The Universal Accounts SDK is now public.
You can now build chain-agnostic dApps with it, and take full advantage of our technology in just a few lines of code.
No waitlist, no costs.
π Here's how:

Your users don't need to pick a chain anymore.
Universal Accounts in 7702 mode are live on 9 chains β same address, same asset, zero bridging.

Important news for devs building with Universal Accounts.

TL;DR: Weβre releasing Universal Accounts V2, our biggest upgrade yet. If youβre a project using Universal Accounts or a UniversalX user, this means you need to temporarily withdraw funds from existing Universal Account(s).
To all builders and users:
As you saw above, weβre almost done supercharging our entire protocol.
This upgrade makes Universal Accounts more resilient, powerful, and flexible, allowing you to build high-performance, truly chain-agnostic experiences without any speed or stability trade-offs.
V2 delivers:
β’ Market-leading speed (spot trading now 5Γ faster).
β’ Dramatically improved stability and reliability.
β’ Even smoother external wallet importing via EIP-7702.
β’ Massive @UseUniversalX improvements, such as native support for perpetual futures and prediction markets (see quoted post!)
In other words, weβre fundamentally improving the design of Universal Accounts to allow the full performance of traditional accounts with the flexibility of chain abstraction.
This leap forward will make building with Universal Accounts easier, and massively improve existing dApps using our system. However, a one-time temporary withdrawal of funds will be required during this period for all Universal Accounts as the new protocol is implemented and we move away from the old system.
Our team will remain available to support teams during this migration. Weβll continue to provide updates on the situation as we progress through this upgrade!

EIP-7702 is the biggest UX unlock Ethereum has seen in years.
No new address. No migration, just your EOA, upgraded to a universal account.
We're running a hackathon around it, with over 12k in prizes. With @zerodev_app , @openfort_hq, and @magic_labs.

Server-side Universal Accounts bundle the EIP-7702 authorization inline with your transaction.
No separate delegation tx. No two-step flow.
Just 3 steps:
β Init with your private key
β Create a transaction (the SDK finds the optimal route)
β Sign and send β delegation happens automatically
One tx. Any chain.

If you're building in Web3 in 2026, this report is for you.
The State of Crypto Innovation covers what's actually working:
7702, chain abstraction, intents, modular infra, and what they mean for AI agents on permissionless rails.
Straight from the builders shipping it. π

Today, the 7702 Collective debuts.π
This coalition aims to put crypto's spotlight back where it belongs: beyond narratives and into the trends driving true adoption consolidation.
As our first move, we're publishing The State of Crypto Innovation. This builders-first assessment of cryptoβs maturing infrastructure gathers insights from Web3's top builders on what, exactly, is taking us to the next level.

EIP-7702 lets you upgrade your EOA to a Universal Account β without changing its address or needing migrations. Here's exactly how the authorization works under the hood:

The authorization is a hash you sign with your EOA's private key:
const dataHash = hashAuthorization(userOp.eip7702Auth);
const signature = wallet.signingKey.sign(dataHash);

Once a chain is delegated, you don't re-authorize on every transaction.
The SDK tracks this via eip7702Delegated: true β if the flag is set, the userOp skips the auth step entirely.
You can also query delegation state across chains directly:tsconst deployments = await ua.getEIP7702Deployments();

What if your EOA was already a Universal Account?
Not "migrate to a new address."
Not "deploy a proxy contract."
Your existing EOA. Same address. Same keys. π

Particle now supports EIP-7702 and it changes the equation.
It lets an EOA delegate to a Universal Account β temporarily, reversibly β without changing the address.
One authorization. Your EOA now has gas abstraction and cross-chain execution.
Same address. Zero migration.
