Summary: Looking ahead to 2025, making sure Web3 APIs are “highly available” means getting ready for chain upgrades like Dencun and Pectra, figuring out those quirky L2 sequencer issues, understanding the limits of different providers, and handling real-time streaming on a large scale. This guide dives into what really matters in everyday situations--like using method-aware load balancing, implementing reorg-safe caching, ensuring reliable transaction submission, and having actionable observability.

Designing High-Availability Web3 API Clusters for Mission-Critical Apps

Decision-makers are increasingly throwing the same question our way: how do we make sure that wallets, exchanges, AI agents, and enterprise apps using Web3 APIs are reliable without blowing our budget? By late 2025, it's clear that the answer isn’t just to “add more nodes.” What we really need is an adaptable architecture that can handle protocol changes (like Ethereum’s Dencun and Pectra), the quirks of L2 behavior, the variations among different providers, and the needs of streaming workloads.

Here’s a great overview of everything we've launched and handled across various chains and clouds this year.

1) Why “HA” is different in 2025

• The recent Dencun upgrade for Ethereum introduced blob transactions (EIP‑4844) into the ecosystem. These blobs are here for a brief 18 days on consensus clients, so it's important to get your data access and indexing sorted out for this fleeting data availability. Plus, keep an eye out for the new fields like baseFeePerBlobGas in the fee history. Dencun officially launched on March 13, 2024, at 13:55 UTC. You can find more details on ethereum.org.
• The Pectra hard fork dropped on May 7, 2025, and it brought some exciting updates! It introduced EIP‑7702, which means we now have programmable EOAs, and EIP‑7691 boosted blob throughput to target 6 blobs, with a max of 9 blobs per block. If your API layer’s checking out transactions, receipts, or fee markets, just a heads-up--there are going to be some distribution changes and a quicker L2 batch pace ahead. Check it out for more details over at CoinDesk!
• L2s are definitely reliable, but they’re not without their quirks. Take platforms like OP Stack and Arbitrum, for example--they provide a “force inclusion” feature if their sequencers hit a snag. Just a heads-up: this process can take about 12-24 hours, so it might shake up the way you handle your RTO/RPO. It's smart to think ahead for those times when the service might be a bit shaky, not just during the outright failures. (docs.optimism.io)
• Non‑EVM chains have their own set of rules when things go a bit haywire. Take Solana, for example; they hit a 5-hour outage on February 6, 2024. Because of this unpredictability, it makes sense to set up cross‑RPC redundancy and implement commit‑level reads (you know, the ones that feel “finalized”) for those state reads to keep everything running smoothly. (theblock.co)

2) Set explicit SLOs (and negotiate SLAs)

• Set SLOs for each method class:
  • For reads: we should monitor the p95 latency and success rates for methods such as eth_call, eth_getLogs, getProgramAccounts, and similar ones.
  • For writes: keep tabs on whether submissions are successful within N blocks, assess how robust the resubmission process is against duplicates, and track the time it takes to receive final acknowledgment.
• Provider SLAs: Here’s the Scoop
  • Chainstack really stands out here. They openly promise 99.9% uptime every quarter and even offer credits if they fall short. Plus, they've got their incident windows and response SLAs laid out in a way that's easy to understand. This could definitely serve as a solid benchmark for your needs. (chainstack.com)
  • On the flip side, Infura’s status history reveals that the user experience can change based on the access method (like HTTPS JSON-RPC compared to WS). So, it’s wise to keep a close watch on the uptime specific to your setup, instead of just trusting their marketing materials. (status.infura.io)
  • A lot of providers will brag about achieving 99.99%+ uptime and managing billions of requests daily--just make sure you're checking this against your own telemetry data instead of taking their claims at face value. (chainstack.com)

Tip: Don't forget to link those credits to actual business impact, like lost trade opportunities, instead of just focusing on the downtime minutes.

3) Method‑aware, multi‑provider routing

Static round-robin is starting to feel a bit outdated. Let’s shake things up and route with a blend of method, chain, and payload weight instead!

