VULCAN · ROLE INFRASTRUCTURE FOR ONCHAIN COMMUNITIES

Your Discord,
run like infrastructure.
Not like a bot.

Vulcan continuously verifies who holds what — across 27 chains, millions of wallets, thousands of servers — and keeps every role in your Discord correct. Without ever asking a holder to connect a wallet.

SAFETY DATASHEET

The only verification flow with nothing to phish

Wallet-drain scams work by imitating your verification bot. Vulcan's flow can't be imitated profitably — because at no point does a real Vulcan prompt ask for anything a scammer wants.

Roles are only ever removed for one reason: the token left the wallet. No surprises, no silent purges — your member list changes only when holdings do.

CHAINS

Wherever your community lives

27 chains, and every one gets the full toolkit — the same rules, the same real-time monitoring, nothing chain-gated.

METERING

Only role verification is metered

Not features — every plan gets the whole product, and everything that isn't role verification is free on all of them. What changes when you pay: how many members you can verify, how many rules you can run, and how often Vulcan re-checks them.

AXIS A · SCALE

Verified members & rules

The size of your setup: how many people hold a Vulcan-managed role, and how many verification rules you define. From 100 members and 3 rules on Free to unlimited on Enterprise.

1001,0005,000∞
AXIS B · FRESHNESS

Re-check cadence

How often Vulcan re-confirms every member still qualifies. Real-time transfer events stay on for everyone — the sweep is what you upgrade.

PLANS

Role verification is priced by scale. Everything else is free.

Captcha, giveaways, the sales, art and floor bots, support tickets, onboarding and the member directory don't change between plans — they're free for every server, always. Only role verification is metered.

Upgrading changes how many members you can gate and how often we re-check them — never which tools you get. And billing never touches safety: going over a plan limit gives you 30 days to upgrade or trim usage, then pauses new role grants — it never strips existing members.

FAQ

Questions, answered straight

How long has Vulcan been around?+
Since 2021, when it was launched by Adam Lizek — a prolific Ethereum developer and moderator of the XCOPY community. In 2022, PREMINT, the team behind web3's canonical allowlist platform, acquired Vulcan to put more resources behind it. Today it secures 15,000+ Discord servers and has verified 500,000+ collectors — including some of the largest NFT communities in existence.
Is it really free?+
For most servers, yes — no credit card, no trial clock. Captcha, the sales, art and floor bots, giveaways, tickets, onboarding and the member directory are free for every server, always, and no feature is locked to a paid plan. What we charge for is role verification at scale: it's free up to 100 verified members and 3 rules, then $20/month to 1,000. Roughly four in ten servers running Vulcan never reach that.
How can verification work without connecting a wallet?+
Vulcan matches members against wallets they've already proven somewhere else — their OpenSea account, their PREMINT profile, or a past verification in any of Vulcan's 15,000 servers. 500,000+ collectors are already known this way: verify once, and every Vulcan server recognizes you. Holdings are then checked directly on-chain. No connection request, no signature, no DM, no link — which means a fake bot has nothing to imitate.
I only use Vulcan for captcha (or giveaways, or the sales bot). Do I pay?+
No, and you never will. Everything except role verification is free on every plan — captcha, the sales, art and floor bots, giveaways, support tickets, onboarding and the member directory. Plans meter one thing: how many members you verify, how many rules you run, and how often we re-check them. A server that gates nobody is on Free, whatever its size.
What happens if I outgrow my plan?+
Nothing breaks, and nothing changes right away. Crossing a limit starts a 30-day window to upgrade or trim usage — the same grace period a failed payment gets — and everything runs exactly as it does now for all of it. After that, Vulcan pauses granting new roles; existing members keep theirs. Billing is never a reason a member loses a role; the only removals are security ones, like a sold or transferred token, and those continue on every plan.
What happens if a payment fails?+
Nothing breaks. Your server keeps running exactly as it is — every feature, every role — for 30 days while you sort it out. After that the service deactivates: Vulcan stops granting roles, stops removing them, and the bots stop responding. Existing roles are never stripped; they freeze exactly where they are. That cuts both ways — a sold token stops costing someone their role too, so your gate stops being enforced until you're back. Fix the payment and everything picks up where it left off.
Which chains does Vulcan support?+
27 chains: Ethereum, Polygon, Base, Arbitrum, Optimism, Blast, Avalanche, Zora, ApeChain, Abstract, Shape, Robinhood Chain, Anime, Berachain, Monad, Soneium, Unichain, Celo, Lens, Linea, Mythos, Rootstock, Scroll, Settlus, DATA Network, World Chain, and ZKsync — with ERC-20, NFT, trait, quantity, staking, and custom API rules across them. See the full chain list.
How does Vulcan's pricing compare?+
At 1,000 verified members, the going rate elsewhere is $29–$49/month — some with no free plan at all. Vulcan is $20. At 5,000 members, alternatives run $99–$449/month; Vulcan is $50. And unlike the rest, no feature is ever gated behind a tier.
Can I switch from another bot without my members re-verifying?+
That's the goal. Vulcan's migration tooling analyzes your current setup first — no changes are made until you're certain — and because most members are already known to the Vulcan network, they re-qualify without noticing anything happened. Thousands of servers have already made the move — see switching from Collab.Land.
Why does re-check cadence matter?+
Real-time transfer events catch sales the moment they happen, on every plan. The scheduled sweep is the belt-and-suspenders pass that re-confirms everything else — staking positions, ERC-20 balances dipping below thresholds, trait rules, API rules. Faster sweeps mean your roles are never more than an hour out of date.
