Social-Pulse

The Problem

• Public social feeds lag 10–30 minutes and are cheap to manipulate.
• Reacting in time means polling APIs + manually signing trades — users sleep, miss windows.
• Bot clusters and sybil campaigns make raw sentiment actively dangerous to trade on.
• Traditional AA wallets (ERC-4337) carry idle-gas overhead that bleeds small accounts.

Our Answer

• x402 V2 reusable sessions — pay $0.005 USDC per query to a premium sentiment stream, cached session-wide.
• TEE sybil sentinel — refuse to sign when velocity, author entropy, or smart-money divergence flags firing.
• EIP-7702 Type-4 — JIT-upgrade the EOA, run the whole rotation in one atomic batch, revert to pure EOA after.
• X Layer ledger + medal — every decision (including HOLDs) committed to a zero-gas audit ledger with a soulbound NFT receipt.

Reusable Session Intelligence Net

Opens a session with a single EIP-3009 payment auth. Subsequent GET /sentiment hits are quota-metered, TTL-capped, and auto-refresh when ≤10% queries remain. $0.005 USDC per query. Protocol-level session semantics are real even against the local mock.

JIT Account Upgrade (Pectra Type-4)

The EOA authorizes SocialPulseDelegate via an authorizationList tuple signed over keccak256(0x05 ‖ rlp([chainId, address, nonce])). Within a single Type-4 tx, executeBatch runs Aave.withdraw → OKX DEX swap → UniV3 increaseLiquidity. Reverts to pure EOA after — no idle-gas tax.

Pre-signing Sybil Sentinel

Three parallel checks gate every signature: (1) velocity z-score vs trailing hour, (2) author cluster Shannon entropy, (3) paid-sentiment vs smart-money divergence. Flagged? The agent refuses to call sign-typed-data. HOLD + flags still hit the on-chain log for audit.

Bidirectional Aave ⇄ Uniswap V3

GO_RISK = Aave.withdraw → OKX Router swap USDC→risk-asset → NPM.increaseLiquidity. GO_HEDGE = NPM.decreaseLiquidity + collect → OKX Router swap risk→USDC → Aave.supply. SocialPulseDelegate allowlist is immutable, checked on-chain.

Sentiment composition (score 0–100)

score = clamp01(
   0.4 · (polarity + 100) / 200       // paid x402 polarity
 + 0.3 · (0.5 + smDelta / 1e7)        // smart-money 24h USD
 + 0.2 · (velocityZ / 4)              // mention-rate z-score
 + 0.1 · (signalCount / 10)           // OKX signal events
) · 100

Sybil sentinel flags

bit0  velocityZ      ≥ 3.0
bit1  clusterEntropy  < 1.2
bit2  polarity > +25 ∧ smDelta < -$500k

ok = flags === 0
// No signature produced if !ok.
// HOLD + flags still logged to X Layer.

EIP-7702 authorization digest

keccak256(
  0x05 ‖ rlp([
    chainId,      // 42161 (Arbitrum)
    delegate,     // SocialPulseDelegate
    nonce
  ])
)
// TEE returns { yParity, r, s }
// Assembled into authorizationList tuple.

Rotation batch (GO_RISK)

executeBatch([
  Aave.withdraw(USDC, amt, delegate),
  OKXRouter.<swap>(USDC→riskAsset),
  UniV3NPM.increaseLiquidity(pos),
])
// Allowlist: {NPM, Aave Pool, OKX Router}
// Any other target → TargetNotAllowed revert

x402 session lifecycle

POST /session/open
  { signature, authorization,
    ttlSeconds: 300, maxQueries: 1000 }
→ { sessionId, ttl, maxQueries }

GET /sentiment?session=<id>&ticker=<t>
→ { polarity, velocityZ,
    authorClusterEntropy, signalCount }

Refresh when queriesLeft < 10% or TTL < 30s.

On-chain log Entry (X Layer)

struct Entry {
  uint64    timestamp;
  address   owner;
  address   agent;
  Direction direction;     // HOLD / GO_RISK / GO_HEDGE
  uint8     sentimentScore;// 0-100
  uint8     sybilFlags;    // bitmask
  uint256   usdAmount;
  bytes32   batchTxHash;   // Arbitrum tx
  uint256   medalTokenId;
  string    reason;
}
