1. Use Binance Bridge of BSC to cross-chain assets

This version is suitable for crossing the assets of the Binance Smart Chain to other chains, or crossing the assets of other chains (except the Ethereum) to the Binance Smart Chain. However, BNB(BEP-2)and BNB(BEP-20)cannot be cross-chained in Binance Bridge. It is recommended to transfer in Binance Exchange for operation.

1) Open the dApp of Binance Bridge

  • Click on the "Discover" page

  • Search Binance Bridge(BSC)

  • Click "Confirm" in the disclaimer pop-up window to enter the dApp

2) Connect wallet

  • Click "Connect Wallet"

  • Select "MetaMask" and click "Connect Wallet"

If you choose MetaMask, you can also accurately connect to the BSC address in ONTO.

3) Cross-chain the ONT(OEP-4)in the Ontology to the ONT(BEP-20)of the Binance Smart Chain

  • Select ONT in Assets

  • Select the corresponding blockchain network: ONT Network——Binance Smart Chain Network

  • Enter the number of assets that need to be cross-chain

  • Click "Next"

  • Select the cross-chain transaction method(it is recommended to select "l will send tokens from my own wallet" and then transfer assets from the ONTO wallet)

  • Click "Confirm"

4）Send the assets of the Ontology to the address specified by Binance Bridge

  • Save the QR code or copy the address

  • Go back to the ONTO wallet and enter the ONT asset page

  • Click "Send"

  • Paste the address specified by Binance Bridge

  • Enter the number of assets that need to be cross-chain, and click "Next"

  • Enter the password, click "Complete" and return to Binance Bridge

5）Waiting for the cross-chain assets to arrive

  • When the Confirmations page shows the "✔️" symbol indicating that the transfer is completed, the cross-chain transfer can be completed

  • Go back to the Assets Page of ONTO and check whether the ONT(BEP_20)has arrived

The ONT(BEP-20)needs to be manually added on the ONTO Assets Page

  • Click "+" on the asset page, enter and search for ONT

  • Find the corresponding ONT under the BSC and click "+" on the right to see the ONT on the Asset Page. Click to enter the asset details page and click "Receive" to view the wallet address.

6）Cross-chain ONT(BEP-20)in Binance Smart Chain to ONT(OEP-4)in Ontology

  • Select ONT in Assets

  • Select the corresponding blockchain network: Binance Smart Chain Network——ONT Network

  • Enter the number of assets that need to be cross-chain

  • Back to the ONTO Assets page, click to enter the ONT asset details page -> click "Receive" to view and copy the ONT address

  • Go back to Binance Bridge and paste the copied ONT address at “Destination” as the assets receiving address

  • Click "Next"-"Confirm"

  • Copy the address and return to the ONTO Asset Page

  • Enter the ONT (BEP-20) asset details page -> click "send", paste the copied address and enter the number of assets that need to be cross-chain

  • Click "Next step" and enter the password in the pop-up window to complete the transfer

  • After the transfer is completed, click "Submit transaction via Metamask", click "Confirm" in the pop-up box and enter the password to complete the asset cross-chain

Using Binance Bridge to transfer assets from the Binance Smart Chain to the Ontology will charge 1 ONT as a Network fee, so the actual assets received will be reduced by 1 ONT on the basis of Metamask transfer.

7）Waiting for the cross-chain assets to arrive

  • When the Confirmations page shows the "✔️" symbol indicating that the transfer is completed, the cross-chain transfer can be completed

  • Go back to the Asset Page of ONTO and check whether the ONT on the Ontology has arrived

  • Find the corresponding ETH under the BSC and click "+" on the right to see the ETH_BEP20 on the Asset Page. Click to enter the asset details page and click "Receive" to view the wallet address.
