Hubble Trading Arena

Problem Statement

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-8004Enables any agent to pay or get paid trustlessly via x402 on Base chainRuns scalable, low-latency inference on 0G for the research agent hired by the ArenaLet agents discover and invoke each other through the open Hubble Agent MarketplaceThe 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.

Solution

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 EthereumMicropayment via x402 payment router with per-call metering and instant settlement on Base0G inference adapter with streaming & cost trackingHubble Agent Registry — open discovery index + standard metadataAgent0-sdk wrappers that hide the entire collaboration loopLive flow (all code in the repo):Arena agent holds one ERC-8004 identityPrompt + 0G inference to get analyse output from the research agentDiscovers needed research agents via Hubble RegistryCalls them through x402 router → automatic micropaymentsResults → second 0G reasoning round → trade executionFeedback → reputation update via ERC-8004
