The OtterFi Paper

Communities built around tokens and NFTs have unlocked entirely new ways for people to organize online. Ownership can now represent membership, reputation, contribution, governance, or access itself.

Yet despite blockchain making ownership transparent, managing those communities remains surprisingly manual. Admins still check wallets by hand. Roles are still assigned manually. Members who sold their assets often keep access. Marketplace activity is scattered across websites instead of reaching the community that cares about it.

Running a token-gated community should not require constant administration. It should simply work.

OtterFi exists to make that possible.

The blockchain already records who owns what.

Ownership is information. Community is what you do with it.

The problem is that communities cannot naturally act on that information.

Every community eventually encounters the same challenges:

• Who actually owns the required NFT or token?
• Who sold yesterday but still has access?
• How do members know something important happened?
• How do admins avoid spending hours every week managing roles?
• How do communities reward their most loyal supporters?
• How do mobile users verify without frustration?

Most existing solutions automate only fragments of this workflow.

Some verify ownership. Some send notifications. Very few treat the community itself as the product.

OtterFi does.

Our vision is simple. Communities should manage themselves.

• Ownership changes should automatically update access.
• Marketplace activity should automatically reach members.
• Administrators should define rules - not repeatedly enforce them.

The blockchain should remain the source of truth. Everything else should be automation.

OtterFi consists of two independent products.

Verify

Verify automatically grants and removes access based on real on-chain ownership.

Notify

Notify automatically keeps communities informed about marketplace activity.

Together they solve two different problems. Verify decides who belongs. Notify keeps those members engaged. Most communities benefit from both. Neither depends on the other.

Blockchain ownership is unique because it is public, verifiable, and continuously changing.

Unlike a username or a subscription, ownership can change at any moment. Communities that rely on ownership therefore need software that continuously reflects that ownership.

OtterFi was built around that idea.

Ownership is not simply checked once. It becomes the foundation of community management.

Verification is not about connecting a wallet.

Verification is about proving ownership.

That distinction guided every design decision. Members can verify in whichever way they trust most.

Regardless of method, the outcome is identical. OtterFi learns only one thing:

This member controls this wallet.

Nothing more.

Access is expressed as an Access Policy - a rule, or set of rules, describing what a wallet needs to hold - and enforced across Robinhood Chain, Base, Ethereum, Polygon, Optimism, Arbitrum One, Ink, and ApeChain today, plus Solana on Pro and Premium. Read the full Verify documentation.

Communities thrive on shared moments. A rare sale. A new listing. A collection minting out. A floor moving unexpectedly.

Without automation those moments are missed.

Notify continuously watches marketplace activity and delivers meaningful events - mints, sales, listings, and floor movement - directly into Telegram and Discord, in whichever of three notification styles a community prefers.

No administrator has to watch marketplaces all day. The community stays informed automatically.

Ownership changes. Communities should change with it.

Traditional verification systems periodically check wallets. OtterFi reacts.

When Live Membership is enabled, blockchain events trigger immediate re-evaluation of community access.

The asymmetry is deliberate: a wrongly-removed member self-corrects on the very next check, but a grant made before a purchase is truly final could hand out access a reversed transaction never should have earned.

The result is a community that remains synchronized with the blockchain instead of drifting away from it.

OtterFi is designed for communities where blockchain ownership matters.

Every example below is the same underlying Access Policy engine, applied to a different community's real requirements - not a separate mode or feature.

Holder Communities

Grant access only to verified token or NFT holders.

VIP Holder Communities

Create exclusive communities for wallets that hold a minimum amount of your token or specific high-value NFTs. Whether your community calls them VIPs or "whale groups," access is always determined automatically by current on-chain ownership.

Genesis Communities

Reward early supporters with exclusive access tied to ownership of a Genesis collection.

DAO Communities

Restrict governance discussions to wallets that satisfy participation requirements.

Alpha Communities

Run invite-only trading, research, or investment groups where access is based on transparent blockchain ownership instead of manually managed member lists.

Collector Clubs

Build private communities for collectors of a specific NFT collection with membership that always reflects current ownership.

Security is not an afterthought. It is the foundation of every design decision.

OtterFi follows four principles.

• No custody. Members always control their assets.
• No private keys. OtterFi never asks for them.
• Blockchain is the source of truth. Every important decision is verified directly from on-chain state.
• Minimal data. Only the information required to manage access is stored. Nothing else.

Read the full Security documentation for exactly how this is enforced.

OtterFi is built as a platform rather than a collection of bots.

• Verify and Notify are independent products.
• Telegram and Discord are independent platform adapters.
• Verification methods are pluggable.
• Marketplace providers are replaceable.

Every component exists behind a stable interface.

This architecture allows OtterFi to evolve without disrupting existing communities. See the full Developers documentation.

Everything we build follows a small set of principles.

Automation over administration

If software can reliably perform a task, administrators should not have to.

Simplicity over cleverness

The clearest experience is almost always the best experience. Technology should adapt to people - not the other way around.

Blockchain as the source of truth

Ownership is never assumed. It is verified. Every time - a rule enforced literally in code, never trusting a trigger's own claim as fact.

Platform-native experiences

Communities should remain inside Telegram and Discord. OtterFi adapts to the platforms communities already use instead of forcing them into another application.

Trust is earned

Members should never have to wonder whether their assets are safe. Every interaction should reinforce that nothing ever leaves their wallet.

Many of OtterFi's design decisions deliberately reject unnecessary complexity.

The mobile verification flow is one example.

During development we explored WalletConnect as the universal solution across every platform. Technically it worked. The experience did not.

Our own research found no viable copy/paste-URI experience on any major mobile wallet from inside a messaging app's own in-app browser - the exact environment a Telegram member verifies from. Rather than asking members to adapt to technology, we redesigned the product around the experience we wanted them to have.

The result is a verification method - proving ownership with a tiny self-transfer, no connection required - that is simpler, more trustworthy, and easier to understand.

Throughout OtterFi, clarity wins over cleverness.

OtterFi offers a generous Free tier alongside paid Starter, Pro, and Premium tiers. Our goal is to remove friction for communities adopting token-gated access, while giving larger communities room to grow.

Paid tiers unlock deeper customization, branding, and higher limits - purchased directly through the bot with your own wallet - while keeping the core security and verification experience accessible on every tier.

We believe communities should pay for additional value - not for essential security.

OtterFi is only beginning.

Every addition will follow the same principles established in this paper.
