Builds the
The sweep pays whatever is booked when it mines, which can exceed the amount quoted when the calldata was built. A confirmed sweep is recorded on the market as an
Confirming with
sweepInfrastructureFees transaction, which pays everything the market has booked as Trusset’s infrastructure fee to the Trusset wallet. That wallet is a constant in the market contract, 0x65FF3a731366472d40CF458332457403168c2BEA, and the market has no setter for it.
Any wallet may sign, and nothing reaches the signer. The sweep only moves money that is already booked to Trusset. Until it runs, that money sits on the market as a liability that is never lent out and that no liquidity provider can withdraw.
The booked balance has two sources. Trusset takes 15 percent of repaid interest and of interest recovered through liquidation, and 87 percent of every fixed transaction fee. Get Cashflows itemises both.
