The best Monad RPC providers are the ones built for a chain that produces a block every 300 milliseconds: stable WebSocket connections, workable eth_getLogs limits, and archive access that doesn’t inflate your bill. QuickNode, Alchemy, Chainstack, dRPC, Ankr, and NOWNodes all serve Monad mainnet, but they differ in pricing model, rate limits, and how much debugging data they expose.
Monad is an EVM-compatible layer-1 blockchain that launched its public mainnet on November 24, 2025. According to the official Monad documentation, it targets 10,000 transactions per second, 300 ms block frequency, and 600 ms finality. That pace changes what an RPC endpoint has to survive, and it’s the reason free public endpoints run out of room quickly.
This guide moves from basics to detail: what a Monad RPC provider is, why you need one, who uses it, how to compare the options, and where six providers differ.
What Is a Monad RPC Provider?
A Monad RPC provider is a company that runs Monad nodes and gives your application an HTTPS or WebSocket endpoint to reach them. Through that endpoint the app reads balances, fetches blocks, simulates calls, and broadcasts signed transactions.
RPC stands for Remote Procedure Call: your code asks a remote server to run a function and return the result. Monad supports the standard Ethereum JSON-RPC API, so methods like eth_getBalance, eth_call, and eth_sendRawTransaction look the same as on Ethereum. Libraries such as ethers.js and viem generally work after you swap the endpoint URL and set the mainnet chain ID to 143.
The node is the software that holds the chain’s state and validates new blocks. A provider keeps that software synced, monitors it, and puts load balancing in front of it. If the difference between node roles is new to you, our guide to types of blockchain nodes covers it.
Why Do You Need a Dedicated Monad RPC Provider?
You need one because Monad’s public endpoints are capped for light use, and the chain’s speed makes those caps bite sooner than on slower networks. Here’s how the limits look in the Monad network documentation and RPC limits reference:
| Public endpoint (operator) | Rate limit | eth_getLogs block range |
|---|---|---|
| rpc.monad.xyz (QuickNode) | 25 requests/sec | 100 blocks |
| rpc1.monad.xyz (Alchemy) | 15 requests/sec | 1,000 blocks |
| rpc3.monad.xyz (Ankr) | 300 requests/10 sec | 1,000 blocks |
| rpc-mainnet.monadinfra.com (Monad Foundation) | 20 requests/sec | 100 blocks |
The log ranges look small because the blocks are dense. Monad’s docs explain that a block arrives every 300 ms and can hold up to 3,750 transactions and 150M gas of computation. A 100-block window covers only 30 seconds of chain history.
That’s a problem for anything that backfills events, such as an indexer or a portfolio tracker. It also breaks polling. With three blocks per second, an app checking eth_blockNumber once a second will skip blocks, so real-time features need WebSocket subscriptions instead. Our guide to WebSocket best practices for production covers reconnect and heartbeat handling.
Speed also brings quirks. Because Monad executes transactions asynchronously, eth_sendRawTransaction can initially accept a transaction that later fails on a nonce gap or insufficient balance. The network also has no visible mempool for pending transactions, so eth_getTransactionByHash returns null until a transaction lands in a block. A good provider documents these behaviors and gives you tools to handle them.
Who Uses Monad RPC Providers?
Almost every application that touches Monad does, since the chain is only reachable through a node. What differs is which part of the RPC surface each one leans on.
- DeFi protocols and front ends call
eth_callconstantly to quote swaps, check collateral ratios, and simulate transactions before a user signs. - Trading and arbitrage bots care about latency and WebSocket stability. On a 300 ms block cadence, a slow or dropped connection means acting on stale state.
- Wallets read balances, estimate gas, and broadcast signed transactions, so they need consistent uptime more than exotic methods.
- Indexers and analytics tools backfill events with
eth_getLogsand often need archive access for historical state. - Developers debugging contracts rely on
debug_trace*methods to see internal calls. Monad’s docs note that tracing defaults tocallTracerand that opcode-level struct logs are unsupported.
