Orbiter Finance charges 0.03% to 0.30% plus a withholding fee to cover gas fees for transactions to the destination network. The exact fee depends on the destination network and current network conditions.
Founded in 2021, the Arbitrum Bridge is a popular cross-chain bridge with an overall score of 3.86 out of 5. It made it to our list of the best cross-chain bridges for its interoperability with the Ethereum mainnet and the solutions it offers such as reduced gas fees, high EVM compatibility, and increased transaction speeds.
Arbitrum Bridge supports Ethereum and Arbitrum networks along with 35+ Orbit Chains and is primarily focused on ERC-20 tokens.
Arbitrum, unlike most Layer-2 cross-chain crypto bridges, uses 2 mainnets: Arbitrum Nova and Arbitrum One. Both of these mainnets operate differently.
Arbitrum One ensures that posted transaction data is valid using multiple-round interactive optimistic rollups while Arbitrum Nova uses the AnyTrust model to ensure that transaction data is accurate.
It can offer low trading fees using the Data Availability Committee security model that provides certificates for correct transactions.
The Arbitrum Bridge has a permissionless environment that allows anyone to stake the ARB token and become a validator.
Validators are incentivized and mandated to stake assets to ensure compliance with the cross-chain bridge rules.
In the event of malicious behavior exhibited by validators, the Arbitrum cross-chain bridge has mechanisms set to identify and fix all irregularities.
The Arbitrum Bridge charges an average of $0.25 for transactions, though fees can vary based on network congestion and transaction complexity.
Founded in 2020, the Binance Bridge has an overall score of 3.68 out of 5. It supports multiple cryptocurrencies across 3-5 primary blockchain networks including Ethereum, BNB Chain, and connected networks.
It stands out for unlocking interoperability between ERC-20 and BEP-2/BEP-20 tokens.
This enables users to cut down on fees while maintaining the efficiency of the blockchains.
The native token of the Binance Bridge is Binance Coin (BNB).
Binance Bridge users can use Peg-in and Peg-out to transfer crypto assets in and out of different blockchains.
With the Peg-in method users can exchange native tokens in exchange for the equivalent amount of the pegged tokens in the Binance Smart Chain or Binance Chain.
Peg-out, on the other hand, allows users to swap the pegged tokens for native tokens.
The Binance Bridge uses the same security standards as the Binance Chain ecosystem.
All transactions are completed without third-party involvement because they can only be completed using a Binance account.
The Binance Bridge charges $1-5 depending on the specific bridging operation and network conditions.
Founded in 2021, Hop Protocol has an overall score of 3.48 out of 5. It’s one of the established cross-chain bridges for facilitating fast movement of assets through sidechains, Layer 2 solutions, and Layer 1 blockchains.
Hop Protocol supports 5 different blockchain networks including Ethereum, Arbitrum, Optimism, Polygon, and Gnosis, with 6 cryptocurrencies including Ethereum, USDT, USDC, DAI, Polygon, and HOP.
It has a native token known as the HOP token.
The Hop Protocol native token (HOP) is the native token of the Hop ecosystem. It is a cross-network bridge token transferred from rollup to rollup and is claimed on Layer 2 for the underlying assets.
It serves as an intermediary bridge token that enables trustless swaps.
Hop Protocol ensures secure cross-chain transfers using several security measures. It is a non-custodial bridge, meaning users’ funds and liquidity providers in the AMM are not controlled by a single entity.
Hop Protocol has been audited by leading external auditors.
Hop Protocol charges multiple fees including a minimum fee of $0.25, bonder fees of 0.05-0.30%, destination chain transaction fees (dynamic gas fees), slippage (dynamic), and AMM swap fees of 0.04%.
Founded in 2020, Orbit Bridge has an overall score of 3.22 out of 5. Like other popular cross-chain bridges on this list, it enables users to transfer cryptocurrencies across different blockchains.
It supports 15+ different blockchain networks including Ethereum, BNB Chain, HECO, Polygon, Ripple, Klaytn, Celo, Avalanche, and Stacks, with 100+ assets including USDT, ETH, USDC, REN, DAI, ANT, OMG, TRIX, CELO, and DON.
The cross-chain bridge made it to our list for its dynamic trading fees that adjust based on network conditions and the specific bridging operation.
Using this consensus mechanism, the Orbit Bridge process involves an operator that sends data and a validator that works together to quickly validate transactions.
The consensus and validation process on Orbit Bridge is trustless and transparent.
There is no centralized control on validators for them to complete tasks.
The primary security feature of the Orbit Chain is that it is open source. This enables users to create their vaults to deposit assets when bridging tokens on the Orbit Chain with custom consensus.
Validators also operate without a central authority which provides more decentralization.
The Orbit Bridge charges dynamic trading fees for cross-chain bridging depending on the blockchain networks involved in the transfer and current market conditions.

Cross-chain bridges are protocols that allow users to transfer assets between different blockchains, execute smart contracts and leverage the strengths of different blockchain ecosystems. For example, cross-chain bridges allow users to transfer an asset from Solana to Ethereum or from Polygon to Arbitrum.
These bridges solve the blockchain interoperability problem by creating secure pathways for assets and data to move between different networks that would otherwise be incompatible.
Bridging in crypto offers significant benefits for accessing DeFi protocols across multiple chains, but it comes with inherent risks and challenges.
The primary security concern is that bridges serve as critical points of communication between networks, making them attractive targets for hackers. Users should always verify bridge security audits, understand the specific risks of each protocol, and only use well-established bridges with strong track records.
There are many cross-chain bridges available, so choosing the right one involves considering several key factors:
Blockchain interoperability remains a major challenge in the crypto ecosystem, and cross-chain bridges provide essential solutions to this problem. However, not all bridges are created equal, and the right choice depends on your specific needs.
Based on our comprehensive analysis, Across Protocol emerges as the top choice for users seeking the best combination of low fees, security, and capital efficiency. For users requiring broader network support, Stargate Finance and Synapse Protocol offer excellent alternatives with extensive blockchain coverage.
Always remember to research each bridge thoroughly, start with small amounts, and understand the risks involved before committing large sums to any cross-chain transfer.
