- [On-Chain Destiny Bureau](https://manyaitool.com/products/destiny-bureau) - [md](https://manyaitool.com/products/destiny-bureau/index.md): A daily reading so you never choose wrong — on-chain mysticism, 'scientific' fortune-telling.
- [DuoLaSafe — Web3 Security Audits & Forensics](https://manyaitool.com/products/duolasafe) - [md](https://manyaitool.com/products/duolasafe/index.md): Smart-contract audits, on-chain forensics and asset-recovery support — every report public, PoC-backed, with an adversarial ruled-out section.
- [Stolen-Fund Tracer — where did the money go?](https://manyaitool.com/products/safecheck-trace) - [md](https://manyaitool.com/products/safecheck-trace/index.md): Paste a hacked address and trace the funds hop by hop. Our in-house intel DB labels every hop — and pinpoints when the loot lands in an exchange deposit address (a freezable endpoint) or hits a mixer (trace breakpoint). The first concrete step toward recovery, free.
- [Wallet Approval Checkup — who can drain you?](https://manyaitool.com/products/safecheck-approvals) - [md](https://manyaitool.com/products/safecheck-approvals/index.md): Most thefts trace back to one forgotten approval. Scan a wallet (read-only) for every live token approval and flag the unlimited ones — plus whether the spender is a known drainer / malicious contract, cross-checked against DuoLaSafe's intel DB and a multi-source risk engine. The part Revoke.cash won't tell you.
- [Token X-ray — honeypot & rug deep check](https://manyaitool.com/products/safecheck-xray) - [md](https://manyaitool.com/products/safecheck-xray/index.md): Paste any token contract for a real on-chain check: honeypot buy/sell simulation, taxes, mint/freeze powers, proxy upgradability — plus deployer reputation against DuoLaSafe's intel DB (the serial-rugger signal generic scanners miss). Green / yellow / red at a glance; known stablecoins won't false-positive.
- [Is this real USDT? — Stablecoin authenticity check](https://manyaitool.com/products/safecheck-token) - [md](https://manyaitool.com/products/safecheck-token/index.md): Paste any token contract and check it against an all-chain official-stablecoin registry plus our in-house fake-stablecoin blacklist. Address matches official = real; matches our blacklist = scam. Catches counterfeit USDT/USDC — especially on TRON, where most fakes live. Nobody else fuses official-address registry + honeypot + scam intel into one verdict.
- [Wallet drained? — Free self-rescue triage wizard](https://manyaitool.com/products/safecheck-sos) - [md](https://manyaitool.com/products/safecheck-sos/index.md): A free triage wizard for theft victims: it works out how you were hit, gives prioritized stop-the-bleed steps, flags the attacker address against our intel DB, and auto-generates pre-filled IC3 / Chainabuse / police / exchange-freeze reports. Read-only, Chinese-first, and it never asks for your seed phrase — unlike the recovery scams that prey on victims.
- [Is this a phishing site? — Domain check + free API](https://manyaitool.com/products/safecheck-phishing) - [md](https://manyaitool.com/products/safecheck-phishing/index.md): Check any domain against DuoLaSafe's 820k+ phishing & malicious domains, with parent-domain matching. Free, real-time, open API with no key — wallets and dApps can plug in directly. Undercuts the $999/mo, deliberately delayed commercial blacklists.
- [Polymarket $2.9M fund-tracking investigation](https://manyaitool.com/products/polymarket) - [md](https://manyaitool.com/products/polymarket/index.md): A frontend supply-chain attack drained ~$2.9M from 11 users. The press said the funds still sit in the consolidation wallet — we traced the chain: already moved, split and idle across 3 wallets, plus the address-poisoning targeting the loot. A verifiable, dated on-chain snapshot.
- [Verus bridge $11.58M post-mortem](https://manyaitool.com/products/verus-bridge) - [md](https://manyaitool.com/products/verus-bridge/index.md): The bridge's submitImports never enforced cross-chain amount conservation; $11.58M drained, swapped to 5,402 ETH. A full 7-section root-cause + attack-tx breakdown with fund tracing: reported as "funds unmoved," yet on-chain the loot split out (4,052+1,350 ETH) just 3 days later and the wallet was empty by Jun 27.
- [Humanity Protocol $36M analysis](https://manyaitool.com/products/humanity-protocol) - [md](https://manyaitool.com/products/humanity-protocol/index.md): Not a contract bug — a fake multisig: the 7 keys controlling the token and bridge were all backed up on one developer's laptop, and a single Bithumb-spoofing phishing email took the lot, moving ~447M $H across ETH/BSC. A 7-section root-cause + attack-flow breakdown; Quantstamp attributes it to DPRK.
