Mastercard announced plans to support stablecoin settlement on its global payments network, with supported stablecoins including USDC, PYUSD, USDG, USDP, RLUSD, and SoFiUSD across networks like Arbitrum, Base, Ethereum, and Polygon. Stablecoin settlement is provided as an additive option to Mastercard's existing payments infrastructure, aimed at cross-border payments, and treasury operations. USDC is already supporting early onchain settlement flows, with further expansion across regions and stablecoins planned for merchants and acquirers.
KPK launched ETH Yield Term on Euler, a fixed-rate WETH lending vault that sets its borrow rate once per calendar month rather than continuously based on utilization. The borrow rate is anchored to Treehouse's Ethereum Staking Rate (TESR) and stays within a 2.05–2.50% APY band, addressing the volatile variable-rate ETH borrow costs that hit borrowers across DeFi during May's ETH rate squeeze. The vault is live with two cyclical markets, wstETH Term and tETH Term, The vault prices collateral at fundamental redemption value to avoid depeg-triggered liquidations.
BitMine Immersion Technologies (BMNR) filed a preliminary prospectus for 3,000,000 shares of Series A Perpetual Preferred Stock at a 9.50% yield, priced at $100 per share and targeting $300 million in gross proceeds. The dividend is fixed at 9.5% annually, paid in cash and accumulating weekly, with the proceeds set to be staked on Ethereum via BitMine's MAVAN network. BitMine has already amassed over 5.4 million ETH in its digital asset treasury, though the fixed dividend commitment sits ahead of common shareholders and has raised concern about added obligations.
