Cross-chain bridges are essential tools in today’s decentralized finance (DeFi) landscape, enabling users to transfer tokens across different blockchain networks seamlessly. As multi-chain activity grows, so does the need for reliable, secure, and efficient bridge solutions. This guide explores the top 8 crypto bridges available today, evaluated based on liquidity, supported blockchains, user experience, security, and additional features.
Whether you're moving assets from Ethereum to a Layer 2 network or bridging stablecoins to Solana, choosing the right bridge can make a significant difference in speed, cost, and safety.

What Are Cross-Chain Bridges?
A cross-chain bridge allows digital assets and data to be transferred between separate blockchain ecosystems. These bridges unlock interoperability, letting users access DeFi applications, NFT markets, and liquidity pools across various chains such as Ethereum, BNB Chain, Polygon, Arbitrum, and Solana.
However, it's important to note that bridges are frequent targets for hackers due to the large amounts of locked value. Several high-profile exploits have occurred in recent years, emphasizing the need for caution. Always use well-audited, reputable bridges and avoid transferring more than you can afford to lose.
Now, let’s dive into the best crypto bridges currently available.
1. Synapse Protocol
Synapse Protocol stands out as one of the most robust and versatile cross-chain bridges on the market. It supports both EVM and non-EVM blockchains, making it ideal for users navigating diverse ecosystems.
With Synapse Bridge, you can transfer not only tokens but also NFTs and arbitrary data across chains. This opens up possibilities for advanced cross-chain smart contract interactions. Supported networks include Ethereum, BNB Chain, Fantom, Arbitrum, Optimism, and more.
As of now, Synapse Protocol holds a Total Value Locked (TVL) of approximately $103 million, according to DeFi Llama — a strong indicator of user trust and liquidity depth.
Key Features:
- Aggregates liquidity from multiple sources to reduce slippage
- Uses optimized smart contracts and Layer 2 scaling solutions
- Supports cross-chain staking and yield farming
- Integrated with decentralized exchanges and launchpads
- Native SYN token used for governance and staking rewards
Synapse is particularly valuable for users who want a single interface for complex multi-chain operations.

2. Portal Token Bridge
Powered by the Wormhole protocol, Portal Token Bridge offers extensive support for both EVM and non-EVM blockchains. It enables users to lock tokens on one chain and mint wrapped versions on another, ensuring consistent value across ecosystems.
One of Portal’s standout strengths is its support for emerging blockchains like Sui, Sei, Near, and Aptos — networks often missing from other major bridges. It also fully supports mainstream chains including Ethereum, Solana, Polygon, and BNB Chain.
Additionally, Portal includes an NFT bridge that facilitates transfers of ERC-721 and SPL-standard NFTs between compatible chains.
Key Features:
- Built on the secure Wormhole interoperability protocol
- Broad blockchain support including niche ecosystems
- Dedicated NFT bridging functionality
- Enables cross-chain staking opportunities
For users deeply involved in newer or Solana-based ecosystems, Portal Token Bridge provides unmatched flexibility.
3. Allbridge
Allbridge delivers a reliable bridging solution for transferring assets between EVM and non-EVM chains — especially useful for moving stablecoins to and from Solana.
It offers two distinct products:
- Allbridge Core: Focused on stablecoin transfers between chains (e.g., USDT on Ethereum to USDC on Solana)
- Allbridge Classic: A general-purpose bridge supporting 24 different blockchains
Allbridge Core currently maintains around $70.1 million in stablecoin liquidity across 13 pools — sufficient for most retail transfers. Both products have undergone audits by reputable firms including Hacken and Kudelski Security.
Key Features:
- Supports EVM (Ethereum, Polygon) and non-EVM (Solana, Terra) chains
- Dual-bridge architecture for specialized use cases
- Audited by leading cybersecurity firms
- Wide multi-chain coverage
Allbridge is an excellent choice for stablecoin-centric workflows across fragmented blockchain environments.
4. Arbitrum Bridge
The official Arbitrum Bridge is the go-to option for transferring assets between Ethereum and Arbitrum — one of the largest Layer 2 networks by TVL ($16.2 billion).
