Assets Module

A simple, secure module for dealing with fungible assets.

The Assets module provides functionality for asset management of fungible asset classes with a fixed supply, including:

To use it in your runtime, you need to implement the assets Config.

The supported dispatchable functions are documented in the Call enum.

Admin: An account ID uniquely privileged to be able to unfreeze (thaw) an account and it’s assets, as well as forcibly transfer a particular class of assets between arbitrary accounts and reduce the balance of a particular class of assets of arbitrary accounts.
Asset issuance/minting: The creation of a new asset, whose total supply will belong to the account that issues the asset. This is a privileged operation.
Asset transfer: The reduction of the balance of an asset of one account with the corresponding increase in the balance of another.
Asset destruction: The process of reduce the balance of an asset of one account. This is a privileged operation.
Fungible asset: An asset whose units are interchangeable.
Issuer: An account ID uniquely privileged to be able to mint a particular class of assets.
Freezer: An account ID uniquely privileged to be able to freeze an account from transferring a particular class of assets.
Freezing: Removing the possibility of an unpermissioned transfer of an asset from a particular account.
Non-fungible asset: An asset for which each unit has unique characteristics.
Owner: An account ID uniquely privileged to be able to destroy a particular asset class, or to set the Issuer, Freezer or Admin of that asset class.
Zombie: An account which has a balance of some assets in this noble, but no other footprint on-chain, in particular no account managed in the fabric_system noble.

The assets system in Tetcore is designed to make the following possible:

Issue a new assets in a permissioned or permissionless way, if permissionless, then with a deposit required.
Allow accounts to hold these assets without otherwise existing on-chain (zombies).
Move assets between accounts.
Update the asset’s total supply.
Allow administrative activities by specially privileged accounts including freezing account balances and minting/burning assets.

destroy: Destroys an entire asset class; called by the asset class’s Owner.
mint: Increases the asset balance of an account; called by the asset class’s Issuer.
burn: Decreases the asset balance of an account; called by the asset class’s Admin.
force_transfer: Transfers between arbitrary accounts; called by the asset class’s Admin.
freeze: Disallows further transfers from an account; called by the asset class’s Freezer.
thaw: Allows further transfers from an account; called by the asset class’s Admin.
transfer_ownership: Changes an asset class’s Owner; called by the asset class’s Owner.
set_team: Changes an asset class’s Admin, Freezer and Issuer; called by the asset class’s Owner.
