What’s the best way to handle access control in Move?
Q: Solidity uses modifiers like onlyOwner, but Move’s capability-based model feels more powerful. How do you design capability-based access control in practice?
- Sui
In Move, access control is best handled using capabilities—special resources that grant permission to perform actions. Instead of Solidity’s modifiers, you give functions access only if the caller holds the right capability resource. This method allows precise and flexible permission control. For more info, visit [https://docs.move.dev/resources/capabilities](https://docs.move.dev/resources/capabilities) Example: ```move module AccessControl { resource struct AdminCapability {} public fun create_admin_capability(account: &signer): AdminCapability { AdminCapability {} } public fun restricted_action(admin: &AdminCapability) { // only callable by capability holder } } ``` This ensures only authorized users can run restricted functions.
