ERC-1155 Tokenization Flow

After you deploy an ERC-1155 token project, token administrators and token owners follow a typical flow for creating tokens and completing lifecycle operations.

When you deploy a token project, the users in the list passed to the initialization method become token administrators of the chaincode. After deployment, the typical flow for creating tokens and completing lifecycle operations follows these steps:

Token administrator operations:

• Create user accounts for anyone who will possess tokens or complete token-related operations.
• For each user account, create token accounts. Users can have multiple fungible token accounts, but only one non-fungible token (NFT) account. Token administrators can use the createAccount method to create user and token accounts simultaneously instead of separately.
• Create fungible tokens, as needed. When you initialize a fungible token, you can assign the associated metadata and behaviors to the token.
• For fungible tokens, associate the fungible token accounts of users to specific fungible tokens.
• Add minter and burner roles to the token accounts of users as needed.

Token owner operations:

• Users who have the minter role for a specific token can create (mint) NFTs or fungible tokens.
• Users can transfer tokens between accounts, and check account balances.
• Users who have the burner role for a specific token can destroy (burn) NFTs or fungible tokens.

Vault manager operations:

• The user who has the vault role can lock NFTs. A locked NFT cannot be burned or transferred to other users.

The following diagram shows the overall process flow for an ERC-1155 tokenization scenario.

The following table summarizes the methods that are automatically generated when you scaffold an ERC-1155 token project.
