This will facilitate the phased on-chain commercialization of local physical assets, with the entire cooperation framework tailored to align with Korea's financial regulatory framework.
Binance-labeled wallets saw over $5.6 billion in outflows amid suspected attack
Odaily reports: On-chain monitoring shows that the total assets flowing out of Binance-labeled wallets amounted to approximately $5.643 billion.

The tally excludes change outputs and avoids double-counting subsequent transfers and swaps. Tether and USDC issuer Circle have frozen at least $2.316 billion in stablecoins, including approximately $1.493 billion in USDT and $823 million in USDC.
Over the past two weeks, a whale has accumulated 3 million OP tokens worth nearly $4 million.
According to Arkham's monitoring data, a whale has accumulated 3 million OP tokens over the past two weeks, with a position valued at approximately $3.855 million at an average purchase price of $1.285, seemingly betting on an imminent resurgence in the Layer 2 sector. As 2026 draws to a close, Optimism’s revenue has only slightly surpassed $3 million, representing a year-over-year decline of approximately 83.3%. Analysts suggest that the sharp revenue drop may have constrained Optimism’s available capital, leaving it unable to execute its previously approved OP buyback plan.

Protocol-Level MEV Auction Goes Live, Aerodrome Slipstream V3 Expected to Generate Tens of Millions in Related Revenue
Odaily News: Aerodrome's Slipstream V3 has gone live, introducing protocol-level internal MEV auctions to its concentrated liquidity AMM.

This version also introduces dynamic fees that automatically increase when market volatility intensifies, and retains Uniswap V3's concentrated liquidity design, achieving capital efficiency up to 4,000 times that of traditional AMMs. Aero plans to merge Aerodrome on Base and Velodrome on Optimism into a single AERO token, and to launch on Ethereum mainnet in Q2 2026. Aero Lite has already launched Slipstream pools on Circle's Arc, and Dromos Labs is developing pool-level fee rebates and KYC options for institutional clients.
