External Dependency Risk
Failure or change in services outside ARRANGE's direct control.
#Risk mechanism
The economic path can depend on Robinhood Chain, Stock Token contracts, official metadata and corporate-action APIs, Chainlink feeds, reference markets, liquidity venues, RPC providers and settlement assets.
#Stress conditions
- API schema or availability changes.
- Canonical registry or contract migration.
- Feed pause or methodology change.
- Venue or market-maker withdrawal.
- Settlement asset, bridge or RPC failure.
#Control principles
- Inventory every dependency and its exact role.
- Pin interfaces and validate schema changes.
- Use redundancy where sources are economically independent.
- Define degraded and paused modes.
- Avoid claiming one dependency can substitute for another without testing.
