🌉ERC20 to BEP20 — Complete Guide
Introduction
Cross-chain swapping can be done through multiple ways, each one having its own ups and downs.
When it comes to Binance Smart Chain, the easiest way to cross-chain swap your tokens is through Binance, being it the exchange itself or the Binance Bridge, but there are two other methods in which Binance has little use or none at all that we will explain to you here.
Methods for countries in which Binance allows BEP20 withdrawals:
For example, most countries in Europe.
Binance Exchange: Deposit ERC20 Tokens into Binance and withdraw to your BSC wallet as BEP20.
Binance Bridge: Use Binance's own bridge to transfer between blockchains without an account.
Methods for countries in which Binance does not allow BEP20 withdrawals:
For example, USA.
SafePal App: Cross-chain swap ERC20 ETH for BEP20 BNB directly in your wallet.
Trust Wallet: Withdraw BEP2 from Binance into your wallet and cross-chain swap BEP2 to BEP20.
Binance Browser Extension: Withdraw BEP2 from Binance into your wallet and cross-chain swap BEP2 to BEP20.

Now that you're all set, pick the desired method from the tabs below:
The following method is simplest, all you have to do being:
Deposit the tokens from Ethereum into Binance Exchange.
Withdraw the tokens from Binance Exchange as BEP20 into your BSC wallet.
1) Deposit your tokens on Binance Exchange
Find the token you want to deposit in your "spot wallet", click on "deposit", copy the address and send your tokens to that address.
2) Withdraw the desired tokens in your external BSC wallet.
Find the token you want to withdraw in your "spot wallet", click on "withdraw", and fill the boxes with the correct info.
That's it.
Additional information
Make sure you also buy and withdraw at least a few USD of BNB for transactional fees, as Binance Smart Chain uses BNB to pay the validator's fees, the same way Ethereum uses ETH (but BSC is doing it x100 times cheaper).
The following method is the most convenient, because it's the only method on our list today that also gives you the option to receive BNB (for fees), no matter what asset you're cross-chain swapping.
1) Go to the Binance Bridge and connect your wallet
2) Pick the asset you want to cross-chain swap from the list
3) Pick the correct "from" and "to" blockchain options and the destination
In our case, we want to cross-chain swap from Ethereum Network into Binance Smart Chain Network. The destination address was automatically chosen for us, as on MetaMask your ERC20 address and BEP20 address are identical (this does not apply to every wallet).
4-1) Check the "I want to swap some BNB..." box and pick an option
How much BNB you decide to get is entirely up to you, as once you have at least the minimum necessary you can always swap the assets you just cross-chain swapped for more BNB on Kalmar.
4-2) Pick the correct option.
In our case it is the 4th one, because we will send the tokens directly from our wallet.
5) Confirm the transaction
6) Copy the address and send the tokens to it
Make sure to always send only one transaction and that the amount is correct.
7) Wait for the transaction to be confirmed 12 times
8) Done, we received our 1 BNB and the rest of our ETH.
In this particular guide we will assume that you already deposited your ERC20 assets into Binance Exchange.
1) Download the Binance Extension and create a wallet.
Link: Binance Browser Extension
2) Connect to Binance Network and copy your BEP2 address
3) Withdraw the tokens as BEP2 into your new wallet
Make sure to choose the correction network, which in this case is "Binance Chain (BNB)".
4) Once withdrawal is complete, click on "Send"
5) Fill the transaction info, and input your BEP20 address
Your BEP20 address is your BSC address. Just pasting it in will automatically trigger a cross-chain swap, as you can see under "Address" in the screenshot below.
6) Send and confirm the transaction
That's it, that's all there is to it!
You now successfully sent your BNB to your BEP20 address.
This method is the simplest and fastest, but it too has its own disadvantages:
It is the most expensive method, the network fee at the time of writing being $29,78 USD
It does not give you BNB, so you will need to get the BNB for fees from somewhere else/someone else.
We will assume you already downloaded SafePal on your device and connected your already existing wallet to it.
1) In your wallet, click on the "swap" icon
2) Click on the "ETH" icon and pick "ERC20 → BEP20"
3) Choose the values you want to cross-chain swap
Remember that you need to have few ERC20 ETH left to pay for the network fees.
4) Confirm the swap
The deposit address will be automatically chosen and will be the one that matches your SafePal wallet.
5) Wait for the order to complete
6) Congrats, you now have BEP20 ETH
Remember, you'll still need a way to get at least $2.00 USD worth of BNB for fees.
This method is not so different from the Binance Extension method.
In this particular guide we will assume that you already deposited your ERC20 assets into Binance Exchange.
1) Download Trust Wallet on your device and create a wallet
2) Click on "BNB" and copy the address
The "BNB" is BEP2, and the "Smart Chain" is BEP20, a bit confusing.
3) Withdraw the tokens as BEP2 into your new wallet
Make sure to choose the correction network, which in this case is "Binance Chain (BNB)".
4) Once the withdrawal is complete, click on BNB in your wallet, click on the "More" icon and then click on "Swap to Smart Chain"
5) Choose the values of the swap
6) Accept and confirm
7) Congratulations, you now have BEP20 BNB
