JuCoin, a cryptocurrency exchange, is facing allegations of fraudulent proof of reserves (PoR) practices. According to an analysis by @DarcyAri, co-founder of FlashRescue, JuCoin's PoR claims a total reserve of $511 million with a reserve ratio of 123.81%, covering assets like USDT, BTC, ETH, USDC, BNB, and SOL. However, these assets are reportedly linked to a single JuChain address on CoinMarketCap, raising concerns about their authenticity. The analysis highlights that the USDT and USDC tokens on JuChain are ERC20 tokens issued by JuCoin's project team, lacking any cross-chain bridging with official stablecoins from Tether or Circle. This setup allows for arbitrary token issuance, undermining the credibility of JuCoin's reserves. Notably, the PoR address holds 99.99% of these tokens, with only 14 holders across the entire chain, further questioning the legitimacy of JuCoin's solvency claims.