• Split traffic by method class:
  • When you're dealing with heavy scans like eth_getLogs and debug/trace, it’s a good idea to choose providers that offer wide ranges and high result limits. If you're running live reads with eth_call or eth_getBalance, you’ll want to stick to low-latency pools. For your write paths, look for providers that have a reputation for solid TX propagation. Providers like Alchemy, Chainstack, TheRPC, and Dwellir clearly outline their eth_getLogs limits, so keep those in mind while setting up your router. (alchemy.com)
• Paginate eth_getLogs to dodge those annoying limits. Try sticking to block ranges that won’t go overboard--aim for around 2k-10k, depending on the chain and your strategy. And don’t forget to keep an eye on the result size limits--they're typically about 10k logs or around 150MB. Make sure your router can handle some smart auto-chunking and parallel processing. (alchemy.com)
• Opt for eth_getBlockReceipts when you're working with indexers whenever you can. It’s way more efficient--just one call per block instead of juggling multiple receipts. Most of the major providers and clients are on board with this now, so only go back to the old method if you absolutely have to. (quicknode.com)
• For subscriptions:
  • Go ahead and use newHeads/logs via WebSocket with sticky sessions. Just keep in mind that a lot of those "pending tx" streams only show what's in the provider's own mempool (yes, we're looking at you, Alchemy). So, it’s a good idea to manage your expectations and handle deduplication as needed. (alchemy.com)

Concrete LB patterns

• Consider putting Envoy or HAProxy in front of your provider pools:
  • Make sure to set up health checks tailored to your method--think along the lines of checking for an HTTP 200 status and validating some JSON-RPC results.
  • Keep an eye out for those annoying 5xx errors and timeouts by using outlier detection and ejection. A conservative max_ejection_percent can really save you from taking down the whole pool. You can dive deeper into this topic at (envoyproxy.io).
  • Don’t forget to implement a retry policy with per-try timeouts--somewhere between 500 and 800ms works pretty well. Also, when you start noticing those stubborn tail latency spikes, consider hedged requests by setting hedge_on_per_try_timeout to true. For more info, check out (kgateway.dev).
• WebSockets:
  • Great news if you're using ALB! It supports WebSockets right out of the box. Just make sure to adjust your idle timeouts for those long-lasting subscriptions. If you're dealing with TCP pass-through or QUIC, take a look at NLB--it lets you configure idle timeouts and has options for QUIC passthrough too. And for those using Cloudflare, they’ve got your back with proxied WebSockets and have recently increased the WS message limits for Workers. Check out more details here: (docs.aws.amazon.com).

4) Reorg‑safe caching and consistency

• Cache those immutable results by using the block hash. When you're working with tags like latest, safe, and finalized, it's a good idea to choose your Time-to-Live (TTL) based on how much risk you're comfortable with:
  • latest: Keep it short with a quick TTL and stay on top of things by being reorg-aware and ready to invalidate when necessary.
  • safe/finalized: Here’s where you can go for a heavier caching approach (finality is usually about two epochs, which is around 12-15 minutes these days). And don’t forget to toss in a “consistency tier” header for your callers. Check out the details on ethereum.org.
• For estimating fees, make sure you’re using eth_feeHistory (feel free to include some percentiles if that helps) instead of sticking with static tips. And don’t overlook those blob fee fields after Dencun/Pectra. For more info, swing by quicknode.com.

5) Transaction submission that doesn’t lose money

• Idempotent Resubmission: When you're resending the same signed transaction hash to different providers, just double-check that it’s not already chilling in the mempool. And be prepared to tackle those pesky “already known/underpriced” (-32000 variants) errors like a pro. It’s super important to understand those JSON-RPC error codes so you can figure out whether to give it another shot or just let it go. For more info, take a look here.
• Gas Policy:
  • When it comes to setting your maxPriorityFeePerGas, make sure to pull those percentiles from eth_feeHistory instead of just guessing them. It’s worth checking out the provider hints for max tip edges as well. You can grab more details here.
• Private Orderflow for Sensitive Transactions:
  • If you’re using Flashbots Protect RPC, you're in for a treat! This is perfect for keeping your transactions hidden from the public mempool and making sure you’re throwing in some non-zero tips. They’ve made some recent updates to their rate limits and deprecations, so it's a good idea to switch to the "fast" multiplexing mode when you really need that speed. Check out how to set it all up here.
• Keep an Eye on Mempool Placement:
  • For those of you with self-hosted clients, make sure to enable txpool_content/status (for Geth, Nethermind, or Reth). This will let you check for any nonce gaps and assess how effective your replacement policy is. You can find all the info here.

