Each chain is assigned a subdomain, such as base.on.eth, that resolves verifiable metadata including chain IDs, interoperable addresses, and CAIP-2 identifiers. The solution replaces the current offchain mappings maintained by wallets and apps. The implementation leverages ERC-7828, Wonderland's Interop SDK, and ERC-7930 addresses to bring human-readable cross-chain names in the format domain.eth@chain. The ENS DAO retains ownership of the namespace, with chain operators managing their own records. Ethereum apps and wallets can visit interopaddress.com to support chain-aware addressing.Across Token Buyout ProposalAcross Protocol, a cross-chain bridge built on an intent-based architecture, published a temperature check proposal seeking to dissolve its DAO and transition to a newly formed U.S. C-corporation, AcrossCo. The proposal would allow ACX token holders to either exchange their tokens for equity in AcrossCo at a 1:1 ratio or sell them for USDC at $0.04375 per token. Risk Labs, the team behind the protocol, said the change aims to address institutional friction, arguing that the DAO and token structure have limited its ability to secure enterprise partnerships and enter enforceable contracts. The ACX token surged roughly 81% following the announcement.Mastercard Crypto Partner ProgramMastercard launched a Crypto Partner Program consisting of more than 85 firms, including Binance, Circle, Optimism, PayPal, and Paxos, to connect stablecoin payments with its global commerce network. The program focuses on cross-border transfers, B2B payments, and stablecoin settlement using centralized stablecoins USDC, PYUSD, and USDG. The program gives crypto-native companies access to Mastercard's fiat distribution infrastructure. MetaMask Integrates Uniswap RouterMetaMask integrated Uniswap as its primary swap provider, routing trades directly through Uniswap v2, v3, v4, and UniswapX across more than 16 chains. The integration gives users access to Uniswap liquidity without having to leave the wallet or rely on other aggregators. MetaMask joins OKX, Fireblocks, and Ledger as partners building on the Uniswap routing layer.Other NewsZyfai agents yield stackVitalik on deep fundingx402 Facilitator on PolygonLido Q4 2025 metricsIncreasing max contract sizeHow Worldcoin scaledDisclaimer: Content is for informational purposes only, not endorsement or investment advice.
