First questions:

  • What if compound changes the ratio coefficient?
  • What if compound puts some vesting time to unlock comp? CF MIP from compound.
  • Who is going to run the wind and unwind?
  • What if the gas increase? Who is going to pay for the gas?
  • How do you liquidate it?
  • Risk increase with time as Compound token increase and usdc decrease. Do we apply the risk coefficient from Compound or uscd?
  • To be honest I haven’t got exactly how it works, but Comp should increase while usdc should decrease as we pay for the borrowing and get comp in exchange.
  • what happens when there is no usdc and only debt?
  • The code is relatively complex and need external call, input and output. Am I right? Looks there is a nice attack surface using compound and the wind, unwind. I feel it is another type of beast than PSM or a join token. Who is going to audit it?

Thanks to everyone participating. I really enjoy the level on these calls.