Transactions from Ethereum to Arbitrum complete quickly, though withdrawals back to Ethereum require a ~7-day challenge period due to security mechanisms. Despite this delay, the bridge offers seamless integration with wallets like MetaMask and full compatibility with dApps on both chains.
Key Features:
- Drastically reduced transaction fees compared to Ethereum mainnet
- Uses optimistic rollup technology to batch transactions
- Inherits Ethereum’s security through consensus finality
- Developer-friendly design with robust documentation
While limited to Ethereum, Arbitrum One, and Arbitrum Nova, this bridge remains essential for anyone active in the Arbitrum ecosystem.
5. Celer cBridge
Celer cBridge supports an impressive 40+ blockchains, ranging from Ethereum and Arbitrum to niche networks like Canto, Shiden, and Aurora.
Backed by the Celer Network’s interoperability protocol, cBridge uses the Celer State Guardian Network (SGN) — a PoS blockchain that monitors Layer 1 events and validates cross-chain messages.
Key Features:
- Supports token and NFT transfers
- High chain diversity with strong Layer 2 coverage
- Powered by a dedicated validator network
- Non-custodial and trust-minimized design
Its wide reach makes Celer cBridge ideal for power users managing portfolios across many chains.
6. Stargate Token Bridge
Stargate combines a clean UI with deep DeFi functionality. It supports multiple EVM-compatible Layer 1 and Layer 2 networks and provides real-time estimates for slippage and gas costs before each transfer.
Users can also provide liquidity to earn STG rewards or stake STG to receive veSTG for governance rights. With a TVL of $332 million, Stargate ranks among the largest cross-chain protocols.
Key Features:
- Real-time cost estimation before transfers
- Liquidity provision with yield opportunities
- Governance through veToken model
- High liquidity across major EVM chains
Stargate excels in transparency and user empowerment.
7. Hop Protocol
Hop Protocol specializes in fast transfers between Ethereum Layer 2s, including Optimism, Arbitrum, Base, Polygon zkEVM, and Gnosis.
It achieves near-instant deposits by using bonders — third-party liquidity providers — who front funds on the destination chain while waiting for on-chain confirmation.
Key Features:
- Near-instant L2-to-L2 transfers
- Fully non-custodial design
- Audited by Solidified and Monoceros Alpha
- Supports major Ethereum scaling solutions
Hop is perfect for traders and DeFi users frequently switching between rollups.
8. Connext
Connext enables cross-chain communication via its xCall technology, supporting various EVM chains and Layer 2s like Arbitrum and Optimism.
It introduces the xERC20 standard — a cross-chain extension of ERC20 — allowing tokens to operate natively across ecosystems without wrapping.
Key Features:
- Native cross-chain token standard (xERC20)
- Flexible gas payment options
- Customizable slippage tolerance
- Developer-focused tooling for dApp builders
Though liquidity is currently lower than competitors, Connext shows strong potential for future integrations.
Frequently Asked Questions (FAQ)
Q: Are cross-chain bridges safe?
A: While many bridges are secure and audited, they remain high-value targets for hackers. Always research a bridge’s audit history, team reputation, and TVL before use.
Q: How long do bridge transfers take?
A: Times vary — some L2 bridges complete in minutes, while others (like Arbitrum withdrawals) may take up to a week due to security delays.
Q: Can I bridge NFTs?
A: Yes — platforms like Portal Token Bridge and Celer cBridge support NFT transfers across compatible chains.
Q: What causes high slippage when bridging?
A: Low liquidity pools or large transaction sizes can increase slippage. Use bridges with aggregated liquidity (e.g., Synapse) to minimize this.
Q: Do I need gas on both chains?
A: Typically yes — you’ll need native tokens (e.g., ETH, MATIC) on both source and destination chains to pay for transactions.
Q: Which bridge has the lowest fees?
A: Fees depend on network congestion. Generally, bridges using Layer 2s (like Hop or Arbitrum Bridge) offer lower costs than mainnet-only options.
Choosing the right crypto bridge depends on your specific needs — whether it’s speed, chain compatibility, NFT support, or yield opportunities. The platforms listed above represent the most secure, functional, and widely adopted solutions in 2025’s evolving multi-chain world.
