Examples

Please note that WETH and ETH will be used interchangeably in the following discussion.

The b0x network allows anyone with ERC20 tokens to loan it out for interest on a margin trading platform.

Example 1: Alice holds a lot of ETH tokens and instead of letting it sit, she wants to lend it to traders who are looking to borrow money so that they can trade on margin. Alice creates a b0x order specifying the type of token she is lending out (i.e. loanToken) and the type of token that she wants the interest to be paid in (i.e. interestToken).

The lender can specify the specific margin amounts that the borrower must have in order to fill the order and maintain the loan.
