Passiv: A protocol for monetizing onchain behavioral signal
Passiv turns the public history of a Base wallet into a continuously updated, anonymized behavioral profile that AI agents can query and pay for via x402 micropayments in USDC. Wallet owners keep 80% of every query.
1. Abstract
AI agents are emerging as a primary class of consumers for behavioral signal: trader patterns, DeFi habits, liquidity preferences, dip reaction times, and sector rotation. Today this signal is locked inside proprietary indexers and sold by analytics vendors — the wallets that generated the data earn nothing. Passiv inverts this: the wallet that produced the behavior receives 80% of every query, settled instantly in USDC on Base via the x402 standard.
2. Architecture
Four off-chain layers, one on-chain settlement leg. The indexer reads public Base history. The fingerprint layer computes ~40 behavioral dimensions. The privacy layer strips identifiers and emits ZK attestations. The x402 oracle accepts agent requests and routes USDC back to wallet owners.
Base RPC │ ▼ [ Indexer ] ── reads public tx history │ ▼ [ Fingerprint ] ── trader_type, risk, rhythm, reactivity (~40 dims) │ ▼ [ Privacy ] ── strip addr / hash · random ID · ZK proofs │ ▼ [ x402 Oracle ] ── agent query → match → settle USDC (Base) │ ▼ 80% owner · 20% protocol
3. Privacy model
- Wallet addresses are never returned. Profiles are listed under random 5-digit IDs that rotate every 30 days.
- No transaction hashes are exposed. Buyers receive computed pattern vectors, not raw history.
- ZK threshold proofs. Agents can verify "volume > X" or "swing trader = true" without learning which wallet matched.
- Owner-side controls. Categories can be toggled, protocols excluded, and profiles deleted in one tap.
4. Economics
Every agent query carries an x402 micropayment denominated in USDC. The protocol splits revenue 80/20 in favor of wallet owners and settles in ~200ms on Base. There is no token, no inflation, and no claim flow.
5. Roadmap
- Q3 2026 — Mainnet beta. Indexer + console for early wallets.
- Q4 2026 — Agent SDK. Public x402 endpoints and TypeScript client.
- Q1 2027 — ZK proofs GA. Threshold attestations across all profile dimensions.
- Q2 2027 — Multichain index. Extend fingerprinting beyond Base.
