Install

The sequence.js SDK is composed of several sub-packages combined into a single meta-package called 0xsequence. To add the SDK to your project, add a dependency on 0xsequence to your package.json:

npm install 0xsequence ethers

or

pnpm install 0xsequence ethers

or

yarn add 0xsequence ethers

If you know that your project only requires specific sub-packages, you can also depend on those directly with npm add @0xsequence/<sub-package name>.

Your package.json should look something like this (actual version may vary):

{
  "name": "my-dapp",
  ...
  "dependencies": {
    "0xsequence": "^1.0.0",
    "ethers": ^5.7.0"
    ...
  }
}

CDN distribution as native JS

Optionally, 0xsequence can be installed as a JS script source (UMD distribution) via:

<script src="https://cdn.ethers.io/lib/ethers-5.7.umd.min.js"></script>
<script src="https://unpkg.com/0xsequence@latest/dist/0xsequence.umd.min.js"></script>
