Universal Accounts within UniversalX

​
What is the Universal SDK?

Universal Accounts give your users a single account and balance across all supported chains. The Universal Accounts SDK allows you to integrate Universal Accounts into your dApp. This enables you to onboard users from any ecosystem without requiring them to bridge, regardless of where your dApp is deployed.

​
Integration Flow

The Universal Accounts SDK makes it simple to integrate chain abstraction into your app with minimal code changes. Every transaction is routed through Particle’s Chain Abstraction layer, so balances and gas are handled across chains automatically.

​
Steps to integrate

  1. Initialize the Universal Account with a single config object.
  2. Construct and execute transactions using the SDK.
  3. Sign with your existing provider (e.g. RainbowKit, Particle Auth, or any wallet connector).
That’s it—your current execution flow stays the same. No additional bridging or gas logic required.
The SDK treats the user’s Primary Assets as a unified balance across all supported chains.

​
What you get out of the box

  • Read balances across chains as if they were one.
  • Send transactions without adding bridging logic.
  • Gas abstraction automatically handled—no extra code required.
Universal Accounts are independent smart accounts, not extensions of an existing wallet.
  • When a user creates a Universal Account with their existing wallet, their assets stay in the original wallet. Nothing is moved automatically.
  • Users can transfer assets into their Universal Account from any supported chain through in-app flows.
  • As a developer, you can choose whether to make Universal Accounts the default experience or keep them as an optional toggle alongside EOAs.
