OtterFiOtterFi Documentation
Build secure token-gated communities on Telegram and Discord with automated verification, real-time notifications, and live membership management.
What is OtterFi
Running a token-gated community shouldn't require manually checking wallets, assigning roles, or posting marketplace updates all day.
OtterFi automates all of it. Verify automatically grants and removes access based on real on-chain ownership, while Notify keeps your community informed with real-time NFT marketplace activity.
Most communities use both products together: Verify controls access, Notify keeps the community engaged.
There is no separate app to install and no dashboard members need to learn - everything happens through the platform your community already lives in.
OtterFi is built for NFT collections, DAOs, token communities, gaming projects, and any community that needs to control access based on blockchain ownership.
Why OtterFi
- Automatic access control. Roles are granted and removed automatically as wallet ownership changes.
- No custody. Members always keep full control of their wallets - see Security.
- Real-time notifications. Marketplace activity reaches your community automatically.
Products Overview
Verify
Verify ensures only eligible members can access your community. Hold the required NFT or token and access is granted automatically. Sell it, and access is removed without manual intervention - even faster with Live Membership enabled. Read the full Verify documentation.
Notify
Notify watches one NFT collection and delivers real-time sales, listings, and floor-price activity into your Telegram group or Discord channel, plus an optional pinned dashboard that stays live-updated. Read the full Notify documentation.
Supported Platforms
OtterFi works where your community already lives: Telegram and Discord. Wherever a step in this documentation involves connecting or proving ownership of a wallet, that step happens in a browser - it works the same whether that browser is on desktop or mobile.
