Tracing identity, method access and upstream authority through multi-tenant blockchain gateways.
01 / Analysis
RPC is an authority boundary
Gateways often combine public reads, expensive simulation and privileged administrative methods. Authentication must be enforced at the method and upstream identity layers.
02 / Analysis
Escalation paths
Proxy normalization, batch requests and fallback routing can bypass controls that appear correct at a single endpoint. Testing must follow the request through every hop.
03 / Analysis
Defensive architecture
Separate pools, constrained service identities, strict method allowlists and deployment isolation reduce the impact of a gateway compromise.
