zk-intent-fusion

ZK-Intent Fusion enables users to express complex DeFi actions in simple English – like "shift all my stablecoins to the highest 90-day yield across chains, max 3% gas" – while cryptographically guaranteeing execution integrity and privacy. The system combines four key layers: Lit Protocol’s Vincent Agent encrypts user intents with strict policies (e.g., "only allow Morpho/Optimism access under $500 for 24 hours"), ASI uAgents parse natural language into structured logic files and run solver auctions where participants compete by submitting ZK proofs of compliance with user constraints instead of revealing strategies. Avail Nexus bridges assets and executes multi-step routes like cross-chain swaps followed by lending, while Noir ZK generates dual proofs: one validating the winning solver bid met all policy checks, another confirming every execution step followed the intended path with gas limits enforced.

This architecture solves core DeFi pain points: bridging fragmentation, opaque automation, and MEV risks. Unlike existing aggregators that operate as black boxes or custodial bots requiring full asset control, ZK-Intent Fusion uses ZK proofs to let users verify both auction fairness (no fake APY claims) and execution accuracy (funds moved correctly across chains) without trusting intermediaries.

Unique innovations include privacy-preserving competitive bidding – solvers prove constraint adherence via Noir circuits without exposing algorithms – atomic scope binding preventing collateral overexposure, verifiable multi-chain orchestration, and ephemeral authorization revoking solver access post-execution. Built with Fetch.ai ASI agents for intent parsing, Lit’s threshold encryption for policy enforcement, Avail for cross-chain data availability, and Noir ZK for end-to-end correctness proofs, the system avoids single points of failure. Future phases will add zkML for generative intent expansion and non-custodial intent marketplaces.

The workflow: users type constraints → solvers bid with verifiable proofs → only qualified bids execute → ZK validates both auction rules and on-chain actions. This delivers bank-grade verification for DeFi: where traditional tools ask users to trust black boxes, this project proves every decision mathematically.

Core Tech Stack & Integration:

Avail NEXUS

Serves as the secure sequencing layer: Orders solver bids and execution steps via data availability guarantees, eliminating MEV for intent ranking. Critical hack: Bridged intent metadata (e.g., "90-day yield") into machine-readable tags using NEXUS’s modular data grids, enabling atomic cross-chain settlement without intermediate state relays. Utilized NEXUS’s light clients to verify solver deposits/withdrawals within ZK circuits via compact header proofs. ASI uAgents

NLP intent → structured logic pipeline: Homemade recursive parsers convert phrases like "highest stablecoin yield under 3% gas" into JSON constraints with cryptographic tags (e.g., {"chain": ["Base", "Optimism"], "gas_ratio": "≤0.03"}). Auctions as verifiable circuits: Solver bids submitted as Noir ZK proofs validating constraint adherence. Fleet orchestration controlled via uAgents' autonomous bidding protocols without centralized coordinators. Lit Protocol Vincent

Ephemeral key binding: User policy rules (e.g., "morpho/optimism access only under $500") encrypt solver selection criteria. Vincent enforces these policy-locked decryption keys auto-expire post-execution. Unique hack: Added gas-enforcement triggers by correlating Vincent decryption events with on-chain base fee oracles – proofs require solvers to demonstrate gas limits wouldn’t breach before decrypting bid strategies. Synergistic Workflow:

① User intents → uAgents parsing → Constraint tuple + Vincent encryption tag deposited to NEXUS

② Solver fleets submit encrypted bids meeting constraints to Vincent

③ NEXUS sequences bids & triggers decryption only after ZK proof-of-eligibility validation

④ Winning solver executes; Vincent revokes access via auto-completing policy timelines

⑤ NEXUS stores execution receipts for user verification

Key Hacks:

Constraint-Aware Encryption: Vincent policies embed parsing outputs (e.g., "for 24 hours" → epoch-bound keys) – eliminating time-bomb risks in ciphertext. MEV-Resistant Sequencing: NEXUS orders bids using commitment schemes + validity proofs, hiding ranking logic until post-settlement while ensuring front-running protection. Cross-Protocol Binding: Solvers must include circuit proofs linking executed protocols (e.g., Morpho/Aave) directly to Vincent-authorized permissions. All components Core Tech Stack & Integration:
