Building scalable applications with backend wallets

Blockchain and artificial intelligence are converging in groundbreaking ways, with **onchain AI agents** emerging as a transformative force in decentralized finance (DeFi), gaming, and digital asset management. These autonomous programs combine AI’s decision-making prowess with blockchain’s transparency, enabling 24/7 trading, yield optimization, and even social media engagement—all without human oversight. This article explores how onchain AI agents work, their real-world applications, and why they’re poised to redefine crypto’s future.  

## What are onchain AI agents?

Onchain AI agents are **self-operating programs** that execute tasks on a blockchain, governed by smart contracts and machine learning models. Unlike traditional AI, these agents:  
- **Control crypto wallets**, enabling them to buy, sell, or stake assets autonomously. 
- **Leverage oracles** to integrate offchain data (e.g., social sentiment, price feeds).  
- **Operate transparently**, with every action recorded onchain for auditing .  

For example, an agent might analyze Twitter trends to identify rising memecoins, then execute trades using predefined risk parameters—all while updating users via Discord. This blend of autonomy and accountability makes them uniquely suited to crypto’s fast-paced markets.  

## AI agents architecture

Onchain AI agents operate through a combination of smart contracts containing their core logic and instructions, and crypto wallets they control to execute transactions[1]. These agents typically follow a four-step process: perception, input processing, decision making, and action[2]. They gather data from the blockchain and external sources, analyze it using machine learning algorithms, make decisions based on their programmed goals, and then execute actions such as trading or deploying smart contracts.

Key components of onchain AI agents include:

* Smart contracts defining the agent's logic and objectives
* [Controlled crypto wallets](https://www.openfort.xyz/docs/guides/server/dev) for transaction execution
* Access to oracles for off-chain data
* Integration with AI models like large language models (LLMs)
* Connectors for interacting with platforms like social media

Advanced onchain AI agents can perform complex tasks autonomously, such as launching tokens, creating liquidity pools, and even controlling their own private keys for enhanced sovereignty. As the technology evolves, these agents are becoming increasingly capable of making sophisticated decisions and executing complex strategies in the decentralized finance ecosystem.


## 5 key benefits of onchain AI agents

1. **Hyper-Efficiency**  
   - Execute trades in milliseconds, capitalizing on arbitrage or price discrepancies humans might miss.  
   - Optimize gas fees by bundling transactions or timing operations during low-network congestion.  

2. **24/7 Market Monitoring**  
   - Track metrics like lending pool APYs, NFT floor prices, or memecoin social volume nonstop.  

3. **Democratized Access**  
   - Platforms like **ai16z** and **ElizaOS** let users create agents via natural language, bypassing coding expertise .  

4. **Cross-Platform Synergy**  
   - Manage portfolios across Ethereum, Solana, and Cosmos simultaneously, rebalancing based on cross-chain trends.  

5. **Community-Driven Growth**  
   - Agents like **Griffain** gamify participation, rewarding users who contribute data or liquidity to their strategies .  

## Use cases reshaping crypto 

### **1. Autonomous trading & portfolio management**  
Agents like **Kaito** analyze onchain whale activity and CEX order books to execute trades. For example:  
- **Trend Following:** Buy tokens trending on DexScreener.  
- **Arbitrage:** Exploit price gaps between Uniswap and Coinbase.  
- **Risk Mitigation:** Auto-sell if a token’s social sentiment drops 30% in an hour .  

### **2. DeFi yield optimization**  
Agents maximize returns by:  
- Shifting stablecoins between Aave, Compound, and Morpho based on real-time APYs.  
- Providing liquidity to volatile pools only during peak fee periods.  

### **3. Memecoin launches & marketing**  
Projects like **Bankr** use AI agents to:  
- Mint and promote tokens via Twitter/X bots.  
- Airdrop to influential accounts detected by sentiment analysis tools.  

### **4. Onchain gaming**  
- **NPCs with Agency:** AI-controlled characters in games like **Holoworld** trade in-game assets or form alliances.  
- **Auto-Farming:** Agents grind for rare NFTs while users sleep.
