According to @PANewsCN, Yei Finance announced on X that it has temporarily paused its protocol as a precaution due to fastUSD market conditions, is actively investigating, and plans to provide an update within 24 hours; no further progress had been posted at the time reported (source: @PANewsCN). Elixir previously stated that deUSD would serve as the sole backing for the Sei yield stablecoin fastUSD, tying fastUSD to deUSD reserves on Sei (source: @PANewsCN). An analyst estimated Stream Finance's $93 million loss could translate into more than $285 million in risk exposure, with the largest single exposure being Elixir's deUSD, which lent $68 million USDC to Stream—about 65% of deUSD's total reserves (source: @PANewsCN). For trading, the risk linkages identified include fastUSD market conditions, deUSD as sole collateral, and deUSD's $68 million USDC exposure to Stream; monitoring SEI ecosystem liquidity, fastUSD markets, and the 24-hour update may be relevant for positioning (source: @PANewsCN).
