Summary: The best way to bridge from ETH to Cronos by using your MetaMask account is by going through Synapse, the world's largest multi-chain bridging protocol.
Their platform allows users to seamlessly swap ETH, USDT, USDC and CRO between Ethereum mainnet and the Cronos blockchain by Crypto.com.
- Fastest and most trusted Ethereum to Cronos cross-chain DEX.
- Lowest fees and slippage for cross-chain swaps (WETH, CRO, USDC, OHM, USDT).
- Synapse's ETH and CRO bridge has the most trading volume in DeFi.
Can I Bridge to Cronos?
Yes, you can effortlessly bridge to Cronos, a rising Layer 1 network. This requires using a sturdy cross-chain bridge to transfer assets such as ETH or USDT from Ethereum Layer 1, a different Layer 1, or even a Layer 2, directly to Cronos. During the bridging process, your assets are temporarily stored in a secure smart contract within the original network to prevent double-spending. Then, these safely kept assets are swiftly transferred to your wallet on Cronos, ensuring a secure transition to this network.
How to Bridge from Ethereum to Cronos
When considering a bridge between the Cronos and Ethereum networks, only two tokens, SYN (the native token of Synapse) and gOHM (from Olympus DAO), are currently available for this purpose. We highly recommend using SYN for this process due to its speed and stability. The bridging process should typically take around 5 to 10 minutes and the price of SYN should remain relatively stable within this short timeframe.
Here are the step-by-step instructions to commence your bridge from Ethereum to Cronos:
- Navigate to the Synapse protocol website.
- Select 'Connect Metamask Wallet'.
- Specify the amount of SYN you wish to bridge from Ethereum to Cronos.
- Click 'Approve SYN' and follow the prompts within your Metamask wallet to complete your transaction.

Alternative Cronos Bridges
If you would like to use an alternative bridge to Synapse to move your assets from ETH to Cronos, then you can do it natively through the Cronos Bridge. This is a secure bridge built by the Cronos and Crypto.com team to facilitate cross-chain transfers. We found that compared to Synapse, the Cronos bridge can be a little bit more expensive when moving from ETH to Cronos, or AVAX to Cronos.
ETH to Cronos Bridge Fees
When you're planning to bridge your SYN tokens from the Ethereum Chain to the Cronos Chain, it's crucial to be aware of the associated fees. These charges come in two parts:
- A transaction fee for depositing SYN into your Metamask Wallet.
- A fee for bridging SYN from Ethereum to Cronos.
The total cost for both transactions can reach up to $50 USD, and this is required to transfer your funds over to the Cronos network. Once your assets have arrived on the Cronos network, further transactions become significantly more economical, costing around 30 cents per operation. This reduced rate is thanks to the much lower gas fees on the Cronos network compared to those on the Ethereum network. This feature makes Cronos an attractive choice for users seeking cost-efficient operations.
Final Thoughts
In conclusion, bridging to the burgeoning Cronos Layer 1 network is an achievable process involving a reliable cross-chain bridge, allowing for the secure transfer of assets such as ETH or USDT. The two main routes for bridging include the SYN token via the Synapse protocol or directly through the native Cronos Bridge. While each approach carries associated fees, the considerably lower transaction costs on the Cronos network post-transfer position it as a compelling option for users looking for cost-efficient operations. Whether you choose Synapse or the Cronos Bridge, each pathway promises a secure and efficient bridging experience to the Cronos network.
