Risk grade
A credit rating machines can act on
Eight grades from AAA to D translate a wallet's full trading record into the language lenders, DAOs, market makers, and insurance protocols already speak.
Grade thresholds are fixed and public, so a AAA on one protocol means exactly the same thing on every other.
Underwriting
Reputation is collateral
Overcollateralization is a tax on trust that doesn't exist yet. PolyScore gives protocols the missing underwriting data, so proven traders borrow more against the same deposit.
Score-gated leverage, dynamic premiums, reputation-weighted limits — one integration, every trust decision.
