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 Introduces Permit3 Approval ContractEco 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 Client Releases For TestnetFusaka, 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 Tokenized Fund On EthereumChinaAMC, 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).Other NewsRead: Race To Rewire Wall St.EIP-7732 breakout call #24Ethproofs call #5 wrappedNethermind RISC-V 32-bit supportSequence on Fusaka-readinessUniswap smart wallet supportLido proposes NEST buyback systemLayerOnEth open-sourced WAVSSAFU partners with EigenLayerThat's it for this week!
