediary between the DAO and its token contract. When the DAO approves a proposal to update token settings, it calls the appropriate function on this extension. The extension verifies the caller is authorized (either the DAO itself or another approved extension), then uses as-contract to call the token contract with the proper permissions.
callbackPurpose: Standard extension callback function required by the extension trait
Parameters:
sender: principal - The principal that triggered the callback
memo: (buff 34) - Optional memo data
Returns: (response bool) - Returns true on success
Example:
set-token-uriPurpose: Updates the token's URI metadata, which controls how the token appears in wallets and explorers
Parameters:
value: (string-utf8 256) - The new URI string for the token metadata
Returns: (response bool) - Returns true on success or an error
Example:
This function can only be called by the DAO or an authorized extension. It updates the token's metadata URI, which typically points to a JSON file containing token information like name, symbol, description, and image.
transfer-ownershipPurpose: Transfers token contract ownership to a new principal
Parameters:
new-owner: principal - The principal that will become the new token contract owner
Returns: (response bool) - Returns true on success or an error
Example:
This function allows the DAO to transfer ownership of the token contract to a new principal, which could be useful during contract upgrades or governance changes.
is-dao-or-extensionPurpose: Internal authorization check to ensure only the DAO or authorized extensions can call sensitive functions
Parameters: None
Returns: (response bool) - Returns ok true if authorized, or err u7000 if unauthorized
u7000
ERR_UNAUTHORIZED
Caller is not the DAO or a valid extension
Ensure the function is called through proper DAO governance
Authorization Control: All management functions are protected by the is-dao-or-extension check, ensuring only authorized entities can modify token settings
Contract-Call Pattern: Uses the as-contract pattern to make calls to the token contract with the extension's authority
Governance Protection: Changes to token settings require going through the DAO's proposal and voting process
No Direct State: The extension maintains no state of its own, reducing attack surface
Limited Functionality: The extension provides only the minimum necessary functions for token management
