Gm frENS. Happy Uptober, cheers to a new month!

• Fusaka activates on Holešky testnet.

• Open-source EVM relayer released.

• WalletConnect expands into POS systems.

• ADI Chain joins the Elastic Network.

The Fusaka upgrade has successfully activated on the Holešky testnet, introducing ~12 Ethereum Improvement Proposals (EIPs) that improve scalability, performance, and user experience. The next testnet activations are scheduled for Sepolia on October 14th, followed by Hoodi on October 28th. Testnet node operators must update their client software ahead of the activations. The Holešky testnet will be deprecated about two weeks after Fusaka activates on Ethereum mainnet. Assuming testnet rollouts proceed smoothly, Fusaka is set to go live on Ethereum mainnet on December 3, 2025. Fusaka’s headline feature, PeerDAS (EIP-7594), brings higher blob throughput, significantly reducing L2 transaction costs and enhancing Ethereum scalability.

Aave engineer Josh Stevens introduced rrelayer, an open-source EVM relayer built in Rust for seamless transaction relaying. Supported by the Ethereum Foundation and released under the MIT license, rrelayer works across any EVM-compatible network and provides easy integration through REST APIs, SDKs, and a CLI. It features config-driven setup, multi-chain support, secure signing via providers like AWS KMS and Privy, and out-of-the-box capabilities such as automatic top-ups, allowlists, API key permissions, and webhooks. Rrelayer will support no-code YAML automation for transaction scheduling and event-driven execution.

WalletConnect, the infrastructure provider connecting wallets to dapps, introduced WalletConnect Pay, a new solution enabling stablecoin payments at point-of-sale (POS) systems across Asia in partnership with DTCPay. The solution delivers seamless checkout akin to scanning an Alipay QR code and supports over 500 wallets. Stablecoins already account for 72% of payments on WalletConnect. With DTCPay, merchants can now accept stablecoin payments without new hardware or complex integrations. The launch marks WalletConnect’s evolution from a wallet-app connectivity layer to core infrastructure for onchain payments and POS.

ADI Chain, an EVM L2 network powered by GPU computing, is joining ZKsync’s Elastic Network as the first chain built with Airbender, ZKsync’s RISC-V–based zkVM. Airbender is designed to support future cross-chain and modular interoperability. Backed by leading UAE institutions and regulated by the UAE Central Bank, ADI Chain is introducing the first Dirham-backed stablecoin.

• 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.
