The past 24 hours have seen a flurry of high-impact developments across the cryptocurrency, blockchain, and macroeconomic landscapes. From major protocol launches and regulatory moves to strategic corporate expansions and government-level crypto adoption, the ecosystem continues to evolve at an accelerated pace. This comprehensive update covers the most critical updates shaping the future of digital finance.
Polyhedra Launches Phoenix Revival Plan with Privacy Stablecoin on Horizon
In a bold move to rebuild trust after the June 15 liquidity attack, Polyhedra has unveiled its Phoenix Revival initiative. The program rewards early supporters who staked ZKJ on Ethereum or BSC before 21:00 UTC on June 15, offering exclusive access to future product incentives and ecosystem airdrop whitelists based on snapshot staking proportion (SP).
Polyhedra’s roadmap now includes several high-potential projects:
- ZKML (Zero-Knowledge Machine Learning): zk-inference demo already supports 8B parameter models; Proof of Humanity launching Q3 2025.
- Privacy Stablecoin: Testnet expected in July 2025, mainnet slated for September.
- Dark Pool DEX: A privacy-focused decentralized exchange launching testnet in Q4 2025, mainnet in Q1 2026.
- EXPchain: ZK-native Layer 1 with testnet live; full ZK verification and zkML integration by Q4 2025.
Katana Mainnet Live with $100M+ Locked and 1B Token Incentive Program
Katana, a DeFi chain incubated by Polygon and GSR, has officially launched its mainnet with over $240 million in pre-deposits. The platform introduces a two-year liquidity mining program distributing 1 billion KAT tokens, rewarding users for depositing core assets like USDC, USDT, AUSD, and ETH.
Key innovations include:
- VaultBridge: Enables seamless cross-chain asset movement.
- Chain-on-Liquidity (CoL): Enhances capital efficiency.
- AUSD: Native stable asset for yield generation.
Early users are already earning yields via Yearn V3 vaults and receiving additional incentives from Morpho and Sushi. KAT token unlocking is scheduled for February 20, 2026, after which stakers can become vKAT holders and participate in governance and revenue sharing.

Circle Files for U.S. National Bank Charter to Secure USDC Reserves
Stablecoin giant Circle has applied for a U.S. national bank charter under the Office of the Comptroller of the Currency (OCC), aiming to establish First National Digital Currency Bank, N.A. While it won’t offer traditional banking services like loans or cash deposits, the move would allow Circle to act as a regulated custodian for USDC reserves and institutional crypto assets.
Analysts suggest this positions USDC as a frontrunner under the upcoming GENIUS Act, potentially making it the largest regulated stablecoin in the U.S. With a current market cap of $61.5 billion, Circle’s regulatory push could set a new standard for transparency and compliance.
FAQ: Understanding Circle’s Bank Charter Move
Q: What does Circle’s bank application mean for USDC users?
A: It enhances trust by placing reserves under federal oversight, potentially increasing institutional adoption.
Q: Can Circle now accept deposits like a regular bank?
A: No—this charter is limited to digital asset custody and does not permit traditional banking activities.
Q: How might this affect competition with other stablecoins?
A: Regulatory clarity could give USDC a significant edge over less-compliant rivals, especially in institutional markets.
Trump-Linked Projects Gain Momentum
Several developments highlight growing crypto involvement by the Trump family:
- American Bitcoin, backed by Eric Trump, raised $220 million via equity sales—partly paid in BTC—for Bitcoin mining infrastructure.
- The official Trump merchandise sites now accept $TRUMP as payment.
- Meanwhile, USD1, another Trump-affiliated stablecoin, hit a record $3.37 billion in 24-hour trading volume—briefly surpassing USDC to become the second-largest traded stablecoin after USDT.
Institutional and Government Moves in Crypto
Robinhood Expands into Blockchain with Stock Tokens
Robinhood launched “stock tokens” in the EU—blockchain-based representations of U.S. equities tradable 24/7 without commission. Initially issued on Arbitrum, they’ll migrate to Robinhood Chain, a proprietary Layer 2. The platform also offers crypto perpetuals and staking (ETH/SOL) for U.S. users.
Kraken Launches 60 Tokenized U.S. Stocks
Kraken introduced xStocks, offering 60 tokenized U.S. equities (e.g., Apple, Tesla) for non-U.S. users. Trading is available five days a week, 24 hours a day—signaling a broader shift toward on-chain asset tokenization.
Kazakhstan Plans National Crypto Reserve
