Developers

There are many tools, libraries, SDKs, frameworks and utilities developers can use to interact with the blockchain, build their applications, and display them to users.

For current source-backed tooling, see Libraries & SDKs, Fleet, Sigma Rust, ergots, and Ergo Agent SDK.

Stack

Server

Interact with the blockchain locally or via a remote server.

Browser

Interact with users in browser

Desktop

Create a local application.

Mobile Application

Creating a bundled mobile app for Android or iOS.

Choose a Stack

Build target	Best fit	Why	Main docs
Browser dApp	Fleet + dApp Connector	Common TypeScript path for browser wallets and transaction building.	Fleet, Browser, dApp Connector
JVM backend or exchange service	AppKit	Mature JVM tooling for node-backed services and transaction workflows.	AppKit, JVM, Exchange Integration
Rust service or constrained environment	sigma-rust	Core Rust libraries and bindings for wallets, WASM, and lower-level tooling.	Sigma Rust, Rust, Constrained Environments
Python automation or agents	Ergo Agent SDK / ergo-lib-python	Good fit for scripted workflows, agents, and data-heavy automation.	Ergo Agent SDK, Ergo-Lib-Python, Python
C# application	FleetSharp	.NET-oriented transaction tooling.	FleetSharp, C#
Mobile app	Native stack + sigma-rust bindings where needed	Mobile builds need wallet UX, signing constraints, and platform-specific packaging.	Mobile, Android, iOS
Contract prototype	ErgoScript tools + playgrounds	Best path for learning contract behavior before building full off-chain flows.	ErgoScript Tooling, Kiosk, Compiler

Use Libraries & SDKs when you need a fuller inventory.
