In order to participate in Marinade's governance and benefit from MNDE's utility, you will need to lock it in Realms to obtain veMNDE. Unlocking your tokens to get back your MNDE will start a 30-day unlock process.
When locking your MNDE, make sure to choose the following settings:
Realms offer two options, "Deposit" and "Lock tokens". Make sure to only use "Lock tokens" as depositing tokens will not give you any voting power in Marinade governance.
If you owned Marinade NFTs containing locked MNDE, a migration tool is available on Marinade's dApp.
Once your wallet has locked MNDE tokens in Realms, you can use your veMNDE power to vote on proposals.
