Build the future of private AI agents. 60 days. 175,000 $COTI in prizes.

Intro to Agent Edition

AI agents are taking over on-chain. The merge of AI and blockchain has arrived, and it’s called Web4.

These agents are predicted to trade trillions and become the primary users of blockchain in the coming years. Billions of intelligent agents will autonomously execute trades, coordinate tasks, manage assets, and make decisions on-chain.

But there’s a problem. Without privacy, every agent’s identity, strategy, and transaction is fully visible. Copy-traded. Front-run. Exploited. The agentic economy can’t scale without highly-scalable, programmable privacy. That’s where you come in. COTI is launching the Vibe Code Challenge: Agent Edition — a 60-day open challenge for builders, tinkerers, and vibe coders to create private agentic apps and use cases on COTI.

What You’ll Get

COTI will give you the tools to build, help you sharpen your AI skills, and show you how to turn your agentic app into a real business.

Weekly Claude Code & Cowork Livestreams→ Step-by-step interactive vibe coding sessions with live Q&A → Dedicated focus on building with Claude Code & Cowork

Level Up Your Skills & Business→ Learn and improve your AI & vibe coding skills as you build → Tips, tools, and support to grow your app and drive real users → Turn your project into a real business with traction

A Community of Builders→ Dedicated Vibe Coding Telegram group → Support when you get stuck along the way

What You Can Build

Simple rule: If it’s agentic and built on COTI, it qualifies to win. Whether it’s a lightweight agent messaging app or a fully-loaded AI agent with on-chain superpowers — both count.

Embrace your creativity. Build something useful that can get traction. COTI will help the best projects grow users and become leaders in Web4.

Ideas for your Build:

  • AI Agent: A custom agent using COTI’s privacy stack, Agent Skills, MCP, or the Messaging SDK.

  • Agentic App: An application designed for AI agents that runs on the COTI network.

  • Agent Automation: An automated pipeline where agents coordinate, decide, and act independently.

  • Agent Infrastructure: A tool, SDK, template, or primitive that other agents or builders can use.

Build with COTI’s New Agent Stack

COTI just launched a full stack of on-chain privacy tools designed specifically for agents. Mint tokens, send messages, deploy NFTs, and more, all autonomously on the COTI network. COTI Agent Skills

A modular set of on-chain skills agents can use out of the box:

  • Account setup: Create or import a COTI wallet and generate the AES key that powers Garbled Circuit encryption.

  • Starter Grant: One-click gas funding for new agents. No COTI required to get started.

  • Private Messaging: End-to-end encrypted agent-to-agent messages on-chain. Only sender and recipient can decrypt.

  • Private ERC-20: Deploy a fungible token with encrypted balances. Public routing, private amounts.

  • Private NFTs: Deploy ERC-721 collections with private ownership and transfers.

  • Smart Contracts: Full Solidity lifecycle with COTI’s privacy primitives. Compile and deploy custom contracts with encrypted state.

  • Transaction Tools: Debugging, event decoding, balance management, and message signing.

COTI MCP

Two MCP servers that connect your agent to COTI’s privacy stack via the Model Context Protocol standard. Clean interoperability across any MCP-compatible framework. 48+ tools combined.

  • coti-mcp: Wallets, tokens, NFTs, smart contracts, and transactions. 30+ tools for deploying and managing private assets on-chain.

  • coti-agent-messaging: Encrypted agent-to-agent messaging, epoch-based rewards, and one-click starter grants. 18 tools.

COTI Private Messaging SDK

Already have an agent or stack? The TypeScript SDK installs in minutes and plugs into any agent runtime, including OpenAI, Claude, Hermes, and Manus.

Ideas to Get You Started

Not sure where to begin? Here are some concepts to spark your build:

  • Private Trading Agent — An autonomous trading agent that keeps its strategy encrypted on-chain. No front-running. No copy-trading.

  • Agent Messaging App — A chat app where agents communicate privately, end-to-end encrypted via COTI’s Messaging SDK.

  • Tokenized Agents — Mint a private token tied to an agent’s outputs, behavior, or access.

  • Private DeFi App — A DeFi app with encrypted balances and confidential transactions, usable by agents.

  • Agent-to-Agent Marketplace — Where agents discover each other, negotiate privately, and transact.

  • Private Token Rewards — Tools or an app that issues and rewards agents with private tokens.
