Ronin Completes Migration To Ethereum L2
Ronin migrates from a sidechain to an OP Stack L2 led by Conduit, with EigenDA for data availability and a new Proof of Distribution rewards model.
Ronin, a gaming-focused blockchain home to Axie Infinity, completed its migration from an independent sidechain to an Ethereum Layer 2 built on the OP Stack. The transition was led by rollup infrastructure provider Conduit. Ronin uses EigenDA for data availability and will use Boundless Kailua for ZK fraud-proof generation in a future upgrade.
Ronin also dropped annual RON token emissions from 45 million to 5 million tokens per year. Rewards previously directed toward validator incentives will now flow through a new Proof of Distribution system that allocates RON to builders based on metrics correlated with network activity. The Ronin Treasury will now earn sequencer fees, 1.25% of Ronin Marketplace fees, as well as a 90 million RON allocation previously reserved for staking rewards.

Optimism Expands Actions SDK
The updated framework adds embedded wallets, lending via Aave and Morpho, swaps via Uniswap and Velodrome, and multi-chain DeFi across the OP Stack.
Optimism expanded its Actions SDK, evolving it from an early developer preview into a more complete framework for embedding DeFi directly into applications. The updated SDK introduces fully integrated onchain financial actions, allowing users to lend, earn yield, swap tokens, and make payments without needing external wallets.
The Actions SDK supports lending through Aave and Morpho, and token swaps via Uniswap and Velodrome, with built-in routing and liquidity handling. A standardized action interface unifies all operations under a consistent structure, reducing integration complexity. The expansion deepens wallet infrastructure, adding embedded wallet integrations via Privy, Turnkey, and Dynamic, with support for EOAs, smart wallets, bundlers, and paymasters. The SDK enables multi-chain DeFi experiences across OP Stack chains.
