Optimism highlighted that Ink, Kraken's Layer 2, is driving significant volume on the OP Stack, sharing metrics from its network since January 2026 in a weekly ecosystem recap (source). No specific figures were provided in the announcement beyond noting growth since the start of the year.
Whitechain is migrating from a standalone L1 to an Ethereum L2 on the OP Stack, targeting institutional and B2B finance use cases, per Optimism's announcement.
L2BEAT rebranded as ETHBEAT, announced alongside Devcon 8 in Mumbai. The Ethereum analytics platform is widening its coverage beyond Layer 2 rollups to include privacy, interoperability, and staking, including a new CROPS guide, while keeping L2 monitoring as a core function (source).
Immutable announced plans to upgrade Immutable Chain from its custom Geth fork to an OP Stack-based architecture by mid-2027, targeting faster transactions and closer alignment with Ethereum's security, including 1-second block times. Optimism recapped the migration in its weekly ecosystem roundup (source).
Soneium announced its next phase on OP Enterprise: an onchain entertainment economy built around tokenized intellectual property, with Moriusa becoming the first tokenized IP on the network. The Soneium Portal focuses on three asset types — IP Tokens, IP Vaults, and IP Bonds — backed by an ecosystem of more than 250 applications across music, gaming, and other entertainment verticals, per Optimism's announcement and its weekly roundup.
The Startale card is now live, letting users use their Soneium assets for everyday spending. Startale Labs is the developer behind the Soneium chain, and the card extends its ecosystem from onchain entertainment into real-world payments (source).
ZisK, an open-source ZK proving toolstack built around a zkVM, is proving OP Mainnet live with an average proving time of 11 seconds on four consumer GPUs. ZisK lets developers build circuits in high-level languages such as Rust, and the milestone points to low-cost, consumer-hardware ZK verification for OP Stack chains (source).
Aero, the merged Aerodrome-Velodrome liquidity layer, is piloting an MEV tax on its Slipstream V3 pools on OP Mainnet. The tax scales with the priority fee a trader pays to jump the queue, redirecting value that would otherwise go to block builders to liquidity providers and sAERO holders instead, per Optimism's announcement.
Orderly Network is now live on X Layer, OKX's Ethereum Layer 2, per X Layer and Optimism's weekly ecosystem recap. The deployment lets builders on X Layer plug into Orderly's shared liquidity and perpetual trading infrastructure to create new onchain markets.
Aave has enabled stablecoin deposits on its mobile app for OP Mainnet, letting users deposit stablecoins directly from the app. The launch was highlighted in Optimism's weekly ecosystem recap as one of the week's OP ecosystem milestones.
Aerodrome and Velodrome merged into Aero, a single cross-chain exchange live on seven networks including OP Mainnet, with all AERO supply going to existing AERO and VELO holders.
World Chain becomes the first production L2 to stream EIP-7928 block access lists, live on mainnet August 17.
Optimism token holders approved a program to periodically buy back OP tokens funded by Superchain network revenue, linking OP's value to ecosystem activity.
Governance-approved fault proofs activated on OP Mainnet, enabling trustless withdrawal validation and advancing the OP Stack to 'Stage 1' decentralization per L2Beat's framework.
The network migrated to the Bedrock architecture, lowering fees, cutting node requirements, and reducing the codebase diff from upstream geth to roughly 300 lines.
An attacker withdrew 20 million OP tokens (~$17.5M) that market maker Wintermute had mistakenly transferred to a non-functional Ethereum multisig address; most funds were later returned by a self-described 'whitehat' hacker.
The native OP token went live, with Airdrop 1 distributing over 200 million OP tokens (roughly 19% of supply) to about 250,000 eligible addresses.
Optimism introduced a two-house governance structure (Token House and Citizens' House), established the non-profit Optimism Foundation, and outlined plans for the OP token and a public goods funding program.
The round was co-led by Paradigm and Andreessen Horowitz, with participation from Sequoia and other investors, bringing total funding to over $175M.
Optimism removed its deployment whitelist and opened its optimistic rollup mainnet (OP Mainnet) to all users.
