ActiveFree Protocol Review 2026: Public RPC Access
Free Protocol, branded as rpcfree, offers public JSON-RPC endpoints for Ethereum, Base, Polygon, and Arbitrum without signup or an API key. Its free tier has clear limits, so it is best suited to light use and development rather than workloads that need higher capacity or archive access.

Our verdict on Free Protocol
7.3/10Free Protocol is a straightforward option for developers and wallet users who need public RPC access to Ethereum, Base, Polygon, or Arbitrum without signing up. Its strongest points are the no-key entry tier, usable examples, and clearly stated limits. The main caveat is that free capacity is bounded by IP rate and CU caps, and the site does not publish audit information. It suits light workloads and experimentation better than applications that depend on higher throughput or archive data.

What is Free Protocol?
Free Protocol, also branded rpcfree, is a public blockchain RPC service operated by Etox infrastructure. It provides endpoints for Ethereum, Base, Polygon, and Arbitrum One, letting compatible wallets and applications request data or interact with contracts without first creating an account.
The no-signup tier has published rate and CU limits, and the site provides code examples and a browser-based method tester. Higher-capacity options are described through Etox. Free Protocol is infrastructure, not a wallet or an exchange, and using an RPC endpoint does not remove the usual need to verify network and transaction details in your own wallet or application.
How Free Protocol works
Free Protocol provides an HTTP JSON-RPC endpoint for each supported network. A wallet or application sends a JSON-RPC request to the selected endpoint, such as a request for the latest block or a contract call, and receives a response. The site also lets visitors open an endpoint in a browser for documentation and try common methods in its tester.
The no-signup tier applies usage limits per client IP: 10 requests per second, a burst of 20, 333,333 CU per day, and 10 million CU per month. Different RPC methods consume different CU amounts. When a limit is exceeded, the service says it returns HTTP 429; users who need more capacity can look at the separately described Etox tiers.

Four network endpoints
Public JSON-RPC endpoints are listed for Ethereum, Base, Polygon, and Arbitrum One.
02
Keyless free access
The no-signup tier does not require an API key or credit card.
03
Client examples
The site provides snippets for curl, ethers.js, viem, web3.py, and Go.
04
RPC method tester
A browser-based tester offers common methods such as eth_blockNumber, eth_getBalance, and eth_call.
05
Published usage limits
The site lists per-IP rate and CU limits and says requests receive HTTP 429 after the limit is exceeded.
Pros and cons
What we like
- Supports four widely used EVM networks from one service.
- The public tier needs no signup, API key, or credit card.
- Lists rate and CU caps, including costs for several common RPC methods.
- Provides examples for popular programming languages and client libraries.
Watch out for
- Free access is limited by IP, request rate, and daily and monthly CU caps.
- The service may return HTTP 429 errors after the IP limit is reached.
- Archive data and trace/debug APIs are not listed in the no-signup tier.
- An RPC provider is an additional infrastructure dependency for wallets and applications; endpoint availability and response quality can affect access.
Free Protocol fees
The public tier is free and requires no signup, API key, or credit card. Its stated limits are 10 requests per second (20 burst), 333,333 CU per day, and 10 million CU per month per client IP. CU costs vary by method: the site lists 10 for eth_blockNumber, 26 for eth_call, 75 for eth_getLogs, and 309 for debug_trace.
The site lists an Etox Pro plan from $49 per month, with 300 million CU per month and 100 requests per second. Check the relevant plan details on the service before use, as fees and limits can change.
Is Free Protocol safe?
Free Protocol is an RPC infrastructure provider, not a custodian or wallet. The site identifies Etox as the operator, but does not publish audit information or detailed security assurances for the service. RPC providers can affect the availability and information returned to applications, so users and developers should verify important transaction details through their wallet and use infrastructure appropriate to their needs.
5 steps
How to get started with Free Protocol
- 1
Choose Ethereum, Base, Polygon, or Arbitrum on the Free Protocol site.
- 2
Copy the endpoint shown for that network.
- 3
Add the endpoint to a compatible wallet or configure it in an application that supports JSON-RPC.
- 4
Send requests using a client library or a tool such as curl; the site includes examples and a browser-based tester.
- 5
Track usage against the published per-IP request and CU limits, and consider another tier if your application needs higher capacity or archive data.
Who Free Protocol is for
Free Protocol is for developers, hobbyists, and wallet users who need a simple RPC endpoint on one of its four supported networks. It is a better fit for testing and light usage than for production services that require guaranteed capacity, archive access, or detailed security assurances.
Free Protocol FAQs