Example: provider‑aware send strategy (pseudocode)

send(rawTx):
  feePolicy = feeHistoryPolicy(chain)
  signed = applyFeePolicy(rawTx, feePolicy)

  for attempt in [0..N]:
    for provider in writePool.prioritized():
      res = provider.eth_sendRawTransaction(signed)
      if res.ok: return res.hash
      if res.error in [ALREADY_KNOWN, REPLACEMENT_UNDERPRICED]: continue
      if res.error in [RATE_LIMIT, GATEWAY_TIMEOUT]: backoff.exponentialJitter()
    maybeSwitchToPrivateRPCIfSensitive()
  throw FatalSubmissionError

6) L2 specifics you must design for

• OP Stack Forced-Tx Window (Sequencer Downtime): Even if the sequencer is down, you can still make deposits through L1. Just remember, the timing can change depending on how long the sequencer has been offline: under 30 minutes, 30 minutes to 12 hours, and over 12 hours. Each of these situations will require you to tweak your app a bit, like adding UX banners and adjusting the settlement modes. And don’t forget to implement toggles to restrict some functionalities when you're in “forced-inclusion only” mode. For more info, check it out here.
• Arbitrum Delayed Inbox: Hey folks, just a quick heads-up! Users can go around the sequencer after roughly 24 hours. It's smart to include a "delayed path" option in your admin tools. Also, be sure to jot down any trade-offs in cost and latency that could pop up. For more details, check out this link.
• Post‑Pectra blobspace: With the increased throughput from EIP‑7691, L2 batchers are going to have to adjust their posting frequency and the fees they set. It’s a good idea to warm up your caches and boost the subscription fan-out capacity on those upgrade days. For more details, check out this site.

7) Solana and non‑EVM: different weight classes, different limits

• Remember that there are some method-specific limits when it comes to Solana. For instance, when you’re using getProgramAccounts with strict filters and the dataSlice feature, the recommended requests per second (RPS) is quite low. To get accurate balances and positions that matter to your finances, it’s a good idea to stick to the “finalized” commitment. You can find all the details here.
• Get ready for those occasional but impactful outages:
  • Think about using multi-RPC rotation and maybe drop your commitment from finalized to confirmed if you’re seeing some lag due to leader changes. Also, keep an eye on backpressure when getProgramAccounts gets stuck. The February 2024 outage on Solana really drives home the need for fallback plans. You can check out more details here.

8) Security, networking, and zero‑trust perimeters

• Keep your raw client RPC ports under wraps--it's much safer to handle TLS at a gateway. And don’t forget to enforce JWT/API keys and mTLS between your service tiers. If you’re using an ALB, you can actually offload the JWT verification right to the balancer for service-to-service authentication. Take a look at this for more info: (aws.amazon.com).
• For long-lasting connections, such as WebSockets on Cloudflare or AWS, make sure you get those idle timeouts and WebSocket headers just the way you need them. If you overlook this tuning, you might find yourself facing those pesky ghost disconnects when things get busy. Want to dive deeper? Check it out here: (developers.cloudflare.com).
• Don't forget, configuration risks are just as important as the code you're writing. There have been some eye-opening instances where misconfigurations in ALB/WAF allowed authentication bypasses to sneak in--so really, it's a good idea to treat your infrastructure like you would your code. Make sure to throw in some policy tests to keep everything running smoothly. Check out this interesting article for more insight: (wired.com).

