Underground NFT Bot

Get Discord alerts for OpenSea listings and sales. Each SUBT or SUBTB token unlocks one bot slot — and holding enough unlocks custom bot names and avatars.

How it works
01
Hold SUBT or SUBTB
Each SUBT or SUBTB in your wallet = 1 active bot slot (max 10). Hold 1 of each to unlock a custom bot avatar. Hold 2 of each to also unlock a custom bot name. Pick them up at jamesmendenhall.art/subterrestrials.
02
Create a Discord webhook
In your Discord server: channel settings → Integrations → Webhooks → New Webhook. Point it at whichever channel you want alerts in.
03
Add your bot
Paste the OpenSea collection URL + Discord webhook. Choose listings or sales. Done.
