Bridging has become one of the most popular applications for digital assets since the rise of alt-Layer 1 and Layer 2 blockchain protocols. Many users need to find a way to bridge between various blockchain like AVAX to BNB or ETH to Cronos to maximize their yields or take advantage of other opportunities.

We prefer a decentralized cross-chain DEX like Synapse over the Cronos Bridge because centralised bridging protocols are expensive.

Can I bridge from ETH to Cronos?

Yes, there are two ways to bridge from Ethereum to the Cronos network. We recommend using Synapse, it is a bridging protocol that is deployed across multiple chains. They are Ethreum, Terra, Avalanche, Arbitrum, Aurora, Binance Smart Chain, Boba Network, Cronos, DFK Chain, Fantom, Harmony, Polygon, Metis, Moonbeam, Moonriver & Optimism.  

If you want to use an alternative bridging protocol to Synapse, you can do it through the CRO networks native bridge, Cronos Bridge. However, we found that compared to Synapse, the Cronos bridge can be a little bit more expensive when moving from ETH to Cronos. If you would like to avoid high bridging fees, we recommend using Synapse.

How to bridge from ETH to Cronos with Metamask

Unfortunately when bridging between Cronos and Ethereum, the only two cryptocurrencies available to bridge are SYN, the native token of Synapse and gOHM (Olympus DAO). We recommend using the token SYN to use this bridging protocol as Olympus DAO's token has dropped significantly in price and is an extremely volatile token.

Follow the below steps to get started on bridging ETH to CRO:

  1. Visit the Synapse protocol
  2. Select 'Connect Metamask Wallet'
  3. Click ''Ethereum' and 'Cronos' under network
  4. Enter the amount of SYN you want to bridge from ETH to Cronos
  5. Press 'Approve SYN' and follow the prompts

After around 2-3 minutes, your SYN should arrive in your Metamask trust wallet on the Cronos Network. To check if they have arrived, simply click the fox button on your Chrome browser, select the Cronos network and you will see your funds under 'SYN'.

Bridging Fees: Ethereum to Cronos

When bridging cryptocurrencies from the Ethereum network to the Cronos Network, you will need to consider the following fees that are involved.

  1. Transaction fee to deposit funds into your Metamask Trust Wallet from your local exchange or DEX
  2. Transfer of Token from Ethereum Network to the Cronos Network via Synapse

Both transactions will cost you up to $50 USD to move your funds over to the Cronosnetwork. However, once your funds have arrived to the Cronos network, the costs to move funds around comes to about $1 per transaction,.
