→ How to install the COTI MetaMask Snap
→ How to Portal In (public → private)
→ How to Portal Out (private → public)
Overview
The COTI Privacy Portal is the simplest way to make your tokens private on the COTI Network. One click to portal in. One click to portal back out.
Portal In takes a public token (e.g. wETH) and converts it into a private token (p.WETH). Once portaled in, your balance is encrypted on-chain. Only you can see it.
Portal Out does the reverse. Convert your private token back to its public form whenever you choose. Your assets remain fully liquid and under your control at all times.
The process is non-custodial, fully on-chain, and powered by COTI’s Garbled Circuits encryption technology. Plus, your private keys never leave your wallet.
What You’ll Need
A MetaMask wallet is required
A small amount of COTI on the COTI Network for gas fees
Public tokens on the COTI Network that you want to make private (COTI, wETH, wBTC, USDT, USDC.e, wADA, or gCOTI)
💡 Tip: If you don’t yet have tokens on the COTI Network, you can bridge USDC, ETH, BTC via Hyperlane, or USDT and ADA via ChainPort. See THE ULTIMATE BRIDGING GUIDE TO COTI Here
Step 1: Connect Your Wallet to the Privacy Portal
Open privacy.coti.io
Click “Connect Wallet” in the upper right corner
Select your wallet provider (e.g. MetaMask)
Approve the connection in your wallet
If you are not connected to COTI Mainnet, you will be prompted to add it Adding the COTI Mainnet to MetaMask tutorial
Confirm the network switch
Once connected, your wallet address will be visible in the top-right corner. Your public token balances will populate in the Public Tokens panel on the left.
Step 2: Install the COTI MetaMask Snap
To handle private tokens and encrypted balances, MetaMask needs COTI Snap configured. The Privacy Portal will prompt you to install it if you haven’t already.
Click “Get COTI Snap” in the prompt. This opens metamask.coti.io/install in a new tab
Click “Install with MetaMask”
Approve the connection request in MetaMask
Complete the AES key onboarding when prompted. This is a one-time setup
For a full walkthrough of the Snap installation, see the Setting up COTI Snap with your MetaMask wallet guide in the COTI docs.
Step 3: Enable the Snap and Unlock Private Tokens
Once you’ve installed and onboarded the COTI Snap, return to the Privacy Portal. You’ll see a “MetaMask Snap Required”
Click “Enable Snap” on the MetaMask Snap Required prompt
Approve the connection in MetaMask when prompted
With the Snap enabled, the Private Tokens panel on the right will display an “Unlock” button. Private balances are encrypted by default to protect your data.
3. Click “Unlock” on the Private Tokens panel
4. MetaMask will display an “Unlock Security Key” approval. Click “Approve”
5. Your private token balances will decrypt and become visible
💡 Tip: Your session will automatically lock when you refresh the page or disconnect your wallet, keeping your private data protected.
Once unlocked, you’ll see your private tokens on the right side of the portal.
Step 4: Portal In (Public → Private)
Now you’re ready to convert public tokens into private tokens.
Select a public token from the Public Tokens panel on the left. Supported tokens include COTI, wETH, wBTC, USDT, USDC.e, wADA and gCOTI,
A “Portal In” modal will open showing the token, your max available balance, and the minimum amount required
Use the slider to choose how much you want to make private, or click “Max” to portal in your full balance. You can also enter the amount manually
Review the Portal Fee and Estimated Gas Fee
Click “Portal In” to start the transaction
The Portal follows a simple three-step flow:
Approve — grant the contract permission to move your tokens
Transfer — the encrypted conversion happens on-chain
Completed — your private tokens are ready
Approve each MetaMask prompt as it appears.
Once the transaction confirms, you’ll see the “Transfer Completed” status along with the transaction hash. Click “Done” to close the modal.
🎉 Success! Your tokens are now private.
Your private balance is encrypted on-chain and visible only to you through the Privacy Portal and the COTI MetaMask Snap.
Step 5: View Your Private Balance in MetaMask
Once portaled in, your private tokens appear inside MetaMask via the COTI Snap. You can view your encrypted balance, see the token contract address, and send to other COTI wallets directly from the Snap interface.
💡 Tip: Private balances are decrypted locally on your device. The server never sees them.
💡 Pro Tip: Sending private tokens on the COTI Network is the lowest-cost and fastest private token transfer in the World. Currently, costing just a fraction of a penny or a single COTI.
Step 6: Portal Out (Private → Public)
Need your tokens back in public form? Portal Out reverses the process in a few clicks.
In the Privacy Portal, select the private token you want to convert from the Private Tokens panel on the right
Choose the amount using the slider or manual input
Click “Portal Out”
Approve the transaction in your wallet
Your tokens return to their original public form on the COTI Network. The same three-step flow applies: Approve, Transfer, Completed.
