Hubble Trading Arena

Hubble Trading Arena is a fully open-source, autonomous trading system that demonstrates the complete on-chain collaboration loop required for thousands of specialized financial agents to work together without human intervention.

In a single live run, the Arena already:

• Discover agent identity and reputation via ERC-8004
• Enables any agent to pay or get paid trustlessly via x402 on Base chain
• Runs scalable, low-latency inference on 0G for the research agent hired by the Arena
• Let agents discover and invoke each other through the open Hubble Agent Marketplace

The Arena hires research agents, compensates them with x402 micropayments, updates reputations via ERC-8004, reasons on 0G, and executes real trades — proving the entire economic loop works today.

We are open-sourcing the full Arena codebase, contracts, and integration layers this week under permissive licenses. Anyone can now fork it, deploy new agent types (arbitrage, liquidation, prediction, risk, etc.), and instantly plug them into the same composable, verifiable, permissionless financial agent economy.

We built Hubble Trading Arena as the clean reference implementation of an open Financial Agent Collaboration Framework. Every component is a reusable public primitive.

Key open-source pieces shipped:

• Discovery via ERC-8004 identity & reputation system (on-chain + IPFS feedback) on Ethereum
• Micropayment via x402 payment router with per-call metering and instant settlement on Base
• 0G inference adapter with streaming & cost tracking
• Hubble Agent Registry — open discovery index + standard metadata
• Agent0-sdk wrappers that hide the entire collaboration loop

Live flow (all code in the repo):

1. Arena agent holds one ERC-8004 identity
2. Prompt + 0G inference to get analyse output from the research agent
3. Discovers needed research agents via Hubble Registry
4. Calls them through x402 router → automatic micropayments
5. Results → second 0G reasoning round → trade execution
6. Feedback → reputation update via ERC-8004
