TRAIL OF BITS

Their Toolset

Tool	What It Does	When to Use
Slither	Static analysis for Solidity/Vyper	Always — run first
Echidna	Property-based fuzzer (write invariants, it breaks them)	Write 3-5 invariants before reading code
Medusa	Next-gen fuzzer, multi-core, parallel corpus	Deeper campaigns after Echidna
Manticore	Symbolic execution — confirms if a path is truly reachable	Specific PoC confirmation
Halmos	Symbolic unit testing — proves for ALL inputs	Math-heavy functions

Echidna Quick Start

// Write invariants BEFORE fully reading the code
contract VaultInvariants {
    Vault vault;

    // Protocol should never owe more than it holds
    function echidna_solvency() public view returns (bool) {
        return vault.totalAssets() >= vault.totalDebt();
    }

    // Share math must be consistent
    function echidna_share_math() public view returns (bool) {
        return vault.balanceOf(address(this)) <= vault.totalSupply();
    }

    // cumulativeRewardPerShare only ever increases
    function echidna_reward_monotonic() public view returns (bool) {
        return vault.cumulativeRewardPerShare() >= lastRewardPerShare;
    }
}

echidna contracts/VaultInvariants.sol --contract VaultInvariants --test-mode assertion

# With config
echidna Test.sol --contract EchidnaTest --config echidna.yaml

# echidna.yaml
testLimit: 50000
seqLen: 100
workers: 4
corpusDir: corpus/

Medusa Setup

# Install
# github.com/crytic/medusa
go install github.com/crytic/medusa@latest

# Run (coverage-guided, multi-core)
medusa fuzz --config medusa.json

# medusa.json
{
  "fuzzing": {
    "workers": 4,
    "testLimit": 500000,
    "corpusDirectory": "corpus"
  }
}

Medusa vs Echidna: Medusa is faster on large contracts due to coverage-guided exploration. Use Echidna for first pass, Medusa for extended campaigns.

Trail of Bits Audit Methodology

1. THREAT MODEL FIRST
   - What are the assets? (tokens, governance power, user funds)
   - What are the trust boundaries? (who can call what?)
   - What are the attack surfaces? (entry points, external calls)

2. STATIC ANALYSIS
   - Run Slither with all detectors
   - Examine SlithIR output for complex functions
   - Map ALL state variables and who can write them

3. WRITE INVARIANTS BEFORE READING EVERYTHING
   - "totalAssets >= totalDebt always"
   - "shares * pricePerShare == underlying always"
   - "user can always withdraw their full deposit"
   - Run Echidna. Watch it break them.

4. SYMBOLIC EXECUTION ON HIGH-VALUE PATHS
   - Use Manticore/Halmos for precise reachability confirmation
   - Confirms "can an attacker actually reach state X?"

5. MANUAL REVIEW — FOCUS ON
   - Business logic (not syntax — Slither caught that)
   - Economic invariants (is the math right under adversarial conditions?)
   - Access control (who can call what, when, with what params?)

6. DIFFERENTIAL TESTING
   - Compare against reference implementation
   - "Function A does X. Function B does the same thing differently. Why?"
   - The inconsistency IS the bug.

Key Bug Classes From Real ToB Audits

EVM / Solidity:

REENTRANCY VARIANTS (still common)
- Cross-function: lock in depositA, reenter via depositB before state update
- Cross-contract: callback to attacker contract via safeTransfer
- Read-only: view function reads stale state during reentrant call
  (Curve $70M — most underestimated variant)

ROUNDING ERRORS
- Division before multiplication: (a / b) * c vs (a * c) / b
- Wrong rounding direction (should round up for safety, rounds down)
- Precision loss in sequential operations

WEAK FIAT-SHAMIR (ZK SYSTEMS — ToB IEEE S&P 2023)
- ZK proof prover can forge proofs if transcript not fully committed
- Missing: challenge must bind all public inputs
- Check: is the verifier challenge a hash of EVERYTHING the prover touches?

ACCESS CONTROL GAPS
- Function A has onlyOwner → sibling function B does NOT
- Emergency functions callable by non-emergency roles
- Initializer called after deployment without restrictions

UNSAFE UPGRADES
- Storage slot collision between proxy and implementation
- Uninitialized implementation contract (selfdestruct vector)
- delegatecall to address from storage (attacker controls target)

SIGNATURE REPLAY
- Missing nonce in signed message
- Missing chainId in signed message
- Missing contract address in signed message

DeFi-Specific (from Uniswap, Frax, Reserve Protocol, Scroll audits):

LIQUIDITY MATH EDGE CASES
- Integer overflow at extreme tick values (Uniswap V3 type)
- Rounding direction matters at boundary

ORACLE MANIPULATION
- TWAP too short → manipulable in same block
- Spot price used directly → 1-tx manipulation

L2 BRIDGE TRUST
- Message replay across chain reorgs
- Missing sequence number validation
- Finality assumptions wrong for specific L2

The "Risk Accepted" Hunt

ToB's most valuable contribution to bug bounty hunting:

1. Find the audit report PDF for your target protocol
   (GitHub, protocol docs, "audits" page)

2. Search for "Risk Accepted" or "Acknowledged"

3. For each acknowledged finding:
   - Is the root cause still in the code? → grep to verify
   - Has any code been added AROUND the bug that creates new attack paths?
   - Is there a NEW function that has the same missing check?

4. This is valid because:
   - Protocol explicitly said "we won't fix this"
   - BUT: if new code makes it exploitable → that is a NEW bug

SLOWMIST LEARNING ROADMAP

The 4-Phase Path

Phase 1: Foundation (1-3 months)         → Solidity + EVM + Ethernaut
Phase 2: DeFi Protocols & Real Hacks (2-4 months) → AMMs, lending, bridges + reproduce hacks
Phase 3: EVM Internals + Advanced (3-6 months)    → Storage, proxies, fuzzing, first contest
Phase 4: Multi-Chain + Specialization (ongoing)   → Pick your chain + live Immunefi bounties

Phase 1: Foundation

Blockchain Basics:

Ethereum accounts, transactions, blocks, gas
Mempool: pending transactions, frontrunning mechanics
Storage: world state, Merkle-Patricia trees, slot layout

Solidity (Essential Level):

Data types, memory vs storage vs calldata vs stack
Function visibility: public, external, internal, private
Low-level: call, delegatecall, staticcall, create, create2
Assembly (Yul): inline assembly, memory layout

Key Resources:

1. Solidity docs: docs.soliditylang.org (read ALL of it)
2. Cyfrin Updraft: free courses, beginner to advanced
3. "Mastering Ethereum" — Antonopoulos (Chapters 1–7)

2. Aave V3 — aTokens, flash loans, health factor + liquidation
3. Compound V2/V3 — cTokens, borrow/supply rates
4. ERC4626 — shares vs assets, first depositor attack, rounding direction

How to Study Real Hacks:

1. Read the post-mortem (rekt.news, medium, blog)
2. Find the transaction on Etherscan
3. Trace on Phalcon/Tenderly
4. Find the PoC: git clone https://github.com/SunWeb3Sec/DeFiHackLabs
5. Run it: forge test -vvv --contracts src/test/YEAR-MONTH/HackName_exp.sol
6. Add comments explaining every line

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

Permission surface may require sandboxing
Financial research output is not financial advice; require human review before any live investment decision
Potential broker, wallet, exchange, or real-money execution surface; sandbox and explicit approval are required
Financial research output is not financial advice; require human review before any live investment decision.

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
