Anchorage Digital Bank will serve as the issuer, with Cantor as reserve custodian. Bo Hines, former Executive Director of the White House Crypto Council, has been appointed CEO of Tether USA₮. USA₮ aims to provide businesses and institutions with a regulated digital alternative to cash and traditional payment systems. The launch builds on Tether’s scale, with its flagship stablecoin USD₮ reaching a market cap of $169 billion as well as Tether’s position as the 18th-largest holder of U.S. Treasuries. Polymarket Integrates Chainlink Data Streams -------------------------------------------- Polymarket, the world’s largest prediction market, [partnered](https://www.prnewswire.com/news-releases/polymarket-partners-with-chainlink-to-enhance-accuracy-of-prediction-market-resolutions-302555123.html) with Chainlink to enhance market resolution accuracy and speed, starting with asset pricing markets. Polymarket integrated Chainlink’s Data Streams and Automation on Polygon PoS mainnet, enabling decentralized, timestamped, and verifiable data inputs, along with automated onchain settlement. Beyond deterministic pricing markets, the two companies are exploring ways to resolve more subjective markets, reducing reliance on social voting and minimizing resolution risks. By eliminating single points of failure, Chainlink ensures outcomes are based on cryptographic truth. Since 2020, Polymarket has settled billions of dollars in prediction market volume. Polygon Activates Rio Upgrade On Testnet ---------------------------------------- Polygon [activated](https://polygon.technology/blog/rio-upgrade-live-on-testnet-polygon-continues-to-go-gigagas) the Rio upgrade on its Amoy testnet, introducing Validator-Elected Block Producers (VEBloP), a new fee redistribution model between block producers and validators, and Witness-Based Stateless Verification. The updates boost throughput, shorten confirmation times, prevent reorgs, and lower node hardware requirements. Rio sets the path to ~5,000 TPS through incremental block gas limit increases and halving block time, marking a key step in Polygon’s GigaGas roadmap. The upgrade is scheduled to go live on Polygon mainnet in October 2025 ETH Strategy Announces ESPN Staking ----------------------------------- ETH Strategy, a crypto-native ETH treasury protocol, [introduced](https://blog.ethstrat.xyz/espn-staking) staking for its Perpetual Note product, ESPN. Designed to monetize ETH volatility, ESPN delivers USD-denominated yield in USDS by underwriting long-dated ETH calls while selling shorter-dated ones. Rewards for liquidity providers are distributed weekly: part of the premiums are reinvested into ETH to expand the asset base, while the rest funds staking incentives. Fileverse dDocs Secure Sharing ------------------------------ Fileverse [updated](https://x.com/fileverse/status/1966516319815106674) its dDocs word processing tool to support real-time collaboration with end-to-end encryption, powered by stateless WebSocket servers (WSS) for messaging.
