Headline: Ronin sheds sidechain skin — hard fork on May 12 will turn the Axie chain into an Ethereum Layer 2
Ronin, the blockchain best known for powering Axie Infinity and for the $625 million bridge exploit in May 2022, is officially abandoning its standalone sidechain model and re-launching as an Ethereum layer 2. The network will execute a hard fork at block 55,577,490 on May 12, a migration that onchain data and the team say will produce roughly 10 hours of downtime (expected to begin around 15:16 UTC).
Why the shift matters
- Security: Moving to the OP Stack as an L2 tightens Ronin’s link to Ethereum and brings stronger security guarantees compared with an independent sidechain — a meaningful change for a chain that suffered the largest DeFi bridge exploit in history.
- Throughput preserved: Ronin says it will retain high transaction capacity while inheriting Ethereum’s security model and improving data availability via EigenDA.
- Tokenomics and incentives: The migration introduces a “Proof of Distribution” reward model that pays builders for active contributions rather than rewarding passive staking. The team claims this will slash RON inflation from over 20% to below 1%.
What users should expect
- About 10 hours of network downtime: All onchain activity — transfers, swaps, smart contract calls — and games built on Ronin will be paused during the upgrade. Users are urged to complete any necessary transactions or in-game actions before the downtime window.
- Hard fork details: The change occurs at block 55,577,490 and was announced in April; onchain metrics point to a Tuesday start time of ~15:16 UTC.
Economic changes being rolled out
- 90 million RON that were allocated for staking rewards will be redirected into the Ronin Treasury.
- Marketplace fees will rise from 0.5% to 1.25%.
- The new distribution model and fee/treasury changes are intended to reset Ronin’s economic narrative and secure future funding for development.
Market reaction
RON is trading around $0.11 with a market cap near $89.5 million (CoinDesk data). The token has rallied roughly 30% over the past 30 days as investors price in the migration and its implications for supply and inflation dynamics, though prices remain well under 2024 highs.
Background and strategic intent
Ronin’s team framed the move as “plugging back into the mothership,” arguing that the chain — which was originally launched to give Axie Infinity fast, cheap transactions and onboard millions of gamers — has reached a point where tighter integration with Ethereum is the right path forward. The upgrade aims to secure the bridge infrastructure, reset economic levers, and improve scalability and costs for users and builders.
What to watch next
- Whether the downtime and migration proceed smoothly at the announced block height.
- How the Proof of Distribution model performs in practice and whether it meaningfully reduces issuance pressure on RON.
- Community and developer response to higher marketplace fees and the reallocation of staking rewards to the treasury.
- Security outcomes for Ronin’s bridge and ecosystem once L2 security and EigenDA are fully in place.
If you use Ronin, finalize any onchain activity before the planned downtime. For the broader market, this is a high-stakes technical and economic reset that could reshape Ronin’s credibility and token dynamics after its troubled past.
