I will blockchain development and dapp solutions

Smart contract projects span diverse domains. Token development uses ERC-20 for fungible tokens and ERC-721/1155 for NFTs, built with Solidity, OpenZeppelin, and Hardhat/Truffle, alongside tokenomics, vesting, and airdrop scripts. DAOs enable decentralized governance through proposals and voting using Governor contracts, Compound models, and tools like Snapshot, Aragon, and Tally. DeFi projects (e.g., lending, DEXs, yield farming) rely on liquidity pools, staking, Chainlink oracles, and governancebuilt with Solidity, Chainlink, and Ethers.js. Crypto wallets manage keys, sign transactions, and integrate with dApps via Web3Modal, WalletConnect, and smart wallet contracts. Exchanges can be DEXs (using AMMs, router/factory contracts, React + Ethers.js) or CEXs (Node.js + DB + custody contracts). L1 blockchains use Substrate or Cosmos SDK; L2s like rollups need cryptography and gas optimization, with Cairo and zkSNARKs for zkEVMs. Key tools include Solidity, Foundry, The Graph, IPFS, Infura, and Alchemy.
