Ronin has announced a migration to Ethereum scheduled for May 12, bringing a significant reduction in RON inflation and the introduction of a new merit-based builder reward system called Proof of Distribution. The network will undergo approximately 10 hours of planned downtime between 8am and 6pm PT on that date, during which onchain actions including token swaps, NFT trades, and unstaking will be unavailable.
Four years ago, Ronin was launched because Axie Infinity needed a faster and more efficient network. It worked — onboarding millions of gamers to crypto, with Pixels proving the model could scale again. Now Ronin is returning to Ethereum, its original “mothership,” as the Layer 2 landscape has matured with battle-tested infrastructure like the OP Stack.
What’s Changing
- Ronin will migrate to Ethereum as a Layer 2 network, with the hardfork scheduled for block #55577490.
- RON inflation will drop from over 20% to less than 1% following the migration.
- A new automated reward system called Proof of Distribution will distribute RON to builders monthly based on Builder Scores calculated from on-chain activity metrics.
- The Ronin Treasury will receive new inflows including net sequencer profits and an increased Ronin Marketplace fee share, raised from 0.5% to 1.25%.
- Staked RON that remains staked on May 12 will be automatically unstaked after the migration completes.
- RPC node operators on Ronin Mainnet are required to upgrade to release 1.2.2 before the hardfork.
Dates and Rollout
- The Ethereum migration is scheduled for May 12, with the hardfork triggering at block #55577490.
- Approximately 10 hours of mainnet downtime is expected on May 12 between 8am and 6pm PT.
- Proof of Distribution rewards will be distributed monthly using data from the previous four weeks.
- Builder Score weightings will be reviewed by Sky Mavis on a monthly basis and may change over time.
- Registration for Proof of Distribution is currently open ahead of the May 12 migration.
Numbers and Rules
- RON inflation will fall from over 20% to less than 1% after the migration, representing more than 20 times fewer tokens entering circulation via reward emissions.
- The remaining 90 million RON set aside for staking will flow into the Ronin Treasury after the migration.
- Ronin Marketplace fee allocation to the Treasury increases from 0.5% to 1.25%.
- Proof of Distribution Builder Score weightings are: NFT volume 20.95%, DEX volume 20.54%, gas spend 18.13%, contract volume 16.37%, active users 12.89%, and new users 11.12%.
- New and active users must hold more than 10 RON to count toward a builder’s score.
- Treasury inflows after the migration will also include net sequencer profits, defined as total gas revenue minus blob fees and expenses.
Important Note on Builder Rewards
Sky Mavis will review Builder Score weightings monthly. Certain high-volume contracts (such as Ronin Market itself) will not receive Proof of Distribution rewards, as the system is designed to reward builders rather than the marketplace.
What This Means for Players
- On May 12th there will be approximately 10 hours of downtime (8am–6pm PT). During this time you won’t be able to perform on-chain actions such as token swaps, NFT trades, or unstaking. Games may be paused during the migration window.
- If you have staked RON, it is recommended to unstake before May 12. Any RON still staked on that date will be automatically unstaked after the migration completes.
