Syntegrity Lead by Nirlin

Syntegrity is the only auditing firm offering both solo and team audits with flexible pricing and niche-specific experts. (If you are a lending platform, only an auditor expert in lending products will audit your product; we don't believe in generalized auditors, especially for larger scopes.)

Benefits:

Group 15

  1. Before manual audit each codebase is run through LightChaser Bot, cost for this is paid by Syntegrity and nothing is charged to end user. For 1 run light chaser costs $1000.
  2. Clients will get niche experts instead of generalized auditors.
  3. Founder lead solo and team audits on demand.
  4. Each auditor has a different level of skillset, so we mix and match to give the best possible combination at the best possible price.

📊 Contest Findings

Dopex Findings

High Severity

  1. The settle feature will be broken if attacker arbitrarily transfer collateral tokens to the PerpetualAtlanticVaultLP

Medium Severity

  1. Change of fundingDuration causes "time travel" of PerpetualAtlanticVault.nextFundingPaymentTimestamp()

  2. User can avoid paying high premium price by correctly timing his bond call

  3. Inaccurate swap amount calculation in ReLP leads to stuck tokens and lost liquidity

Axelar Findings

Medium Severity

  1. Interchain token transfer can be dossed due to flow limit

High Severity

  1. recipientsCounter should start from 1 in DonationVotingMerkleDistributionBaseStrategy

  2. Registry.sol generate clone Anchor.sol never work. Profile owner cannot use their Anchor wallet

Medium Severity

  1. The RFPSimpleStrategy._registerRecipient() does not work when the strategy was created using the useRegistryAnchor=true causing that nobody can register to the pool

  2. CREATE3 is not available in the zkSync Era.

  3. Anchor contract is unable to receive NFTs of any kind

Ondo Finance Findings

Medium Severity

  1. All bridged funds will be lost for the users using the account abstraction wallet

ENS Findings

Medium Severity

  1. Some tokens enable the direct draining of all approved ERC20Votes tokens

#Y2k Finance Findings

High Severity

  1. Funds can be stolen because of incorrect update to ownerToRollOverQueueIndex for existing rollovers

Medium Severity

  1. ControllerPeggedAssetV2: outdated price may be used which can lead to wrong depeg events

  2. ControllerPeggedAssetV2: triggerEndEpoch function can be called even if epoch is null epoch leading to loss of funds

  3. VaultFactoryV2#changeTreasury misconfigures the vault

Footium Findings

Medium Severity

  1. Users might lose funds as claimERC20Prize() doesn't revert for no-revert-on-transfer tokens

IronSide Findings

Medium Severity

  1. Vulnerability not specified

  2. PriceOracle will use the wrong price if the Chainlink registry returns price outside min/max range

  3. getPriceFromChainlink() doesn't check If Arbitrum sequencer is down in Chainlink feeds

USSD Findings

High Severity

  1. Price calculation susceptible to flashloan exploits

  2. Not using slippage parameter or deadline while swapping on UniswapV3

  3. Lack of access control for mintRebalancer() and burnRebalancer()

Medium Severity

  1. Calls to Oracles don't check for stale prices

  2. Risk of Incorrect Asset Pricing by StableOracle in Case of Underlying Aggregator Reaching minAnswer

  3. Lack of Redeem Feature

Index Coop Findings

Medium Severity

  1. No validation to ensure the arbitrum sequencer is down

  2. Chainlink price feed is deprecated, not sufficiently validated and can return stale prices

Unstoppable Findings

High Severity

  1. Vault: _update_debt does not accrue interest

  2. Adversary manipulate the middle path when calling execute_dca_order, resulting user loss, benefiting the attacker

  3. Interested calculated is amplified by multiple of 1000 in _debt_interest_since_last_update

Hubble Exchange Findings

Medium Severity

  1. User will be forced liquidated

  2. No minAnswer/maxAnswer Circuit Breaker Checks while Querying Prices in Oracle.sol

  3. Chainlink.latestRoundData() may return stale results

Personal Projects and Contributions

The Proof of Concept (POC) for the recent thirdweb exploit: A simplified ERC20 version utilizing ERC2771 context and OpenZeppelin's Multicall, demonstrating the potential for an attacker to transfer anyone's tokens among other exploits. Participated in multiple contests and consistently ranked in the top 5, showcasing a strong understanding and skill set in smart contract security. Repo Link
