Method reference
Zilliqa methods
Every method the Zilliqa gateway accepts, grouped by interface. 77 in total, read live from the node rather than kept by hand.
Mainnet is the live Zilliqa network. Every transaction it
accepts is final, and every ZIL balance it
reports is real money.
Testnet answers the same methods on a network funded with tokens that have no market value. Develop there, then change the URL to Mainnet when the code is stable. Nothing else about your integration has to change.
Everything below is served over JSON-RPC. Its endpoint differs per network, and all of them are in the gateway list above.
What sits between you and Zilliqa
A node is a machine running Zilliqa with a copy of the chain. Your code cannot ask the chain directly, it asks a node. The gateway picks a healthy one for every call, so you point at one URL instead of one machine.
Your application
FREE RPC gateway picks a healthy node
Node Node Node
- One URL, nothing to run or keep patched yourself.
- Calls routed to a node that is up and in sync.
- A failing node is skipped rather than returned to you as an error.
JSON-RPC
77 methods https://zilliqa-mainnet.gateway.tatum.io
The default. Every wallet, library and framework speaks it, and it is what you want unless you specifically need something else.
One POST carries a method name, its parameters and an id, and the response comes back on the same connection carrying that same id. Requests are independent, so there is no session to keep alive and nothing to reconnect, which is why it runs unchanged behind a load balancer or inside a serverless function. Send an array instead of a single object and the node works through the whole batch in one round trip.
Where it fits
- Anything your library already does for you. ethers, web3.js, viem and their equivalents all target this.
- Batching reads. One array of twenty calls costs one round trip instead of twenty.
- Stateless and serverless deployments, because nothing has to stay connected between calls.
- Historical queries, by passing a block number where you would otherwise pass latest.
Trade-offs
- It cannot push. Finding out that a block landed means polling for it, or moving to WebSocket.
- Wide log queries get refused. Page through in fixed block windows and merge the results yourself.
- Batch responses may come back in any order. Match them on id, never on position.

Common JSON-RPC errors
What you are most likely to hit calling this interface, and what to do about it.
- -32700
- Parse error. The request body was not valid JSON. Check that the body is serialised JSON and that Content-Type is application/json.
- -32600
- Invalid request. The JSON parsed, but it is not a well-formed JSON-RPC call. Include jsonrpc, method and id fields. A batch must be a non-empty array.
- -32601
- Method not found. This node does not expose the method you called. Check the spelling and the namespace, and confirm the method is in the list above for this network. Tracing methods in particular are not enabled everywhere.
- -32602
- Invalid params. The method exists but the arguments are wrong. Check argument order and types. Most EVM methods want hex-encoded quantities, and a block parameter such as latest or a hex height.
- -32603
- Internal error. The node failed while handling an otherwise valid request. Retry with backoff. If it persists on one method, it is usually that method rather than the node.
- -32000
- Server error. A catch-all the node uses for execution failures, most often a reverted call or a request over a limit. Read the accompanying message. Execution reverted means your call failed on chain, not in transport. Narrow the block range if you are querying logs.
- HTTP 429
- Rate limited. You have exceeded the free tier request allowance. Back off and retry, batch reads into single calls, or move to a dedicated endpoint for production traffic.
- HTTP 413
- Payload too large. The request body exceeded what the node accepts. Split large batches into smaller ones.

FAQ
Frequently Asked Questions
Everything you need to know about Zilliqa RPC endpoints
Quick Answer: What is Zilliqa RPC?
RPC (Remote Procedure Call) is the standard way to interact with the network programmatically - reading on-chain data, submitting transactions, and deploying smart contracts through JSON-RPC calls. The free tier ships 5 requests per minute with no registration required, which covers most learning and testing workflows. Production applications typically move to Tatum Premium for 200 requests per second and enterprise-grade reliability.
What is Zilliqa RPC?
RPC (Remote Procedure Call) is the interface that lets developers interact with the network: read on-chain data, submit transactions, and deploy smart contracts programmatically over standard JSON-RPC methods, without running your own node.
How do I connect to Zilliqa using these RPC endpoints?
Simply copy the RPC endpoint URL from above and configure it in your Web3 library (ethers.js, web3.js), wallet (MetaMask, Trust Wallet), or development tool (Hardhat, Truffle). The endpoint works immediately with no registration required for the free tier.
What are the rate limits for the free RPC tier?
Free tier RPC endpoints are limited to 5 requests per minute. This is perfect for testing and development. For production applications, we recommend upgrading to Tatum Premium which offers 200 requests per second with no daily limits.
Is Zilliqa RPC free forever?
Yes! Our free tier RPC endpoints are free forever with 5 requests per minute. This tier is perfect for learning, testing, and small projects. There are no hidden fees or time limits on the free tier.
What happens if I exceed the free tier rate limit?
If you exceed 5 requests per minute on the free tier, you'll receive an HTTP 429 (Too Many Requests) error. This is a standard rate limiting response. To avoid this, you can upgrade to Tatum Premium which offers 200 requests per second with no daily limits, perfect for production applications.
Can I use these Zilliqa RPC endpoints with MetaMask?
Yes! You can configure MetaMask to use our RPC endpoints. Simply copy the endpoint URL from above, go to MetaMask Settings > Networks > Add Network (or edit existing), and paste the RPC URL. This works with all EVM-compatible networks, including this one.
Are these RPC endpoints secure?
Yes, all our RPC endpoints use HTTPS encryption and follow enterprise-grade security practices. They're powered by Tatum's infrastructure which maintains 99.9% uptime.
What's the difference between mainnet and testnet RPC endpoints?
Mainnet carries real transactions with real value, so every write is final. Testnet runs on a separate network funded with free test tokens, which makes it the safe place to try new code, retry failed calls, and simulate edge cases. Always validate on testnet before pointing production traffic at mainnet.
How do I troubleshoot RPC connection errors?
If you're experiencing connection errors, check: 1) The RPC endpoint URL is correct, 2) You're not exceeding rate limits (5 req/min for free tier), 3) Your network allows HTTPS connections, 4) The network is currently operational. For persistent issues, check our status page or contact support.
Can I use these endpoints in production?
Free tier endpoints can be used in production for low-traffic applications (under 5 req/min). For production apps with higher traffic, we strongly recommend Tatum Premium for guaranteed uptime, faster rate limits, and enterprise SLA.
