Decentralized finance (DeFi) thrives on interoperability, requiring users to move assets across multiple blockchains. Crypto bridges facilitate these cross-chain transfers by connecting disparate networks. This guide explores the top 9 crypto bridges, evaluating them based on liquidity, supported chains, security, and user experience.
Top 9 Crypto Bridges for Cross-Chain Swaps

- Synapse Protocol – Best overall crypto bridge platform.
- Portal Token Bridge – Supports EVM and non-EVM chains.
- Allbridge – Reliable solution for Solana and other non-EVM chains.
- Stargate – Diverse platform support with low slippage.
- Arbitrum Bridge – Ideal for Ethereum-Arbitrum transfers.
- Celer cBridge – Celer Network’s expansive bridging tool.
- Hop Protocol – Specialized for Ethereum Layer 2s.
- Connext – EVM and Layer 2-focused bridge.
