TL;DR

• MetaMask Snaps let you add custom features to your MetaMask wallet.
• The COTI Snap allows users to onboard COTI accounts, encrypt/decrypt tokens and NFTs, and interact with COTI dApps.
• It brings privacy smart contracts directly into MetaMask, making COTI V2 easier to use.
• Snaps run in isolated environments with strict permissions, designed to keep user assets safe.
• This marks a major step toward private finance at scale, powered by COTI V2.

MetaMask is one of the most widely used crypto wallets in the world. For years, it's been the go-to tool for connecting to Ethereum and other EVM-compatible chains. But MetaMask has been limited in scope-mainly focused on Ethereum-based activity.

That changes with MetaMask Snaps. Snaps are third-party applications built to plug into MetaMask. Think of them as extensions-like browser add-ons-but for your crypto wallet. A Snap can expand MetaMask's functionality, from showing deeper transaction insights, to sending notifications, to connecting with blockchains outside Ethereum.

For users, it's about personalization. You're no longer limited to what MetaMask ships by default-you can shape the wallet to your needs.
For developers, Snaps open the door to build new tools, including direct integrations with networks like COTI.

How Snaps Work

At their core, Snaps are JavaScript programs that run in an isolated (sandboxed) environment. They can't interact with your wallet without permission. When you install a Snap, MetaMask will show a list of permissions it requires. This could include things like accessing the internet, showing a custom screen, or storing encrypted data locally. You decide whether to approve.

It's similar to how installing a mobile app works-you grant certain permissions and the app delivers its features. MetaMask emphasizes that Snaps are permission-gated, meaning they cannot access your assets unless you explicitly allow it. Even so, users should always read permissions carefully before enabling one.

Currently, Snaps can only be installed through the MetaMask browser extension (not mobile), and they're available via the official MetaMask Snaps Directory.

Why Snaps Matter for Web3

Until now, MetaMask has primarily been an Ethereum-first wallet. Adding other chains meant manually inputting network details, and even then, only EVM-compatible networks were supported.

Snaps break that barrier. They allow MetaMask to natively connect with non-EVM blockchains, add entirely new utilities, and offer notifications or transaction warnings. In effect, Snaps transform MetaMask into a multi-chain, multi-function hub for Web3.

This is where COTI V2 enters the picture.

The COTI MetaMask Snap

The COTI Snap is a custom integration designed to bring COTI accounts and privacy features directly into MetaMask.

With the Snap installed, users can:

• Onboard COTI accounts seamlessly.
• Encrypt and decrypt tokens or NFTs stored on-chain.
• Connect with COTI dApps directly from their MetaMask.

In practice, it means COTI's privacy infrastructure is just a click away, integrated into a wallet millions already use.

For COTI V2-focused on building privacy-preserving smart contracts and compliance-ready confidentiality tools-the Snap lowers the barrier to entry. No clunky setups, no new wallets to download. Just MetaMask plus the COTI Snap.

Why It Matters for COTI V2

COTI V2 is all about solving a fundamental problem in crypto: how to enable private finance without breaking compliance. Most privacy coins lean toward extremes-either totally anonymous (raising regulatory concerns) or fully transparent (sacrificing user privacy). COTI V2 introduces a middle ground called selective disclosure. Users can decide what information to reveal and when, ensuring privacy without ignoring the law.

As COTI CEO Shahaf Bar-Geffen has put it:

The Snap makes these ideas practical and accessible. Instead of imagining how privacy finance works, users can test it themselves inside MetaMask.

Key Features of the COTI Snap

When you install the Snap, MetaMask will request permissions that unlock its features. These include:

• Internet access to handle requests.
• Dialog popups for user approvals.
• Custom screens for COTI-specific actions.
• Secure storage of encrypted data.
• Direct communication between websites/dApps and the COTI Snap.

After onboarding, you'll generate an AES key-a cryptographic key that lets you encrypt and decrypt data on the COTI network. This key is as sensitive as your wallet's private key and must be treated with the same level of care. Once set up, you can explore COTI's privacy dApps, interact with smart contracts, or build your own integrations if you're a developer.

Why does this matter beyond just MetaMask?

Because it's about adoption. Privacy tech only works if it's easy to use. By embedding into a wallet millions already trust, COTI avoids the "new wallet fatigue" that has limited many crypto projects.

This integration also sets the stage for developers. With the Snap, they can integrate COTI V2 privacy features into their own dApps without reinventing the wheel. That means more tools, more apps, and more ways for users to experience private finance in action.

As Web3 matures, privacy won't be optional-it will be a requirement. Whether for individual protection or regulatory compliance, users and institutions alike need ways to transact privately while maintaining accountability. COTI's MetaMask Snap is an early glimpse of that future.

Final Thought

Crypto has always promised financial freedom. But freedom without privacy is incomplete. The COTI MetaMask Snap makes privacy practical-accessible to anyone who already uses MetaMask, no new hoops required.

As COTI V2 continues to push privacy finance forward, this integration shows how cutting-edge tech can meet users where they are. Simple, usable, and powerful-the kind of progress that turns vision into reality.
