DeFi derivative development: from zero to hero with Opium v2 pt.1
One of the design choices that was scrapped was the usage of Opium’s very own token standard ERC 721o - a custom flavor of the more notorious ERC721- whose purpose was to allow for the creation of non-fungible derivative portfolios. Nowadays a similar rationale has been implemented by the ERC1155 standard, however the degree of interoperability and easy-to-reason-about clean API that the good-old-fashioned ERC20 provides are simply undefeated. As such, following a long-existing DeFi trend that was first popularized by Uniswap, Opium makes use of a factory pattern that mints ERC20 tokens in a measure proportional to the ownership of LONG/SHORT option positions of their respective owners. However, as the scope of the article is to give enough of a rundown for a developer to get their feet wet with Opium v2, we will postpone a deep dive into the Opium Protocol architecture to a later date. If you have any questions, feel free to drop by on the governance forum!
