Bond lending supports one of the core features of the marginswap ecosystem, which is leverage trading. You can supply assets used for leverage trading or borrowed by others, in this case, as an overcollateralized loan.
Bonds mature at the end of every hour and are withdrawable during the first 10 minutes before auto-subscription kicks in.
Lenders can deposit any supported asset for yield (USDC, USDT, WBTC, DAI, ETH, and more)
Bonds lenders earn $MFI and a fixed interest rate paid or compounded at maturity. Currently, the protocol supports only hourly bonds, but longer-running bonds will be available in the future.