- [Bybit $1.5B — the largest hack ever](https://manyaitool.com/products/bybit) - [md](https://manyaitool.com/products/bybit/index.md): Lazarus tampered Safe{Wallet}'s frontend JS, swapping a cold-wallet transfer for a DELEGATECALL that replaced the implementation and drained the vault. We verified on-chain that the Safe's slot0 still points to the malicious contract. A 7-section breakdown.
- [KelpDAO $292M bridge hack](https://manyaitool.com/products/kelpdao) - [md](https://manyaitool.com/products/kelpdao/index.md): A 1-of-1 LayerZero DVN was poisoned via compromised RPC nodes + DDoS failover, forging a phantom source-chain burn to mint 116,500 unbacked rsETH. We verified the mint tx, GUID, Tornado funding and Arbitrum freeze. Attributed to Lazarus.
- [Drift $285M access-control takeover](https://manyaitool.com/products/drift) - [md](https://manyaitool.com/products/drift/index.md): Not a contract bug: attackers spent 6 months social-engineering into the Security Council via a fake trading firm, weaponizing Solana durable nonces to pre-sign admin transfers and drain vaults with fake collateral. Attributed to DPRK.
- [Resolv $25M KMS key compromise](https://manyaitool.com/products/resolv) - [md](https://manyaitool.com/products/resolv/index.md): Resolv's AWS KMS signing key was compromised, minting 80M unbacked USR from ~$100K USDC via two completeSwap calls and cashing out ~11K ETH. Root cause: a single off-chain key plus no on-chain mint cap. On-chain verified.
- [Truebit $26.2M integer overflow](https://manyaitool.com/products/truebit) - [md](https://manyaitool.com/products/truebit/index.md): A legacy purchase contract (Solidity 0.6.10, no overflow checks) overflowed its pricing math; a huge input wrapped the price to ~0, letting the attacker mint TRU for free and drain 8,535 ETH in one tx. Attack tx and overflow math both verified on-chain.
- [Moonwell oracle misconfiguration](https://manyaitool.com/products/moonwell-oracle-misconfiguration) - [md](https://manyaitool.com/products/moonwell-oracle-misconfiguration/index.md): An oracle update dropped the ETH/USD leg of cbETH pricing, mispricing cbETH at ~$1.12 vs ~$2,200; liquidators seized 1,096 cbETH for ~$1 each, leaving ~$1.78M bad debt. One missing price leg = real money.
- [Cetus $220M AMM overflow](https://manyaitool.com/products/cetus) - [md](https://manyaitool.com/products/cetus/index.md): Sui's largest AMM: a wrong overflow mask in checked_shlw (0xffff…<<192 vs 1<<192) let a u256 left-shift silently truncate, minting ~1.03e34 liquidity for ~1 token to drain reserves. ~$220M lost; ~$162M frozen by validators and returned via governance.
- [GMX V1 $42M reentrancy](https://manyaitool.com/products/gmx-v1) - [md](https://manyaitool.com/products/gmx-v1/index.md): Arbitrum perp DEX: a reentrancy via the executeDecreaseOrder callback skipped the globalShortAveragePrices update, crushing BTC short avg price and inflating GLP for profitable redemptions. Attack tx verified on-chain; all funds returned, $5M white-hat bounty.
- [Rhea Finance $18.4M slippage-check flaw](https://manyaitool.com/products/rhea-finance) - [md](https://manyaitool.com/products/rhea-finance/index.md): NEAR's top DeFi. Early labeled oracle manipulation, the real cause was a Burrowland margin slippage-check that summed per-hop min-outputs across a crafted route while settling actuals with no re-check. Loss revised $7.6M→$18.4M; ~$11.2M returned/frozen.
- [Aperture Finance $3.67M arbitrary call](https://manyaitool.com/products/aperture-finance) - [md](https://manyaitool.com/products/aperture-finance/index.md): An arbitrary-call flaw in the V3/V4 executor: the custom-swap function (selector 0x1d33) left call target/calldata unvalidated, letting the attacker craft transferFrom via the victim's pre-existing approvals and drain 36.9 WBTC. Main tx verified; ~$2.4M to Tornado.
- [Foom Cash $2.3M zk-verifier flaw](https://manyaitool.com/products/foom-cash) - [md](https://manyaitool.com/products/foom-cash/index.md): zk-SNARK privacy protocol: a skipped Phase-2 trusted-setup randomization left Groth16 gamma==delta, collapsing the pairing check to 1=1 so forged proofs passed without a witness. ~$2.26M drained across ETH+Base; ~$1.84M recovered by white hats.
