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.
