Ronin Ethereum is migrating to a Layer 2 on Might 12 with roughly 10 hours of scheduled downtime.
Abstract
- Ronin will exhausting fork at block 55,577,490 on Might 12, transitioning from an unbiased sidechain to an Ethereum Layer 2 on the OP Stack.
- All transfers, swaps, and sensible contract interactions will pause for roughly 10 hours throughout the migration window.
- RON token inflation will drop from over 20% to under 1%, with 90 million RON redirected to the treasury as market charges rise to 1.25%.
Ronin, the gaming-focused blockchain behind Axie Infinity, is executing a tough fork on Might 12 to finish its transition from an unbiased sidechain to an Ethereum Layer 2. The migration was introduced in April and can set off at block 55,577,490, anticipated round 15:16 UTC.
All Ronin transactions will pause for roughly 10 hours throughout the migration window. That covers transfers, swaps, NFT trades, and sensible contract interactions. Node operators on Ronin mainnet are required to improve to launch 1.2.2 earlier than the exhausting fork.
What adjustments after the migration
Ronin mentioned the transfer is about plugging “again into the mothership.” The brand new construction will hyperlink the community on to Ethereum for settlement and knowledge availability, changing the older nine-validator sidechain mannequin with OP Stack rollup infrastructure.
RON token inflation will fall sharply from over 20% yearly to under 1% beneath a brand new Proof of Distribution mannequin. Market charges can even rise from 0.5% to 1.25%, with 90 million RON tokens beforehand allotted for staking redirected to the Ronin treasury.
Ronin will combine EigenDA to deal with knowledge availability for transactions, storing knowledge off-chain whereas maintaining it verifiable and accessible to Ethereum. The migration brings Ronin into the identical OP Stack ecosystem as different chains together with Celo and Fraxtal.
Context: the $625 million hack that made this obligatory
Whereas working as an unbiased sidechain in March 2022, Ronin suffered the most important DeFi bridge exploit in historical past, with $625 million in ETH and USDC drained from its bridge. The assault uncovered the structural dangers of the sidechain mannequin, the place solely a small variety of centrally-managed validators have been chargeable for securing the community.
The Layer 2 transition straight addresses these issues by inheriting Ethereum’s safety quite than counting on Ronin’s personal validator set. The Ronin bridge beforehand migrated to Chainlink’s cross-chain interoperability protocol in April 2025 as an earlier step in securing its infrastructure forward of the complete L2 transfer.
