SwapZap is a one-click "zap" DeFi tool: users hand over any ERC-20 token and the contract routes it through Uniswap V2 into a target asset in a single transaction. The team built it to make portfolio rebalancing effortless for retail users. During a routine pre-launch review, take a close look at how the swap call is constructed in the core contract — those raw router calls deserve scrutiny.

StreamPay is an on-chain payroll-streaming protocol. Employers fund a salary stream and employees withdraw their accrued pay continuously, second by second. The team rewrote the withdrawal hot path to shave gas off every payday transaction. Review the accounting logic and decide whether an employee can take home more than they earned.

Review the smart contract code for GameGold, a play-to-earn gaming token deployed on Ethereum. The token powers an in-game economy where players can upgrade items by burning tokens. The development team recently implemented a burnFrom function to allow the game contract to burn tokens on behalf of players who approve the operation. Players are reporting that their tokens are mysteriously disappearing. Investigate the token burning mechanism to identify any security issues.

Review the smart contracts for VestFlow, a token vesting protocol built on Superfluid streams. The protocol allows startups to vest tokens to investors over time using continuous money streams. Recently integrated with Superfluid's callback system for automated distributions. Examine how the protocol handles Superfluid callbacks and context data to ensure investor funds are protected.

Review the smart contracts for Obscura, a privacy-focused ERC20 payment token designed for anonymous transactions. The protocol implements non-standard approval mechanics to obscure spender identities on-chain. A major payment processor has integrated Obscura, and users are granting allowances for recurring payments. Examine the token transfer logic to ensure user funds are protected.

Review the smart contracts for GovCore, a decentralized governance protocol that recently launched on mainnet. The protocol allows token holders to vote on proposals that control a community treasury worth millions in ETH. The team implemented a custom ERC20 token with snapshot-based voting power. Auditors flagged potential issues with the token transfer mechanics. Examine how token balances and voting power are tracked to ensure the governance system cannot be manipulated.

Review the smart contracts for LuckyDraw, a decentralized lottery protocol on Ethereum. The platform allows users to purchase tickets for weekly prize pools, with winners selected on-chain for full transparency. After several rounds, the community noticed that the same wallet keeps winning despite low ticket holdings. Investigate the winner selection mechanism to ensure fair randomness.

Review the smart contracts for ArtBazaar, an NFT marketplace that allows digital artists to mint and list their artwork in a single seamless transaction. The platform recently integrated a new minting flow to improve user experience. The engineering team wants a security review of the mint-and-list functionality before the mainnet launch. Pay close attention to how state changes interact with external calls.

MetaLands is a virtual world platform where users can buy, sell, and trade digital land parcels as ERC721 NFTs. Each parcel has unique coordinates and properties that determine its value. The platform has seen massive growth with prime locations selling for significant amounts. Review the smart contract implementation to ensure the land trading mechanisms are secure.

Review the smart contracts for DonateChain, a decentralized charity platform built on Ethereum. The platform uses ERC677 tokens to enable seamless donations to verified beneficiary contracts. When donors transfer tokens, the platform automatically notifies recipient contracts via a callback mechanism. Examine how token transfers interact with external contracts to ensure donation security.

Review the smart contracts for VoteCore, a decentralized governance platform allowing token holders to create and vote on proposals. The protocol recently launched on mainnet and manages a treasury worth millions. The team implemented duplicate proposal detection using metadata hashing. Examine how proposals are identified and stored to ensure the governance mechanism cannot be manipulated.

YieldMax is a DeFi yield aggregator that optimizes returns by depositing user funds into Curve Finance LP pools. The protocol calculates vault share prices using Curve's virtual price oracle. A security audit has been requested before the mainnet launch. Review the vault deposit mechanism and oracle integration to ensure the pricing calculations cannot be exploited.

Review the smart contracts for DollarVault, a decentralized stablecoin lending protocol that allows users to deposit collateral and take instant loans. The protocol recently added support for ERC-777 tokens to improve user experience. The development team has requested a security audit before the mainnet launch. Examine how the borrowing mechanism handles token transfers and state updates.

Review the smart contracts for CollatNFT, a decentralized lending platform that allows users to borrow against their tokenized NFT collateral. The platform integrates with Balancer pools to determine fair market pricing for collateral valuation during loan issuance. The protocol recently added support for ERC777-compatible tokens. Examine how the price oracle fetches rates and ensure the collateral valuation mechanism is secure against manipulation.

Review the smart contracts for LendFi, a DeFi lending protocol that integrates with Balancer pools to offer flash loans. The protocol fetches token balances from the Balancer Vault to calculate collateral ratios and maximum loan amounts. The team recently launched on mainnet after a quick audit. Examine how the protocol interacts with external contracts and handles balance calculations during loan operations.
