payments & asset integration.
Integrate $420, 420 Pay, swap, bridge and treasury flows using explicit settlement state, bounded approvals and fail-closed assumptions.
treat settlement as state
Applications should distinguish created, authorized, submitted, confirmed, finalized, refunded and failed payment states rather than relying on a single optimistic success flag.
minimize approvals
Request only the allowance or authority required for the intended action. Avoid broad approvals when a bounded amount, scoped permission or one-time authorization is sufficient.
verify assets
Use canonical registry and contract data to identify native and bridged assets. Symbols and display names are presentation metadata, not sufficient asset identity.
quote & expiry handling
Swap and bridge workflows should treat quotes as time-bounded inputs. Clients should revalidate amount, route, slippage, destination and expiry immediately before submission.
deployment values
Production addresses, supported bridge routes, fee schedules and package versions will be published only after qualification. Integrations should keep these values configurable.
