Top 9 Crypto Bridges to Use in 2025

Crypto has changed since its inception. In today’s crypto industry, taking full advantage of decentralized finance often means interacting with multiple blockchains. Having a reliable bridge is indispensable for moving tokens between these platforms.

However, there’s a problem: many users use popular options like the Portal Token Bridge or Synapse Bridge for these transfers. While they are solid choices, plenty of other platforms are out there—many of which might offer even better features for your needs.

In this article, we’ve rounded up the best crypto bridges of 2025. We’ve carefully evaluated them based on factors like supported networks, security, fees, and overall functionality, making finding the perfect platform for cross-chain transfers easier.

What are Crypto Bridges, and Why are they Important for Web3 and DeFi?

Crypto bridges (or blockchain bridges) are software protocols that connect different blockchains, allowing them to communicate and work together, much like a bridge connecting two separate islands.

They work by linking two separate blockchains, making it possible to move assets and data between them seamlessly. These bridges use shared liquidity pools and smart balancing systems to ensure smooth and efficient transfers. The liquidity pools hold native assets for multiple blockchains simultaneously, allowing quick and easy swaps.

With a crypto bridge, you can transfer your assets directly between blockchains in just a few clicks, saving you from the hassle of using a centralized exchange, where you’d have to deposit your assets, trade them, and then withdraw them again.

Using bridges reduces delays and eliminates the need to trust a centralized exchange. Plus, since centralized exchanges often charge hefty fees, decentralized bridges can help you save money on transactions, besides the fact that most decentralized apps don’t require KYC.

Top 9 Best Bridges in Crypto  

Across.to


Launched in 2021, Across Protocol is a popular cross-chain solution using intents, and we consider it the best platform for bridging at the time of writing.

What sets Across apart is that it only transfers real, canonical assets, not wrapped or synthetic tokens. It operates on chains with official bridges to ensure genuine token transfers.

Supported Chains

There are over 17 supported chains available: Aleph Zero, Blast, zkSync, Optimism, Base, Arbitrum, Soneium, Ethereum, Polygon, Ink, Mode, Redstone, Scroll, World Chain, Zora, Lisk, and Linea.

Security

Across Protocol prioritizes user security with several key features:

  • UMA’s Optimistic Oracle – The protocol relies on UMA’s optimistic oracle, which uses a one-step dispute mechanism. Anyone can propose answers to specific questions, and if undisputed within a short time frame, the answer is verified.
  • Dataworker Proposals – The Dataworker submits proposals to the optimistic oracle for valid refunds and optimal reallocations of liquidity provider (LP) capital, improving capital efficiency while maintaining security.
  • Canonical Token Transfers – Across exclusively handles genuine (canonical) assets, avoiding the risks associated with synthetic or wrapped tokens. 

Fees

Across Protocol charges liquidity provider fees based on whether the relayer takes repayment from the origin or destination chain. If repayment happens on the origin chain, no fees are charged; otherwise, a fee based on liquidity utilization is applied.
