Gm frENS. Happy Friday, can you believe this week is over?

• SWIFT tests a stablecoin on Linea.

• Eco introduces Permit3 approval contract.

• Fusaka client releases are out for testnets.

• ChinaAMC launches a tokenized fund on Ethereum.

SWIFT, the global cross-border payments network, is testing a stablecoin and onchain payment messaging system on Linea. According to The Big Whale, SWIFT, along with BNP Paribas and BNY Mellon, has begun experimenting with payment infrastructure on Linea, chosen for its cryptographic ZK proof capabilities. Linea is a ZK-EVM rollup developed by Consensys. The initiative centers on a stablecoin-like settlement token designed to reduce intermediaries and cut cross-border transaction times. The SWIFT network connects over 11,500 financial institutions across more than 200 countries and territories. Linea is currently the largest ZK rollup by total value secured.

Eco released Permit3, a new approval contract that extends Uniswap’s Permit2 standard. Permit2 standardized ERC-20 token approvals with signature-based and time-bound permissions. Permit3 expands the contract to support multiple chains and multiple tokens, including ERC-721 and ERC-1155. With Permit3, a single signature can authorize token operations across multiple chains. Permit3 is fully backward-compatible with Permit2 and integrates ERC-7702 for account abstraction. Permit3 is deployed at a universal address across all major EVM chains. Users must first approve Permit3 to use the new standard.

Fusaka, Ethereum’s next upgrade, is scheduled to go live starting with the Holešky testnet on October 1st at 08:48 UTC, on Sepolia on October 14th, and on Hoodi on October 28th. Fusaka-compatible client releases are now available for both consensus and execution layer clients on testnet. Testnet node operators must update their client software ahead of the activations. Fusaka introduces 13 EIPs, delivering improvements in scaling, performance, and user experience. The headline feature, PeerDAS (EIP-7594), enables higher blob throughput, reducing L2 transaction costs. To further expand blob capacity, Blob Parameter Only forks will gradually increase per-block blob limits, first to 10/15 and then to 14/21. A mainnet activation is set for December 3rd, assuming testnet deployments are successful.

ChinaAMC, one of China’s largest asset managers, has launched the ChinaAMC USD Digital Money Market Fund Class I USD on Ethereum. The fund is tokenized under the ticker CUMIU, represented as an ERC-20 token, and already has approximately $502 million USD in assets under management (AUM).

• Fusaka 60m default gas limit.

• SharpLink plans to tokenize SBET.

• Cloudflare unveils NET Dollar.

• CCTP V2 goes live on Ink.

At this week’s ACDE #221, Ethereum core developers agreed to set the default mainnet gas limit in Fusaka client releases to 60 million gas per block, raising it from the current 45 million. Increasing the gas limit allows each block to carry more data, thereby improving transaction throughput. Gas limit increases occur automatically once more than 50% of validators signal for an increase. Developers are also preparing for the Fusaka upgrade to activate on testnets throughout October. Teku, Lodestar, and Besu have already shipped testnet-compatible releases, with the remaining clients expected to follow in the coming days. After that, the Ethereum Foundation will issue an official announcement. If testnet forks proceed smoothly, Fusaka is scheduled for mainnet activation on December 3rd.

SharpLink Gaming, the world’s second-largest corporate holders of ETH with 838k ETH and 3,815 ETH in staking rewards earned, announced plans to natively tokenize its SEC-registered $SBET shares on Ethereum. The tokenization will use Superstate’s platform, with Superstate serving as Digital Transfer Agent. Tokenized SBET shares will be legally equivalent to traditional equity but can be held in self-custodied wallets and integrated into onchain products. SharpLink and Superstate will explore compliant secondary market trading of tokenized SBET shares on AMMs and other uses across DeFi protocols.

Cloudflare, the largest Content Delivery Network (CDN) provider, introduced NET Dollar, a USD-backed stablecoin designed for the agentic web. Designed to support microtransactions, pay-per-use models, and automated agent-to-agent payments, NET Dollar aims to modernize the Internet’s financial rails and incentives. The announcement follows Cloudflare’s and Coinbase’s launch of the x402 Foundation earlier this week, which aims to establish the x402 payments protocol as a universal standard for AI-driven payments across industries and platforms. Cloudflare did not specify which blockchain the stablecoin will launch on.

CCTP V2, the latest version of Circle’s Cross-Chain Transfer Protocol, is now live on Ink, enabling fast, secure, and capital-efficient USDC transfers using a burn-and-mint model, without relying on liquidity pools. The CCTP V2 protocol features smart contract hooks for post-transfer actions. Ink now joins Ethereum, Base, Avalanche, Arbitrum, and Linea as supported CCTP V2 chains. Circle also deployed support for native USDC on Ink, Kraken’s Ethereum Layer-2 chain built on the OP Stack.

Gm frENS. Happy WENsday, you're halfway through the week!

• TOOL goes live on Hoodi testnet.

• Reserve launches LCAP Index DTF.

• Ethereum hits 6 blobs per block.

• EF launches the Ethereum Everywhere team.

NuConstruct launched Trustless Orderflow Operations Layer (TOOL), now live on the Hoodi testnet. Coined as Ethereum’s Hyperscale Co-processor, TOOL is a permissionless scaling layer that delivers 1-second finality without protocol or validator changes. It uses sealed-bid auctions to process private orderflow offchain. TOOL connects wallets, traders, RPCs, solvers, and searchers into one permissionless network on Ethereum L1. TOOL is supported by Ethereum’s leading staking providers, including Lido, Rocket Pool, SSV, Obol, and is undergoing a full audit by security firm Sigma Prime.

Reserve Protocol launched the Large Cap Index Decentralized Token Folio (LCAP DTF), a single index token representing a basket of the 10 largest crypto assets. The token tracks CF Benchmarks’ Large Cap Index, covering about 95% of the crypto market, and is designed as an institutional-grade, fully collateralized, on-chain portfolio. LCAP is powered by Reserve Protocol’s onchain infrastructure mint/redeem, governance, composability) and built on Base. It will be tradable across both centralized and decentralized exchange venues, offering permissionless access to diversified crypto exposure.

Ethereum’s blob capacity has reached a new high of six blobs per block. The network currently has a target of 6 blobs per block and a maximum of 9 blobs per block. According to data analyst hildobby, Base and Worldcoin dominate actual blobspace usage, accounting for about two-thirds of it. Vitalik Buterin noted that the Fusaka upgrade, targeted for December 3, 2025, will address the current blob demand surge. Fusaka introduces Peer Data Availability Sampling (PeerDAS), allowing nodes to verify data availability by sampling small subsets rather than downloading entire blobs. It enables safer scaling, with throughput eventually increasing by up to 8x, from 6 to 48 blobs per block. After Fusaka, Blob Parameter Only (BPO) forks will gradually and automatically raise blob limits further.

The Ethereum Foundation launched the Ethereum Everywhere team to amplify and connect communities and events worldwide. The initiative focuses on strengthening Ethereum’s social layer, including the people, gatherings, and collaborations that sustain the ecosystem. The team will support grassroots groups, innovation hubs, meetups, and developer workshops.
