Sky Mavis has set May 12, 2026 as the date Ronin will migrate from its standalone chain architecture into a full Ethereum-aligned Layer-2 built on Optimism’s OP Stack, a change the company says will complete Ronin’s “homecoming” to Ethereum and shift the network into a new security and incentive model. The cutover is scheduled to halt block production for about 10 hours, with the team telling users to expect mainnet downtime from 8 a.m. to 6 p.m. Pacific Time, or roughly 11 a.m. to 9 p.m. Eastern Time.
For users and market participants, the immediate issue is operational rather than conceptual. During the migration window, onchain activity will stop, which means token swaps, NFT trades, unstaking and some game-linked interactions will be unavailable until the network comes back online. Sky Mavis has also said games may be paused during the outage, making May 12 a hard execution date for traders, NFT holders, staking participants and builders running production infrastructure on Ronin.
A technical upgrade that also rewrites the economics of RON
The migration is not just a backend move. Ronin is using the switch to Ethereum settlement to overhaul how RON is issued and where network revenue flows, pairing the OP Stack transition with a sharp reduction in inflation and a stronger treasury take from network activity. In its April 22 migration post, Ronin said RON’s inflation rate, currently above 20%, will fall to below 1% after the upgrade, while new treasury inflows will come from the remaining 90 million RON previously set aside for staking, sequencer profits, and a higher marketplace-fee share of 1.25%, up from 0.5%.
That monetary reset sits beside a broader incentive redesign. Proof of Distribution will redirect rewards toward active builders rather than leaving the old validator-era structure intact, with distributions tied to metrics such as gas spend, new users, active users, NFT volume, DEX volume and contract activity. Ronin has been previewing that shift since August 2025, when it first outlined a plan to move from passive validator rewards toward a builder-centric model as part of its Ethereum transition.
The project is also presenting the migration as a performance and security upgrade. Sky Mavis has spent months arguing that the OP Stack move should make Ronin materially faster and more secure, with earlier official materials describing transactions as 12 times faster after the transition and stressing that the network will inherit stronger security and decentralization from Ethereum. A rehearsal for that architecture already took place on February 5, when Ronin’s Saigon Testnet migrated to Ethereum via Optimism in what the team described as an important preparatory step.
Exchanges, stakers and treasury teams now face a hard cutoff
The cleanest signal of near-term execution risk is coming from custody and exchange handling. Coinbase has already warned customers that it will not carry out the RON migration on their behalf, and its support documentation says holders must move tokens to a compatible self-custodial wallet before the project team completes the migration or risk losing access to those assets on the platform. That turns the migration into a practical deadline for treasury desks and token holders who need direct control over their RON during the cutover.
Stakers face a similar decision. Sky Mavis is encouraging users to unstake before May 12, but says any RON still staked when the migration occurs will be automatically unstaked after the network transition is complete. That mechanism reduces the chance of stranded balances, but it also means treasury teams and large holders need to prepare for temporary changes in staking status, reward timing and position availability around the migration window.
The larger significance is that Ronin is attempting two transitions at once: a chain migration and a balance-sheet redesign. If the cutover is smooth, Ronin will emerge as an Ethereum Layer-2 with lower token inflation, new treasury inflows and a more explicit push beyond gaming into a broader application stack. If it is not, the market will remember May 12 less as a technical homecoming than as a test of whether Sky Mavis can coordinate infrastructure, custody and incentive changes without destabilizing the ecosystem it is trying to expand.
