summary

Shows step-by-step how to go from a local counter app to a live deployment using Scaffold-ETH and Speedrun Ethereum: run yarn deploy-work arbitrum, change the scaffold config, deploy the frontend with cursor and publish to IPFS. Deploying the counter to Arbitrum costs a fraction of a cent to deploy but the presenter notes ~1000 txns cost ~$180; wallet interaction pays real money to increment. Covers building a DEX with constant-product xy=k*, liquidity providers earning fees, staking, token vendors, and commit-reveal vs VRF randomness and attacker patterns.
