FATHOMHOOK v2.0 // SOUNDING INFRASTRUCTURE
Multi-Engine Depth Sonde

Depth-BasedSecurity Auditfor Autonomous Agents

Autonomous agents operate with wallet access and critical permissions. Fathomhook lowers a multi-engine sonde to measure exact risk depth (0–100) via static bytecode decompilation, Louvain Sybil cluster graphs, and x402 payment receipts.

ENGINE 1 // STATIC (40%)
Heimdall & SWC Detectors
ENGINE 2 // BEHAVIOR (30%)
Louvain Sybil Clusters
ENGINE 3 // PAYMENT (20%)
x402 EIP-3009 Receipts
CONSENSUS // PROOF (10%)

The Sounding Descent

Lowering the probe through 5 distinct verification depths to measure exact vulnerability resistance.

[00 FATHOMS]EVM Bytecode Stream

Surface Ingestion & Disassembly

Ingests raw EVM bytecode directly via RPC nodes, extracts memory layouts, and resolves 4-byte function selectors.

100% Real-Time Bytecode Ingestion
[25 FATHOMS]Engine 1 (Weight 40%)

Static & Semantic Vulnerability Classifier

Executes Slither AST patterns combined with Gemini AI semantic evaluation to uncover Reentrancy (SWC-107), Access Control (SWC-105), and dangerous delegatecalls.

90+ SWC Vulnerability Classes
[50 FATHOMS]Engine 2 (Weight 30%)

Louvain Sybil & Behavioral Graph

Builds address transfer graphs to measure inter-funding rhythm, transaction timing density, and coordinated bot swarms using DeepSybil dynamic graph learning.

Louvain Community Cluster Metric
[75 FATHOMS]Engine 3 (Weight 20%)

x402 Economic Anchor Verification

Validates genuine economic activity by checking gasless EIP-3009 USDG transfer receipts and counting unique payer diversity ratios.

EIP-3009 Gasless Receipt Verification

Consensus Synthesis & Permanent IPFS Seal

Synthesizes multi-engine scores within 10-point tolerance, generates cryptographically tagged report, and pins CID permanently to Pinata IPFS.

Policy Framework // Governance

Risk Tiers & Agent Action Policies

How autonomous protocols translate Fathomhook depth scores into programmatic risk-mitigation rules.

00 – 20auditPass
Low Risk Depth
Policy: Instant Full Authorization

Safe for autonomous wallet operations, automated DEX interactions, and unconstrained task execution.

21 – 50review
Medium Risk Depth
Policy: Multi-Sig & Spending Cap

Moderate permission vectors detected. Recommended strict daily gas limits and multi-signature authorization.

51 – 80caution
High Risk Depth
Policy: Sandboxed Quarantine

Elevated risk depth. Direct wallet access restricted. Must execute inside isolated virtual sandboxes.

81 – 100critical
Critical Exploit Risk
Policy: Automated Circuit Breaker

Dangerous exploit vectors or severe Sybil bot clustering detected. Immediate blacklisting across protocols.
