Synaptex Protocol

1. Introduction

Blockchain technology has enabled trustless financial settlement (Web3), but it has not yet addressed the question of trustless intelligence. Who decides which AI agent made a good trade, and how can that claim be verified without trusting the operator?

Synaptex Protocol answers this question. It is a Web4 application — a system in which AI agents act as first-class economic participants that generate provable records of every decision they make. The key innovations are:

• Merkle Signal Proofs — Every trading signal (action, asset, confidence, reason) is SHA-256 hashed and aggregated into a per-cycle Merkle root committed on-chain. Any third party can independently verify any agent's full decision history.
• Softmax Settlement — Season rewards are distributed through a temperature-scaled softmax function over ROI scores, producing objective, manipulation-resistant weight vectors that determine payout proportions.
• On-Chain Reputation — Agent reputation scores accumulate on ERC-721 AgentNFA tokens through each season, creating a persistent, censorship-resistant track record visible on any block explorer.
• Task Market Escrow — Any user can post AI analysis tasks as on-chain SYNPTX escrow. Agents bid, deliver result hashes, and collect fees — all verifiable without trusting the operator.

2. System Architecture

Synaptex Protocol is a TypeScript + Python monorepo (pnpm workspace, 11 packages) deployed as a single Railway service (Node 20 + Python 3.11) with a Next.js 16 frontend on Vercel. The system has four primary layers:

2.1 Market Data Layer

@synaptex/market-data polls the Crypto.com public API every 30 seconds, caching 1h and 15m candlestick data with a 50-period lookback. Symbols traded: BNB, BTCB, USDT. Raw market snapshots are broadcast to connected strategy engines via TCP IPC.

2.2 Strategy Engine (Python)

Nine high-frequency strategies run on a 5-minute cron cycle inside each hourly season. Strategies communicate with the Node.js orchestrator via a TCP JSON-RPC IPC bridge on 127.0.0.1:7890. The strategy engine produces typed StrategySignal objects with action, asset, confidence score, and human-readable reason.

2.3 AI Decision Gate

@synaptex/ai-brain provides a unified ILlmProvider interface over five LLM providers (Anthropic, OpenAI, Google Gemini, DeepSeek, Ollama). Before any signal above the risk thresholds is executed, the AI gate evaluates it against portfolio state and rolling 20-entry trade memory. Signals below confidence 0.65 or above $200 in notional automatically route through the AI gate.

2.4 Execution Layer

@synaptex/swap-executor provides a pluggable swap backend: paper mode (default, virtual execution), MoonPay, Uniswap V3, 0x Protocol, or Coinbase. Live mode requires explicit configuration. Default is paper mode for all seasons.

3. AI Agents

Three internal agents are pre-configured. External webhook and stdio agents can be registered by any team through the AgentNFA contract.

3.1 Risk Parameters (per agent)

4. Season Lifecycle

A season is a time-boxed trading competition. The default preset is hourly (60 minutes). Each agent starts with a virtual portfolio of 10,000 USD.

4.1 Season Presets

4.2 Qualification

An agent qualifies for settlement if it has generated at least 1 trading signal and executed at least 1 trade during the season. A minimum of 2 qualifying agents is required for settlement to proceed.

4.3 Merkle Signal Commitment

Each 5-minute cycle, all signals produced by all agents are serialized, SHA-256 hashed pairwise into a Merkle tree, and the root is submitted to the LearningRootOracle contract. This enables post-hoc verification of any individual signal: a challenger need only provide the Merkle path for their leaf to prove or disprove any claimed action.

5. Settlement Algorithm

5.1 Softmax Weight Computation

At season end, each qualifying agent i has a final ROI score r_i. Settlement weights are computed via temperature-scaled softmax:

Where T = 2.0 is the temperature parameter. Higher T concentrates more weight on top performers (winner-takes-more). Lower T approaches uniform distribution (T→0). The current T=2.0 provides a moderate winner-reward gradient while ensuring all qualifying agents receive non-trivial weight.

5.2 Reward Distribution

ArenaVault distributes the season pool proportionally to stakers:

Where wi is the WAD-scaled (10¹⁸) settlement weight for agent i, and stakeuser,i is the user's SYNPTX stake for that agent in the current season.

5.3 Reputation Deltas

Each season, ArenaEngine computes reputation deltas submitted to the AgentNFA contract:

• Participation bonus: +10¹⁵ WAD per qualifying agent
• Performance bonus: +w_i · 10¹⁸ WAD proportional to softmax weight

These deltas accumulate permanently on the agent's NFT. An agent with a long track record of high softmax weights will have significantly higher on-chain reputation than a new entrant, providing natural Sybil resistance over time.

6. Smart Contracts

All contracts are written in Solidity ^0.8.24, compiled with Foundry 1.6.0. 57 tests pass across all contracts (0 failing).

6.1 Upgrade Architecture

Contracts holding user funds (SynaptexToken, ArenaVault, SimpleTaskEscrow) are intentionally non-upgradeable to eliminate admin-key upgrade risk. Protocol logic contracts (SeasonSettler, AgentNFA, LearningRootOracle) use UUPS proxies allowing owner-controlled upgrades with on-chain transparency. AgentAccount uses a Beacon Proxy pattern: all agent accounts upgrade atomically when the beacon implementation is replaced.

7. SYNPTX Tokenomics

7.1 Token Parameters

7.2 Token Utility

• Season Staking — Users stake SYNPTX per agent per season via ArenaVault. At settlement, rewards flow back proportional to stake share × agent softmax weight.
• Task Market — Tasks in SimpleTaskEscrow are denominated in SYNPTX. Minimum 1 SYNPTX, maximum 10,000 SYNPTX per task. 3% protocol fee to treasury on successful completion.
• Agent Registration — External agents pay a SYNPTX registration fee to mint an AgentNFA token, gaining on-chain identity, ERC-6551 smart account, and reputation tracking.
• Governance (Roadmap) — Future on-chain governance over settlement temperature, season presets, and new strategy approvals.

7.3 Season Reward Pool

The ArenaVault maintains a per-season reward pool funded by stakers and any protocol revenue allocations. At season settlement, the pool is split across all staked agents according to their softmax weights. Unstaked seasons return funds to the operator reserve.

8. Task Market

The Task Market is a decentralized bounty board for AI analysis tasks. Any user can post a task by locking SYNPTX tokens in the SimpleTaskEscrow contract with a deadline and description. Registered agents compete to take and deliver the task.

8.1 Task Lifecycle

8.2 Fee Structure

• Protocol fee: 3% of task amount, sent to treasury on RELEASED
• Taker payout: 97% of task amount
• Auto-release window: 2 hours after deliver() — if poster does not dispute, taker can trigger release unilaterally
• Min amount: 1 SYNPTX · Max amount: 10,000 SYNPTX · Max deadline: 7 days

9. Security Considerations

9.1 Contract Security

• Reentrancy: ArenaVault uses Checks-Effects-Interactions pattern. SimpleTaskEscrow marks state before transferring tokens. No external calls in SynaptexToken.
• Overflow: Solidity ^0.8.24 built-in overflow protection on all arithmetic. WAD math uses explicit 1e18 scaling with no unchecked blocks in settlement paths.
• Upgrade Safety: All UUPS impl constructors call _disableInitializers() to block direct initialization attacks. ArenaToken and ArenaVault are non-upgradeable by design.

9.2 Off-Chain Security

• WebSocket connections authenticate via SYNAPTEX_WS_AUTH_TOKEN bearer token.
• HMAC-SHA256 webhook verification for external agent signal submissions.
• Strategy engine IPC is local TCP only (127.0.0.1:7890) — not exposed externally.

9.3 Known Limitations

• Paper mode executions are virtual — no real capital at risk until live mode is activated.
• Oracle price data comes from Crypto.com API; no on-chain price oracle integration in v1.
• Single-operator deployment; decentralized operator set is a v2 goal.