Monad’s design explains why this traffic is heavier than on older EVM chains. Co-founder Keone Hon described the approach in an interview with CoinMarketCap: “We’re transitioning the EVM from single-threaded to multithreaded computation. This allows multiple transactions to be processed simultaneously, significantly increasing throughput.”
More throughput means more transactions and more events per second for every app to read. The RPC layer is where that load lands.
How to Choose a Monad RPC Provider
Start with your workload, not the price list. A wallet, an indexer, and a trading bot stress completely different parts of the same API. Work through these checks in order:
- Confirm mainnet support and WebSocket stability. The Monad providers page lists 18 services, but a listing doesn’t tell you how a WebSocket behaves at 300 ms blocks. Open a subscription and leave it running.
- Check
eth_getLogslimits. Public endpoints allow 100 to 1,000 blocks per call. Ask what a paid plan allows before you build an indexer on it. - Verify archive and trace access. Historical state and
debug_trace*calls are where providers diverge most, and where billing multipliers hide. - Read the billing model. Some providers charge one unit per request. Others weight each method, so a trace call can cost several times a balance check.
- Test latency from your own region. Independent tools like CompareNodes run p95 latency checks from 30 locations on six continents against dozens of Monad endpoints.
- Plan for failover. One endpoint is one point of failure, so keep a second provider configured.
Top Monad RPC Providers Compared
The six providers below all list Monad mainnet support. Pricing and limits change often, and several figures come from the vendors’ own pages or from Chainstack’s Monad provider comparison, which is itself a competitor’s view. Treat the numbers as a starting point and confirm them on each pricing page.
| Provider | Billing model | Dedicated nodes | Archive / trace | Notable detail |
|---|---|---|---|---|
| NOWNodes | Request-based plans | Yes | Archive and Debug & Trace listed | 120+ networks on one account |
| QuickNode | Credits with method multipliers (2-4x for trace, per Chainstack) | On higher tiers | Supported with multipliers | Operates the rpc.monad.xyz public endpoint |
| Alchemy | Method-weighted compute units | No standard offering (per Chainstack) | Partial on mainnet (per Chainstack) | Operates rpc1.monad.xyz |
| Chainstack | Request units: 1 standard, 2 archive/debug | From $0.50/hr | Yes, on Global Nodes | Free tier of 3M units/month |
| dRPC | Flat, about $6 per 1M requests | Yes | Supported | Paid plans from $10/month |
| Ankr | Credits, pay per call | Premium plans | Premium only | Operates rpc3.monad.xyz |
NOWNodes
NOWNodes provides Monad RPC and WebSocket access, archive nodes, and a Debug & Trace API through the same account that covers 120+ other networks. Its Monad page lists shared and dedicated options, a 99.95% uptime figure, and no predefined RPS limit on paid plans. The free Start plan includes 100,000 requests.
A dedicated node is isolated to one customer and limited by hardware, not by a request quota, which suits sustained high-volume workloads. The trade-off is scope: a team building Monad-only tooling may want a specialist. The page also doesn’t state testnet availability for Monad, so confirm that before building a test pipeline. Current plan details are on the pricing page.
QuickNode
QuickNode runs one of the Monad Foundation’s listed public endpoints, so its infrastructure is already handling live Monad traffic. Its credit system applies multipliers to heavier methods, which makes trace-heavy workloads harder to forecast. Compliance certifications such as SOC 2 Type II matter for enterprise buyers.
Alchemy
Alchemy suits teams already using it for other EVM chains, since Monad access sits in the same dashboard. Its compute-unit model weights methods differently, and Chainstack’s comparison notes that a debug_traceTransaction call costs 300+ units. Confirm archive and trace behavior on mainnet before relying on them.
