Collateral Management

Post collateral. Any hour. Any day.

Post margin in USDC anytime 24/7. Collateral mobility when risk requires it, not when banks open up.

Benefits & features

Risk is real-time. Your collateral should be, too.

Meet every margin call exactly sized, the moment it's required.

Act the moment risk is involved

Respond to a margin call or a position shift right away, regardless of banking hours.

Deploy capital efficiently

When collateral moves 24/7, clearinghouses can recalculate risk more often and reduce how much you have to post.

Reuse collateral immediately

When a position closes, USDC lands back instantly. Deploy it again the moment it's freed.

Futures

A future where collateral moves as fast as the market does

When markets break at 11 pm on a Friday, collateral can move just as fast. Exposure can be recalculated instantly, and the clearing member delivers USDC to the clearinghouse in seconds for exactly what's owed.
