We Made a DeFi DApp - Open Beta on the Ropsten Testnet!

Hello r/ethereum!

We are Nick and Chris, two long-term ETH HODLers and software developers who want to help build useful DeFi DApps. That's why we created https://diffex.io, a smart contract DApp that allows you to write, sell, buy, and execute options contracts for ERC20 tokens. Currently, we have launched a beta version of the Dapp on the Ropsten testnet that you can try without using any real ETH or ERC20 tokens. For this beta version, we created a free ERC20 token called DFTX (DiffEx Test) that can be used as the underlying asset for calls and puts. To get some, join our discord server: https://discord.gg/fZksGrs89W or telegram: https://t.me/diffexio. If you have any questions or comments, please feel free to leave them here or on the r/diffexio subreddit!

Take a look at our whitepaper:
