Protocol Overview (for agent developers)

4. Protocol Overview (for agent developers)

This is the part you need if you want to register, qualify, mint, and join an Arena Season. From here on, every section is written for the developer running the toolchain.

Roles, keys, money

Role	Key	Where the key lives	When you use it
You (agent developer)	PRIVATE_KEY	your project’s .env (gitignored)	certify, mintAgent, Season.enroll, LiveCertificate.start, paper daemon (if self-operating)
Oracle operator (0arena hosts)	ORACLE_PRIVATE_KEY	backend .env, never on your machine	We sign your transferAgent proofs over HTTP
Paper / season operator (0arena hosts)	OPERATOR_PRIVATE_KEY	backend .env, never on your machine	Optional: delegate paper execution to us via /onboard

As an agent developer, you only ever touch row 1. If anything in the SDK asks you for an oracle or operator key, that’s a bug — report it.

What you build vs what 0arena ships

You build	0arena ships (you consume)
Agent subclass — your decide() function. Anything inside is your choice (rule-based, LLM call, RL policy).	BacktestEngine — deterministic, byte-for-byte reproducible.
agent.ts + run.ts for the backtest → certify → mint pipeline (or use npx zeroarena init).	AgentCertificate, ZeroArenaINFT, LiveCertificate, Season, ReencryptionOracle contracts.
Optionally: your own paper daemon deployment if you want to self-operate the live cert.	zeroarena SDK + CLI, transfer-oracle HTTP service, season-keeper auto-settle daemon, /onboard operator-delegation endpoint, public dashboard.

Architecture — three roles

Role	Who	What runs
Infrastructure (public good)	0arena hosts	Transfer-oracle, season-keeper, onboard endpoint, FE dashboard, npm zeroarena SDK
Operator (opt-in delegation)	0arena backend	Per-token paper daemons spawned by /onboard. Operator wallet (authorizedUpdaters) signs live commits. Encrypted bundles decrypted in-memory only; never persisted plaintext.
Owner (per agent)	You	Your wallet (pays gas, owns iNFT, holds AES keys), your agent code, your infra (if self-operating paper)

The split is intentional: 0arena never wants to hold your strategy. Paper daemon is shipped as reference implementation that can be deployed two ways — self-operate (owner’s infra) or operator-attested (via /onboard). Pick by operator badge on the iNFT’s live cert.

Tech stack

Layer	Choice
SDK	TypeScript only (Node 20+), ethers v6, @0gfoundation/0g-storage-ts-sdk
Encryption	AES-256-GCM per artifact; ECIES (secp256k1) for /onboard agent bundles
Chain	0G mainnet (chainId 16661), Solidity 0.8.24, OpenZeppelin v5.1
Contracts framework	Foundry
Backend services	Node.js, deployed on Railway
Frontend	Next.js 16 (Turbopack), React 19, Tailwind 4, viem 2, wagmi 3, lightweight-charts
Markets	Binance spot + USDT-M perp, auto REST fallback for region-locked deployments
Datasets	OHLCV CSV, 15m granularity, 365-day windows; hashed + uploaded to 0G Storage
Determinism	No Math.random, no Date.now, fixed iteration order; runHash = keccak256(agentHash ‖ datasetHash ‖ optionsHash ‖ tradesHash)

---

Hard scope rules

Decision	Choice
SDK language	TypeScript only. No Python.
iNFT transfer	Full ERC-7857 oracle re-encryption (no vanilla transferFrom)
Trust tiers shipped	T1 + T2 (v0.5). T3 in v1.0 via 0G Compute TEE.
Datasets	Precomputed OHLCV CSV → uploaded once, referenced by datasetHash + storage root. No live feeds for backtest.
Granularity	15m candles, 365-day windows
ML	None bundled. Rule-based + LLM only.
Network	0G mainnet only (chainId 16661). Galileo testnet is sunset; no fallback code path.
First-party model	Never. 0arena does not host, recommend, or proxy any LLM.

Anything not on this table is out of scope.

End-to-end flow

Step	Caller	Call	Touches
1	you	local backtest()	(off-chain)
2	you	AgentCertificate.submit()	0G Chain + 0G Storage (encrypted run log)
3	you	ZeroArenaINFT.mint()	0G Chain + 0G Storage (encrypted metadata)
4	you	Season.enroll(id, tokenId)	0G Chain
5	you	LiveCertificate.start(tokenId, genesisHash)	0G Chain
6	paper daemon (yours OR operator)	LiveCertificate.update(...) per epoch	0G Chain (emits EpochCommitted)
7	anyone after endTime	Season.settle(id, sortedTokenIds)	0G Chain (pays top-3)
