HOW IT WORKS
Three steps, usually four seconds
STEP 01
Member clicks Verify
In your server, in a public channel — where everyone can see it's the real bot. No DMs, no external sites.
STEP 02
Vulcan checks their holdings
Vulcan matches them against wallets they've already proven — their OpenSea account, their PREMINT profile, or a past verification in any of 15,000 Vulcan servers — then reads holdings directly on-chain. Nothing to connect, nothing to sign.
STEP 03
Role granted, instantly
The member gets every role their holdings qualify them for — across all your rules and every chain at once.
Then Vulcan keeps watching. Real-time transfer monitoring plus scheduled sweeps re-confirm every member still qualifies. Sell the token, lose the role — automatically.
RULE TYPES
Ten ways to define who belongs
Every rule is a sentence: "if you hold X, you get role Y." Combine them freely across your roles.
Contract
Any token from a contract
The classic: hold anything from your collection's contract.
Collection
Marketplace collection
Hold anything in an OpenSea collection slug.
Quantity
Minimum quantity
Whales and stackers: require N or more tokens for the role.
Trait
Specific trait
Hold a token with a particular attribute — gold fur, laser eyes.
ERC-20
Token balance
Grant roles by fungible token balance thresholds.
Token ID
Specific token IDs
Reserve a role for exact token IDs — 1/1s, honoraries, legendaries.
Staked
Staked tokens
Count tokens even while they're locked in your staking contract.
Combo
Multiple qualifications
Require A and B together — hold both collections, or trait + quantity.
API
Custom webhook
Your own endpoint decides. Any logic you can code becomes a role.
Twitter
PFP verification
Require the member's verified NFT as their Twitter avatar.
Every rule type is available on every plan — mix and match them freely across your roles.

FAQ
Good questions
Do my members need an account somewhere?+
Usually they already have one. Vulcan recognizes wallets proven via OpenSea (the most common), PREMINT, or a past verification in any other Vulcan server — over 500,000 collectors qualify on at least one, and they verify instantly. Everyone else uses Vulcan's in-Discord flow, which still never asks for a wallet connection, signature, DM, or external link.
What happens when someone sells their token?+
Real-time transfer monitoring catches the sale and removes the role — usually within minutes, on every plan. Scheduled sweeps then re-confirm everything else: staking positions, ERC-20 balances, trait rules, API rules.
What about roles I assign by hand?+
Mark them as Protected Users and Vulcan will never remove those manually assigned roles — team roles, honoraries, and VIPs stay put no matter what their wallets do.
Can I migrate from another verification bot?+
Yes — Vulcan's migration tooling analyzes your current setup first, and no changes are made until you're certain. Because most members are already known to the Vulcan network, they re-qualify without noticing the switch.
