The decentralized finance (DeFi) landscape continues to evolve at a rapid pace, and one of the most significant advancements in recent months is the integration of Across into Uniswap Labs' ecosystem. This collaboration introduces seamless, secure, and lightning-fast cross-chain bridging directly within the Uniswap app—marking a major leap forward in user experience and blockchain interoperability.
For millions of DeFi users, navigating multiple blockchains has long been a fragmented and technically demanding process. Now, with Across-powered bridging, Uniswap simplifies crosschain transfers of ETH, stablecoins, and wBTC across nine major EVM-compatible chains—without ever leaving the interface.
The Crosschain Challenge in DeFi
As Ethereum’s network grew, so did the need for scalability. Layer 2 (L2) solutions like Arbitrum, Optimism, and Base emerged to handle rising transaction volumes. While these networks improved speed and reduced fees, they also created a new problem: fragmentation.
Users found themselves locked into individual ecosystems, forced to use third-party bridges that often came with complex steps, high risk, or long wait times. Many bridges rely on lock-and-mint models or trust assumptions that expose users to smart contract vulnerabilities or chain reorganizations (reorgs).
This friction contradicts the core promise of Web3: open, seamless access to digital assets.

That’s where intent-based architecture comes in—a paradigm shift that prioritizes user safety and simplicity.
How Across Solves Interoperability
Across introduces a novel approach to cross-chain transfers by leveraging cross-chain intents, a concept that shifts responsibility away from the end user and onto a secure, incentive-aligned infrastructure.
Rather than requiring users to manually select bridges, verify confirmations, or worry about timing risks, Across abstracts all complexity. When a user initiates a transfer, they express an intent—for example, “I want 1 ETH on Arbitrum”—and the protocol handles execution securely and efficiently.
Key benefits include:
- Sub-3-second transfers for transactions under $10,000 (which account for 99% of L2 bridging activity)
- Elimination of reorg risk through real-time monitoring and bonding mechanisms
- No need to trust bridge operators due to its permissionless, decentralized design
- Native support for native assets, stablecoins, and wrapped BTC
This means users get Web2-level convenience with Web3 sovereignty—a critical milestone for mainstream adoption.
In-App Bridging Now Live on Uniswap
Starting today, Uniswap users can bridge assets directly within the Uniswap app across nine supported chains:
- Ethereum
- Base
- Arbitrum
- Polygon
- OP Mainnet
- Zora
- Blast
- World Chain
- ZKsync
The integration supports like-asset transfers, meaning you can send ETH from Ethereum to ETH on Arbitrum, USDC from Base to USDC on Polygon, or wBTC from OP Mainnet to wBTC on ZKsync—all without switching apps or trusting opaque third parties.
This isn’t just about convenience—it’s about unifying the Ethereum ecosystem. Instead of treating each L2 as a siloed network, Uniswap and Across are helping turn them into interconnected layers of a single, scalable financial system.

The Future: ERC-7683 and Standardized Intents
Looking ahead, Uniswap Labs and Across are co-leading the development of ERC-7683, a new Ethereum standard designed to formalize how cross-chain actions are expressed as intents.
This standard could become foundational for future dApps, wallets, and infrastructure projects aiming to offer seamless multi-chain experiences. By defining a common language for intent expression, ERC-7683 reduces fragmentation and enables interoperability at the protocol level—not just the application layer.
Imagine a world where any wallet or exchange can interpret your intent to “move 500 USDC from Polygon to Base” and execute it optimally, securely, and instantly. That future is now within reach.
Frequently Asked Questions (FAQ)
Q: What is intent-based bridging?
A: Intent-based bridging allows users to declare their desired outcome (e.g., “I want ETH on Arbitrum”) without managing technical details. The protocol then finds the safest, fastest route to fulfill that intent.
Q: Is Across safe to use?
A: Yes. Across eliminates common risks like reorgs and smart contract exploits through real-time monitoring, bonded relayers, and decentralized verification—making it one of the most secure bridging options available.
Q: Which tokens can I bridge via Uniswap?
A: You can transfer native assets (like ETH), major stablecoins (such as USDC and DAI), and wBTC across all nine supported chains.
Q: Are there fees for using Across on Uniswap?
A: Yes, but they’re optimized for speed and cost-efficiency. Fees vary based on network congestion and destination chain, but small transfers (<$10K) typically incur low costs with near-instant finality.
Q: Do I need a new wallet to use this feature?
A: No. The bridging functionality works within the existing Uniswap interface and Uniswap Wallet—no additional setup required.
Q: How fast are transfers between L2s?
A: For transfers under $10,000, most complete in under 3 seconds thanks to Across’s optimized routing and bonding mechanism.
