move.mantrachain.io is the official interface for moving OM between MANTRA’s Cosmos environment (your Keplr/Leap wallet) and MANTRA’s EVM environment (your MetaMask/Rabby wallet).
Move OM now: Visit move.mantrachain.io.

​
What you’re actually moving

  • Cosmos side: native OM (Cosmos SDK coin, commonly shown as OM / uom)
  • EVM side: OM’s ERC-20 representation on MANTRA EVM (commonly shown as wOM)
You can confirm the canonical wOM contract addresses here: Canonical ERC-20 Contracts.

​
Prerequisites

  • A Cosmos wallet (Keplr or Leap) connected to MANTRA Chain
  • An EVM wallet (MetaMask, Rabby, etc.) configured for MANTRA Chain
  • A small amount of OM available for network fees
If you need RPCs/chain IDs/explorers for setup, see: Network Details.

​
Cosmos → EVM (receive wOM in your EVM wallet)

  1. Open move.mantrachain.io
  2. Connect your Cosmos wallet (Keplr/Leap)
  3. Connect your EVM wallet (MetaMask/Rabby)
  4. Choose the direction Cosmos → EVM
  5. Enter the amount of OM to move
  6. Review the destination address and amounts shown in the UI
  7. Confirm the transactions in your wallets
After completion, your EVM wallet balance should reflect the moved amount as wOM.

EVM → Cosmos (receive native OM in your Cosmos wallet)

  1. Open move.mantrachain.io
  2. Connect your EVM wallet (MetaMask/Rabby)
  3. Connect your Cosmos wallet (Keplr/Leap)
  4. Choose the direction EVM → Cosmos

  6. Review the destination address and amounts shown in the UI
  7. Confirm the transactions in your wallets
After completion, your Cosmos wallet balance should reflect the moved amount as OM.

Troubleshooting

  • Wrong network: Ensure your wallets are on the correct MANTRA network (Mainnet vs Dukong Testnet). See Network Details.
  • Can’t see wOM: Check the canonical contract address and add/import the token in your EVM wallet. See Canonical ERC-20 Contracts.
  • Tx succeeded but balance hasn’t updated: Verify the transaction on an explorer (links are in Network Details).
Always double-check wallet addresses and network selection before confirming transactions. Blockchain transactions are typically irreversible.
