This page picks up where [Quickstart](https://docs.terminal3.io/developers/adk/get-started/quickstart) leaves off. Complete that first — you should already have an authenticated `T3nClient` and your `tenantDid` before starting here.

1. **Get your API key and DID**  
If you haven’t already, get your DID, download your API key, and claim test credits from the [claim page](https://docs.terminal3.io/developers/adk/get-started/prerequisites/request-test-tokens) — it’s self-serve, no approval needed.

2. **Install Rust + WASM toolchain**  
[TEE contracts](https://docs.terminal3.io/t3n/how-t3n-works/tees#tee-contract) are compiled to WebAssembly (WASM) binaries, built with the Rust toolchain. If you don’t already have `rustup`/`cargo` installed:

```bash
   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh   # choose the default option when prompted
   source "$HOME/.cargo/env"
   ```
   Then add the WASM target:
   ```bash
   rustup target add wasm32-wasip2          # WASI Preview 2 build target — a few seconds
   cargo install wasm-tools                 # optional — inspect/verify the component
   ```
   `cargo install wasm-tools` compiles roughly 100 crates from source and takes about 2 minutes with no progress output in between — that’s normal, not a hang.

3. **Build a TenantClient from your session**  
Contracts are registered and managed through a `TenantClient`, built around the `tenantDid` you already obtained in Quickstart — never construct or derive this value yourself. Append this to the bottom of the same `quickstart.ts` you created in Quickstart — it needs `t3n` and `tenantDid` from that file’s scope:
   ```typescript
   import { TenantClient, getNodeUrl } from "@terminal3/t3n-sdk";

const tenant = new TenantClient({
     t3n,                    // the T3nClient you already authenticated in Quickstart
     baseUrl: getNodeUrl(),  // the active node from setEnvironment()
     tenantDid,               // did.value from Quickstart — never hardcode
   });

await tenant.me(); // throws if something's wrong; confirms the client actually works
   console.log("TenantClient ready.");
   ```
   Run it the same way as before — `npx tsx quickstart.ts` — and confirm you see `TenantClient ready.` printed after your `tenantDid` line.

**This authenticates you to manage your own deployment** — a different job from agent authentication. The DID must equal the one admitted as a tenant in `idx:_tenants`: exactly the `tenantDid` you already have from Quickstart.
