Robinhood Chain Collateral Haircut

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

Gated three-step chain for accepting Robinhood Chain stock tokens as collateral: tokenized-collateral eligibility, base repo haircut, then the feed-staleness / sequencer-downtime / underlying-halt haircut layer. Gate on liquidation_risk: blocked halts the chain, default proceeds to the adjusted collateral value.

STEP 3

Halt + Staleness Collateral Haircut (ART-320) →

final_haircut, adjusted_collateral_value, and liquidation_risk are the chain output.

GATE on /liquidation_risk: "blocked" → end. Default → end (adjusted collateral value stands).
