River, a chain-abstract stablecoin system, has announced a deadline for users to send their River Pts to the official buyback address by 21:00 on November 20 (UTC+8). The team will verify transactions from November 20 to 23, with BNB buyback distributions set for November 23. This move follows a temporary halt in Pts conversions due to price volatility attributed to a coordinated attack, as previously reported by Foresight News.
