Token Management

The extension provides two key management functions:

1. Token URI Management:

   • Updates the token's URI metadata

   • Controls how the token appears in wallets and explorers

   • Can point to decentralized storage for token information

2. Ownership Transfer:

   • Allows the DAO to transfer token contract ownership

   • Provides flexibility for contract upgrades or governance changes

   • Executed through DAO proposals for security

Security Features

• All functions can only be called by the DAO or authorized extensions

• Changes require proposal approval through governance

• The extension uses the contract-call? pattern to execute functions with proper permissions
