Infura vs Alchemy: Two Different Theories on What Developer Infrastructure Should Be

Most developers building on Ethereum don't run their own nodes. Running a full Ethereum node requires hundreds of gigabytes of storage, reliable uptime, constant syncing, and ongoing maintenance. For most use cases, it's not worth it — especially early in a project when you're moving fast and need reliable RPC access to read chain state and broadcast transactions.

Infura and Alchemy are the two dominant providers solving this problem. They run the nodes; your application talks to their endpoints. Both work. The difference is in what each one treats as the core product.

Infura thinks the core product is reliable, neutral access to the chain. Alchemy thinks the core product is a developer platform that happens to include chain access.

That distinction sounds minor. It isn't.

How Both Actually Work

When your application calls eth_getBalance or sends a signed transaction, it's making a JSON-RPC call. That call needs to hit a node connected to the network. Infura and Alchemy both expose HTTPS and WebSocket endpoints that accept these calls and route them to their underlying node infrastructure.

Infura launched in 2016 — before most of the current ecosystem existed — and was acquired by ConsenSys. For years, it was essentially the only option. MetaMask defaulted to Infura's endpoints for all user transactions, which created a significant concentration point: when Infura had outages (and it did), a large fraction of Ethereum users couldn't send transactions at all. The dependency was that deep.

Infura's approach is straightforward. You create a project, get an API key, and point your application at their endpoint. IPFS gateway access is included. Multi-chain support covers Ethereum mainnet, testnets, Polygon, Linea, and others. It's a relay layer. Reliable, widely trusted, and not trying to be more than it is.

Alchemy launched in 2019 with a different frame. Rather than pure RPC relay, it positioned itself as a developer platform — the "AWS of web3" framing they've used in fundraising materials. The infrastructure is there, but the real pitch is what's built on top of it.

The practical differences: Alchemy's Supernode architecture runs redundancy across multiple nodes rather than routing you to a single node, which they argue reduces the stale-read and failed-broadcast problems that appear under load. On top of that, they've built APIs that don't exist in the raw JSON-RPC spec: an NFT API for querying token holdings without manually parsing transfer events, a Transfers API for transaction history, webhook notifications via Alchemy Notify, and alchemy_simulateExecution for dry-running transactions before broadcasting them. There's also Alchemy Monitor — a debugging dashboard that logs request errors, tracks method usage, and surfaces latency issues.

None of these enhanced APIs are available through Infura's standard interface.

Where the Constraints Actually Live

Both providers introduce the same fundamental constraint: you're trusting a third party with your node access. This matters more than it might seem.

An RPC provider can theoretically:

• Return stale or incorrect state
• Selectively block requests (by address, geography, or IP)
• Go down and take your application with it

The second point became concrete in August 2022 when the U.S. Treasury's OFAC sanctioned Tornado Cash, and both Infura and Alchemy blocked RPC requests associated with sanctioned addresses. This wasn't a hack or a policy failure — it was both companies responding to legal pressure by filtering traffic at the infrastructure layer. For applications expecting "neutral" relay, it was a reminder that neutrality is conditional on regulatory environment.

MetaMask's longstanding default to Infura has also created what's effectively a single-provider bottleneck for millions of wallets. Multiple Ethereum outage incidents have traced back to Infura degradation. MetaMask has since moved toward multi-provider fallback architecture, but the concentration risk illustrated why node provider diversity matters.

What's Changing

The centralized RPC provider model is being challenged from below. Pocket Network (POKT) was early to the decentralized RPC idea — a protocol where node operators are paid in POKT tokens for serving RPC requests, distributing the relay function across hundreds of independent operators. Lava Network and dRPC are newer entrants with similar architectures.

The honest assessment: decentralized RPC is still early. Reliability and latency haven't yet matched Infura or Alchemy for production use cases. But the gap is closing, and the Tornado Cash episode gave developers a clear reason to care about it.

On the Alchemy side, their trajectory is moving further into the developer platform direction — into account abstraction (ERC-4337) bundler infrastructure, gas manager services, and embedded wallet SDKs. They raised at a $10.2B valuation in 2022 and have been extending into adjacent infrastructure categories.

Infura, through ConsenSys, is navigating the broader restructuring that ConsenSys has undergone. The core infrastructure remains stable and widely used; the strategic direction is less clear than Alchemy's.

What Would Confirm or Break This

For Alchemy's platform thesis:

• Confirmation: Enhanced APIs (NFT API, Transfers API, simulation) become the reason developers choose Alchemy over alternatives — not just the RPC relay
• Confirmation: AA bundler and gas manager services see production adoption as ERC-4337 usage grows
• Invalidation: A reliability incident or API failure that causes major production breakage; developer trust shifts

For decentralized RPC alternatives:

• Confirmation: A production dApp of meaningful scale migrates from Infura/Alchemy to POKT or Lava as primary provider, citing censorship resistance
• Confirmation: Latency and reliability metrics for decentralized providers reach parity in independent benchmarks
• Invalidation: Another OFAC-style event occurs and both centralized providers comply without meaningful developer migration — suggesting the market accepts the tradeoff

Timing Perspective

Now: For most developers, Infura or Alchemy is the right default. Alchemy's enhanced APIs are genuinely useful for applications that need NFT data, transaction history, or simulation without building indexing infrastructure themselves.

Next: The ERC-4337 account abstraction rollout creates new infrastructure requirements (bundlers, paymasters) that Alchemy is positioning to own. If AA adoption accelerates over the next 12-24 months, the provider landscape could shift meaningfully.

Later: If decentralized RPC networks reach reliability parity, the architecture looks different — censorship-resistant relay as a default, with enhanced API layers potentially sitting on top. That's a multi-year horizon.

What This Doesn't Cover

The choice between Infura and Alchemy is an infrastructure decision, not a security decision. Neither protects you from smart contract bugs, key management mistakes, or protocol-level exploits. And neither choice eliminates third-party dependency — it just determines whose infrastructure you depend on.

For developers who need genuine node-level independence, the answer is running your own node (or at least a fallback), which is increasingly accessible through light client options and hardware like Dappnode. That's a separate topic.

The static explanation is here. Whether the provider choice matters for your specific application depends on what you're building — and how much you care about the censorship-resistance properties of the relay layer you're using.
