ALL WORK
Rebuilding an internal credit platform
Complex system for credit, operations, and risk desk for booking and managing institutional loans.
ISSUE
One account per client, with trading and credit mixed together
The platform held every client on a single account, with trading, lending, borrowing, and collateral sharing one wallet. Margin was calculated at the client level, so legally separate facilities could not be isolated, and unencumbered equity inflated the ratios. Scaling a client with multiple agreements meant manual workarounds, and operations carried that complexity by hand.
SOLUTION
A segregated structure of subaccounts and pools
We built the platform around subaccounts that act as isolated credit containers, each with its own loan, collateral, and equity wallets. Subaccounts group into pools that share margin internally while staying fully segregated from every other pool. Risk is calculated at the pool level and excludes unencumbered equity, so the ratios reflect real exposure. Operations gets direct tools to move funds, close a single position without touching the rest, and reconcile balances, with every action logged.
