RPC Access & APIs

The Modulax blockchain exposes a standard Ethereum JSON-RPC interface, making it fully compatible with existing EVM tooling. Developers can deploy contracts, send transactions, and query chain state without any modifications to their workflow.

"If you can build on Ethereum, you can build on Modulax. RPC compatibility ensures zero switching cost."

Supported Methods

Modulax supports the full suite of Ethereum JSON-RPC methods. Commonly used endpoints include:

Method	Description
⁠ eth_blockNumber ⁠	Latest block number
⁠ eth_getBlockByNumber ⁠	Retrieve block details
⁠ eth_getTransactionReceipt ⁠	Check transaction status
⁠ eth_call ⁠	Simulate contract calls (no state)
⁠ eth_sendRawTransaction ⁠	Broadcast signed transactions

Example Usage

Using cURL

curl -X POST https://rpc.modulax.org
-H "Content-Type: application/json"
--data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

---

Using web3.js

import Web3 from "web3";
const web3 = new Web3("https://rpc.modulax.org");
async function main() { const block = await web3.eth.getBlockNumber(); console.log("Current block:", block); }
main();

Using ethers.js

import { ethers } from "ethers";
const provider = new ethers.JsonRpcProvider("https://rpc.modulax.org");
async function main() { const block = await provider.getBlockNumber(); console.log("Current block:", block); }
main();

Notes for Developers

• Gas Fees: paid in MDX, the native token of Modulax

• Network Name: Modulax

• RPC URL: https://rpc.modulax.org

• Chain ID: 648529

• Currency Symbol: MDX

• Block Explorer: https://explorer.modulax.org

Rate Limits: public RPC endpoints are subject to fair-use limits. For production dApps, consider running your own node.

Conclusion

The Modulax RPC interface mirrors Ethereum’s, ensuring compatibility with existing developer stacks such as Hardhat, Foundry, Truffle, ethers.js, and web3.js. This makes Modulax a drop-in extension of the EVM ecosystem.

"Modulax is not reinventing the wheel. It ensures your Ethereum tools work seamlessly while preparing for a quantum-secure future."
