Restrictions

Since Opal is built on top of Tableland and NFT Storage, it is constrained by their individual protocol restrictions.

Collection Layer and Token Restrictions

Each table has a restriction on the number of rows and columns it can hold. Therefore, a collection may have no more than 500,000 layers or 500,000 tokens. Additionally, values in each cell must be no more than 1kb. Therefore, values such as name, description, trait_type, and value should be no more than 125 characters long.
