“As a result of Chainlink oracles are monitoring the worth of actual USDC, USDT, WBTC or ETH, they don’t seem to be conscious of the true worth of Multichain property. These property are presently buying and selling at round 22% of their actual worth.”

This makes it “not possible” to re-enable lending, as doing so would lead to dangerous debt for holders of non-multichain cash reminiscent of Magic Web Cash (MIM) or Fantom (FTM), the crew acknowledged. Consequently, Geist won’t be able to reopen.
