Ronin Migrates to OP Stack Layer 2 on May 12 With 10-Hour Downtime; RON Inflation Cut From 20% to Below 1%

According to The Block, Ronin, the gaming blockchain developed by Sky Mavis, will migrate from an independent Ethereum sidechain to an OP Stack-based Layer 2 network on May 12, with approximately 10 hours of scheduled downtime during which all network transactions and onchain game actions will pause.

The upgrade will cut RON’s annual inflation rate from above 20% to below 1%. The migration, executed via hard fork, moves Ronin away from the independent sidechain model it has operated since 2021 to an Ethereum Layer 2 using the same framework underlying Base and Optimism. The upgrade arrives four years after Ronin’s March 2022 bridge exploit that drained roughly $625 million in ETH and USDC, attributed to North Korea’s Lazarus Group.
