Introduction: The Expansion of Arbitrum and Cross-Chain Interoperability in 2025
The Ethereum ecosystem continues to grow in complexity and scale in 2025, pushing more users and developers toward Layer 2 solutions like Arbitrum. Offering a balance between low fees and strong security, Arbitrum has become a favorite platform for DeFi projects, NFT creators, and blockchain developers seeking scalable infrastructure.
But as DeFi and Web3 become more multichain than ever before, no single blockchain can stand on its own. Users frequently need to move their assets between Ethereum, BNB Chain, Polygon, and Arbitrum. That’s where crypto bridges come in—acting as essential infrastructure that lets you send tokens across chains securely, quickly, and with minimal fees.
In this updated guide, we’ll break down the best crypto bridges to Arbitrum in 2025. These bridges stand out for their ease of use, transaction speed, security protocols, and broad support for multiple networks. We start with the leading name of the year—Defiway.
- Defiway Bridge
Defiway has become the bridge of choice in 2025 for thousands of users looking to connect with Arbitrum. Its clean interface and reliable performance make it a standout solution in a crowded field of cross-chain tools.
Defiway supports fast transfers of assets like ETH, USDT, USDC, and other ERC-20 tokens from Ethereum, BNB Chain, Avalanche, and other major blockchains. Its smart routing system automatically finds the cheapest and fastest path for your transaction, saving users both time and gas.
Another major plus is Defiway’s security approach. The platform uses audited smart contracts, transparent logs, and multi-signature authorization to keep assets safe throughout the bridging process. Whether you’re a casual investor or an active DeFi user, Defiway offers an all-in-one bridging solution that’s hard to beat in 2025.
- Hop Protocol
Hop Protocol continues to be one of the most efficient bridges for moving assets between Ethereum and Layer 2 solutions like Arbitrum, Optimism, and Polygon. Its standout feature is speed—Hop uses a liquidity pool model and bonded relayers to deliver fast, low-latency transfers.
Hop is particularly useful for moving ETH, USDC, DAI, and other common tokens. In 2025, the protocol has added new UX features, expanded chain support, and increased liquidity, further improving the speed and reliability of transfers to Arbitrum.
It’s an excellent option for users looking to frequently move funds across Ethereum Layer 2 chains with minimal delay and slippage.
- Synapse Protocol
Synapse Protocol is a cross-chain messaging and liquidity protocol that supports a wide variety of tokens and networks, including Arbitrum. It’s known for offering flexible bridging options and support for complex assets like wrapped tokens and stablecoins.
One of Synapse’s strengths in 2025 is its efficiency in transferring stablecoins like USDT, USDC, and DAI with low slippage and near-instant execution. The platform also provides liquidity incentives and staking, making it a hub for DeFi users looking to both bridge and earn.
Its consistent track record for uptime and smooth transfers makes Synapse a strong competitor among Arbitrum bridges.
- Across Protocol
Across Protocol focuses on fast and affordable L2-to-L2 and L1-to-L2 transfers. Built specifically with speed in mind, Across uses a system of relayers that are incentivized to execute transfers quickly and accurately.
In 2025, Across stands out as one of the most gas-efficient bridges for sending ETH and stablecoins to Arbitrum. Its simple UI, high reliability, and efficient dispute resolution system give it a solid reputation in the bridging space.
If your goal is to send funds fast and with minimal gas costs, Across is an ideal option.
- Stargate Finance
Stargate is a fully composable cross-chain bridge built on LayerZero’s interoperability framework. Unlike most bridges that require wrapped tokens, Stargate supports the transfer of native assets, reducing complexity and risk.
Stargate is popular among liquidity providers and DeFi users because of its integrated staking and farming options. In 2025, it continues to offer deep liquidity and fast execution for stablecoin transfers to Arbitrum.
It’s a powerful choice for users who want a bridge that doubles as a DeFi platform.
- Celer cBridge
Celer’s cBridge has built a solid reputation for providing reliable and scalable bridging services. Supporting more than 40 blockchains, cBridge allows users to move assets to Arbitrum with speed and low transaction fees.
The platform supports many token types, including native tokens, stablecoins, and DeFi assets. In 2025, cBridge features include real-time transaction status tracking, enhanced routing algorithms, and an intuitive dashboard.
It’s especially useful for developers and teams who need to manage liquidity or automate bridging at scale.
- Orbiter Finance
Orbiter Finance offers one of the simplest and fastest ways to move ETH and a few select tokens to Arbitrum. Its peer-to-peer architecture allows users to send ETH to Arbitrum with minimal delays and at low cost.
While Orbiter supports fewer assets than other bridges, it’s perfect for those who need to top up their Arbitrum wallets with ETH quickly, whether for trading or interacting with dApps.
In 2025, Orbiter continues to appeal to traders and power users who prioritize speed and minimal transaction friction.
- Multichain
Multichain (formerly Anyswap) is one of the most expansive bridging protocols in the crypto ecosystem. Supporting more than 70 chains, including Arbitrum, it offers massive flexibility for users moving assets across diverse ecosystems.
It supports both native token transfers and wrapped token movements, and it’s integrated into many wallets and DeFi protocols. While its interface can be overwhelming for first-time users, its power and flexibility are hard to match.
In 2025, Multichain remains a reliable option for users with more advanced bridging needs or those managing assets across many different networks.
- Binance Bridge
For users already within the Binance ecosystem, Binance Bridge is a convenient solution for moving funds to Arbitrum. It allows transfers from BNB Chain and Ethereum to Arbitrum in a few steps, with an easy-to-use interface.
While Binance Bridge may not be as decentralized or flexible as other options, it provides a smooth experience for centralized exchange users or those using Binance Wallet.
In 2025, Binance Bridge is still a solid option for quick transfers between Binance and Arbitrum.
- ChainPort
ChainPort takes a different approach by emphasizing high-security bridging for projects and businesses. Its multi-layer security model, which includes audits, cold wallet custody, and insurance coverage, appeals to institutions and teams managing significant amounts of crypto.
Though not the fastest, ChainPort is designed for those who prioritize asset protection over transaction speed. It supports Arbitrum and continues to grow as a reliable service for high-stakes transfers in 2025.
