This simple client‑side check verifies that your browser can reach common relay domains. It is not a substitute for full relay health. Always measure inclusion and maintain conservative fallbacks.
| Relay | URL | Status |
|---|---|---|
| Flashbots Relay | https://relay.flashbots.net/ | — |
| Eden Network (example) | https://api.edennetwork.io/ | — |
| Blocknative (example) | https://api.blocknative.com/ | — |
Tip: keep a fallback path (public PGA with tight caps) in case private delivery is unavailable. See private vs public.