Chainstack
Chainstack bills one request unit for standard calls and two for archive or debug calls, which keeps trace-heavy costs closer to predictable. It offers dedicated nodes from $0.50 per hour and lists a 99.99%+ SLA on Global and Dedicated nodes. Its pricing figures here come from Chainstack’s own comparison, so weigh that source accordingly.
dRPC
dRPC charges a flat rate per request regardless of method, and the Monad docs list paid plans starting at $10 with no rate limits. Free access exists through rate-limited public endpoints. Chainstack’s comparison notes that the free tier carries no formal SLA.
Ankr
Ankr operates rpc3.monad.xyz, which allows 1,000-block eth_getLogs ranges and a 1B gas allowance for eth_call, both above the other public endpoints. Its credit-based free tier is large, but archive and trace access sit on premium plans. Per Chainstack, Ankr publishes no SLA outside enterprise contracts.
Shared vs Dedicated Monad Nodes: Which One Fits?
Shared nodes fit development and moderate production traffic, while dedicated nodes fit sustained high-volume, latency-sensitive, or privacy-sensitive workloads. The table shows how NOWNodes describes the split on its shared nodes and dedicated nodes pages. Other providers draw the line in similar places.
| Factor | Shared node | Dedicated node |
|---|---|---|
| Infrastructure | Pooled across customers | Isolated for one customer |
| Limits | Plan quotas and rate limits | No predefined RPS limit; hardware-bound |
| Configuration | Standard interfaces | Configurable clients and method access |
| Typical fit | Testing, wallets, moderate dApps | Indexers, trading systems, heavy tracing |
“No predefined limit” doesn’t mean infinite capacity. Hardware still sets the ceiling, and on a chain that can fit 3,750 transactions in a 300 ms block, that ceiling matters. For prototypes, free public endpoints with low rate limits are usually enough.
Edge Cases Worth Testing Before Launch
A few Monad-specific behaviors cause bugs that don’t show up on other EVM chains:
- Chunk your log queries. Split
eth_getLogsbackfills into ranges that match the provider’s limit, and retry on range errors. - Don’t trust the first response. Deferred validation means a broadcast can be accepted and still fail. Confirm inclusion by receipt, not by the send call.
- Skip unsupported subscriptions. The
newPendingTransactionsandsyncingWebSocket subscriptions aren’t supported, so mempool-watching bots need another design. - Mind gas allowances on
eth_call. Requests are routed to a low-gas pool up to 8.1M gas and a high-gas pool above that, and the high-gas pool has limited concurrency. - Run two providers. Route reads through a failover so one provider’s bad hour doesn’t become yours.
Conclusion
No single Monad RPC provider wins for every workload. Pick by what your application stresses: WebSocket stability for bots, log limits and archive access for indexers, predictable billing for trace-heavy debugging, or uptime and support for a wallet.
Before you commit, run three tests: hold a WebSocket open for a day, backfill a week of logs, and send transactions from your target region. Then keep a second endpoint ready. If Monad is one of several chains in your product, a multi-chain provider such as NOWNodes lets you manage keys and billing in one place, while Monad-only teams may weigh specialists more heavily.
FAQ
What is the Monad mainnet chain ID?
The Monad mainnet chain ID is 143, and the native currency symbol is MON. Add both to your wallet or framework config along with your provider’s endpoint URL, as listed in the network information page.
Does Monad work with Ethereum tools like Foundry and MetaMask?
Mostly yes. Monad keeps full EVM bytecode compatibility and the Ethereum RPC API, so existing contracts and tooling work with little change. The differences are in edge behavior, such as unsupported blob transactions and deferred transaction validation.
Do I need an archive node for Monad?
Only if you query historical state or logs beyond what a standard node keeps. A wallet or a simple dApp usually doesn’t. Indexers, analytics tools, and compliance reports usually do, so check whether the provider bills archive calls at a higher rate.
Can I run my own Monad node instead of using a provider?
Yes. The Monad docs say the network is designed with minimal hardware requirements to encourage broad node participation. You still handle syncing, upgrades, monitoring, and failover, which is why most application teams pay a provider for endpoints and keep self-hosting for special cases.
