“Everything is connected” but values differ
Check: Check whether the observations refer to the same chain, entity and block.
Next action: Keep separate records for page, RPC and indexer; do not merge them into one success flag.
Web3: stable exits for wallets, nodes and data collection
Configure the right proxy route for wallet activity, RPC access, explorers and on-chain data collection.
Build a request map before buying connectivity
For a page that loads but shows no data, identify who retrieves the missing value: the browser, wallet extension, application backend or a scheduled worker. One successful browser request does not show where the other clients send traffic.
Use the guides below to choose the right evidence. RPC checks need a chain and block; indexer checks need a deployment and indexed context. Community access has a separate eligibility boundary. Proxy302 provides proxy configuration options, not RPC nodes or wallet permissions.
Decide whether routing is the problem
Scroll horizontally with the arrow keys to read all content.
| Criterion | What to check | Next action |
|---|---|---|
| Wallet interface | Page loading, provider presence and account access separately | Use the wallet workflow; stop before permission prompts. |
| RPC or development client | Expected chain, response envelope and block identity | Try the bounded read-only example before any remote test. |
| Indexer / research feed | Deployment, entity, block and capture time | Repair data context or wait for indexing before rerouting. |
| Public reading | Exact URL, client, time and allowed comparison route | Compare only the failing client when site policy permits. |
When the direct route works and you have no regional or routing requirement, a proxy adds another component to diagnose.
Run a bounded diagnosis
Name the failed observation
Write one concrete symptom, such as “pool data stays at block 100 while the reference head is 105.” Keep it separate from “the page will not load.”
Identify the client and endpoint
Record the application component, endpoint host and protocol without API keys. Do not assume extension traffic follows browser-page proxy settings.
Define an unchanged comparison
Keep chain, contract or pool, block selection, request body and client version fixed. Compare direct versus an authorized alternate route only when transport is the suspected fault.
Read the result at the right layer
HTTP success can contain a JSON-RPC error or GraphQL errors. A syntactically valid response can still belong to another chain, deployment or block.
Evidence to keep
A useful incident record contains: symptom; request owner; redacted endpoint; method or query name; expected chain and entity; block number/hash where relevant; capture time; HTTP status; protocol error code; and the action taken. Never attach private keys, seed phrases, session tokens or full credential-bearing URLs.
Example triage: a page returns 200, the RPC says chain 0x1, and an indexer is behind the required block. The page route is reachable; the indexer has not yet supplied the required data. This paper example supplies no evidence about a live provider or regional exit.
Interpret a failure
Rate or access restriction
Check: Check the provider’s plan, permissions and documented retry guidance.
Next action: Reduce load or resolve authorization with the provider.
Stop when: Do not rotate exits to bypass the restriction.
Choose the next step
Use datacenter configuration for an authorized developer client only if the destination accepts that path. Residential research settings may be relevant to permitted public-page comparisons; static ISP settings can preserve a chosen browser exit. None changes gas, on-chain identity, voting power or provider quotas.
For local development and already-working direct reads, keep the simpler direct path. Choose a guide below to establish the missing evidence first.