9) Observability you can act on (OpenTelemetry)

Instrument the API Gateway with OpenTelemetry’s JSON-RPC Semantic Conventions

Setting Up Your API Gateway with OpenTelemetry’s JSON-RPC Semantic Conventions

Alright, let’s get into it! We’re going to set up your API gateway using OpenTelemetry’s JSON-RPC semantic conventions. This is going to help you keep tabs on your API calls and trace them like a pro. Ready to roll? Let’s do this!

Step 1: Install OpenTelemetry

First things first, you’ve gotta install the required packages. If you’re working with Node.js, here's how you can do it:

npm install @opentelemetry/api @opentelemetry/sdk-node @opentelemetry/instrumentation

Step 2: Initialize OpenTelemetry

Next up, we need to get OpenTelemetry all set up. Here’s a quick example of how to do that:

const { NodeSDK } = require('@opentelemetry/sdk-node');

const sdk = new NodeSDK({
  // Specify your options here
});

sdk.start()
  .then(() => console.log('OpenTelemetry is running!'))
  .catch(console.error);

Step 3: Define Your Semantic Conventions

Now that everything’s set up, let’s define some semantic conventions to track our API calls. This is where the magic happens! You’ll want to follow the JSON-RPC standards and set up your traces accordingly.

For example, you can define traces like this:

const { trace } = require('@opentelemetry/api');

const tracer = trace.getTracer('your-service-name');

const span = tracer.startSpan('myApiCall');
// Perform your API call here
span.end();

Step 4: Monitor Your API Calls

After you’ve defined your conventions, you’ll want to start monitoring those API calls. Consider integrating a visualization tool or dashboard to see your traces in action. Tools like Jaeger or Zipkin can be super helpful for this!

Example Tools

• Jaeger: Great for distributed tracing.
• Zipkin: Another solid option for monitoring.

Step 5: Review and Optimize

Once everything’s up and running, take a step back and review your setup. Look for any bottlenecks or areas that could use a bit of optimization. Remember, good monitoring helps you catch issues before they become big problems!

Conclusion

And there you have it! You’re all set to track and monitor your API calls using OpenTelemetry’s JSON-RPC semantic conventions. Happy coding, and may your API calls be smooth and efficient!

For more detailed information, check out the OpenTelemetry documentation.

Step 1: Setting Up OpenTelemetry

Alright, let’s kick things off by getting OpenTelemetry set up. If you haven’t done it yet, go ahead and grab the OpenTelemetry SDK for the programming language you’re using. You can find it hanging out in the official OpenTelemetry GitHub repository.

Quick Setup for Node.js:

Setting up Node.js on your machine is super straightforward! Let’s break it down step by step.

Step 1: Download Node.js

Head over to the Node.js official website. You’ll see two versions available:

• LTS (Long Term Support): This one is recommended for most users because it’s stable and tested.
• Current: This has the latest features but might have some bugs.

Choose the one that suits your needs and download it for your operating system.

Step 2: Install Node.js

Once the download is complete, open the installer and follow the prompts. Just keep clicking “Next” until it’s all done! If you’re on a Mac, you might need to drag and drop the Node.js icon into your Applications folder.

Step 3: Verify the Installation

To make sure everything's working fine, open up your terminal or command prompt and type:

node -v

This command will show you the version of Node.js you just installed. If you see a version number, congratulations! You’ve successfully installed Node.js.

Step 4: Install npm

When you installed Node.js, npm (Node Package Manager) came along for the ride. You can check if it’s installed by typing:

npm -v

If you see a version number, you’re all set!

Step 5: Create Your First Project

Now, let’s create a simple project to test things out.

1. Create a new directory for your project:

   mkdir my-first-node-project
   cd my-first-node-project

2. Initialize a new Node.js project:

   npm init -y

   This command will create a package.json file with default settings.

3. Create an index.js file:

   touch index.js

4. Open index.js in your favorite text editor and add this code:

   console.log("Hello, Node.js!");

5. Run your project:

   node index.js

   You should see "Hello, Node.js!" printed in your terminal.

