Gm frENS. This is the last week in October, make it count!

• JPYC yen-backed stablecoin.

• Abstract enables 200ms block times.

• ETHZilla sells $40m ETH.

• SOON for fast propagation.

JPYC Inc., a Tokyo-based fintech firm, launched JPYC, Japan’s first regulated stablecoin pegged to the yen, now live on Ethereum, Polygon, and Avalanche. The stablecoin is fully backed by Japanese yen bank deposits and Japan Government Bonds (JGBs) in compliance with the country’s Payment Services Act. The stablecoin’s issuance is managed through JPYC EX, a dedicated platform that utilizes Japan’s “My Number” national ID system to ensure compliant transactions. JPYC is designed to support B2B payments, remittances, and DeFi applications, with an ambitious target of reaching ¥10 trillion in issuance within three years.

Abstract Chain, a consumer-focused Ethereum Layer 2, activated 200-millisecond block times, cutting latency by 5x from its previous one-second blocks. The upgrade delivers the speed necessary for real-time applications and seamless UX with one-click transactions. The feature is powered by a custom ZK proving and sequencing system that operates without Flashblocks preconfirmations. Launched in early 2025, Abstract is built on ZKsync’s ZK Stack and utilizes EigenDA for data availability. The network processes around 250,000 transactions daily and secures over $186 million in value.

ETHZilla Corporation, an Ethereum Digital Asset Treasury (DAT) company formerly known as 180 Life Sciences Corp, sold approximately 10,256 ETH from its treasury holdings to initiate a $40 million share buyback program. Since October 24, ETHZilla has repurchased approximately 600,000 shares for about $12 million under its broader $250 million buyback authorization. The company said the buyback aims to support shareholders, reduce shares available for short selling, and increase NAV per share, as its stock trades at a significant discount to NAV. Meanwhile, BitMine Immersion Technologies Inc. added 77,055 ETH to its treasury in the past week, bringing its holdings to 3.3 million ETH.

Gm frENS. We meet again on yet another Friday. Have a great weekend!

• Ledger Multisig charges a fee per tx.

• MegaETH introduces MEGA token.

• L2BEAT verifies Polygon zkProver integrity.

• Nethermind and Besu interop on BALs.

Ledger, a hardware wallet provider, is facing backlash over fees for its new Ledger Multisig product. Built on the open-source Safe protocol, Ledger Multisig enables users to sign transactions for Safe-based multisig wallets using Ledger hardware devices with Clear Signing, which verifies transaction details directly on the device. Initially marketed as a free feature, Ledger later clarified that it charges $10 per standard transfer for ETH sends and non-token actions like governance and 5 basis points on the value for ERC-20 token transfers, on top of network gas fees. Users can avoid the fees by using Safe’s native web app, which features software-based transaction simulations.

MegaETH, an Ethereum Layer-2 network featuring 10 ms block times and a 100,000 TPS architecture, introduced $MEGA, its native token used to power Sequencer Rotation and Proximity Markets. Sequencer Rotation ensures that only one sequencer is active at a time, rotating globally to follow active regions. Operators can stake $MEGA to compete for the active slot, which is selected based on stake size, performance history, and infrastructure quality. Proximity Markets allow apps and market participants to lock $MEGA and bid for sequencer-adjacent colocation space to access minimal latency and faster transaction confirmations. MegaETH is currently in a public testnet phase.

L2BEAT announced that it has successfully reproduced Polygon’s zkProver verifier keys, which are used to validate zero-knowledge proofs. Anyone can independently regenerate and confirm that the onchain verifier matches the published setup. The L2BEAT team verified that the regenerated keys match the deployed verifier contract, including hash and ABI consistency. The process strengthens the cryptographic integrity of Polygon’s ZK system, ensuring that proofs cannot be forged due to incorrect verifier keys.

Quantum Solutions, a Tokyo-based AI and technology company listed on the Tokyo Stock Exchange (ticker: 2338), announced the purchase of 2,365 ETH in the past week, making it the largest Ethereum Digital Asset Treasury (DAT) firm outside the United States. The company now holds a total of 3,866 ETH. The recent purchases were funded through external borrowings and proceeds from recent stock acquisition rights and convertible bonds.

Farcaster announced that Clanker, an AI-driven coin issuance platform, will join its ecosystem and be integrated more deeply into Farcaster’s decentralized social app. Going forward, Clanker protocol fees will be used to buy back and hold CLANKER tokens, and the team has burned all previously accumulated ecosystem tokens held in its treasury. The announcement follows a failed acquisition attempt by Rainbow Wallet in September 2025, which had proposed redistributing Clanker’s treasury assets to token holders.

The Ethereum Foundation is looking to hire a Developer Tooling Coordinator to lead strategy and development efforts that enhance Ethereum’s developer experience. The technical leadership role involves shaping the developer ecosystem, guiding tooling strategy across languages, compilers, libraries, and frameworks, and influencing key architectural decisions. Ideal candidates have a deep passion for the EVM and smart contract development and hands-on experience building developer tools or infrastructure. The position is fully remote, open to candidates worldwide, and anonymous applicants are welcome.

Google Cloud added EigenLayer’s EIGEN token to its Web3 Testnet Faucet, allowing developers to request testnet EIGEN tokens on the Ethereum Hoodi testnet. Hoodi is a long-term Ethereum testnet built to provide developers with a stable environment for staking and validator testing. The Web3 Testnet Faucet also supports the distribution of testnet ETH across all testnets.
