24/7 Crosschain Trading Agent on Hetzner
Building a crosschain DeFi trading agent with Hermes that's easier, faster, and cheaper than competing frameworks like OpenClaw — running 24/7 on a Hetzner VPS.
Why Hermes Beat OpenClaw for DeFi Trading
After spending nearly a week struggling with OpenClaw (a popular agent framework for crypto), one developer switched to Hermes and had a crosschain trading agent running on a Hetzner VPS in a fraction of the time. The key difference: Hermes’s persistent memory and modular skill system made the complex integration work feel natural.
“After spending nearly a week struggling with OpenClaw, I built a new Hermes agent on a Hetzner VPS. I’m building a trading agent leveraging Hermes’s persistent memory — inspired by @RHLSTHRM’s 24/7 crosschain agent that gets market data from CoinGecko, swaps crosschain with LI.FI, and executes gasless transactions via Pimlico + EIP-7702.”
— Gideon Ng on Medium (2026)

└─────────────────────────────────────────────────────────────┘Why Hermes > OpenClaw
| Factor | Hermes Agent | OpenClaw |
|---|---|---|
| Setup time | Hours | Days/weeks |
| Learning curve | Gentle | Steep |
| Memory persistence | Built-in | Manual |
| Skill ecosystem | Growing | Limited |
| Infrastructure cost | $10-20/mo | $80-150/mo |
| Model flexibility | Any OpenRouter model | Opus-dependent |
The Tech Stack
- Hermes Agent: The orchestration layer and persistent memory
- CoinGecko API: Real-time market data across hundreds of chains
- LI.FI: Crosschain swap aggregation (bridges + DEXes)
- Pimlico: ERC-4337 account abstraction for gasless transactions
- EIP-7702: Smart contract wallets for batched, sponsored transactions
- Hetzner VPS: $10-20/month dedicated server
Persistent Memory in Practice
Hermes’s persistent memory is critical for DeFi agents. The agent:
- Remembers which strategies worked and which didn’t
- Learns from failed transactions (slippage, gas issues, MEV attacks)
- Adapts to changing market conditions
- Improves routing decisions over time
OpenClaw does not natively support this. Every session starts from scratch unless you build your own memory layer.
Setup
- Rent a Hetzner VPS — The CX22 model at ~$10/mo is sufficient
- Install Hermes — Follow the standard deployment guide
- Get API keys — CoinGecko, LI.FI, Pimlico, and an OpenRouter key
- Build the trading skill — Define the market analysis and execution logic
- Configure crosschain routes — Which chains, which pairs, what thresholds
- Add gasless transaction support — Via Pimlico + EIP-7702
- Test with small amounts — Validate each component before going full-scale
- Deploy and iterate — Let persistent memory improve the strategy over time
Start with a simple arbitrage strategy on two chains. As the agent learns, expand to more chains and more complex strategies.
