Immutable Chain to Transition to OP Stack Rollup on Ethereum by 2027
Written with artificial intelligence.
Immutable is planning a significant overhaul of Immutable Chain, transitioning to an OP Stack rollup on Ethereum with a target completion date in mid-2027. This upgrade aims to reduce block times to 1 second, enhancing transaction speed, although costs may rise slightly and native withdrawal times will extend to approximately 7 days.
Immutable Chain Overhaul
Immutable is reworking the internals of Immutable Chain, the network supporting its games, by transitioning to an OP Stack rollup on Ethereum. This upgrade is expected to allow block production every second, a notable decrease from the current two-second interval. The switch is planned for mid-2027.
Impact on Transactions and Withdrawals
With the reduced block time, players can expect quicker confirmations for on-chain actions. However, Immutable has indicated that transaction costs may see a slight increase post-migration. Currently, gas fees on Immutable Chain are described as extremely low.
Native asset withdrawals will experience delays, taking around 7 days to complete. Immutable anticipates that most bridging activities will continue to utilize faster liquidity bridges during this transition.
Migration Details
During the migration process, block production will halt for several hours, and Immutable will provide prior notice of the exact date. The existing native bridge, which currently operates on Axelar, will transition to utilize state commitments posted on Ethereum for withdrawal verifications.
Initially, the network will implement permissioned fault proofs, with plans to incorporate zk-validity proofs later. This upgrade will also facilitate faster protocol and EVM upgrades.
Testnet Deprecation
Furthermore, by the end of 2026, Immutable will discontinue its current public testnet for game usage, citing it as ineffective for testing complex game flows. Developers are encouraged to consult Immutable’s documentation for necessary modifications and are assured support from account managers during this transition.
As Immutable shifts its infrastructure, the focus will be on enhancing performance and scalability within the OP ecosystem.
