What the web3 is going on?!
summary
Clear claims and working tools: Ethereum is the chosen platform, proof of stake cuts energy use by about 99.6% after the merge, wallets and libraries used are rainbow kit and wagmi and demos run via Remix and MetaMask. Built a 20‑line Solidity club contract, deployed to mainnet (deployment cost ≈ $8) and attempted a join transaction (≈ $0.33) that initially failed with out‑of‑gas, while a separate donation transaction to Ukraine succeeds and shows expected block confirmations.
