Introduction
Kolex is migrating from Immutable X to Immutable zkEVM to improve scalability and enable greater interoperability with other Web3 games and ecosystems. Below, we’ve outlined answers to common questions about the migration, from overall timelines to technical specifics.
The migration date is set to begin on September 30th, 2025.
Migration Overview
Q: What is the reason behind the migration to zkEVM?
A: The migration to Immutable zkEVM is intended to future-proof Kolex, ensuring scalability and unlocking advanced smart contract capabilities. It also positions our ecosystem within a broader Web3 gaming ecosystem, fostering potential interoperability and delivering an improved experience for all collectors.
Q: What will happen to assets/cards during the migration?
A: All Immutable X assets will be migrated automatically to Immutable zkEVM by default.
Q: What is the ETA for the migration?
A: Migration date is set for September 30th, 2025. At this time assets will be locked and cannot be moved until they are migrated. Migration is expected to take up to four weeks.
Technical & Fees
Q: Will I still be able to bridge my assets to Ethereum?
A: Bridging to Ethereum is no longer supported by IMX with zkEVM. Any Kolex NFTs that have been withdrawn to Ethereum L1 will not be migrated to Immutable zkEVM. They will continue to exist on Ethereum L1.
If you wish to move your NFT’s to Ethereum L1, it must be done by September 30, 2025.
Q: What will the transaction fees be on zkEVM?
A: A small gas fee per transaction in $IMX will be required when using MetaMask or any EOA (Externally Owned Account). Transactions made with Passport will offer a gas-free experience.
Q: Will there be gas fees for every transaction?
A: For every transaction using an EOA wallet, users must pay a small gas fee in $IMX. In the future, users with Passport accounts will enjoy a gas-free experience for transactions.
Q: Will the migration allow adding new metadata to cards (e.g., first mints)?
A: NFTs will retain the same metadata after migration, including the same tokenID and Proto.
Asset & Wallet Management
Q: How will assets be migrated?
A: All assets will be migrated to the same wallet they currently reside in.
Q: What happens to tokens (ETH, IMX, USD) already on Immutable X? Will they move to Immutable zkEVM automatically based on the wallet’s balance?
A: Not at this stage. Users must manually bridge these tokens.
Q: Will all assets be moved to the Passport wallet or stay in their original wallets?
A: All assets will be migrated to the same wallet they’re currently in.
Q: If assets will be moved to Passport by default, can collectors opt out and have them on an EOA?
A: No assets will be placed in a different wallet unless the user actively moves them there before migration. Passport wallets will not be available in the first migration phase.
User Experience & Support
Q: How will user support be handled during and after migration?
A: Our team will remain active in Discord and through our standard customer support channels to assist with any migration-related questions or issues.
Q: Will there be additional Web2 features available through Google and Apple stores?
A: We frequently receive requests for additional Web2 integrations and will factor these into our future plans.