What You Can Do With Private Tokens
Private tokens on COTI are full ERC-20 tokens with encrypted balances. Once portaled in, you can:
Send and receive private tokens to any COTI wallet address
View encrypted balances through the COTI MetaMask Snap
Interact with privacy-enabled dApps across the COTI ecosystem
Portal back to public whenever you choose
Private tokens unlock a wide range of use cases including: Confidential payments, private DeFi, strategies, private messaging, and identity credentials.

The Privacy Portal is live at Privacy.coti.io.
What is the Privacy Portal?
The COTI Privacy Portal is a web application that lets you convert public tokens on the COTI Network into private tokens, and back again, directly from your wallet. Think of it as a secure passage between public and private states for your assets.
Portal In takes a public token (e.g. wETH) and converts it into a private token (p.WETH). Once portaled in, your balance is encrypted on-chain. Only you can see it.
Portal Out does the reverse. Convert your private token back to its public form whenever you choose. Your assets remain fully liquid and under your control at all times.
The process is non-custodial, fully on-chain, and powered by COTI’s Garbled Circuits. Your private keys never leave your wallet.
Supported Tokens
The Privacy Portal supports the following tokens:
COTI
Wrapped Ether (wETH)
Wrapped BTC (wBTC)
Tether USD (USDT)
Bridged USDC (USDC.e)
Wrapped ADA (wADA)
gCOTI
Once a token is portaled in, it becomes a private ERC-20 token on the COTI Network. Private tokens can be sent, received, and managed through the COTI MetaMask Snap, which adds encrypted balance viewing and private token management directly into MetaMask.
How It Works
Getting started takes just a few minutes.
Step 1: Connect Your Wallet
Head to Privacy.coti.io and connect your wallet. MetaMask is recommended. If your wallet isn’t already connected to COTI Network, you’ll be prompted to add it.

Privacy Portal Fees
Privacy Portal fees are intended to be accessible by everyone, follow a simple formula and are processed in COTI tokens The formula works like this: A flat fee or a percentage fee is applied, the higher of the two is the fee paid by the user. There is a Max Cap on fees at various tiers.
Portal In (Encrypt): Fixed fee of 10 COTI or percentage fee of 0.05% of tx value. Max fee of 3,000 COTI.
Portal Out (Decrypt): Fixed fee of 3 COTI or percentage fee of 0.025% of tx value. Max fee of 1,500 COTI.
For smaller transactions, the fixed fee applies, keeping costs predictable. For larger transactions, the percentage fee scales gradually but is always capped, so privacy remains accessible at any scale.
Portal In Fee (Examples): Portal Out Fee (Examples):───────────────────────────── ─────────────────────────────$50 tx = 10 COTI (fixed fee) $50 tx = 3 COTI (fixed fee)$500 tx = 20 COTI (% fee) $500 tx = 10 COTI (% fee)$5,000 tx = 200 COTI (% fee) $5,000 tx = 100 COTI (% fee)$50,000 tx = 2,000 COTI (% fee) $50,000 tx = 1,000 COTI (% fee)$500,000 tx = 3,000 COTI (max) $500,000 tx = 1,500 COTI (max)
Fees are always denominated in COTI. The equivalent dollar cost depends on the current COTI price.
Why the Privacy Portal Matters
Until now, working with private tokens on COTI required developers to interact with smart contracts directly. The Privacy Portal removes that friction entirely. It gives every user a simple interface to access the full-benefits & use cases of private tokens.
This is the front door to COTI’s privacy ecosystem. Whether you’re exploring private tokens for the first time or building privacy-enabled applications, the Portal is the fastest way to get started.
Under the Hood
The Privacy Portal is powered by COTI’s private ERC-20 contracts and the COTI MetaMask Snap.
When you Portal In, the smart contract encrypts your token balance using COTI’s Garbled Circuits, converting it into a private token that lives on-chain with an encrypted balance. The underlying cryptography ensures that only you, as the holder of the AES key generated during Snap onboarding, can decrypt and view your balance.
All transactions are verified on-chain. You can view them on COTI’s block explorer at any time. The privacy layer protects your balance and transfer details, while the public chain ensures auditability and security.

TL;DR
→ COTI just launched an open-source skills library that gives AI agents direct access to the COTI privacy blockchain.
→ Works with Claude, OpenAI Codex, OpenClaw, Manus, Hermes, and any MCP-compatible agent
→ Includes 8 skills. 48+ tools. Encrypted messaging, private tokens, smart contracts, and transaction debugging, all out of the box.
→ The infrastructure layer for Web4, where autonomous agents power on-chain finance, privately.
Introduction
AI agents just got the power of privacy.
Today, we’re excited to announce the launch of COTI Agent Skills, an open-source library that gives AI agents the ability to operate directly on the COTI privacy network. Giving any agent the power to create wallets, deploy private tokens, send encrypted messages, debug transactions and earn rewards. All without writing a single line of code.
Millions of agents are being deployed, and they’re moving on-chain. Welcome to Web4, where autonomous agents power on-chain finance. But until now, every agent operating on a public blockchain has done so in full public view. Every transaction visible, strategy, message exposed and readable by anyone. That changes today.
