How to Bridge Ethereum to Binance Smart Chain

The best way to bridge Ethereum (ETH) to Binance Smart Chain with USD stablecoins like USDT or USDC is with Synapse Protocol. They are the largest and most liquid cross-chain DEX that allows users to swap tokens between two networks like Ethereum Mainnet and BNB Chain.

Their platform allows you to bridge a variety of tokens like ETH, USDC, USDT, DAI, BUSD and more with minimal fees and low slippage to the Binance Smart Chain network from Ethereum mainnet. You can get started in 4 simple steps:

  1. Visit Synapse Protocol and connect your MetaMask account.
  2. Select Ethereum as your Current Chain and BNB Chain as your Destination Chain.
  3. Select the token you want to bridge (e.g USDT or USDC) and the amount.
  4. Review the transaction and select 'Bridge Token'. Your tokens will arrive on BNB in under 2 minutes.

How to Convert ETH to BNB on Metamask

You cannot directly convert ETH to BNB on your Metamask wallet. You will need to first bridge stablecoins to the Binance Smart Chain (as shown above), then visit a BSC DEX like PancakeSwap to trade your BUSD for BNB.

The conversion fee from Ethereum to Binance Coin (BNB) is very low thanks to the BSC Chain's cheap fees. It will cost you a maximum of 10 cents to swap ETH to BNB on PancakeSwap or an equivalent DEX.

Bridge BNB to ETH

If you are looking to bridge your BNB back to ETH, you can follow the exact same process with Synapse Protocol. Simply select BNB Chain as your current network, then Ethereum Mainnet as your destination network and complete the transfer.

The BNB to ETH swap will cost up to $1 because a cross-chain transfer requires more blockspace. The demand for blockspace in a transaction is ultimately what sets the fee on BSC and other networks.

Final Thoughts

Bridging ETH to BSC with USD stablecoins like USDT or USDC is an easy and efficient way to access the DeFi ecosystem of BSC without having to worry about expensive transfer fees. Synapse Protocol is currently one of the best options for bridging tokens between two networks, and it has a smooth user interface that makes cross-chain transactions simple and affordable.

Additionally, users can bridge BNB to ETH using the same platform at very low costs. We recommend giving Synapse a try as it provides one of the best user experiences for cross-chain transfers.
