Ronin Pulls the Switch: Ethereum L2 Migration Goes Live May 12

Ronin's Ethereum L2 migration started on May 12, 2026, with the team posting that the cutover had begun and projecting about 10 hours of network downtime
The hard fork triggered at block height 55,577,490, ending Ronin's run as a standalone sidechain
Ronin posted a follow-up status on May 13 confirming the teams were finalizing the rollout with a smooth completion imminent
All on-chain activity, including transfers, swaps, NFT trades, and unstaking, was paused during the downtime window
RON annual inflation drops from over 20% to under 1% post-migration, with 90 million RON moved into the treasury
Marketplace fees increase from 0.5% to 1.25%, with the additional revenue flowing to the treasury
The new Proof of Distribution program automatically rewards builders monthly based on gas spend, user acquisition, NFT and DEX volume, and smart contract activity
Node operators were required to upgrade to release 1.2.2 before the hard fork block to stay on the canonical chain

Ronin Network, the chain that has powered Axie Infinity, Pixels, and the rest of the Sky Mavis gaming ecosystem since 2021, has executed its long-anticipated migration from an independent EVM sidechain to a full Ethereum Layer 2. "Ronin's migration to Ethereum has begun," the team posted on May 12, projecting about 10 hours of downtime "from the time of this post" before declaring the network would be "home." source The hard fork triggered at block height 55,577,490, ending four years of life as a standalone sidechain.

What Actually Changed

The migration is a hard fork, not a soft upgrade. Ronin is now an Ethereum Layer 2 built on Optimism's OP Stack rather than an independent EVM chain operated by Sky Mavis-controlled validators. The shift inherits Ethereum's security model through the standard L2 fraud proof and settlement design, replacing the sidechain bridge model that has historically been Ronin's biggest security liability.

Ronin transitioned at block height 55,577,490 from being an independent EVM sidechain into a full Ethereum Layer 2 built on Optimism's OP Stack on May 12, with a roughly 10 hour planned hibernation period. source All on-chain activity, including transfers, swaps, NFT trades, and unstaking, was paused during that window.

The team confirmed the rollout was nearing completion early on May 13. "Ronin and Ethereum Migration Update. We're almost home. Our teams are making sure everything is running as smooth as possible," the team posted, signaling that the rollout was in the final integration phase. source

Worth Noting

Worth noting: Hard forks at this scale are rare in production gaming chains. Most L1 to L2 transitions ship as new chains running alongside the legacy network, with bridge contracts handling user migration. Ronin chose the harder path of a full cutover so that the existing app surface, including Axie, Pixels, Lumiterra, and the marketplaces, would land directly on the new infrastructure without a bridge migration step.

The Economic Reset That Comes With It

The most consequential part of the migration for RON holders is not technical, it is economic. RON's annual inflation drops from over 20% to under 1% post-migration, and 90 million RON that was previously reserved for staking rewards moves into the treasury alongside net sequencer profits and increased marketplace revenue. source

That is a dramatic compression. A token that has been emitting more than 20% in new supply every year now becomes nearly fixed supply. Combined with the marketplace fee increase from 0.5% to 1.25%, the treasury gains three new revenue streams while the token economy stops bleeding fresh supply into the market.

The 2.5x marketplace fee hike is the part players will feel immediately. NFT sellers on the Ronin Marketplace now keep less of each sale, with the difference flowing to the treasury rather than to liquidity providers or the protocol's previous fee distribution structure.

Proof of Distribution: Who Gets Paid

The migration introduces a new builder incentive program called Proof of Distribution. Rather than negotiating one-off grants and partnerships, Ronin now runs a monthly distribution to builders calculated from on-chain merit scores.

The published weighting is roughly:

Gas spending: 18.13%
User acquisition and engagement: about 24%
NFT and DEX volume: about 41%
Smart contract activity: 16.37%

Developers have to register their contracts at the Proof of Distribution portal to qualify. Projects that drive real on-chain activity will see the largest payouts, which is a meaningful shift from the typical model where smaller projects compete for marketing budget allocation from chain teams.

