The Universal SDK Is Now Public! Get Building Chain-Agnostic Apps Today

Web3 keeps multiplying and fragmenting. 2x the chains. 4x the bridges. Infinite times more capital flying across chains.

Your time to build, however, isn’t growing as fast. 

While every new chain means another address format, token standard, gas-payment flow, and bridge integration to code, test, and maintain, your team cannot possibly keep up. 

BUT.

Chain abstraction fixes this.

Universal Accounts allow you to give your users a single smart account and balance that works across every supported chain (EVM + Solana!) The new Universal SDKs let you tap into this power, inheriting the battle-tested infra that already powers UniversalX… and build retail-ready projects from the get-go.

How Universal Accounts actually work (and where they already work)

Behind the scenes, Universal Accounts aggregate your users’ tokens across chains, allow them to interact across all supported chains, and even simplify gas for them based on their balance. No bridge clicks required.

This system relies on a network of smart accounts simultaneously living on every supported chain. All of this is coordinated by Particle Network’s L1 blockchain.

The result? One account, one balance, any chain.

Universal Accounts are live on:

• Twelve EVM networks—Ethereum, BNB Chain, Base, Arbitrum, Avalanche, Optimism, Polygon, HyperEVM, Berachain, Linea, Sonic, and Merlin.
• Solana.

The SDK abstracts all of them behind the same method calls, and new chains are added at the network layer—your code rarely changes.

Why this matters for builders

• Zero-fragmentation UX: users fund from any chain, spend wherever they want. Again, no need to bridge.
• Gas-token agnosticism: all the most popular tokens (BNB, SOL, USDT, USDC, ETH) can cover fees, so users rarely need to convert assets to pay for fees, regardless of the target or origin blockchain of these funds.
• Future-proof scope: as Particle plugs in additional EVMs/Solana roll-ups, and as the ecosystem develops, your app inherits that reach automatically.
• Saved time and resources: audits, cross-chain messaging, and liquidity routing are handled by Particle’s infra, not your backend.

Simply, Universal Accounts are plug-and-play access to ALL of Web3 for your dApp. You focus on building your product, and your users can forget what chain they’re on.

Ok, so, how do I integrate?

Below, you can see a video tutorial by Davide Zambiasi, Developer Relations at Particle Network, walking you through the integration process.

Or, if you prefer to explore on your own, the following resources should allow you to get started:

• Chain-Abstracted Apps (ChA) Mini-Course: three bite-sized lessons that take you from init to cross-chain swaps.
• Web Quickstart repo: a ready-to-run demo dApp.
• SDK reference (JS/TS): full API docs, constants & helpers.
• Examples Repository: code examples and apps showcasing UA integrations.

BUT, whatever you do, make sure you get in touch with us! Why?

Because, you’re NOT building alone

Releasing the Universal SDK publicly is only step one. But for us, it doesn’t stop there.

We’re backing integrators with:

• Integration help. Direct support from the Particle team (sign up here!) We care about helping your app be as great as it can be.
• Ecosystem-exclusive workshops. We’re joining forces with the chains we support to educate builders on them through open workshops, tutorials, and videos. These will be periodically published on our main and developer X accounts. Stay tuned for upcoming announcements of workshops with Avalanche, Berachain, and Polygon!
• Co-marketing pushes. With every integration, we’re giving you access to our 1M+ follower base through case studies, social media spotlights, KOL activations, and ecosystem campaigns. We’re pushing hard to put the chain-abstracted ecosystem in the forefront of Web3!
  

If you want to build a chain-agnostic dApp, then we need to talk. Our team’s mandate is to make sure your UA launch is smooth and loud.

The bigger picture

Fragmentation has held Web3 back for as long as there have been multiple chains. Universal Accounts are the first and only live way out of this, which means:

• Developers can ship a dApp once and reach every ecosystem.
• Users stop caring about chains and start using dApps like apps.
• Liquidity stops fracturing; capital efficiency rises across the industry, and a new kind of dApp is born.

It’s time to build something real. Hit us up and let’s get you abstracted.

About Particle Network

Particle Network powers chain abstraction, addressing Web3's fragmentation of users and liquidity. This is enabled by Particle's Universal Accounts, which give users a unified account and balance across all chains.
