Ethereum <> BNB chain
BRIDGING GUIDE
In this document, we will explain how to bridge between Ethereum Mainnet and BNB Chain.
Preparation Phase
For bridging, the chains you will bridge in your wallet must be set up. In EVM-based wallets (such as Metamask), Ethereum is already set up by default. If you don't have the BNB Chain network in your wallet, you need to set it up first.
IMPORTANT NOTICE
If you wish to bridge your EQB / ePENDLE from the Arbitrum One network to BNB Smart Chain directly, it is not possible. You must first bridge them from the Arbitrum One network to the Ethereum Mainnet (via https://bridge.arbitrum.io/ Tutorial), and then from the Ethereum Mainnet to BNB Smart Chain (keep reading this guide)
Phase 1
Add BNB Smart Chain (BSC) to MetaMask Manually
Open the drop-down menu by clicking on the Ethereum Mainnet display. Then click “Add network”.
Now click on “Add a network manually”.
On the “Add a network manually” page that opens, you'll need to add the following details. Click “Save” when you're done.
Network Name: BNB Smart Chain
New RPC URL: https://bsc-dataseed.binance.org/
Chain ID: 56
Currency Symbol: BNB
Block Explorer URL: https://bscscan.com
Or you can use ChainList to add new network. By visiting the link below, you can automatically add the "BNB Smart Chain (BSC) One" network to your wallet.

Phase 2
You need to have the contract addresses of the tokens you want to bridge. Ethereum and BNB Smart Chain (BSC) contract addresses for EQB and ePendle are as follows:
Ethereum Mainnet:
EQB: 0xfE80D611c6403f70e5B1b9B722D2B3510B740B2B
ePendle: 0x22Fc5A29bd3d6CCe19a06f844019fd506fCe4455
BNB Smart Chain (BSC):
EQB: 0x374Ca32fd7934c5d43240E1e73fa9B2283468609
ePendle: 0x5fec857958FBDe28e45F779DAf5aBa8FDd5bD6BC
Once you have added the chains and tokens to your wallet, your wallet should look like this for the Ethereum and BNB Smart Chain (BSC) One networks:
Bridging from Ethereum Mainnet to BNB Smart Chain (BSC)
In this phase, we will bridge the EQB token from Ethereum Mainnet to BNB Smart Chain (BSC).
Step 1 - Switch to the Ethereum network in your wallet. Please go to https://www.portalbridge.com/
Step 2 - Select Ethereum on the "From" section.
Step 3 - Select Binance Smart Chain (BSC) One on the "Target" section.
Step 4 - Please click “Connect” and approve on wallet.
Step 5 - Paste the EQB (Ethereum) contract address that we shared above into the “Select A Token > Search name or paste address” section.
Your transaction will appear like this before confirmation:
Step 6 - Then click on the "Next" button and confirm the network switching on your wallet.
Portal Bridge (Wormhole) will automatically transfer you to the BNB Chain. After the transition, you will see this screen.
Step 7 - Proceed with the process by clicking the 'Next' button. At this stage, your wallet will switch back to the Ethereum Mainnet. Afterward, you will need to approve spending for the EQB token in your wallet. You can either approve with the 'Default' option for the default amount or set a custom value. If you grant approval for a specific amount, you will need to provide approval again for higher amounts in future bridge transactions.
Step 8 - Once the spending approval is granted, you are now ready for the transfer process. You can initiate the bridging by clicking the "TRANSFER" button.
Step 9 - This pop-up shows you a summary of the transaction you are about to perform. Please review it again, and when you are certain there are no errors or omissions, click the "CONFIRM" button. Then, proceed with the final confirmation on your wallet.
Step 10 - The bridging process will begin after wallet confirmation. The bridging takes approximately 15 minutes. During this time, you will see the following screen on your device:
Step 11 - When your transaction is completed, you will encounter a screen similar to the one below. At this stage, you should click the "REDEEM" button and approve the transaction on your wallet. This will allow you to receive the bridged token in your wallet on the BNB Smart Chain.
Now you have successfully transferred the EQB token from Ethereum to the BNB Smart Chain (BSC) network, and you can switch to the BNB Smart Chain (BSC) network in your wallet to see the EQB token.
If you want to bridge ePendle, you can follow all these steps in the same order. All you need to do is paste the ePendle / Ethereum contract address into the token list under the "From" section in Step 5
Bridging from BNB Smart Chain (BSC) to Ethereum Mainnet
In this phase, we will bridge the EQB token from Ethereum Mainnet to BNB Smart Chain (BSC).
Step 1 - Switch to the BNB Smart Chain network in your wallet. Please go to https://www.portalbridge.com/
Step 2 - Select BNB Smart Chain network on the "From" section.
Step 3 - Select Ethereum on the "Target" section.
Step 4 - Please click “Connect” and approve on wallet.
Step 5 - Paste the EQB (BNB Smart Chain) contract address that we shared above into the “Select A Token > Search name or paste address” section.
Your transaction will appear like this before confirmation:
Step 6 - Then click on the "Next" button and confirm the network switching on your wallet.
Portal Bridge (Wormhole) will automatically transfer you to the Ethereum. After the transition, you will see this screen.
Step 7 - Proceed with the process by clicking the 'Next' button. At this stage, your wallet will switch back to the BNB Smart Chain. Afterward, you will need to approve spending for the EQB token in your wallet. You can either approve with the 'Default' option for the default amount or set a custom value. If you grant approval for a specific amount, you will need to provide approval again for higher amounts in future bridge transactions.
Step 8 - Once the spending approval is granted, you are now ready for the transfer process. You can initiate the bridging by clicking the "TRANSFER" button.
Step 9 - This pop-up shows you a summary of the transaction you are about to perform. Please review it again, and when you are certain there are no errors or omissions, click the "CONFIRM" button. Then, approve the transaction on your wallet.
Step 10 - The bridging process will begin after wallet confirmation. The bridging takes approximately 5 minutes. During this time, you will see the following screen on your device:
Step 11 - When your transaction is completed, you will encounter a screen similar to the one below. At this stage, you should click the "REDEEM" button and approve the transaction on your wallet. This will allow you to receive the bridged token in your wallet on the Ethereum Mainnet.
Now you have successfully transferred the EQB token from BNB Smart Chain (BSC) to the Ethereum Mainnet, and you can switch to the Ethereum Mainnet network in your wallet to see the EQB token.
If you want to bridge ePendle, you can follow all these steps in the same order. All you need to do is paste the ePendle / BNB Smart Chain (BSC) into the token list under the "From" section in Step 5.
