base on The breakthrough smart contract platform ushering in the next era of money. Nibiru powers an ecosystem of dApps including perps, RWAs, and more. # Nibiru [![Go Reference](https://pkg.go.dev/badge/github.com/NibiruChain/nibiru.svg)](https://pkg.go.dev/github.com/NibiruChain/nibiru/v2#section-readme) [![Nibiru Test workflow][badge-go-linter]][workflow-go-linter] [![Nibiru Test workflow][badge-go-releaser]][workflow-go-releaser] [![GitHub][license-badge]](https://github.com/NibiruChain/nibiru/blob/main/LICENSE.md) **Nibiru** is a breakthrough Layer 1 blockchain and smart contract ecosystem providing superior throughput, improved security, and a high-performance EVM execution layer. Nibiru aims to be the most developer-friendly and user-friendly smart contract ecosystem, leading the charge toward mainstream Web3 adoption by innovating at each layer of the stack: dApp development, scalable blockchain data indexing, consensus optimizations, a comprehensive developer toolkit, and composability across multiple VMs. **Table of Contents**: - [Documentation](#documentation) - [Community](#community) - [Nibiru Core Architecture](#nibiru-core-architecture) - [Execution Extensions](#execution-extensions) - [Auxiliary Modules](#auxiliary-modules) - [Consensus Engine](#consensus-engine) - [Developing in this Codebase](#developing-in-this-codebase) - [Docker Development Environment](#docker-development-environment) - [How to Install Nibiru](#how-to-install-nibiru) - [License](#license) --- ## Documentation - [Nibiru Docs (nibiru.fi/docs)](https://nibiru.fi/docs/): This is the best resource for comprehensive technical, conceptual, and product documentation on Nibiru. - [Complete Golang reference docs](https://pkg.go.dev/github.com/NibiruChain/nibiru/v2#section-readme): (`pkg.go.dev`) For the blockchain implementation. - [Nibiru RPC Endpoints](https://nibiru.fi/docs/dev/networks/) - [Core Tools and Language Clients](https://nibiru.fi/docs/dev/#core-tools-and-language-clients) ## Community If you have questions or concerns, feel free to connect with a developer or community member in the [Nibiru Discord][social-discord].

Nibiru EVM is an extension of "[geth](https://github.com/ethereum/go-ethereum)" along with "web3" and "eth" JSON-RPC methods. | | [Wasm][code-x-wasm] | Implements the execution environment for WebAssembly (WASM) smart contracts. CosmWasm smart contracts are Rust-based, Wasm smart contracts built for enhanced security, performance, and interoperability. See our [CosmWasm sandbox monorepo (nibiru-wasm)](https://github.com/NibiruChain/nibiru-wasm/tree/main) for the protocol's core smart contracts. | | [Eth][code-x-eth] | Ethereum integration utilities: EVM JSON-RPC server (HTTP/WebSocket) and APIs (eth/net/web3/debug/txpool), EVM transaction indexer for fast lookups, EIP-155 chain IDs, and EIP-712 signing helpers. See also [server][code-app-server] for JSON-RPC bootstrap and config. | | [App][code-app] | Core application logic including custom ante handlers for transaction preprocessing, gas management, signature verification, and EVM integration. Key features include oracle gas optimization, zero-gas actors, and enhanced security guards. | | [x/nutil][code-x-nutil] | Helper and utility functions to be utilized by other `x/` modules. | ### Auxiliary Modules | Module | Description | | --- | --- | | [Devgas][code-x-devgas] | The `devgas` module of Nibiru shares contract execution fees with smart contract developers. This aims to increase the adoption of Nibiru by offering CosmWasm smart contract developers a direct source of income based on usage. | | [Epochs][code-x-epochs] | The `epochs` module allows other modules to set hooks to be called to execute code automatically on a period basis. For example, "once a week, starting at UTC-time = x". `epochs` creates a generalized epoch interface. | | [Inflation][code-x-inflation] | Implements the [tokenomics](https://nibiru.fi/docs/learn/tokenomics.html) for Nibiru. | | [Oracle][code-x-oracle] | Nibiru accurately prices assets using a native, system of decentralized oracles, and communicates with other Cosmos layer-1 chains using the Inter-Blockchain Communication (IBC) protocol. Nibi-Oracle handles the voting process for validators that act as oracles by updating data feeds. | | [Sudo][code-x-sudo] | Provides an on-chain "root" and a set of whitelisted contracts with elevated permissions. Includes management of Zero Gas Actors for fee-less CosmWasm executions against approved contracts. | [code-x-nutil]: https://github.com/NibiruChain/nibiru/tree/main/x/nutil [code-x-devgas]: https://nibiru.fi/docs/dev/x/nibiru-chain/devgas.html [code-x-epochs]: https://github.com/NibiruChain/nibiru/tree/main/x/epochs [code-x-inflation]: https://github.com/NibiruChain/nibiru/tree/main/x/inflation [code-x-oracle]: https://github.com/NibiruChain/nibiru/tree/main/x/oracle [code-x-wasm]: https://nibiru.fi/docs/wasm/ [code-x-evm]: https://github.com/NibiruChain/nibiru/tree/main/x/evm [code-x-eth]: https://github.com/NibiruChain/nibiru/tree/main/eth [code-app-server]: https://github.com/NibiruChain/nibiru/tree/main/app/server [code-app]: https://github.com/NibiruChain/nibiru/tree/main/app [code-x-sudo]: https://github.com/NibiruChain/nibiru/tree/main/x/sudo ### Consensus Engine Nibiru is built on [Tendermint Core (CometBFT)](https://tendermint.com/core/) consensus. --- ## Developing in this Codebase Install `just` to run project-specific commands. ```bash cargo install just ``` Nibiru projects use `just` as the command runner instead of `make`. The `just` tool is a modern command runner that's simpler, more readable, and self-documenting. ```bash just # list all available commands just build # build the nibid binary just localnet # run a local network just test-e2e # run EVM end-to-end tests ``` Ref: [github.com/casey/just](https://github.com/casey/just) ### Docker Development Environment For a complete local development environment with multiple services, use our Docker Compose setup that includes: - **Multiple validator nodes**: Two independent Nibiru Chain nodes for testing multi-node scenarios - **Pricefeeder services**: Automated price oracle data feeds - **IBC relayer**: Cross-chain communication testing with Hermes relayer - **Heart Monitor**: Blockchain indexing and GraphQL API for monitoring See [contrib/docker-compose/README.md](./contrib/docker-compose/README.md) for detailed setup instructions and usage examples. ## How to Install Nibiru Assuming you already have Go installed and common tools like `gcc` and `jq`, the only commands you need to run are: ```bash just install # to build the node software to make a Nibiru binary just localnet # to run a local instance of Nibiru as a live network ``` For installation instructions from scratch, please see [INSTALL.md](./INSTALL.md). Usage instructions for the `nibid` CLI are available at [nibiru.fi/docs/dev/cli](https://nibiru.fi/docs/dev/cli) and the [Nibiru Module Reference](https://nibiru.fi/docs/concepts/arch/#modules-%E2%80%94-nibiru). <details> <summary>[Recommended minimum specs to run a full node]</summary> - 2CPU, 4GB RAM, 100GB SSD - Unix system: MacOS or Ubuntu 18+ </details> ## License Unless a file notes otherwise, it will fall under the [BSD-2-Clause License](./LICENSE.md).
