OM Migration Tool User Guide

How to Use the OM Migration Tool: Go to mantra.zone/migrate

Step 1: Prepare Your Wallets

1. EVM-Compatible Wallet: Ensure you have an EVM-compatible wallet (i.e. MetaMask or Rabby) connected to the Ethereum network to send your OMv2 ERC20 tokens from.

2. MANTRA Chain Wallet: Create or ensure you have access to a MANTRA Chain Cosmos-enabled wallet (i.e. Keplr setup here) where you'll receive your new OMv3 tokens on MANTRA Chain.

Step 2: Connect Your Wallets

• Open the OM Migration Tool interface.

• Select your EVM-compatible wallet and connect it.

Step 3: Initiate Migration

1. Enter Amount: Specify how many tokens you'd like to transfer (you can migrate any amount).

2. Confirm Transaction: Review your transaction details, accept the terms of use, and confirm.

OM Migration Tool 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 OM Migration Tool 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.

OM Migration Tool UI: This example shows a table of multiple OM migration orders from the connected EVM-compatible wallet to various MANTRA Chain wallets. Users may view details of their migrate order by clicking on the linked-icon image below the Details column of the table. Please note: • The table displays all valid OM migration 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 OM migration transaction solely.

OM Migration Tool UI: An example of a OM migration 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 OM Migration Tool offers a simple and efficient way to migrate your ERC20 OM tokens from Ethereum to our MANTRA Chain. Happy migrating! 🚀
