How to Use the MANTRA Bridge: Go to mantra.zone/bridge

Step 1: Prepare Your Wallets

1. EVM-Compatible Wallet: Ensure you have an EVM-compatible wallet (i.e. MetaMask) connected to the Ethereum network.

2. MANTRA Chain Wallet: Create or ensure you have access to your MANTRA Chain wallet (i.e. Leap Wallet, Keplr etc.) where you'll receive your new tokens.

Step 2: Connect Your Wallets

• Open the MANTRA Bridge interface.

• Select your EVM-compatible wallet and connect it.

Bridge UI: The modal confirmation that activates when the user has clicked on the “Place order” button. Linked pages: • Terms of Use • Privacy Policy

Bridge UI: Upon the user accepting terms and clicking on the “Continue” button, they will receive a pop-up from their EVM-compatible wallet asking them to confirm their transaction. Please note that the above screenshot is a mockup only. The particular EVM-compatible wallet pop-up will vary per user.

Step 4: Monitor Your Migration

• Once submitted, our system will automatically verify your Bridge transaction on the Ethereum network.

• This process ensures that your transaction includes:

  • The correct contract address for your ERC20 OM tokens.

  • The Ethereum burn address.

  • A valid MANTRA Chain wallet address for receiving your new tokens.

Bridge UI: This example shows a table of multiple Bridge orders from the connected EVM-compatible wallet to various MANTRA Chain wallets. Users may view details of their Bridge order by clicking on the linked-icon image below the Details column of the table. Please note: • The table displays all valid Bridge orders from the connected EVM-compatible wallet regardless if the MANTRA Chain wallet is connected or not. • Connecting your MANTRA Chain wallet allows you to create a new Bridge transaction solely.

Bridge UI: An example of a Bridge order is shown above. This pop-up is displayed by clicking on the linked-icon image below the Details column of the table.

Step 5: Receive Your MANTRA Chain Tokens

• You will receive an equivalent amount of MANTRA Chain tokens once the transaction has been verified by our system.

Conclusion

The Bridge offers a simple and efficient way to migrate your ERC20 OM tokens from Ethereum to our MANTRA Chain. Happy migrating! 🚀