Additional Resources

• Node.js Documentation
• npm Documentation

And that’s it! You’re all set up and ready to dive into the world of Node.js! Happy coding!

npm install @opentelemetry/api @opentelemetry/sdk-node @opentelemetry/exporter-console

Step 2: Add the JSON-RPC Semantic Conventions

Once you've got OpenTelemetry up and running, it’s time to dive into the JSON-RPC semantic conventions. This step involves setting up trace contexts and attributes that match up with the JSON-RPC specs.

Here's a simple example for your API gateway:

const { trace } = require('@opentelemetry/api');

const tracer = trace.getTracer('api-gateway');

// Define JSON-RPC attributes
const jsonRpcAttributes = {
  'jsonrpc': '2.0',
  'method': 'exampleMethod',
  'params': { key: 'value' },
};

// Start a new span for the JSON-RPC request
const span = tracer.startSpan('json-rpc-request', {
  attributes: jsonRpcAttributes,
});

// Perform your API logic here...

// End the span when done
span.end();

Step 3: Use Middleware for Tracking

If you're diving into an Express app, using middleware can really simplify things for you. You can set up a middleware function that will automatically log every JSON-RPC request that comes in. Check out this example:

app.use((req, res, next) => {
  const span = tracer.startSpan('json-rpc-request', {
    attributes: { jsonrpc: '2.0', method: req.method },
  });

  res.on('finish', () => {
    span.setStatus({ code: res.statusCode < 400 ? 1 : 0 });
    span.end();
  });

  next();
});

Step 4: Exporting Your Traces

Make sure you set up a trace exporter! If you're in debugging mode, the console exporter is handy, but for a more robust solution, you can go with something like Jaeger or Zipkin. Here’s a quick guide to get the console exporter up and running:

const { NodeSDK } = require('@opentelemetry/sdk-node');
const { ConsoleSpanExporter } = require('@opentelemetry/exporter-console');

// Set up the SDK with the console exporter
const sdk = new NodeSDK({
  traceExporter: new ConsoleSpanExporter(),
});

// Start the SDK
sdk.start();

Step 5: Review and Adjust

Once you’ve got everything up and running, keep an eye on your traces and logs to check if they match what you were expecting. If something feels off, don’t hesitate to tweak any attributes or spans to make them work better for you.

Taking the initiative to track your API calls can really help you understand performance better and make troubleshooting a lot easier. Best of luck with your implementation, and happy tracking!

• You’ll need to include a few key attributes: rpc.system=jsonrpc, rpc.method, rpc.jsonrpc.version, and if things go sideways, don’t forget about rpc.jsonrpc.error_code/message. This setup is super handy for keeping an eye on the 95th percentile for each method by provider, and it lets you set up alerts for different clusters of error codes (like -32005 for rate limits or -32603 for internal errors). For more details, check it out at (opentelemetry.opendocs.io).

Key Golden Signals to Expose:

1. Latency
   Watch out for how long it takes to process requests. If you start seeing some delays, that's a sign that something might be off.
2. Traffic
   Keep an eye on how many requests are rolling in. If you see a sudden jump, it could mean something cool is happening--like a new marketing campaign kicking off. But don’t ignore it; it might also point to a potential problem, such as a DDoS attack.
3. Errors
   Keep an eye on the error rates in your app. If you notice an increase in errors, it's crucial to get to the bottom of what’s causing them before they start impacting your users.
4. Saturation
   Keep an eye on how your resources are being used--things like CPU, memory, and disk I/O. If you notice these are running high, it could be a good time to consider either scaling up or fine-tuning your services.
5. Apdex Score
   The Apdex score is a handy way to gauge user satisfaction by analyzing how many requests meet those comfy response time benchmarks. If you find yourself with a low Apdex score, it could be a warning sign that there are some user experience hiccups going on.

By keeping an eye on these signals, you’ll be able to catch any potential issues before they become major headaches and make sure your system operates like a well-oiled machine!

• Read path: Check out the p95 latency, sorted by method, result size, and cache hit ratio, all based on the block tag (latest/safe/finalized).
• Write path: Dive into the inclusion time histogram (from submit to in-block), plus keep an eye on the replacement/bump rate and revert rate based on route (public vs private RPC).
• Streaming: Check out the WS subscription count for each shard, the reconnect rate, and how many duplicate events pop up during reorgs.

