9 Best Cross-Chain Bridges in 2025

1. Across.to Bridge, Top Pick for Cross-Chain Transfers Overall

Launched in 2021, Across gained a solid reputation for reliability, efficiency, and security among the year’s top crypto bridges. Thus, it has become the go-to bridge thanks to its speed, low fees, and no-nonsense approach to asset transfers.

Built on an intent-based framework, Across lets users declare what they want to do, and the protocol figures out how. That often leads to faster and cheaper transactions, and Across consistently ranks as one of the most cost-effective bridges in the market.

Supported Blockchains

It supports over 20 chains, including Ethereum, Arbitrum, Optimism, Polygon, Base, zkSync, Linea, Scroll, Blast, Zora, Soneium, Lisk, Ink, World Chain, and others.

Security Architecture

• UMA’s Optimistic Oracle: Across relies on UMA’s single-round dispute oracle. Anyone can submit a proposed outcome (like a price or state update); it gets confirmed if nobody disputes it within a short timeframe.
• Dataworker System: The Dataworker component proposes capital reallocations and refund decisions to the Oracle, helping optimize LP fund use without compromising safety.
• Canonical Asset Transfers: No synthetic tokens, ever. That eliminates an entire category of smart contracts and liquidity risks.

Fee Structure

• Liquidity Provider Fees: Users pay no fee if relayers get repaid on the origin chain. If repayment is handled on the destination chain, a fee applies based on liquidity usage.
• Relayer Fees: These are customizable and set by users to make relaying worth the cost (gas fees, capital risk, opportunity cost). They’re built directly into the transaction spread (input vs. output).

Pros of Across

• Fast Transfers: The relayer model enables almost instant bridging across supported chains.
• Low Fees: Thanks to smart liquidity incentives and competition among relayers.
• High Security: Backed by UMA’s battle-tested optimistic oracle and canonical token model.
• Easy to Use: Clean UI, beginner-friendly experience.
• Real Assets Only: No wrapped tokens, no added trust assumptions.

Cons of Across

• Limited Chain Support: Not as widespread as some aggregators or multi-bridge platforms.
• Relayer Dependency: Speed and cost efficiency depend on active relayer participation.

2. Stargate, Best Crypto Bridge for Native Token Transfers

Stargate is our second top pick for cross-chain bridging. It’s earned serious credibility for handling direct native asset transfers. Moreover, Reddit users often highlight Stargate for its simplicity, deep liquidity, and transparent fee model.

Stargate uses shared liquidity pools to route real assets across chains, unlike traditional bridges that mint synthetic tokens. That means you don’t need to trust third-party wrappers or worry about redemption issues. Just plug in the chain you’re on, the one you want to bridge to, and you’re done in one step.

Supported Chains

Stargate supports a wide range of EVM-compatible Layer 1 and 2 networks, with more rolling in over time. Currently, the protocol supports over 80 chains, including Ethereum, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, Base, Fantom, Metis, Linea, Mantle, and others.

Security Architecture

• Unified Liquidity Pools: Stargate pools assets together across chains, avoiding the common issue of fragmented liquidity. This helps keep transactions smooth and avoids failures from empty destination pools.
• Instant Finality: Once your transfer goes through, it’s final: no rollbacks, reorgs, or stress. That’s a huge win over bridges that rely on synthetic token mechanics.
• ∆ (Delta) Algorithm: This in-house balancing mechanism optimizes liquidity, especially during heavy transaction spikes. It automatically rebalances capital between pools to prevent outages.
• LayerZero’s DVN & Oracle Layer: Stargate uses LayerZero’s Decentralized Validation Network (DVN) and messaging layer to guarantee delivery and state verification between chains.
• Audited Smart Contracts: The codebase is regularly audited and battle-tested for vulnerabilities. You’re not flying blind here.

Fee Structure

• Flat Fee: Each transaction carries a 6 bps fee (0.06%). Five bps go to the treasury, and one bps is reserved for veSTG token holders.
• Gas Costs: Since Stargate runs on LayerZero, users also pay gas fees using the destination chain’s native token. These cover execution and message verification through DVN.
• V2 Dynamic Fees (AIPM): Stargate v2 introduced the AI Planning Module, which adjusts fees based on liquidity pressure. If a pool runs low, Stargate offers rebates to incentivize users to help rebalance it. It’s smart, but might surprise folks who are used to flat pricing.

Pros of Stargate

• Native Transfers: No wrapped tokens, just real assets, end-to-end.
• Wide Chain Support: Compatible with a long list of EVM chains.
• High Liquidity: Large TVL means more efficient bridging and lower slippage.
• Transparent Pricing: See slippage and fees before you confirm.
• Liquidity Rewards: Provide liquidity and earn STG tokens.
• Simple Interface: Designed with usability in mind, excellent for all levels.

Cons of Stargate

• Variable Fees: The AI-managed dynamic fees might throw off users expecting consistency.
• Liquidity Pressure: Pools can still run low during peak demand.
• Gas Overhead: LayerZero execution adds a bit of gas cost.

FAQ

What is a Cross-Chain Crypto Bridge?

A cross-chain crypto bridge is a protocol for moving assets (like tokens or NFTs) across different blockchain networks. It connects ecosystems like Ethereum, BNB Chain, and Polygon, enabling cross-chain transfers without needing a centralized exchange. 

Why Do People Bridge Crypto Assets?

People bridge crypto assets to access lower fees, faster networks, or tokens that only exist on a specific destination chain. It’s also common when managing funds across multiple chains for trading, staking, or farming.

How Do You Bridge Crypto Tokens?

Connect your wallet, pick the token and network you want to bridge from, and then choose your destination chain. Enter the amount, review the quote, and confirm the transaction. The bridge handles the rest, and your assets show up on the new chain in minutes.

Are Cross-Chain Bridges Safe?

Many are, but not all. Security depends on the bridge’s smart contracts, validator setup, and transparency. Look for platforms with audits, clear fee structures, and strong reputations. Redditors often flag issues early, so it’s worth checking community feedback before moving large amounts.

Conclusion

Hopefully, now you know which crypto bridges will be the most popular in 2025. Whether you want to transfer tokens more efficiently or explore new chains, these tools prove how blockchain bridges enable a truly connected Web3 experience.

Choose wisely, and bridge safely!
