Inspiration

We were inspired by the MLH Web3Apps hackathon to take our first learning journey into the world of Web3, Blockchain, smart contracts and wallets ... To take our first peek under the hood of Web3 Infrastructure and see what we could build!

What it does (what we want it to do)

BlockTrade leverages the power of blockchain technology to provide a decentralized platform that allows individuals to trade fungible assets directly, without intermediaries. Through the use of smart contracts, BlockTrade ensures trustless and tamper-proof transactions.

With BlockTrade, users can access a wide range of fungible assets, including cryptocurrencies, tokens, and digital assets, all within a user-friendly interface. The platform offers a comprehensive suite of trading tools and features, empowering users to execute trades with ease and confidence.

BlockTrade enables lightning-fast transaction settlements, ensuring that users can capitalize on opportunities instantly. The platform prioritizes security, employing robust encryption protocols and multi-factor authentication to safeguard user funds and personal information.

How we built it

We installed the Hedera Hashgraph SDK and built an environment on the Hedera TestNet network. Following the tutorials in the Hedera documentation, we were able to create new accounts, create smart contracts, and transfer hbar.

We used ethers/ethereum to connect a Masknet wallet to both the Ethereum Mainnet and Hedera Testnet wallets via the JSON-RPC Hashio API. Connecting a users Masknet wallet to the Hedera Testnet wallet gave us access to the HASH SCAN dashboard where we could see the activity happening on the Hedera network in real time (learning opportunity).

We used Solidity to create a contract for our trading platform as well as a counter, and converted the Solidity code to bytecode.js so it could be utilized in Hedera.

We used React.js to build the Trading Pages of our app and included images of the fungible trades.

Challenges we ran into

We ran into many challenges as we simultaneously worked to understand Web3 dApps and deploy our project as we initially intended. We weren't able to create or deploy a contract on Hedera TestNet to initiate trades of physical assets.

We also struggled integrating images into our React app to display our concept of trading physical items. We did finally figure that out but our UI/UX suffered due to time constraints.

Accomplishments that we're proud of

We're proud of everything we learned this weekend, even the aspects of our application that we struggled with and those we couldn't get to work. We really stretched ourselves into unchartered, for us, the Web3 landscape!

Even though our BlockTrade application doesn't currently work, we are proud of the working components as well as our determination to learn and build a Web3 app this weekend.
