Understand the project

Practical overview

When it fits

Use Dappkit when a JavaScript or TypeScript application needs documented code-level connection and contract interaction building blocks, including the illustrated ERC-20 workflows.

Who it is for

  • JavaScript and TypeScript developers building web3 applications.
  • Teams adding RPC connections or smart-contract interactions to a dApp.

Documented uses

  • Connect an application to an RPC endpoint and retrieve a wallet address.
  • Deploy an ERC-20 token contract and transfer tokens.
  • Read an ERC-20 token balance.
  • Use curated contract utilities as building blocks for dApp modules.
Before you choose

Requirements & limits

The repository documents npm installation and identifies the project as ISC-licensed open source.

  • The application needs an RPC endpoint URL for the documented connection flow.
  • The README distinguishes a user-authorized client connection from server-side read-only access.
  • The examples cover ERC-20 interactions; consult the SDK documentation and contract examples for other required utilities.
  • The repository lists Node.js, Next.js and Angular quick-start references.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Connect an application to an RPC endpoint and read an address

Use the documented Web3Connection example to connect to an RPC endpoint and retrieve an address.

Before you start

  • Dappkit installed in a JavaScript or TypeScript project.
  • An RPC endpoint URL.

Steps

  1. Create a Web3Connection with the web3Host set to the RPC endpoint URL.

  2. Call connect().

  3. Call getAddress() to retrieve the address.

Expected outcome

The example connects through the configured endpoint and reads an address.

Guide limitations

  • The example does not specify an endpoint provider or chain configuration.
  • For server-side read-only access, the README says a private key is not required; it shows a private-key option for other server-side use and warns not to share it.
