Cryptocurrency exchange CoinEx has sparked fears of a hack following massive outflows from their hot wallets on Tuesday. 

Per Etherscan data, at a cryptocurrency address received nearly 5,000 ether from a known CoinEx hot wallet at 9:20 am ET. Since then, the address has been systematically withdrawing sums of other cryptocurrencies from the exchange and swapping them for ether (ETH) using decentralized exchange Uniswap in what appears to be an ongoing attack. 

Two other addresses are exhibiting similar activity, with the total sum withdrawn and swapped on Ethereum totaling $18.6 million at press time. 

Per security firm Cyvers Alerts, an additional $8.5 million in crypto assets were withdrawn to an address on the Tron blockchain, and a $290,000 in assets was withdrawn to a Polygon address, totalling $27.4 million between the three chains.

Trading of the President's TRUMP memecoin sent the market capitalization to over $15B, resulting in all-time highs for Solana’s Real Economic Value, DEX volumes, and stablecoin supply. This event further validates Solana as the venue for high-throughput onchain activity, with Solana DEXs and DeFi applications as primary beneficiaries, while also signaling to further experimentation, utilization, and adoption of memecoins as legitimate financial instruments for speculation, crowdfunding, or capital formation. President Trump’s continued willingness to experiment in crypto reaffirms a highly-favorable political and regulatory climate for the industry.
