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;
}
}

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
ToB Grep Arsenal
# Weak Fiat-Shamir candidates (ZK verifiers)
grep -rn "keccak256\|hash\|challenge" contracts/ | grep -v "nonce\|chainId\|address(this)"
# Reentrancy: transfers before state updates
grep -rn "transfer\|safeTransfer\|call{value" contracts/ -B5 | grep -v "nonReentrant"
# Rounding direction

# Then check: is result used for deposit (round down = safe) or withdraw (round up = safe)?
# Uninitialized proxy

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 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)
