opium-protocol-v2 VS truffle

The struct above is the schema that we use in the Opium Protocol. Let’s quickly walk through it: uint256 margin: aka the reference collateral that is (usually) parsed by the IDerivativeLogic SyntheticId getMargin function to set the collateral requirements of the option contract. uint256 endTime: aka the maturity date of the contract. It is the point in time at which the buyers will have the right to exercise their contract. uint256[] params: option contracts can differ greatly in the complexity of their financial requirements, as such Opium uses a dynamic array to ensure a high degree of flexibility to the consumers of the protocol, as to enable them to encode arbitrary parameters in their LibDerivative asset definition if needed. One convention to keep in mind is that, however, the first item of the params array is always expected to be the strike price. The strike price is the value that determines the profitability of an option upon expiry: if the market price is above the strike price in case of a call option or the market price is below the strike price in the context of a put option, the option is said to be ‘in the money’ and the buyer stands to make a profit. Vice-versa, the option is said to be out of the money and the buyer stands to lose the premium or the collateral that they had to exchange for the ownership of the option contract. oracleId: oracles are the entities that inform the Opium Protocol about the value of an asset upon its maturity date. The Opium Protocol does not enforce any specification as for what can be used as an oracle, be it on-chain or off-chain. token: the address of the ERC20 token to be used as a collateral syntheticId: the address of the contract where the financial logic of the derivative is encoded. The Opium Protocol expects the syntheticId contracts to be compliant with the specifications of the IDerivativeLogic interface.

Truffle

You’ve probably heard that Generative AI has demonstrated the potential to disrupt a huge number of industries and jobs — and web3 is no exception. But how well can ChatGPT create smart contracts? Can using ChatGPT to code smart contracts make you a 10x developer? In this article, we’ll try it out and see. We’ll walk through writing and deploying an Ethereum smart contract using MetaMask, Infura, and Truffle … and we will ask ChatGPT for instructions on how to do everything from the code to the deployment.

truffle v5.8.3 and v5.8.4 — update Ganache to the most recent version which supports Shanghai and small fixes

For example, I used the Truffle Suite to write, compile, and deploy my first smart contracts, which includes Ganache to create a local blockchain and Drizzle to create a front-end dapp interface.

truffle v5.8.0 - Truffle introduces the Truffle Dashboard Hardhat plugin, which allows developers to see decoded transaction information when using Truffle Dashboard with their Hardhat projects.

In this article, we’ll explore what makes Linea so exciting. Then, we’ll walk through a tutorial on how to build a dapp on the Linea testnet. Finally, we’ll create our own cryptocurrency on Linea using Solidity, MetaMask, and Truffle: all mature ecosystem tools that are used by blockchain developers to build dapps.

Truffle is a popular development and testing framework for dApps, both for first time and experienced Ethereum developers. As well as containing a web3.js library, Truffle is simple, user friendly and, with over 56K GitHub users, trusted. To install Truffle you need to have Node, NPM and Python. You can install Truffle via NPM with the command ‘npm install -g truffle.’

The inspiration for the article came from a project I had built a little over a month earlier, for which I wrote a different article. In this initial project, I was actually using a Hardhat local node for my smart contract development. I decided to switch to Truffle for the final article, because it had a more intuitive demo contract, and because the command line tool made it easier to create manual transactions.

Easy for devs — The zkEVM supports most popular tools out of the box. You can build, test, debug, and deploy your smart contracts with Hardhat, Infura, Truffle, etc. All the tools you use now, you can keep using. And there is already a bridge to move tokens onto and off the network.