Tip

Tip: If you operate a contract on Ronin and are not registered for Proof of Distribution, you are leaving recurring monthly RON on the table. The registration step is small but the payout is real ongoing yield calibrated to how much activity your project actually generates.

What This Means for Axie, Pixels, and the Rest of the Ecosystem

For Axie Infinity, Pixels, and the rest of the games sitting on Ronin, the migration changes the underlying security and economics but should be invisible at the gameplay level. Players still log in, hold the same NFTs in the same wallets, and pay roughly the same transaction costs.

The bigger impact is upstream. Ethereum's security guarantees through the L2 settlement model make institutional and exchange listings easier to justify. The fixed-supply token model takes RON out of the "high inflation gaming token" bucket and into something closer to ETH or major L2 native tokens on a supply curve basis. Both of those should help liquidity and listings over the next 6 to 12 months.

The marketplace fee increase is the line item most likely to attract pushback. Power sellers and NFT traders absorb the cost directly, and 2.5x is a sharp jump even if the destination is the treasury. The community response to the fee change will be a signal to watch over the next few weeks as the first full month of post-migration trading completes.

Risk Factor

Risk factor: Major hard forks always carry execution risk in the first weeks. Wallet integrations, exchange deposit and withdrawal pipelines, bridge contracts, and node operators all need to converge on the new chain. Until the entire downstream stack confirms compatibility, treat unusual delays or fee spikes on Ronin as expected friction rather than a sign of a deeper problem.

What Happens Next

The immediate technical priority is confirming that every active game and DEX on Ronin is reading the new chain correctly. Wallets that had not updated to release 1.2.2 before the fork block lost the canonical chain and need to upgrade.

The medium-term watch list:

First-month marketplace volume and how the 2.5x fee impacts sales velocity
The first Proof of Distribution monthly payout, which will set expectations for builders on what kind of yield they can plan around
RON staking participation under the new sub-1% inflation regime, where holders are no longer being paid as much to lock the token
Whether new game launches on Ronin accelerate now that the chain is positioned as a real Ethereum L2 rather than a gaming-specific sidechain

The migration is the single biggest infrastructure change Ronin has shipped since launch. By the early morning of May 13 the team had signaled that the technical part was almost complete. The economic and ecosystem implications will play out over the next several months.

Frequently Asked Questions

Do I need to do anything as a player?

No. The Ronin team confirmed during the migration window that no action is required from users or players. Your NFTs, your RON balance, and your in-game assets remain where they were. Wallet software that supports Ronin should update automatically to the new chain.

Will gas fees change after the migration?

Ronin gas fees on the L2 are paid in RON and remain low by Ethereum L1 standards. The exact post-migration fee curve depends on how much L1 blob space Ronin consumes during peak usage, but day-to-day swaps and NFT transfers should remain in the cents-per-transaction range.

What happens to RON staking?

Annual inflation drops from over 20% to under 1%, which directly reduces staking yields paid to validators and stakers. The 90 million RON formerly reserved for staking moves into the treasury. Stakers still earn from a portion of sequencer revenue and marketplace fees rather than from inflation, but expected nominal yields will be lower under the new model.

Why did Ronin migrate now?

Sky Mavis and the Ronin team have been signaling this transition for over a year. The core arguments are Ethereum-grade security through the L2 model, removal of the sidechain bridge as an attack surface, and access to Ethereum's institutional and exchange infrastructure without giving up the low fees that made Ronin viable for gaming in the first place.

What is Proof of Distribution and who qualifies?

Proof of Distribution is a new monthly payout program that rewards builders with RON based on a merit score calculated from on-chain activity. Gas spend, user acquisition, NFT and DEX volume, and smart contract activity all feed the score. Any developer running a contract on Ronin can qualify by registering at the Proof of Distribution portal.
