EVM X-Ray Stepper (OllyDbg Reverse Engineering Console)
Deterministic Solidity bytecode execution trace debugger. Line-by-line opcode stepping, symbolic storage slot decoding, and ghost invariant verification.
// Euler Vault - donateToReserves invariant checkfunction donateToReserves(uint256 subAccountId, uint256 amount) external { AssetStorage storage d = getAssetStorage(); uint256 balance = d.underlyingBalance; // VULNERABILITY: Internal reserves credited without liquidity health check d.reserves += amount; subAccount[subAccountId].eTokenBalance -= amount; // Missing: checkLiquidity(subAccountId)! require(subAccount[subAccountId].dTokenBalance >= 0, "SOLVENCY"); emit Donate(subAccountId, amount);}function checkInvariant() public view returns (bool) { return totalAssets() >= totalBorrowed() + totalReserves();}Step through execution using F10 (Next) or F11 (Into) to observe storage mutation and invariant evaluation.
The 4 Pillars of ChainForge PRO
How ChainForge PRO replaces blind, multi-hour fuzzing loops with surgical, deterministic reverse-engineering and zero-egress local caching.
Deterministic Bytecode & Storage Layout Replay
Replaces thousands of lines of chaotic raw Foundry logs with a 4-pane reverse-engineering console. Maps compiler artifacts to decode raw 32-byte hex slots into symbolic variables (totalSupply, balances[victim]), tracks ghost variables across execution frames, and allows auditors to step line-by-line using F10, F11, and breakpoint traps. Includes God Mode for in-memory PyREVM state overrides to bypass shallow guards.
Persistent Anvil Mainnet Fork + eRPC Redis Cache
Fuzzing 100,000 multi-transaction sequences against live Ethereum state normally exhausts millions of RPC credits. ChainForge executes against an isolated Anvil fork pinned to an exact historical block height, proxied through an eRPC caching layer. After initial fork hydration, 100% of state reads hit local memory—enabling 50+ deep scans per day at $0 upstream RPC cost. Vanguard sequential hydration pre-warms cache slots to prevent container stampedes.
5 Deterministic Static Code Detectors
Before launching a single Docker worker, Phase 1.5 runs 5 deterministic AST analyzers in sub-second latency with zero external LLM or API dependencies: (1) Parameter Flow Tracer for msg.value forwarding mismatches, (2) Unchecked Return Accountability, (3) Balance Gap Detector between internal ledgers and raw balances, (4) DeFi Pattern Matcher across 10 structural primitives, and (5) Cross-Contract Call Mapper.
Codified Exploit Invariants + Z3 SMT Prover
Encodes 103 formal invariants distilled from historical exploit mechanics (Euler, Nomad, Mango Markets, Curve). An 8-component scoring gate filters candidates down to 8–20 high-signal tests. For 12 mathematical invariants, Halmos symbolic execution backed by the Z3 SMT solver turns trial-and-error iterations into mathematical proofs of correctness. Prove Lab then converts invariant breaches into Immunefi-ready forensic reports.
