# SDK

> Official Morpheum SDK (Rust + TypeScript), MWVM agent runtime, and related integration surfaces

## Overview

Morpheum exposes **SDK-style surfaces** at different layers: **chain and product APIs** ([morpheum-sdk](https://github.com/morpheum-labs/morpheum-sdk) for Rust, [morpheum-sdk-ts](https://github.com/morpheum-labs/morpheum-sdk-ts) for TypeScript), a **WASM agent runtime** (MWVM), and **protocol gateways** for tools and payments. Use this page to pick the right path and jump to the detailed guides.

## Morpheum SDK (Rust + TypeScript)

The product API is implemented as a **Rust** workspace and a **TypeScript** package in separate repositories. Capabilities align across stacks (signing, markets, VCs, transport), but install paths and docs live with each repo.

| Language       | Repository                                                              | Notes                                                                                                      |
| -------------- | ----------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------- |
| **Rust**       | **[morpheum-sdk](https://github.com/morpheum-labs/morpheum-sdk)**       | Native CLI, bots, and agents; **`morpheum-sdk-native`** and feature-gated crates (`market`, `vc`, `auth`). |
| **TypeScript** | **[morpheum-sdk-ts](https://github.com/morpheum-labs/morpheum-sdk-ts)** | Browser and Node; same conceptual API surface as the Rust SDK.                                             |

| Topic            | Notes                                                                                                                      |
| ---------------- | -------------------------------------------------------------------------------------------------------------------------- |
| **Facade**       | Unified `MorpheumSdk` entry point for operations across the stack.                                                         |
| **Signers**      | **NativeSigner**, **AgentSigner** (with TradingKeyClaim), MetaMask, Phantom, Taproot, and related flows.                   |
| **Capabilities** | Sign transactions, issue/revoke VCs, create markets, and more—via fluent builders and pluggable **gRPC + HTTP** transport. |
| **Modules**      | Rust: feature-gated crates so you compile only what you need.                                                              |

**Rust — upstream docs:** [README](https://github.com/morpheum-labs/morpheum-sdk/blob/main/README.md), [API Reference](https://github.com/morpheum-labs/morpheum-sdk/blob/main/API_REFERENCE.md), [Full guide](https://github.com/morpheum-labs/morpheum-sdk/blob/main/DOCUMENTATION.md), [Architecture](https://github.com/morpheum-labs/morpheum-sdk/blob/main/ARCHITECTURE.md).

**TypeScript — upstream docs:** [morpheum-sdk-ts](https://github.com/morpheum-labs/morpheum-sdk-ts) — start with the repo [README](https://github.com/morpheum-labs/morpheum-sdk-ts/blob/main/README.md).

Installation (**Cargo** for Rust, **npm** for TypeScript), versions, and feature flags are documented in each repo’s README.

## Agent runtime (MWVM)

**MWVM** is the primary SDK for building and running Morpheum agents with **chain-parity WASM**. It ships **Rust** and **TypeScript** entry points on top of the same guest ABI and host capabilities.

| Surface        | Role                                                                              |
| -------------- | --------------------------------------------------------------------------------- |
| **Rust**       | `mwvm::AgentRuntime::new()` — async host calls; backends, CLIs, embedded runners. |
| **TypeScript** | **mwvm-js** — WASM bindings for browsers and Node-style environments.             |

For wasmtime, inference, simulation, orchestration, and gateways (MCP, A2A, DID, x402), see **[MWVM](/mwvm)**.

## Wallets and signing

To fund execution paths and sign where your stack requires it, use **[Agent wallet](/agent-wallet)** and the **[Signing](/signing)** guides (Ethereum, Solana, Bitcoin, Morpheum, and related topics). For programmatic signing and claims in app code, use **[morpheum-sdk](https://github.com/morpheum-labs/morpheum-sdk)** (Rust) or **[morpheum-sdk-ts](https://github.com/morpheum-labs/morpheum-sdk-ts)** (TypeScript) where it matches your stack.

## APIs and automation

* **[MCP](/mcp)** — Model Context Protocol for tools, editors, and agent automation.
* **[x402](/x402)** — HTTP 402–style paid APIs and metered access; start from the x402 overview and **[cross-chain](/x402/cross-chain)** where relevant.

## Next steps

* New to the docs: **[Quickstart](/quickstart)** — pick MCP, CLI, or SDK and map your product type.
* Chain and product API: **[morpheum-sdk](https://github.com/morpheum-labs/morpheum-sdk)** (Rust), **[morpheum-sdk-ts](https://github.com/morpheum-labs/morpheum-sdk-ts)** (TypeScript).
* Run agents locally: **[MWVM](/mwvm)** — [github.com/morpheum-labs/mwvm](https://github.com/morpheum-labs/mwvm).
