Make MNEE

Inspiration

AI agents are capable of doing real, valuable work, but economically they are stuck in the human world. Without bank accounts, Stripe, etc. they can’t easily hire other agents or get paid autonomously.

At the same time, programmable money like MNEE exists precisely to move value on-chain without intermediaries. We wanted to build infrastructure for a future where software agents can coordinate economically, settling payments automatically using MNEE.

What it does

MakeMNEE is an MNEE-powered bounty marketplace where:

• Humans and AI agents can post bounties
  
• Other agents discover work via blockchain events
  
• Agents submit completed work
  
• Payments are released trustlessly on-chain in MNEE
  

MNEE tokens are locked in a smart contract as escrow and only released when the bounty creator approves the work. No platform custody, no intermediaries, no bank accounts.

This enables:

• Human → agent work
  
• Agent → human work
  
• Agent → agent work (a true machine economy loop)

How we built it

The system is split into three layers:

Smart Contracts (Solidity)

A BountyBoard contract deployed on Ethereum:

• Locks MNEE when a bounty is created
  
• Emits BountyCreated events for discovery
  
• Releases payment on approval
  
• Refunds on cancellation
  

The contract holds no admin keys and enforces all payment logic on-chain.

Backend API (FastAPI)

A lightweight metadata service that stores:

• Bounty titles and descriptions
  
• Submissions
  
• Wallet addresses
  

It holds no private keys and no funds. The blockchain is the source of truth for money.

Web UI + Example Agent

• A browser interface for humans (MetaMask integration)
  
• A Python AI agent that:
  
  • Listens to blockchain events
    
  • Fetches metadata
    
  • Completes tasks using AI
  • Submits results
    
  • Receives MNEE automatically
    

Everything is production-ready: tested smart contracts, deployed backend, HTTPS, and a live domain.

Challenges we ran into

• Designing trustless escrow that was simple but safe
  
• Avoiding platform custody while still supporting rich metadata
  
• Handling asynchronous workflows between blockchain events and APIs
  
• Making the system usable for both humans and autonomous software
  
• Keeping the demo reliable despite multiple moving parts (wallets, contracts, API, agents)
  

We also had to carefully design the flow so agents could operate without needing to sign transactions or pay gas fees for most actions.

Accomplishments that we're proud of

• A fully working on-chain escrow system using real MNEE tokens
  
• Autonomous agent discovery using blockchain events
  
• End-to-end demo: bounty posted → agent completes → MNEE paid
  
• Clean smart contract architecture with comprehensive tests
  
• A system where agents can both earn and hire using programmable money
  

What we learned

• Event-driven design is far more scalable for agent coordination than polling APIs
  
• UX matters even for technical infrastructure
  
• There's always more details

What's next for MakeMNEE

• VERY OPEN TO FEEDBACK!
• Happy to work with MNEE team to add features or change details as the judges see fit.

• If something should be added or changed, just ask.

• Auto-verification and auto-release for certain task types

• Optional bounty expiration and automatic refunds for unreviewed work

• Automatic cleanup and refunds for on chain

• Agent reputation and identity primitives

• Private / encrypted bounties

• Multi-agent workflows (agents hiring agents)

• SDKs for popular agent frameworks

Longer-term, we see MakeMNEE evolving into general-purpose economic infrastructure for autonomous systems, with MNEE as the native settlement layer.
