The fastest in the world!
Ask your agent about Universal Accounts.
If you aren't using Universal Accounts to trade cross-chain, you're at a major disadvantage.
Behind the scenes, Universal Accounts are powering incredibly ambitious trading tools, because every millisecond counts - and UAs are nearly 2x faster.

With Universal Accounts, that means:
one account, one balance, every chain. Users never pick a network again.

Hackathon kick-off starts in 30 min. ⏳
"From Zero to Cross-Chain" — we'll live-code your existing EOA into a universal account and run a cross-chain flow end to end.
The starter you walk away with becomes your hackathon base.

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

Important news for devs building with Universal Accounts.
TL;DR: We’re releasing Universal Accounts V2, our biggest upgrade yet. If you’re a project using Universal Accounts, this means you need to temporarily withdraw funds from existing Universal Account(s).
TL;DR: We’re releasing Universal Accounts V2, our biggest upgrade yet. If you’re 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, we’re 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:
• Market-leading speed (spot trading now 5× faster).
• Dramatically improved stability and reliability.
• Even smoother external wallet importing via EIP-7702.
• Massive @UseUniversalX improvements, such as native support for perpetual futures and prediction markets (see quoted post!)
In other words, we’re 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. We’ll continue to provide updates on the situation as we progress through this upgrade!

Server-side Universal Accounts bundle the EIP-7702 authorization inline with your transaction.
No separate delegation tx. No two-step flow.
Just 3 steps:
→ Init with your private key
→ Create a transaction (the SDK finds the optimal route)
→ Sign and send — 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. 👇
Today, the 7702 Collective debuts.🔎
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 crypto’s maturing infrastructure gathers insights from Web3's top builders on what, exactly, is taking us to the next level.

Once a chain is delegated, you don't re-authorize on every transaction.
The SDK tracks this via eip7702Delegated: true — 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();

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

When you create a transaction with the UA SDK, the SDK returns a set of userOps.
Some of them include an eip7702Auth field — a signed authorization tuple that tells the EVM: "for this transaction, let this EOA run as this smart contract implementation."
It's chain-specific. It's reversible. And it's scoped to a nonce.

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