Solidity maintainer Artem Chystiakov released a paper introducing a privacy-preserving, zero-knowledge (ZK) multisignature wallet for Ethereum. The system preserves anonymity and confidentiality in multisig approvals and voting while eliminating centralized trust. The architecture includes two smart contracts, ZK circuits, and relayers to support private and verifiable onchain operations. The design replaces interactive key-sharing with deterministic derivation and ensures all cryptographic actions are ZK-verifiable and auditable onchain without leaking private data.

• EigenLayer launches EigenAI.

• Coinbase achieves $1b in loans.

• SWIFT leverages Chainlink CRE.

• Report on Fusaka Devnet-5.

EigenLayer introduced EigenAI, a verifiable LLM inference service, and EigenCompute, a verifiable offchain execution system, now live on mainnet alpha. The services allow developers to build autonomous, transparent, and trustworthy AI agents with cryptoeconomic guarantees. EigenLayer says traditional AI models are opaque black boxes, leaving users vulnerable to tampered inputs, altered outputs, and inconsistent model quality. EigenAI provides an OpenAI-compatible API that ensures untampered prompts, responses, and models. EigenCompute complements it by enabling verifiable offchain computation, starting with Trusted Execution Environments and expanding to cryptoeconomic guarantees and zero-knowledge proofs.

Coinbase has surpassed $1 billion in Bitcoin-backed loans through its integration with the Morpho lending protocol on Base. The setup, dubbed the “DeFi mullet”, allows users to borrow USDC against their Bitcoin holdings via Coinbase. Behind the scenes, Bitcoin is converted into Coinbase Wrapped Bitcoin (cbBTC) on Base and then supplied to the Morpho lending protocol. Users can manage their loans directly in the Coinbase app. To qualify, a minimum of $20,000 in Bitcoin is required, with a maximum loan-to-value (LTV) ratio of 86%. If the LTV threshold is exceeded, loans are automatically liquidated. The service is currently available to U.S. users, excluding residents of New York.

Chainlink, in collaboration with Swift and UBS, introduced a solution enabling financial institutions to manage digital asset workflows directly from their existing systems. By combining Swift’s ISO 20022 messaging with the Chainlink Runtime Environment (CRE), institutions can trigger onchain events without overhauling their infrastructure. UBS’s tokenization unit piloted the solution on a tokenized fund smart contract, with workflows executed under Chainlink’s new Digital Transfer Agent (DTA) standard.

Sunnyside Labs, a core contributor to the Optimism Collective, released a report on Fusaka Devnet-5, stress-testing blob throughput on PeerDAS. The ~1,700-node devnet (representing ~1/8 of Ethereum Mainnet) sustained 22 (max 33) blobs and reached 48 (max 72) blobs per block. The main limiter was bandwidth, with full nodes frequently maxing out their 50 Mbps uplink. Current blob parameter only (BPOs) forks are scheduled to scale up to 14 blobs per block (max 21).

Gm frENS. Happy Monday, here's to a new week!

• Morpho V2 goes live on Ethereum.

• SWIFT announces its shared ledger.

• OP Mainnet activates Flashblocks.

• BitMine buys 234,850 ETH.

Morpho Labs launched Morpho V2 on Ethereum, the latest iteration of its lending platform, introducing advanced risk management controls. Morpho Vaults V2 offers yield-generating vaults with instant liquidity and the ability to allocate across any current or future Morpho protocol. Morpho V2 addresses key DeFi limitations such as the lack of custom loan terms, predictable rates, and unified liquidity. It complements Morpho V1, which currently secures over $7 billion in TVL, and is designed to attract institutional capital to onchain lending. The next milestone will be Markets V2, a peer-to-peer system enabling customizable fixed-rate, fixed-term loans.

SWIFT, the global cross-border payments network, announced that it is integrating a blockchain-based shared ledger into its financial infrastructure. The initiative aims to enable instant, always-on, real-time cross-border payments across more than 200 countries. Developed with Consensys as a prototype partner, the shared ledger will provide a record of interbank transactions, enforce compliance through smart contracts, and interoperate with both existing and emerging payment rails. Swift says this integration will bring improved liquidity management, predictable payments, and a foundation for tokenized asset transfers and multi-currency transactions. Consensys is supporting the proof-of-concept with its infrastructure expertise, which includes access to MetaMask, Infura, Besu, and Linea.

Optimism activated Flashblocks on OP Mainnet, enabling 250 millisecond transaction confirmations. Built by Uniswap Labs and Flashbots, Flashblocks run inside Trusted Execution Environments (TEEs), combining sub-second speed with provable, fee-based transaction ordering for fairness and transparency. Instead of waiting for full blocks, OP Mainnet now streams and confirms 250ms sub-blocks, reducing slippage, keeping prices fresh, and improving execution accuracy for swappers. Flashblocks are now live across OP Mainnet, Unichain, Base, and Worldchain.

BitMine Immersion Technologies Inc. acquired an additional 234,850 ETH over the past week, increasing its Ethereum treasury to 2.65 million ETH valued at more than $10.6 billion. The company remains focused on its long-term objective of securing 5% of the total ETH supply. Meanwhile, Bit Digital, a top-10 DAT, is conducting a $100 million convertible notes offering, with proceeds allocated for ETH purchases.
