NFTMarketplace with Gasless Minting 1. An NFT marketplace is a digital platform for buying and selling NFTs. These platforms allow people to store and display their NFTs plus sell them to others for cryptocurrency or money. Some NFT marketplaces also allow users to mint their NFTs on the platform itself. 2. The platform allows you to list NFTs without paying any gas fees. This is achieved by pushing the blockchain transaction forward to when someone purchases the token. But, when listing an NFT on OpenSea, the seller's MetaMask – or any other wallet – will trigger

Develop an ERC721 Smart contract and store all whitelisted wallet address in Smart contract rather verify if wallet address is whitelisted using Merkle tree on Smart contract
This platform needs to enable users to join and participate in tournaments. The engineer will need to have knowledge in Solidity and Hardhat in order to implement the following flow: - User joins a web interface - User sees a list of active tournaments - User joins a tournament - User waits in the lobby
Write a smart contract that supports agreements between two users to sell a tangible item in exchange for ETH or any ERC-20 token. In case of disputes, the role of an arbitrator to resolve the dispute is to be included
Vault shares can be inflated by donating ERC20 token to the vault.
Non-fungible tokens can bundle as a pack, which allows them to be sold all at once as a group. NFT packs use templates to represent the physical trading card packaging in a retail store.
The defining idea of Uniswap v3 is concentrated liquidity: liquidity that is allocated within a custom price range. In earlier versions, liquidity was distributed uniformly along the price curve between 0 and infinity.
Uniswap contracts and its testcases
Open source forkable Ethereum dev stack
A whitelist address smart contract is used to restrict access to certain functionalities or resources within a decentralized application (DApp) or blockchain network. It allows the contract owner to specify a list of addresses that are allowed to interact with the contract, while denying access to any other addresses.
ERC-4907, which allows NFT holders to allow others to use their NFT for a specified period of time. After this period expires, users will no longer be able to access NFT.

Uniswap's oracles are now far easier and cheaper to integrate. V3 oracles are capable of providing time-weighted average prices (TWAPs) on demand for any period.the gas cost of v3 swaps on Ethereum mainnet is slightly cheaper than v2. Transactions made on the Optimism deployment will likely be significantly cheaper!
As of 0.8.24 solc does not grant access to a storage-type specifier to be able to easily define transient storage data structures. This library is meant to be a collection of various transient storage helpers and data structures.

Aave is a decentralized non-custodial liquidity protocol where users can participate as depositors or borrowers. Depositors provide liquidity to the market to earn a passive income, while borrowers are able to borrow in an overcollateralized (perpetually) or undercollateralized (one-block liquidity) fashion.
