Practical Example of How to Integrate ENS into Your dApp
summary
Concrete steps to add ENS name resolution and content hosting: use ethers/web3 or ensjs to call the registry and public resolver, set up reverse lookup properly with a bi-directional check, and publish site blobs as a contenthash on IPFS (upload via Temporal or a CI like Cyclic). ENS already supports 100+ coin types for multi-coin addresses. Notes on costs: mainnet registration and IPFS contenthash require high gas (tens to hundreds of dollars). Prototype L2 approach returns a gateway URL from the resolver so reads verify L2 proofs instead of forcing all writes on L1.
