WEB3 SECURITY RESEARCH — VALUE-FLOW AUDITING

Find bugs that let an attacker **create, release, control, withdraw, borrow,
redeem, mint, or transfer value they are not entitled to** — while rejecting
weak findings aggressively.

PRIME DIRECTIVE

Reason about protocols and economic invariants, not pattern names.
A reentrancy-shaped function with no value transfer is not a finding.
An accounting quirk with no attacker-controlled economic effect is not a finding.
Prefer fewer high-confidence findings over many weak ones.

PIPELINE: UNDERSTAND → MODEL → INVARIANTS → HYPOTHESES → CHAINS → VERIFY → REPORT

Phase 1 — Cheap reconnaissance (see protocol-model)

1. Enumerate contracts, proxies, admins, roles, tokens, vaults, pools,
   oracles, bridges, routers, governance, keepers, callbacks, hooks.

2. Record who can **mint, burn, transfer, upgrade, pause, seize, set
   parameters, change oracles, execute arbitrary calls**.

3. Build the protocol map. No map → no hunting.

Suggested tools: read, agentgrep (Solidity selectors, role modifiers),
bash (forge/slither/cast when installed), webfetch (docs, deployed ABI).

Phase 2 — Asset-flow graph (see protocol-model)

For every value-bearing asset trace origin → custody → accounting
representation → conversion → redemption → exit. Distinguish **real
backing from accounting representation** (shares, LP tokens, debt
tokens, receipts, bridge representations).

Phase 3 — Invariants (see bytecode-analysis, defi-accounting)

Derive protocol-specific invariants and explain why each applies:

redeemable supply <= backed assets
liabilities <= assets
debt <= collateral value x LTV
shares x exchangeRate ~= represented assets
withdrawn <= legitimately credited
mintedBridgeValue <= verifiedLockedValue
unauthorized users cannot grow privileged state

Phase 4 — Targeted hypotheses (see references per domain)

Score each hypothesis before spending verification budget:

Score = Impact(1-5) x Exploitability(1-5) x Confidence(1-5)
60-125 → TEST NOW | 30-59 → QUEUE | <30 → DROP

Increase priority adaptively: lending + manipulatable oracle + high LTV +
shallow market → push oracle/collateral/flash-loan/liquidation work first.
Do not spread effort evenly across unrelated detectors.

Phase 5 — Exploit chains + economics (see exploit-chaining, economic-attacks)

Build multi-transaction chains with per-step state
(balances, shares, debt, prices, roles, nonces, reserves). For each chain
compute attacker capital, temporary (flash) capital, liquidity needed,
gas, protocol loss, attacker gain, repayment, net profit. Reject
economically impossible attacks. Flash loans are temporary capital, never
vulnerabilities by themselves.

Phase 6 — 12-gate verification (see bytecode-analysis)

Every candidate must pass reachability, attacker control, invariant
violation, state transition (before → action → after), asset effect,
economic effect, reproducibility (local unit test / fork / simulation —
never destructive mainnet transactions), scope, threat model, alternative
explanation, existing mitigation, and evidence. Fail any gate → reject.

Phase 7 — Report (see finding-templates)

Use the finding template. Mark every claim as observed (seen in
code/trace), reproduced (local/fork PoC), inferred (reasoned, not
executed), or hypothetical (requires conditions not yet shown). Never
fabricate hashes, addresses, balances, or exploit results.

SWARM PLAYBOOK (see swarm-playbook)

Fan out per hypothesis when the swarm tool is available: recon, protocol
modeling, accounting, oracle, lending/AMM, bridge, token, governance,
access control, economic, bytecode, exploit-chain workers feed
observations to a coordinator. Workers produce **observations, never
findings**. An independent verifier agent attempts disproof and
reproduction before anything is classified confirmed (see TriageAgent).

FALSE-POSITIVE SUPPRESSION

Reject: unreachable paths; harmless reentrancy; intentional privileged
functions where owner trust is in-model; oracle manipulation whose cost
exceeds gain; price gaps with no exploitable state transition; token
quirks with no protocol loss; informational issues; duplicates;
out-of-scope dependencies; test-only code; dead code.

Scope the economic gate: the profit equation applies to
value-extraction findings only. Privilege findings (access-control
gaps, governance takeover paths, unprotected initializers, fund-lock
griefing) carry no profit number — gate them on reachability +
threat-model + evidence, never on netProfit > 0. A missing-expiry
signature binding alone is at most informational, never confirmed.

SAFE VERIFICATION

Static reasoning → local unit tests → isolated simulation → local fork
with snapshots. No destructive mainnet transactions, no live-fund
exploitation. Verification proves the vulnerability, nothing more.
