# Developer Hub
Everything you need to build on Nibiru. Your go-to hub to develop smart contracts applications for the decentralized web.
# Nibiru Networks & RPC Endpoints
Easily configure your wallet, node, or dApp with Nibiru's network settings. Below are the RPC endpoints, network identifiers, and blockchain explorers for both the mainnet and testnet. For a full setup guide, including adding Nibiru as a custom network in your wallet, visit: Nibiru Networks and RPCs.

# Core Tools and Language Clients
Essential SDKs and tools for building applications on Nibiru.
| Tool / Library | Description |
|---|---|
| @nibiruchain/nibijs | A TypeScript SDK for building web applications in frameworks like Vue and React. It also supports interacting with wallet extensions like Keplr and MetaMask. Published as an npm package. |
| @nibiruchain/evm-core | Core Nibiru EVM (Ethereum Virtual Machine) TypeScript library with functions to call Nibiru-specific precompiled contracts. |
| @nibiruchain/solidity | Nibiru EVM solidity contracts and ABIs for Nibiru-specific precompiles and core protocol functionality. |
| Nibiru Rust SDK | Nibiru Rust standard library that includes the nibiru-std crate, offering protobuf types and traits for Wasm (WebAssembly) smart contracts on Nibiru. Available on crates.io. |
| Nibiru Command-Line Interface (CLI) | The nibid binary is needed for running nodes and sending IBC transfers without using a wallet extension. |
# Oracle Solutions

- Integrating with Oracles on Nibiru: Overview of available oracle solutions on Nibiru, including the native oracle and Band Protocol integration.
# Block Explorers
Nibiru Block Explorers: Block explorer for Nibiru
# Other Tools
Nibiru Golang SDK: Useful for developing agents and applications while directly importing types directly from the Nibiru source code.
Nibiru Python SDK: Similar to the TypeScript SDK, except written in Python.

# Undersanding the Nibiru Blockchain
See the Nibiru Architecure for comprehensive documentation.
Nibiru's Cosmos-SDK modules define the core logic for Nibi-Perps, Nibi-Swap, and the decentralized oracle network. Nibiru's modules are defined in the "x/" subfolder of the protocol's Golang code (e.g. the "evm" module is defined in the "x/evm" folder).