10) Reference architecture (battle‑tested)

• Global anycast DNS → Cloud CDN (this one's optional for static assets) → API Gateway (using Envoy/HAProxy) that comes with:
  • Method-aware routing tables for every chain, managing both HTTP and WS clusters.
  • Circuit breakers to cap off the maximum concurrent and pending requests, outlier detection, timeouts for each try, and hedging. (envoyproxy.io)
• Pools:
  • Read-pool A: This one’s all about low-latency providers.
  • Read-pool B: Built for those heavy-scan providers, and it can handle higher result limits.
  • Write-pool: Made up of 2-3 different providers, plus we’ve got a private orderflow RPC (Flashbots Protect) for those sensitive transactions. Check out more details here!
• Caching:
  • L1: This is our in-process response cache. It’s based on the method and parameters, and the coolest part? It’s totally immutable due to the block hash.
  • L2: Here, we have a Redis cluster that's smart with tag-aware TTL, which helps us tell apart the latest updates from the finalized ones.
• State and indexing:
  • The log indexer starts by calling eth_getBlockReceipts. If that doesn't do the trick, it switches gears and uses log-paged eth_getLogs, working with block windows ranging from 2k to 5k.
• WS:
  • We've got sticky sessions set up at the load balancer, along with auto-reconnect that includes resubscription. Plus, we’ll backfill from the last block you saw.
• Security:
  • We’re using JWT at the edge, whether it's through ALB or gateway, plus mTLS for our egress proxies. And don’t forget about those WAF rules to make sure that only the permitted methods are in play.
• Ops:
  • We’re sending OTel traces to a TSDB to whip up those awesome p95/p99 dashboards. Plus, we're rolling out SLO burn alerts for each method (you know, like keeping an eye on the “error budget” for eth_getLogs).

11) Practical “gotchas” we see weekly--and how to fix them

• "Looks like we’re caching the latest data a bit too aggressively, and users are running into some strange rollbacks."
  • Fix: How about we split our caches into latest, safe, and finalized data? By default, user reads should go to safe unless they really need those latest updates. (ethereum.org)
• “It looks like the pending transaction stream is lacking some activity from the mempool.”
  • Most providers tend to only stream their own mempool. To get a clearer view of what's happening, you might want to mix it up with different WS providers or combine newHeads with receipts. This way, you won’t have to depend only on pending transactions. (alchemy.com)
• “getLogs is timing out way too often.”
  • Let’s think about using provider-specific windowing and setting some result caps (like 2k blocks or 10k logs). Sharding by address or topics could be helpful, and we should definitely explore parallelizing with some backoff. (alchemy.com)
• “Gas prices usually jump on days when upgrades happen.”
  • It’s smart to look at eth_feeHistory percentiles and pay attention to blob fee signals after Dencun/Pectra. Plus, reducing cache TTLs during forks can really help avoid problems. (quicknode.com)
• “Our WebSocket connection drops every few minutes.”
  • First off, take a look at those idle timeouts--things like NLB, ALB, or Cloudflare can really mess with your connection. Also, don’t forget to enable keep-alives or pings on your client side. Lastly, double-check that stickiness is doing its job properly. You can find more info on this here.

12) Budgeting for reliability

• Spend where it pays:
  • Opting for one solid premium provider for your heavy-duty tasks, a low-latency option for read operations, and a private order flow RPC usually gets you more bang for your buck while minimizing risks, especially compared to an “all-in-one” setup.
  • Consider adjusting your indexers to focus on receipts-first pipelines; this small change can cut down log-scan calls by a whopping 60-80% during those hectic block times. (quicknode.com)
• Let the load balancer handle authentication and basic rate limits. For those method-specific limits, keep them in the gateway for a bit more accuracy.
• Make sure to set aside some headroom when forks are coming up. Just a heads up, the Dencun and Pectra days were pretty crazy, with some major spikes in blob activity and fee fluctuations. Check it out here: (galaxy.com)
