Odaily Planet Daily News Cryptocurrency exchange CoinFLEX asked Blockchain.com to return its $4.3 million worth of FLEX tokens, otherwise it would initiate legal action. CoinFLEX claimed to have lent Blockchain.com a total of 3 million FLEX last year, but Blockchain.com said the claim was "completely unfounded and purely fictitious, and CoinFLEX did not provide any evidence, documents or on-chain data to support their claims." CoinFlex said Blockchain.com must confirm that it will repay FLEX by March 7, and set the deadline for Blockchain.com to remit the funds as March 21. Otherwise, CoinFLEX said the exchange will face "the initiation of legal proceedings, including but not limited to" formal legal payment requirements. According to the document, from then on, Blockchain.com still has an additional 21 days to repay the funds, including four loans allegedly issued between March and June last year. The request is based on an AMM+ (automatic market maker) participation agreement allegedly signed on April 12, 2022, when the price of Bitcoin was $40,000. But whether the agreement exists remains controversial. (Decrypt)
