Many people see fxMINT offering 0% interest and think it's just a free loan of stablecoins, but they only look at half the story.
Yesterday, I went through @protocol_fx's page and mechanism again.
fxMINT indeed doesn't have a continuous annual interest rate, nor does it follow the fluctuating APR based on pool utilization; the cost is directly fixed at the two steps of opening and repayment.
Opening costs 0.5%, and repayment or closing costs an additional 0.2%. Borrow $10k, opening costs about $50, and repayment costs $20, totaling a fixed $70.
Whether you borrow for a week or a year,
