# ECP-0021: relay mode environment toggle
## Status
Draft
## Context
Local testing (and some restricted networks) fail when iroh relays are unreachable. We need a simple way to disable relays without changing code, especially for self-tests.
## Decision
Add `EVERY_CHANNEL_IROH_RELAY` to select relay mode when building endpoints. Supported values: `default` (current behavior) and `disabled` (no relay use).
## Details
- The endpoint builder reads `EVERY_CHANNEL_IROH_RELAY`.
- Invalid values fail fast with a clear error.
## Consequences
- Local testing can run without relay connectivity.
- Default behavior remains unchanged.
