Ronin set to transition to Ethereum layer 2 from independent sidechain

The purpose behind the migration is to enhance security, tokenomics and scalability, said Ronin, which suffered the largest DeFi bridge exploit on record in 2022.

What to know:

• Ronin, the gaming-focused blockchain behind Axie Infinity, will hard fork on May 12 to migrate from an independent sidechain to an Ethereum layer 2, causing about 10 hours of network downtime.
• During the migration window, all Ronin transactions and onchain game actions will be paused.
• The transition to the OP Stack and a new Proof of Distribution model will sharply cut RON token inflation and aim to improve security, scalability and costs after the network’s history-making $625 million bridge exploit.

Ronin, the gaming-centric blockchain once synonymous with the industry’s infamous $625 million exploit, is officially shedding its sidechain skin on May 12 to become an Ethereum layer 2 to improve security while maintaining throughput.

Ronin, which announced the migration in April, will execute a hard fork at block 55,577,490, a process that will result in about 10 hours of downtime for users, the network said Monday on X. According to onchain data, the migration is expected to begin on Tuesday around 15:16 UTC.

“Four years ago, we launched Ronin because Axie Infinity needed a faster and more efficient network,” Ronin said when announcing the migration. “It worked. Axie Infinity onboarded millions of gamers to crypto, and Pixels proved that it was possible to do it again.” The time has come to plug "back into the mothership."

While operating as an independent sidechain in mid-May 2022, Ronin suffered what is still today the largest DeFI bridge exploit in history. Layer 2 protocols benefit from tighter links to the underlying blockchain than sidechains, offering benefits that include greater security.

The network's native token, RON, is currently trading at around 11 cents with a market capitalization of about $89.5 million, according to CoinDesk data. While the token remains significantly below its 2024 peak, the migration sparked a rally, with prices climbing 30% over the last 30 days as investors eye a shift in the network's supply dynamics.

“During this downtime window, all network transactions [including transfers, swaps, and smart contract interactions] will be paused,” Ronin said, adding that all games using its network will also be affected. “To avoid any inconvenience, please complete all necessary transactions/onchain game actions on the Ronin Network before the downtime begins.”

During the downtime, a "Proof of Distribution" model will be introduced to reward builders based on active network contribution rather than passive staking, Ronin said. The team noted that “this is fundamentally bullish for RON as it dramatically cuts token inflation from over 20% to below 1%.”

The company also said that transitioning to the OP Stack will allow it to inherit Ethereum’s robust security while maintaining high throughput. The move redirects 90 million RON tokens previously earmarked for staking rewards into the Ronin Treasury, while more than doubling marketplace fees to 1.25% from 0.5%.

Ronin said its narrative is dominated by its pivotal return to Ethereum, a strategic move to reset its economics, secure its bridge infrastructure, and secure its future in an upgrade intended to improve scalability and reduce costs through the use of EigenDA for data availability.

What to know:

• LayerZero acknowledged it “made a mistake” by allowing its own verifier network to secure high-value assets in a risky configuration, reversing weeks of blaming Kelp DAO for a $292 million hack tied to North Korean attackers.
