# Stormbit

Structured options-backed credit. Borrowers take USDC loans against BTC or ETH at 0% APR — each loan settles on a listed option expiry, with no liquidation along the way. Lenders fund those loans and earn the option premium each loan generates — yield priced at origination, paid from inside the trade.

{% tabs %}
{% tab title="Lenders" %}
Deposit USDC, receive soUSD. Yield comes from the call premium written on every loan's collateral — priced at trade entry, uncorrelated to Fed rates. Tenors with a floor mechanism.
{% endtab %}

{% tab title="Borrowers" %}
Post BTC or ETH, receive USDC. 0% APR, settled at the expiry you choose, no liquidation. The trade-off is explicit: your upside is capped at the call strike until settlement.
{% endtab %}

{% tab title="Deals" %}
Buy discounted collateral from expired loans. Dutch auction — price drops over time, first buyer wins.
{% endtab %}
{% endtabs %}
