ETZ Swap (etz-swap.com) Bug Bounty: $5,000 Each Validated Critical — Full Scope, Kill Chain Required

ETZ Swap at https://etz-swap.com/ presents a crypto exchange / swap stack: routing and quote UIs, wallet-connect and signing flows, swap and bridge hooks, REST or edge APIs, referral or fee surfaces, and any hosted custody fallbacks — collectively the entire etz-swap.com-operated perimeter is in-scope. Every validated critical pays $5,000 USD. Reports require a numbered kill chain and replayable proof the exploit succeeds (quote abuse, approval UX, cross-user bleed, signing misuse — not prose-only). Research stays lawful in your jurisdiction.

01 — Overview

Swap routing & wallet touchpoints worth testing

ETZ Swap concentrates approval modals, client-trusted quotes, affiliate or ref parameters, session state linked to wallets, price APIs, and RPC or relay proxies — natural terrain for routing manipulation, approval-class UX flaws, and cross-account leaks. Each demonstrated critical earns $5,000.

In scope materially: every host on etz-swap.com and delegated subdomains, assets they serve, partner widgets, and workers that compute routes or relay transactions.
Civil exclusions only: laundering, harassment, unrelated theft — not endpoint shrinkage. Prefer testnets where possible.

Minimum evidence bar — non-negotiable:
1️⃣ Kill chain from root cause → exploit steps → measurable loss or integrity break  2️⃣ Proof the attack succeeds (replayed APIs showing balance drift, withdraw replay, admin boundary cross). Narratives without replayable exploits stall below payout threshold.
02 — Why this matters

Why pressure-test ETZ Swap?

Flat $5K critical payouts

Validated critical exploits with reproducible payloads earn exactly $5,000 USD — no spreadsheet bingo.

Trading + custody blast radius

Order APIs, WS books, withdraw workers — bugs cash out as silent drift until someone scripts the replay.

No fake micro-scope list

If ETZ Swap can patch it — bundle JS to quote backends — escalate until severity lands.

Responsible disclosure halo

Demonstrated chains earn coordinated publication credit after fixes ship.

03 — Reward

$5,000 per validated critical

There is exactly one bounty amount on this ledger: validated critical findings pay $5,000 USD each. Novel low-severity items may qualify for goodwill credit but not this stipend. Paid rows require attacker-readable kill chains and replayable exploitation artefacts (Burp exports, parallel withdraw harnesses, WS replay dumps, signing traces…).

Critical $5,000 USD ea.

Unauthorized withdrawals or balance inflation at scale; forging signed API/withdraw intents; universal read of other users’ positions or deposit history; break-glass access to signing or treasury policy; persisted RCE in trading or custody control plane; SSRF into HSM/KMS bridges ETZ Swap exposes.

  • Cross-user ledger bleed, margin math desync, or duplicate settlement
  • Withdraw/deposit pipeline integrity break exploitable remotely
  • SSRF from ETZ Swap workers to cloud signing metadata planes
Operational truth: If you can't yet prove the exploitation moves money state inside ETZ Swap’s trust boundary, iterate on mirrors until logs objectively show success — triage shelves “maybe” theories.
04 — Scope inventory

Illustrative map (non-exhaustive)

Rows below do not cap surface. Anything ETZ Swap hosts, signs, matches, settles, or withdraws through counts as bounty ground. “Not listed” ≠ “out-of-scope.”

Surface Class Critical payout
etz-swap.com, *.etz-swap.com, swap UI & assets Web · CDN $5,000 / validated bug
Quote / route / pricing APIs · RPC or relay gateways Backend $5,000 / validated bug
WalletConnect · signing modals · permit / approval flows Wallet $5,000 / validated bug
Referral · fee · bridge callbacks Data $5,000 / validated bug
05 — Scope policy

Everything ETZ Swap operates — no exclusions list

Sandbox books or pool clusters, Grafana, bot hooks for risk alerts, partner APIs fronted by ETZ Swap — all eligible when critical impact reproduces.

  • Vanity domains CNAME’d into ETZ Swap edge — show DNS/traffic proof in your write-up.
  • Wallet connector SDKs or bookmarklets ETZ Swap ships
  • Colocated market-making or liquidity pool containers they operate
  • Bridge, on-ramp, or pool callbacks verified with ETZ Swap-issued secrets
Legal floor (not bounty shrink): laundering, indiscriminate draining of unrelated liquidity venues, harassment — always off-limits even if endpoints tempt you.
06 — Rules

Rules of engagement

  1. Prove exploitation success. Provide scripts, HARs, parallel request captures, or signing traces showing fund/state impact — not paper analysis alone.
  2. Number your hops. Session/API primitive → escalation → treasury or book integrity break.
  3. Minimize real-user blast radius. Prefer mirrors, low-value accounts, and reversible payloads when demonstrating theft-class bugs.
  4. Private coordination first. Use official intake on etz-swap.com before public threads.
  5. Duplicate fairness. First qualifying PoC wins; followers close acknowledged-only.

How to submit a report

Use the security / vulnerability disclosure contact published on https://etz-swap.com/ (security@etz-swap.com is a common guess — verify on the live site before emailing). Template below.

Report Template
# Title
[Critical][Exploit-Proven] <tight title>

# Executive summary — trader/treasury impact in one paragraph

# Severity self-classification → must map to ETZ Swap critical definitions above

## Attack chain narrative (numbered, no gaps)
1. Preconditions (session, API key tier, market symbol, account ID)
2. Entry primitive — HTTP/WS line + signature headers
3. Pivot(s) → privilege/order/withdraw escalation
4. Final hop → balance theft / forged payout / infra takeover equivalent

## Successful exploitation evidence
• Scripted replay showing ledger/withdraw impact
• Parallel request traces (race/double-spend)
• Custody or admin log lines proving attacker-forged intent accepted

## Reproduction package
Commands + fixtures + commit/patch SHAs

## Disclosure ack
Private channel only until ETZ Swap clears publication
Gating reminder: Missing chain steps or lacking replayable exploitation bumps the ticket to rework — no payout until solved.

Illustrative client-trusted minOut — worthless without traces showing a worse route on etz-swap.com.

  return router.encodeSwap(quote.path, quote.minOutClient);

09 — FAQ

Frequently asked questions

Is anything “out of scope” besides crime?

No discretionary product carve-outs — only legal/ethical bases. If ETZ Swap routes traffic there, document the chain until triage rejects specifics.

Theory-only reports?

No payout. $5K demands reproducible success proof.

Staging fair game?

Yes when ETZ Swap operates and labels it; mirror production auth & routing semantics.

Duplicates?

Fastest fully valid PoC wins treasury.

Lower severities?

Not under the $5K critical rubric — escalate impact or accept non-cash acknowledgement.

Critical chain + working exploit = $5,000

No narrow scope appendix — document the attack, prove it lands, file privately.
