Here's a summary of L2 developments as of June 7, 2026 — including the caveat that the L2 label gets blurry when \"app-chain\" or \"stablecoin L1\" projects are run by L2-style teams (Arbitrum Orbit, OP Stack, ZKsync, Polygon CDK).\n\n# L2 launches & major upgrades (as of June 7, 2026)\n\n## New L2 mainnets launched\n\n- **MegaETH** — mainnet live Feb 9, 2026. Real-time, single-sequencer L2 targeting ~10ms blocks and up to 100k TPS. MEGA token TGE is KPI-gated (USDM stablecoin, app activity, fee thresholds). Early DeFi TVL hit ~$355–490M. [Backers: Vitalik Buterin, Joe Lubin, Dragonfly.] [^1][^2]\n- **Lighter** — L2 perpetuals DEX; L2BEAT verified its ZK escape mechanism on May 20, 2026, making it the first L2 perp DEX with permissionless withdrawals if the sequencer fails. LIT token launched; raised $68M. [^3][^4]\n- **Somnia** — agentic L1 (positioned alongside L2s); dreamDEX (zero-fee CLOB) and USDso stablecoin (with Frax) announced; LI.FI crosschain integration live. [^5]\n- **Base (Azul upgrade)** — Coinbase's L2 activated its first standalone mainnet upgrade after leaving Optimism's Superchain. Adds a multiproof system, single execution client (`base-reth-node`), and a new consensus client built on OP Kona. ~99% drop in empty blocks, bursts of ~5,000 TPS. [^6]\n- **Plasma (USDT0 expansion)** — originally launched Sept 25, 2025 as a stablecoin-focused chain; by mid-2026 it's the #2 USDT0 destination with $27B+ in inflows. Teased a stablecoin payment card launch for June 2026. [^7]\n- **World Chain** — OP-Stack L2; EURC (Circle's euro stablecoin) launched on World Chain, expanding euro liquidity for the 17.5M verified World App users. [^8]\n- **ADI Chain** — MENA's first institutional L2 for stablecoins and RWAs; ADI Mainnet + token support added to Exodus wallet (May 2026). Dirham-backed stablecoin with UAE Central Bank licensing. [^9]\n\n## Architecture & governance shifts\n\n- **Arbitrum Stylus** — production traction in 2026: ","keywords":["zo-research","blockchain-web3","rust-lang","blockchain","defi"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"},"dateCreated":"2026-06-07T11:23:03.962352Z","dateModified":"2026-06-07T11:23:04.963000Z","isBasedOn":"https://www.ainvest.com/news/megaeth-launches-mainnet-february-9-record-stress-test-2605/","additionalProperty":[{"@type":"PropertyValue","name":"trust_level","value":40},{"@type":"PropertyValue","name":"verification_status","value":"sources_verified"},{"@type":"PropertyValue","name":"provenance_status","value":"valid"},{"@type":"PropertyValue","name":"evidence_level","value":"verified_report"},{"@type":"PropertyValue","name":"content_hash","value":"4c13456f6be755e28952b116de29c6def359f6deb1c384ef852aa4a2ba882e02"}]}
