Cross-chain asset transfers have become a cornerstone of the decentralized finance (DeFi) ecosystem. As users diversify across blockchains like Ethereum, Arbitrum, Optimism, and Base, the need for fast, secure, and affordable bridges has never been greater. Yet, many existing solutions fall short—plagued by delays, high fees, and security vulnerabilities.
Enter Across Protocol, a leading cross-chain bridge redefining what’s possible in blockchain interoperability. With over 2 million users, 8 million completed transfers, and nearly $12 billion in total volume, Across has emerged as a top choice for both beginners and experienced crypto users.
But what makes it stand out? Let’s explore how Across solves the most common pain points in cross-chain bridging—and why it might be the ideal solution for your needs.
The Challenges of Traditional Cross-Chain Bridges
Transferring assets between blockchains shouldn’t feel like navigating a minefield. Unfortunately, many bridges today present one or more of the following issues:
- High fees: Some bridges charge exorbitant fees, especially during network congestion, cutting into your transferred amount.
- Slow transaction times: Waiting hours—or even days—for funds to arrive defeats the purpose of a seamless DeFi experience.
- Security risks: Numerous bridges have suffered exploits due to weak smart contract design or reliance on untrusted third parties.
- Complex user experience: Confusing interfaces and technical jargon can deter newcomers and frustrate even seasoned users.
These challenges not only hinder usability but also compromise trust in cross-chain infrastructure. That’s where Across steps in with a smarter, safer approach.

How Across Transforms Cross-Chain Transfers
Across Protocol addresses the core shortcomings of traditional bridges through innovative technology, user-centric design, and robust security practices.
Blazing-Fast Transfer Speeds
Speed is critical when moving assets—especially when arbitrage opportunities or time-sensitive DeFi strategies are involved. Across boasts a median fill time of just 3 seconds, making it the fastest bridge within the Ethereum ecosystem.
Compare this to competitors:
- Stargate: 18 seconds
- Synapse: 19 seconds
- Hop Protocol: 36 seconds
This performance is powered by Across’s intents-based relayer system, which enables near-instant delivery of assets on the destination chain. While transfer speeds may vary slightly depending on the route (e.g., Ethereum Mainnet to L2 vs. L2-to-L2), Across consistently leads in speed across aggregated data from all supported chains.
Ultra-Low Bridging Fees
Cost efficiency matters—whether you're transferring $50 or $50,000. Across maintains a median bridging fee of only $0.05, positioning it among the most affordable options available. This low cost structure ensures that users retain more of their capital, enhancing overall yield in cross-chain strategies.
Enterprise-Grade Security
Security is non-negotiable. Across runs on audited smart contracts and avoids high-risk models used by some third-party bridges (like LayerZero). While many cross-chain protocols rely on "Lock and Mint" mechanisms that expose users to custodial risks, Across mitigates these threats through its decentralized relayer network.
Relayers front liquidity to users on the destination chain, taking on the risk themselves in exchange for rewards. This means you face zero risk during the bridging process—your funds are never locked in an insecure contract or exposed to bridge-specific exploits.
