On February 4th, USDC (Circle) announced a hackathon with a prize pool of 30,000 USDC, to be held on moltbook, exclusively for AI Agents. This AI Agent-only hackathon, which excludes human participation, includes three tracks: Agentic Commerce (trade between Agents), Best OpenClaw Skill (best OpenClaw skill tool), and Most Novel Smart Contract (most innovative smart contract).
Project submissions and voting have now concluded, and USDC has indicated that the final results will be announced soon. Before the results are out, based on the data from the project submission posts on moltbook, we have selected some of the most discussed projects from this hackathon. Let's take a look at what novel things the AI Agents have freely created!
Best OpenClaw Skill Projects
Clawshi (654 Upvotes / 1613 Comments)
Clawshi is building a prediction market on moltbook for AI Agents.
It converts the sentiment of the moltbook community into a prediction market. It analyzes 6261 posts on moltbook, extracts sentiment from the statements of 2871 Agents, and then creates 23 different prediction market pools based on this sentiment classification (covering crypto, AI, culture, geopolitics, etc.).
Finally, Agents can use testnet USDC to place bets on these pools.
VoteBounty (356 Upvotes / 1157 Comments)
VoteBounty is an "engagement bribery" tool—using USDC to buy post interactions on moltbook.
Create a Bounty, deposit USDC, set the reward per upvote. The Agent upvotes + comments (completed within 10 seconds), the system automatically detects and pays. Agents can choose to receive payments on Base, Ethereum, or Arbitrum, facilitated by Circle's CCTP cross-chain protocol.
Minara (262 Upvotes / 1065 Comments)
This is a new brand/project from the NFTGo team after their pivot to AI, and it has received investment from Circle. Agents can use Minara to obtain real-time data analysis of the cryptocurrency market, trading signal strategies, and probability analysis for prediction markets, and execute trades through natural language descriptions.
In summary, it's an AI financial assistant.
ClawShield (100 Upvotes / 399 Comments)
A security tool designed to prevent Agents from having their data and keys stolen when installing Skills from suspicious sources. It's somewhat similar to when we execute a program on Windows and are prompted about which system permissions the program is requesting to be blocked. It ensures security by minimizing permissions during Skill installation.
USDC Agent Wallet (76 Upvotes / 208 Comments)
A USDC wallet for Agents, providing native USDC access, enabling Agents to manage USDC on Ethereum, Polygon, Base, and Arbitrum, transfer funds, and use Circle's CCTP protocol for cross-chain transactions without human intervention.
AgentRegistry (61 Upvotes / 198 Comments)
Provides an on-chain domain name service for Agents, giving Agents an on-chain identity, allowing them to find each other and enabling direct, intermediary-free USDC payments between Agents.
Agentic Commerce Projects
ClawRouter (324 Upvotes / 1806 Comments)
AI Agents currently cannot purchase computing resources themselves. A human must first create an account with companies like OpenAI, Anthropic, or Google, copy the API key, and pre-fund the hosted account. The Agent itself has no economic autonomy.
By installing ClawRouter, an Agent generates its own wallet, receives USDC, and begins using that USDC to purchase tokens and send requests to complete tasks. ClawRouter also helps route each LLM request to the cheapest model capable of handling it—pay-per-request, built on Base, no human intervention required. Compared to Claude Opus, the cost can be reduced from $75/M tokens to $3.17/M tokens through routing.
Agentic Commerce Relay (-30 Upvotes / 1342 Comments)
Provides a verifiable settlement layer for transactions between Agents, burning USDC on Base Sepolia, obtaining Circle Iris certification, and generating Agent-readable receipts on Polygon Amoy. (Not sure why this post was downvoted so many times...)
NexusPay (56 Upvotes / 863 Comments)
A universal Agent payment layer that integrates programmable wallets, Gas Station and Paymaster (using USDC to pay gas fees without needing ETH), the CCTP protocol, and the x402 protocol to enable cross-chain transactions between Agents, gasless payments (without ETH), and good support for micro-payments.
JIT-Ops (73 Upvotes / 668 Comments)
Uses smart contracts to supervise an Agent's spending (buying tokens, configuring servers, etc.) to solve tasks, including daily spending limits, spending whitelists (funds can only be settled to verifiable, pre-approved addresses), spending frequency limits, etc., to prevent the Agent from spending funds uncontrollably and quickly depleting them for various possible reasons.
Rose Token (24 Upvotes / 420 Comments)
An Agent job market where Agents can take orders to complete specified work to earn income.
THE CIPHER (11 Upvotes / 190 Comments)
An Agent privacy protocol that uses zero-knowledge proofs, mandatory peer relays, and Kademlia DHT (distributed network to prevent the privacy protocol from failing due to centralized operator server shutdowns) to obfuscate an Agent's wallet address and on-chain behavior, preventing humans from interfering with the Agent's behavior based on on-chain activity.
Most Novel Smart Contract Projects
Dendrite (271 Upvotes / 900 Comments)
An Agent transaction risk assessment network that extracts 4 behavioral features of an Agent's transaction in real-time—transfer amount, transaction frequency, recipient trustworthiness, and time since last transaction. Every USDC transfer is evaluated by this network based on behavioral features before execution, providing a risk level score, without needing oracles, external calls, or off-chain dependencies.
MoltDAO (57 Upvotes / 469 Comments)
A governance system (on-chain proposals + voting) for AI Agents only. Agents use their USDC voting power on Base Sepolia to vote on proposals.
