🔹Orbion SDK & API

Orbion SDK & API provide developers with the tools and interfaces to build, monitor, and interact with the Orbion blockchain at scale.

From dApp deployment to data analytics, Orbion exposes a set of standardized RPC interfaces, SDK packages, and indexable APIs that ensure developers can build quickly — without vendor lock-in or opaque infrastructure.

🔧 SDK Overview

Orbion offers native support for:

✅ Web3.js & Ethers.js

Orbion is fully EVM-compatible and works out-of-the-box with:

npm install web3
npm install ethers

Example:

const { ethers } = require("ethers");

const provider = new ethers.JsonRpcProvider("https://rpctestnet-1.orbionchain.com");

const block = await provider.getBlockNumber();
console.log("Current block:", block);

Compatible with all Ethereum toolchains: Hardhat, Foundry, Remix, Truffle, etc.

📡 JSON-RPC Support

Orbion nodes expose the full Ethereum JSON-RPC 1.0 spec:

Method Type	Examples
Read	eth_getBalance, eth_call, eth_blockNumber
Write	eth_sendRawTransaction, eth_estimateGas
Network	net_version, eth_chainId, web3_clientVersion

Full list of RPC endpoints can be found in the RPC Access section.
