Immutable Chain plans to upgrade to an OP Stack chain in 202
On November 6, 2026, Immutable posted on X that Immutable Chain will upgrade from a custom geth fork to an OP Stack-based chain in 2027. After the upgrade, transactions will be faster and the chain will have a closer tie to Ethereum's security; all accounts, balances and contracts will migrate automatically, and almost all users will not need to take any action.

Background and Impact
On November 6, 2026, both PANews and Odaily Planet Daily reported at 05:22 that Immutable posted on X that Immutable Chain will upgrade to an OP Stack-based chain, scheduled for 2027, starting from the current "custom geth fork." The two sources differ slightly in how they phrase the timing: PANews quoted it as "will upgrade in 2027," while Odaily Planet Daily wrote "plans to upgrade in 2027" — the former is more definitive in tone, while the latter emphasizes that this remains a plan. Neither gave a specific date within 2027, nor did they explain the specific switching process.
Immutable Chain currently runs a custom geth fork, which is the direct background for this upgrade. According to Immutable, after switching to an OP Stack-based chain, on-chain transactions will be faster and the chain will establish a closer link to Ethereum's security. OP Stack appears here only as the name of the upgrade target; neither source disclosed specific performance improvement figures, whether fees will change, or related arrangements for sequencers, validators and the like.
For existing users, the most directly relevant information is how the migration works: all accounts, balances and contracts will migrate automatically, and almost all users will not need to take any action (Odaily phrased it as "no action needed"). Neither source mentioned any need to manually claim, swap or re-authorize, nor did they mention any change in the form of assets. The relevant content was published by Immutable's official X account, and specific details are subject to subsequent official announcements. It should be noted that search demands such as Huobi HTX app registration and download, Zhima Gate.io app registration and download, Bitget app registration and download, Binance app registration and download, and OKX app registration and download are not directly related to this chain upgrade; based on the available information, the migration is completed automatically at the chain level and does not involve additional operations through exchanges.
The parts not yet disclosed are also worth noting. Neither source explained the specific schedule within 2027, whether block production will be paused during the migration window, how bridges and ecosystem applications will adapt, or whether adjustments to the token or incentive structure are involved. These gaps mean that several points remain to be filled in by official announcements, and only then will it be possible to judge the actual impact of the upgrade on applications and capital flows within the Immutable ecosystem.
