How to Create ERC-404 Tokens Without Code

With Pandora_404’s recent surge you may want to understand what is the hype around ERC-404 about and perhaps create your own ERC-404 tokens.

First, let’s see what ERC-404 standard is:

You may not know this but $OS is actually the first token on the mainnet following the ERC-404 standard. They call these tokens Items. As per their documentation:

“Items are perfectly interoperable tokens on top of Ethereum. They can act as ERC20s, ERC1155s and as more advanced tokens with state of the art capabilities, while maintaining backward compatibility with all applications based on the ERC20 and ERC1155 standards.

There are three main types of Items:

  1. Native Items

  2. Wrapped Items (ERC20s, ERC721s, ERC1155s and ETH wrapped as Items)

  3. Deck Items (ERC721 and ERC1155 collections)

The infographic below compares the Item standard with the ERC20 and ERC1155 standards.”

Now onto how to create your own Items.

  • Head over to Ethereans Dapp.

  • Switch to the Optimism network (top right of the screen).

Create a Collection:

  • Select 'Items' from the left-hand menu.

  • Choose the "Create" tab at the top.

  • Under 'New Collection', click "Start".

  • Note: Creating an item collection is the first step, serving as a 'folder' for your tokens.

  • Enter the collection name and symbol.

  • Choose your Mint Host and Metadata Host, usually your personal wallet.

Setup Collection Metadata:

  • Complete the Metadata fields, ensuring the Description and Logo (a valid IPFS link) are included.

  • Tip: For IPFS uploads, use Pinata (link to IPFS upload tutorial).

  • Deploy the collection by signing the transaction.

Manage Collection:

  • Return to the 'Items' section and select "Manage Collections".

  • Locate your new collection either by searching or using the collection address.

Mint New Token:

  • In your collection, under host tools, select "New Item".

  • Fill in the metadata for your token: name, symbol, and supply.

  • Add a description, upload a cover image (token image) from an IPFS source, and complete other fields as needed.

  • After filling out all fields, click next and then submit.

  • Finalize by signing the transaction.

Congratulations! You have successfully created a new Token on the Optimism network. The tokens will be directly sent to the mint host's wallet.
