To initialize your validator node, you need the following parameters that define the network you’re onboarding to and the secret required for doing so. ONBOARDING_SECRET The onboarding secret provided by your sponsor. If you don’t already have one, ask your sponsor. Note that onboarding secrets are one-time use and expire after 48 hours. If you don’t join before it expires, you need to request a new secret from your SV sponsor.
DevNet-onlyOn DevNet, you can obtain an onboarding secret automatically by calling the following endpoint on any SV (replace SPONSOR_SV_URL with the SV app URL defined above):
curl -X POST SPONSOR_SV_URL/api/sv/v0/devnet/onboard/validator/prepare
Make sure to use the SV app URL (starting with sv.), not the Scan URL (starting with scan.).Note that this self-served secret is only valid for 1 hour.
