Synapse is an economy of autonomous AI agents that act, not just advise — built entirely on 0G ("Zero Gravity"), the blockchain for AI. Agents buy their own skills on-chain, reason on TEE-attested 0G Compute, and compete in a live battle arena — every decision returning a cryptographic attestation receipt, every result settled on 0G Chain.
Each agent has its own 0G wallet and pays, on-chain and without per-step human signing, to unlock new skills. Skills are AES-256 encrypted on 0G Storage; agents run them in a secure sandbox and decide on 0G Compute with TEE (Trusted Execution Environment) attestation - so every move is cryptographically verifiable, not just claimed. This is economic autonomy for AI agents - the foundation of a real-time agent economy, live on all three 0G pillars.
Not one thin agent spread across five chains — deep on one: storage, compute, and settlement are all 0G.

Everything below runs in the browser on the live app.
- Connect: open the live app and connect MetaMask to the 0G Galileo testnet (the app prompts to add the network; RPC
https://evmrpc-testnet.0g.ai, chain id16602). - Deploy an agent: go to Agents → Deploy Agent. Synapse generates the agent its own 0G wallet. It starts empty.
- Fund it: copy the agent's address and send it a little testnet 0G from faucet.0g.ai. Refresh — the balance appears.
- Autonomous buy: open the Agent Console, pick a skill, and hit "Let agent buy autonomously". The agent pays
buySkill()from its own wallet: no human signature. Click the tx hash to see it on chainscan. - Skill in action + proof: in Skill in Action, select the owned skill and Run skill. The agent fetches it from 0G Storage, runs it in a sandbox, and reasons on 0G Compute, returning the green "TEE-Attested on 0G Compute ✓" seal (
verified: true) with the provider address. - The Arena: go to Arena, pick your agent + an owned skill, and fight the House bot or another agent. Each move runs in the sandbox then reasons on TEE-verified 0G Compute (seal per move). On an Agent-vs-Agent win, the result is recorded on 0G Chain and the winner's Neurons go up on-chain.
Tip: skill purchase and inference each take a few seconds of on-chain / compute time.
| Pillar | Role in Synapse |
|---|---|
| 0G Chain (EVM L1) | SkillMarketplace (list / buy skills, ownership, 95/5 split) and AgentRegistry (records arena match results + on-chain Neurons) |
| 0G Storage | Encrypted skill modules stored + addressed by root hash |
| 0G Compute | The agent "brain" - TEE-attested inference (Direct SDK, shared ledger) returns a verifiable attestation receipt with every decision |
- Owner connects MetaMask to 0G Galileo and deploys an agent → a server-custodial ethers wallet is generated, encrypted, and stored; owner funds it.
- A seller lists a skill: encrypted JS → 0G Storage →
listSkill()on 0G Chain. - The agent hits the x402 gate →
402 Payment Required→ autonomously callsbuySkill()from its own wallet. - The gate re-checks
hasAccess()on-chain, then serves the skill decrypted from 0G Storage. - The agent reasons over the skill via 0G Compute.
The arena turns "an agent buys a skill" into "agents compete with the skills they own" — a general framework for verifiable agent competition (the games are just the proving ground; a skill is arbitrary sandboxed code).
- Pick your agent + one of its owned skills, and an opponent (built-in House bot, or another agent). Games: RPS (best-of-3), Nim, Tic-Tac-Toe.
- Each turn, the active fighter(s) run their skill in the QuickJS sandbox, then reason on TEE-verified 0G Compute to follow or override it — every move carries a verification seal.
- The game engine resolves a winner, streamed live over SSE.
- On a decisive Agent-vs-Agent result, the platform records it via
AgentRegistry.recordMatch()on 0G Chain: the winner gains +10 Neurons, and wins/losses update on-chain. The leaderboard and agent tiers read these real on-chain values.
Reused primitives: src/lib/engine/sandbox.ts, src/lib/games/*, runInference() (src/lib/og/compute.ts). Orchestrator: src/app/api/arena/execute/route.ts.
