About the ETH to BNB swap

Why swap ETH to BNB. BNB pays gas on BNB Chain and opens its DeFi and launchpads. Swapping ETH to BNB moves value from the Ethereum ecosystem into BNB Chain without an exchange.
Which ETH you can use. ETH on Ethereum, Base, Arbitrum One or Robinhood. Over the 90 days to 29 September 2026, most ETH to BNB volume on Symbiosis came from Robinhood (64%) and Ethereum (29%).
What you receive. Native BNB on BNB Chain in the wallet you connect, such as MetaMask or Trust Wallet — not a wrapped token.
Cost and speed. On 6 October 2026, 0.4 ETH returned about 1.376 BNB from every network, with fees from $4.28 from Arbitrum One to $5.17 from Robinhood. Over the 90 days to 29 September 2026, the median ETH to BNB swap took 38 seconds.

Swap ETH to BNB in Symbiosis PRO mode: 0.4 ETH (Ethereum) to 1.3752 BNB (BNB Chain)

How to swap ETH to BNB

Example quote from 6 October 2026: swapping 0.4 ETH (~$1,080) on Ethereum in the Symbiosis app returns about 1.3752 BNB on BNB Chain, delivered in about 78 seconds. Symbiosis aggregates liquidity from many DEXes and selects the most efficient route automatically. Here is the flow:

Open the swap. Go to the Symbiosis app and connect an Ethereum wallet such as MetaMask. There is no sign-up and no KYC.
Pick the token you send. Choose ETH on Ethereum in the From field.
Choose BNB on BNB Chain. Set BNB as the token to receive and BNB Chain as the destination network. Enter the amount: 0.4 ETH (~$1,080).
Check the quote. Before you sign, the app shows how much BNB you get, the fee, price impact and time. In this example: about 1.3752 BNB, a $1.35 route fee, with 2% slippage tolerance.
Sign and receive. Confirm the transaction in your wallet; BNB lands in your wallet on BNB Chain.

ROUTE ESTIMATES

Sample ETH to BNB quotes

Symbiosis quotes for 0.4 ETH to BNB from four networks, taken in the Symbiosis app on 6 October 2026. Receive is the amount of BNB that lands in your wallet on BNB Chain. Fee is the full cost in USD as shown in the Symbiosis app — the value you send minus the value you receive, never less than the route fee — plus source-network gas. Time is the median delivery time from each network to BNB Chain over the 90 days to 29 September 2026; for a swap inside one network, the app estimate.
