Ronin Moves to Ethereum Layer 2 Four Years After Hack
Ronin is abandoning its standalone sidechain model in favor of an OP Stack-based Ethereum Layer 2 as blockchain gaming faces mounting pressure and shrinking activity.
The Ronin blockchain, originally launched by Sky Mavis to support the explosive growth of Axie Infinity, is set to complete a major architectural shift on May 12 by migrating from an independent Ethereum sidechain to an OP Stack-powered Layer 2 network.
The transition marks one of the most significant upgrades in Ronin’s history, moving the gaming-focused network closer to Ethereum’s expanding Layer 2 ecosystem nearly four years after the platform suffered a record-breaking exploit tied to North Korea’s Lazarus Group.
According to the network, the migration will be carried out through a hard fork, temporarily pausing all network activity, including token transfers, swaps, smart contract interactions, and in-game actions across titles built on Ronin.
Ronin Reconnects With Ethereum
Sky Mavis introduced Ronin in 2021 as an EVM-compatible blockchain designed specifically for blockchain gaming. At the time, Ethereum’s scaling ecosystem was still in its infancy, prompting the company to develop a dedicated sidechain capable of supporting high transaction throughput and low fees for play-to-earn gaming.
Now, Ronin says the environment has changed dramatically.
“The time has come to plug Ronin back into the mothership: Ethereum,” Ronin stated in an announcement published on X.
The team added that Ethereum Layer 2 infrastructure has matured substantially since Ronin’s launch.
“In 2020, when we announced Ronin, Ethereum’s Layer 2 landscape was only an idea. The cost of data availability and settlement costs were also high. Today, Ethereum’s Layer 2s are battle-tested, and OP Stack powers millions of transactions every day.”
The migration places Ronin alongside a growing list of networks adopting the OP Stack, the modular framework developed within the Optimism ecosystem. The same technology stack underpins major Ethereum scaling networks including Base and Optimism.
Major Tokenomics Changes Incoming
Beyond infrastructure improvements, the upgrade will also introduce sweeping tokenomics changes for the Ronin ecosystem.
Most notably, the network said the annual inflation rate of the RON token will fall from above 20% to below 1%, representing a dramatic reduction in new token issuance.
The move could help stabilize the ecosystem’s long-term economic model at a time when many blockchain gaming projects continue to struggle with declining user activity and weakened token performance.
Ronin has processed billions of dollars in NFT trading volume since launch and became one of the most recognized gaming-focused blockchains during the peak of the play-to-earn boom.
However, the network’s rapid rise was followed by one of the most damaging security incidents in crypto history.
The 2022 Hack Still Defines Ronin’s Legacy
In March 2022, attackers compromised Ronin validators and drained roughly $625 million worth of ETH and USDC from the network’s bridge infrastructure.
The exploit quickly became one of the largest cross-chain bridge hacks ever recorded in decentralized finance. U.S. authorities later attributed the attack to North Korea’s Lazarus Group.
The fallout forced Sky Mavis into emergency recovery efforts. The company raised $150 million from Binance and other investors to reimburse affected users and replace compromised validators across the network.
Investigators later managed to recover portions of the stolen assets. Chainalysis and U.S. law enforcement helped trace and retrieve approximately $30 million, while Norwegian authorities returned an additional $5.7 million in 2024.
The upcoming migration therefore represents more than a technical upgrade — it also signals Ronin’s attempt to reposition itself within a more mature and security-conscious Ethereum ecosystem.
Blockchain Gaming Faces a Harsh Reality
Ronin’s transition comes during a difficult period for the broader Web3 gaming industry.
According to an April 2026 analysis by Caladan, an estimated 93% of Web3 gaming and GameFi projects launched since 2020 are now effectively inactive. The report classified projects as defunct when token prices had fallen more than 90% from peak levels alongside near-zero daily active users.
The sector reportedly attracted between $12 billion and $15 billion in capital from 2020 through early 2026. Despite that massive inflow, gaming-related crypto assets have plunged roughly 95% from their 2022 highs, while venture capital funding for blockchain gaming studios has reportedly collapsed by around 93% over the same period.
Even Axie Infinity, once the defining success story of blockchain gaming, has experienced a steep decline in activity. Reports suggest the game’s daily active users have fallen by more than 90% from peak levels reached during the play-to-earn frenzy.
OP Stack Adoption Continues Expanding
Despite the slowdown in GameFi, infrastructure development around Ethereum Layer 2 networks continues to accelerate.
The OP Stack has emerged as one of the dominant frameworks for launching scalable Ethereum-compatible chains, with more than 32 Layer 2 networks reportedly operating in production using the technology.
Several exchanges and ecosystems have already adopted the framework to launch custom blockchains. As reported earlier, South Korea-based crypto exchange Upbit partnered with the Optimism Foundation to build the OP Stack-powered GIWA Chain.
Ronin now joins that growing ecosystem as blockchain developers increasingly favor modular Ethereum scaling solutions over standalone sidechains.
For Ronin, the migration represents a strategic reset — one aimed at strengthening security, reducing inflation, and reconnecting with Ethereum’s broader infrastructure at a time when blockchain gaming is searching for a sustainable path forward.
