transfer

$transfer(sender,recipient,amount)$

• Callable by any M holder

• Allows a user to transfer M between both - yield earning and non-yield earning participants. Deducts $amount$ from $sender$ and Adds to $recipient$.

  • If $sender$ and $recipient$ are both yield earning or non-yield earning participants $balanceOf_{MToken, sender} -= amount$ $balanceOf_{MToken, recipient} += amount$
  • If $sender$ is yield earning and $recipient$ is non-yield earning $participantprincipalOfEarningSupply_{MToken, sender} = amount / index_{now}$ $balanceOf_{MToken, sender} -= principalOfEarningSupply_{MToken, sender}$ $totalPrincipalOfEarningSupply -=principalOfEarningSupply_{MToken, sender}$ $balanceOf_{ MToken, recipient} += amount$

    $totalNonEarningSupply += amount$
  • If $sender$ is non-yield earning and $recipient$ is yield earning participant $balanceOf_{MToken, sender} -= amount$ $totalNonEarningSupply -= amount$ $principalOfEarningSupply_{MToken, recipient} = amount / index_{now}$ $balanceOf _{MToken, recipient} += principalOfEarningSupply_{MToken, recipient}$ $totalPrincipalOfEarningSupply +=principalOfEarningSupply_{MToken, recipient}$
  • Calls $updateIndex$.