- [Venus user $13.5M phishing blind-sign](https://manyaitool.com/products/venus-user) - [md](https://manyaitool.com/products/venus-user/index.md): A power user was phished via a fake Zoom client and a tampered wallet extension, blind-signing an updateDelegate that handed account-delegate rights to the attacker — ~$13.5M drained. The contract held; the signature didn't. Governance force-liquidated; funds fully recovered in 12h.
- [Aztec deprecated bridge $2.16M forged proof](https://manyaitool.com/products/aztec-deprecated-bridge) - [md](https://manyaitool.com/products/aztec-deprecated-bridge/index.md): A deprecated, immutable, abandoned RollupProcessor bridge: its escapeHatch had no access control and proofs weren't bound to fund ownership, so a forged proof drained ~1,158 ETH + 150k DAI in one tx. Tx and the now-empty victim contract verified on-chain.
- [Base fake-stablecoin scan: 70 fake PYUSD](https://manyaitool.com/products/base-fake-stablecoin-scan-70-fake-pyusd) - [md](https://manyaitool.com/products/base-fake-stablecoin-scan-70-fake-pyusd/index.md): Our in-house scanner flagged 70 fake stablecoins on Base impersonating PYUSD/FDUSD in a single pass: most with fake decimals (18 vs real PYUSD's 6) and very few holders — phishing-scam bait. All catalogued for lookup. Original first-party data.
- [Twyne v1 leveraged-lending audit](https://manyaitool.com/products/twyne-v1-leveraged-lending-audit) - [md](https://manyaitool.com/products/twyne-v1-leveraged-lending-audit/index.md): Full audit of a leveraged-lending protocol on Euler EVC/EVK: manual review of 11 contracts + Slither + Foundry fuzz, adversarially verifying and refuting 6 potential attack surfaces. Report includes a "ruled-out attacks" section.
- [Silo V3 isolated-lending audit](https://manyaitool.com/products/silo-v3-isolated-lending-audit) - [md](https://manyaitool.com/products/silo-v3-isolated-lending-audit/index.md): Manual + adversarial verification of the core silo-core: 0 highs, 7 candidate attack surfaces ruled out one by one, report public and verifiable.
- [ThunderLoan flash-loan audit (First Flight)](https://manyaitool.com/products/thunderloan-flash-loan-audit) - [md](https://manyaitool.com/products/thunderloan-flash-loan-audit/index.md): Audited the CodeHawks ThunderLoan flash-loan protocol; 3 Highs all PoC-proven: deposit() corrupts the exchange rate (redeem more than deposited, draining LPs), an upgrade storage-slot collision silently rewrites the fee, and a manipulable spot oracle enables zero-fee flash loans.
- [BriVault betting-vault audit (First Flight)](https://manyaitool.com/products/brivault-betting-vault-audit) - [md](https://manyaitool.com/products/brivault-betting-vault-audit/index.md): Audited the CodeHawks BriVault ERC4626 betting vault; 2 Criticals + 1 Medium all PoC-proven: a post-join re-deposit drains the entire prize pool (honest winner gets 0), overwriting accounting permanently locks a user's first deposit, and balanceOf-based pricing dilutes shares.
- [Multisig + timelock audit (First Flight)](https://manyaitool.com/products/multisig-timelock-audit) - [md](https://manyaitool.com/products/multisig-timelock-audit/index.md): Audited a CodeHawks 3-of-N multisig wallet; 1 High proven by PoC: revoking a signer never clears their confirmations on pending txs — these ghost votes stay in the quorum, so a single remaining signer can execute a 3-of-N transaction and drain the wallet.
- [Order-book DEX audit (First Flight)](https://manyaitool.com/products/order-book-dex-audit) - [md](https://manyaitool.com/products/order-book-dex-audit/index.md): Audited a CodeHawks order-book DEX; 1 High proven by PoC: buyOrder has no slippage bound, so a seller front-runs amendSellOrder to inflate price/shrink amount and drain the buyer's infinite USDC approval (900k USDC for 1 satoshi). Plus 1 Low; 2 issues adversarially excluded.
- [PuppyRaffle audit (First Flight)](https://manyaitool.com/products/puppyraffle-audit) - [md](https://manyaitool.com/products/puppyraffle-audit/index.md): Audited the classic CodeHawks PuppyRaffle; 2 Criticals + 3 Highs all PoC-proven: refund() reentrancy drains the contract (1 ETH in, 5 ETH out), predictable RNG, a uint64 fee overflow locking 20 ETH, a force-send DoS, and an O(n²) gas DoS on entry.
- [JuCoin $511M reserve debunk](https://manyaitool.com/products/jucoin) - [md](https://manyaitool.com/products/jucoin/index.md): On-chain data exposed their PoR: the "USDC reserve" was a self-deployed, mintable shitcoin with only 14 holders chain-wide. Done in minutes, at zero cost.
