Upgrading core modules

info

This page mentions many unimplemented features.

If you want to add or remove variables managed by Policy Contract or change existing specifications, you need to upgrade the core modules on Dev Protocol.

Smart contracts that upgraders should implement‚Äč

In order to upgrade the core modules, the developer needs to develop the following smart contracts.

1. Patch contracts‚Äč

Prepare smart contracts with patches applied to existing core modules or smart contracts that implement newly added modules.

2. Writer contract‚Äč

Prepare a smart contract to apply the patch.

A writer contract needs to be created as self-destructible contracts, as they are one-time contracts used for patching purposes.

The following interfaces are required for a writer contract.

write‚Äč

This function is called after the authority is temporarily transferred from the Upgrader Contract(unimplemented), and it is necessary to apply the patch with one call.

function write() external;

close‚Äč

Self-destruct. It would help if you verified that a caller is an Upgrader Contract(unimplemented).

function close() external;

Upgrader Contract‚Äč

A contract is responsible for managing the authority to upgrade the Dev Protocol core modules and enforcing core module upgrades passed by on-chain governance.

Upgrader Contract allows upgrade itself with a patch contract.
