FAQ

What is Vulcan? \ Vulcan is a discord-based authentication system to verify NFT ownership in your discord. You can easily grant custom roles to holders of NFTs on various contracts. We have worked with some of the top digital artists and teams including XCOPY, Proof/Moonbirds, Jadu, Memeland, AlphaCentauriKid, Lucréce, and more.

Do I need to sign in to a 3rd party site? \ No! Vulcan will never request you or your users to sign into any site other than verified marketplaces you already frequent, such as OpenSea. Users are prompted to change their bio on these sites to confirm ownership. We will never link these sites to your users, they will have to navigate to their profile themselves to avoid any impersonators and prevent middleman attacks.\ \ Vulcan Authentication's Discord ID is - 904575721429663785

Does the role automatically check ownership of a NFT? \ Yes, Vulcan automatically scans user wallets to verify ownership. If the wallet no longer holds a qualifying token, the role will be removed. Vulcan will also attempt to add qualifying roles to users. It may not be successful though depending on the complexity of your configuration or collection.

How often does the bot check registered wallets to verify current ownership? \ Transfers are monitored in real time on every plan, so a sold or transferred token usually costs the role within minutes. On top of that, Vulcan runs a full sweep of every registered wallet on a schedule set by your plan — every 3 days on Free, daily on Growth, hourly on Pro and Enterprise. Custom webhook rules are re-checked on the same sweep. Roles will not be removed from users in the Protected List.

Which blockchains are supported by Vulcan? \ Every chain, with what each one supports, is on vulcan.xyz/chains. That page is generated from the chain registry the bot itself runs on, so it is never out of date — this page used to keep its own copy of the list, and the two had already drifted apart.

Which ETH tokens are supported? \ ERC-20, ERC-721, and ERC-1155.

Why are users continually losing their roles? \ If other asset verification bots (such as Whop or Collabland) are present in the server there may be a conflict. Those bots will remove roles that they manage if they did not assign them. So it is recommend to:

  • Remove the redundant role management configurations so that only Vulcan manages the respective role(s)
  • Kick the other asset management bots.

Does Vulcan have a paid tier?\ Yes, since October 1, 2026 — but only for role verification, and only above the free tier. Captcha, the sales, art and floor bots, giveaways, support tickets, onboarding and the member directory are free on every plan, and no feature is locked to a paid plan. Verification is free up to 100 verified members and 3 rules; above that, plans start at $20/month. See Plans & Limits.

What happens if my server goes over a plan limit?\ Nothing breaks and nobody loses a role. You get 30 days to upgrade or trim usage, after which Vulcan pauses granting new roles — existing members keep theirs. A failed payment gets the same 30 days.
