An Ethereum website can distribute its frontend through IPFS without moving contract execution into the storage network. The browser still receives HTML, CSS, JavaScript, and assets. The application may then read blockchain state through an RPC endpoint and ask a wallet to authorize an action. Those are separate responsibilities, with separate failure modes and trust boundaries.
The practical benefit of separating them is clarity. You can identify a frontend release by its CID while independently documenting the chain, contracts, wallet behavior, and external services it expects. This guide focuses on that release architecture, not on writing a token contract or recommending a financial application. The IPFS Ethereum website overview provides a shorter starting point.
Draw the application before deploying it
Write down the frontend, wallet, RPC service, contract addresses, indexers, and any external data sources. Mark which pieces are included in the published folder and which are contacted at runtime. A site that loads from IPFS may still depend heavily on centralized services; the architecture should describe those dependencies honestly.
The Ethereum developer introduction to dApps distinguishes the user-facing frontend from the smart-contract application and notes that a frontend can be hosted on IPFS. Use that boundary as the starting point for your own diagram rather than treating decentralized as an all-or-nothing label.
For each component, record who controls it and what a failure looks like. A missing image, unavailable RPC endpoint, rejected wallet request, and reverted transaction should not all appear to the user as the same generic error.
Make the initial page useful without a wallet
Do not require a wallet connection just to read what an application does. Explain the purpose, supported network, relevant risks, and available read-only information before asking for authorization. A visitor should be able to understand the interface and leave without triggering a connection prompt.
Separate connection from signing. Connecting a wallet is not the same as authorizing a transaction, and the interface should not blur those actions. Use explicit labels that describe the next step rather than vague instructions to continue or verify.
Test the page with no wallet extension installed. Provide an informative state instead of an exception or a permanently spinning control. Also test a user declining the request. A refusal is an ordinary user choice, not an application failure to be punished with repeated prompts.
Lock down network and contract configuration
Maintain an explicit mapping between each supported chain and its approved contract addresses. Do not infer that a contract with the same name or an address copied from another network is the intended destination. Treat configuration changes as reviewable release changes.
Display the selected network and the important destination information near an action. Before preparing a transaction, confirm that the wallet's current network matches the application's expectations. Handle a network change while the page is open, rather than assuming the initial connection stays valid forever.
Keep development and production settings clearly separated. A test interface should not silently switch to mainnet because a missing environment variable falls back to a convenient default. Fail visibly when critical configuration is absent.
Choose a browser-safe delivery context
The origin under which the frontend runs affects browser storage, permissions, and interactions with external services. Test the intended custom domain or gateway origin, not just a local development URL. An application working under one hostname does not establish that wallet discovery, API access, and storage behave identically under another.
Prefer an intentionally isolated origin for an application interface. Avoid assuming that arbitrary sites served beneath the same public gateway hostname are independent origins merely because their CID paths differ. The IPFS dApp architecture guide explains why delivery context belongs in your security review.
Keep the set of supported public entry points small enough to test. Additional mirrors can be useful, but each should have a documented release identity and an intentional relationship to the canonical domain.
Keep secrets out of the release
Everything delivered to a browser must be treated as available to the visitor. Private RPC credentials, deployment keys, pinning tokens, and administrative secrets do not belong in the frontend bundle. A minified file is not encrypted, and a configuration variable does not become private because its name looks internal.
Some services offer browser-facing identifiers with origin restrictions or limited permissions. Review the actual service's security model instead of treating every API key as interchangeable. Document any runtime dependency and its limits so an operator knows what can fail after the files have been published.
Scan the production output, not only the source repository. Build tools can substitute values into JavaScript or generate files that expose more configuration than a developer expects.
Model the transaction journey clearly
A useful interface distinguishes preparation, wallet review, submission, and observed network outcome. Do not display success merely because a wallet returned control to the page. A transaction identifier can help track an action, but it should not be presented as proof that the intended state change is complete.
Keep the user's intended amount, destination, and action visible throughout the journey. Avoid replacing meaningful information with an animation while the user is making an authorization decision. If the application changes the transaction after an error, explain the change and request authorization for the new action.
Handle rejection, RPC unavailability, insufficient resources, and contract errors as distinct cases where possible. The interface should help the user understand what happened without pretending to diagnose every network condition with certainty.
Review approvals as their own action
When an application requests permission for a contract to use a token, make that permission understandable. Identify the spender and scope instead of presenting approval as a harmless login step. Do not hide a broad allowance request inside a generic setup button.
Choose the narrowest authorization that satisfies the actual workflow where the implementation supports it. Review how the application behaves when an approval already exists, when it is revoked, or when the contract configuration changes. Avoid assuming that a previously granted permission remains appropriate for every future release.
This is an interface-design responsibility, not a claim that frontend copy can eliminate contract risk. A clear page still needs reviewed application logic and accurate configuration.
Publish a versioned frontend release
Build the static output, inspect its files, and record the source revision alongside the root CID. Include the expected network and contract configuration in the release record. Verify that the files are retained before changing the public domain or naming pointer.
Keep a previous working frontend available for rollback, but review compatibility before restoring it. A historical interface may expect an older contract configuration or external API. Rolling back the page files does not roll back blockchain state.
Our first IPFS static-site release walkthrough covers the ordinary file and link checks. Apply those checks before testing transaction behavior, so hosting mistakes do not obscure application-level failures.
Test the uncomfortable paths
Test with an unavailable RPC service, a wrong network, a rejected wallet request, a disconnected wallet, and a page reload during a pending action. Use appropriate test environments rather than experimenting with real funds to discover basic interface errors.
Verify that retrying does not accidentally encourage duplicate actions. Preserve enough context to explain an uncertain outcome, and avoid telling users to repeat a transaction immediately when the application has simply lost contact with its observer.
Keep a release-specific test record
Record which release and environment passed each test. A test performed against a development build is not evidence that the exact published bundle contains the same configuration.
Conclusion: make each trust boundary visible
An Ethereum frontend on IPFS is most useful when the release identity, browser origin, runtime services, and authorization flow are all explicit. Keep read-only information accessible, separate wallet actions, review configuration, and test failure states before publication. Content-addressed hosting can give the frontend a clear version boundary. It does not replace contract review, secure wallet behavior, or a responsible plan for the services the interface still relies on.