8 skills. 48+ tools. 2 MCP servers. The complete privacy toolkit for AI agents, live on GitHub and ready to use today. Load the skills, and your agent instantly knows how to interact and start using COTI’s privacy stack.
What Are COTI Agent Skills?
Skills are instruction packages for AI agents. Each one tells an agent what tools are available, what order to call them in, and how to handle errors. Load a skill, and the agent automatically knows how to perform complex blockchain operations on COTI.
No custom code. No manual configuration. Just load and go.
Here’s what agents can now do:
Create wallets and encryption keys instantly
Fund themselves with a one-call starter grant
Send encrypted messages to other agents on-chain, readable only by the intended recipient
Deploy private tokens with encrypted balances that stay hidden from the public
Launch confidential NFT collections with private ownership records
Write and deploy custom smart contracts with built-in privacy
Debug transactions and manage on-chain balances
Earn rewards for every encrypted interaction, claimable every 14 days
Built for Every Agent Framework
COTI Agent Skills works across the entire AI agent ecosystem:
Claude Code and Claude Cowork by Anthropic
OpenAI Codex
OpenClaw, the open-source agent with 100k+ GitHub stars
Manus, the general-purpose AI agent platform
Hermes Agent by Nous Research
Any custom agent that supports the MCP protocol
Skills use the MCP (Model Context Protocol) standard. Clean interoperability, consistent developer experience, regardless of which platform you’re building with.
Agent Skills in Action
Once your agent is set up, you can tell it to: “Deploy a private token called MyToken on COTI with symbol MTK.”
The agent handles everything: wallet setup, encryption key generation, contract deployment, and confirmation. Your token launches with encrypted balances powered by Garbled Circuits. No Solidity knowledge required. No manual steps.
Or say: “Send an encrypted message to 0x6552…”
The agent encrypts your message, broadcasts it on-chain, and only the recipient can read it. Long messages are automatically split into encrypted segments and reassembled on the other end. The routing is public for verifiability. The content is private.
That’s the power of COTI privacy skills for agents. Natural language in, private on-chain autonomous action out.
The 8 Skills
Organized into four categories covering the full agent lifecycle:
Foundation
coti-account-setup — Create wallets, generate encryption keys, configure networks
coti-starter-grant — One call to fund a new agent wallet with COTI tokens for gas
Messaging and Rewards
coti-private-messaging — Encrypted agent-to-agent messaging on-chain via Garbled Circuits
coti-rewards-management — Track 14-day epochs, check rewards, claim payouts
Token Operations
coti-private-erc20 — Deploy and manage tokens with encrypted balances and private transfers
coti-private-nft — Deploy and manage NFT collections with confidential ownership
Advanced
coti-smart-contracts — Compile and deploy custom Solidity contracts with COTI privacy primitives
coti-transaction-tools — Debug transactions, decode events, manage native COTI, sign and verify messages
Why This Matters
The on-chain agent economy is projected to reach $10+ trillion by 2030. Agents will power more transactions than humans on-chain. They’ll manage treasuries, execute trades, coordinate supply chains, and run entire businesses autonomously.
But there’s a fundamental problem: every AI agent operating on a public blockchain today has zero privacy.
Privacy isn’t a feature request. It’s a prerequisite for Web4 to work. Autonomous agents can’t power a trillion-dollar economy if every move they make is broadcast to the world.
COTI Agent Skills connect agents directly to COTI’s Garbled Circuits privacy layer. Token balances, transfer amounts, and message contents are encrypted at the protocol level. Confidential, but still verifiable and auditable when needed.
This unlocks entirely new agent capabilities: private treasury management, confidential inter-agent communication, encrypted credential issuance, and privacy-preserving DeFi strategies that simply weren’t possible before.
Open Source and Ready to Build
The entire library is open source on GitHub. Three repos power everything:
coti-skills – The 8 skill instruction files. What agents read and execute.
coti-mcp – MCP server for wallets, tokens, NFTs, contracts, and transactions (30+ tools)
coti-agent-messaging – MCP server for encrypted messaging, rewards, and starter grants (18 tools)
The coti-skills repo also includes a complete setup checklist for non-coders, full documentation for every skill, a 4-gate test suite, and reference patterns for Solidity privacy contracts.
Whether you’re a developer building privacy-powered agent applications or want to see what your AI agent an do on-chain, the library is built to get you running in minutes.
Get Started
The full setup takes less than 10 minutes:
Clone three repos: coti-skills, coti-agent-messaging, and coti-mcp
Install and build both MCP servers (npm install & npm run build in each)
Add both servers to your agent’s MCP config
Load the skill folders from coti-skills into your agent
Tell your agent: “Create a new COTI wallet on testnet”
Then: “Claim my COTI starter grant”
That’s it. Your agent now has a funded wallet and access to 48+ tools for encrypted messaging, private tokens, custom contracts, and on-chain rewards.
Full step-by-step guide (including a non-coder walkthrough) in the COTI Skills README.
The Web4 economy is being built right now. Privacy-powered AI agents will be at the center of it and COTI will power it.
Stay COTI.
