Steps to Building a Web3 Multichain Dapp | According to Bard

Building a web3 multichain dapp from scratch can be a challenging but rewarding experience. To get started, here are some initial steps we can take:

1. Define the purpose and functionality of your dapp.

• What problem will your dapp solve?
• What features and functionalities will it offer?
• What user experience are you aiming for?
• Who is your target audience?

2. Choose the relevant blockchains.

• Which blockchains are best suited for your dapp’s needs?
• Consider factors like scalability, transaction fees, smart contract functionality, and existing ecosystem.
• Research existing multichain bridges and interoperability solutions.

3. Select the development tools and frameworks.

• Choose a frontend framework like React or Vue.js for building the user interface.
• Consider backend frameworks like Hardhat or Tendermint for interacting with smart contracts.
• Explore multichain development libraries and tools like Etherspot, Multichain SDK, or XCM.

4. Design and develop the smart contracts.

• Define the smart contract functionalities and logic.
• Choose a smart contract language like Solidity or Rust, depending on the chosen blockchain.
• Implement security best practices and secure coding principles.
• Test and audit the smart contracts before deployment.

5. Integrate the dapp with your chosen wallets and oracles.

• Enable users to connect their wallets and manage their assets within the dapp.
• Integrate oracles to access external data and trigger smart contract functionalities.

6. Deploy the dapp to the chosen blockchains.

• Configure the deployment process for each blockchain platform.
• Securely manage the deployment keys and private information.

7. Test and iterate.

• Thoroughly test the dapp across all supported blockchains and functionalities.
• Gather feedback from users and iterate on the design and features.
