CROSSLOT

Specification · 01

Protocol overview

What CROSSLOT is designed to coordinate, and what it deliberately does not touch.

CROSSLOT is a proposed liquidity coordination protocol for Stock Token vaults on Robinhood Chain. It is designed to sit between independent liquidity vaults and the market they execute against.

Each vault holds its own mandate: allowed assets, position limits, price limits and accounting. When several vaults share an asset but need opposite inventory changes, they currently pay the external market twice. CROSSLOT is designed to exchange the compatible part internally and send only the residual outward.

Designed responsibilities

  • Collect authorized inventory intents from participating vaults.
  • Propose a batch that matches compatible opposite requirements.
  • Route the unmatched residual to an external venue.
  • Settle every authorized step atomically, or revert the batch.
  • Establish the intended liquidity positions after settlement.

Explicit non-goals

  • No issuance of underlying shares. The design uses existing secondary Stock Tokens only.
  • No use of Robinhood brokerage capital and no hedging through private Robinhood rails.
  • No custody claim on any underlying company or on Robinhood Markets, Inc.
  • No discretionary trading. A vault only ever executes what its mandate authorized.

Nothing described here is deployed. Matching and netting are established mechanisms; the proposed specialization is their application to Stock Token LP rebalancing.
