trusted AI agents
The T3N sandbox gives developers everything to build agents with verifiable identity, programmable authorization, and secure payments. Claim 20,000 test tokens and start shipping.
- 20,000 test tokens — enough for 25 agents and ~5,000 protected actions.
- Full SDK access — npm, MCP server, plus a Stripe-backed test merchant.
- One signup, every protocol — A2A, ERC-8004, Entra Agent ID, MCP, Web Bot Auth.
Ship trusted actions.
The T3N sandbox is the full stack — same SDK, same enclaves, same protocol coverage as production. We're just covering your gas.
20,000 T3N
Test tokens, instantly
Enough to register up to 25 agents and run roughly 5,000 protected actions.
25 did:t3n
Verifiable agent identities
Cryptographically signed, W3C-compliant decentralized identifiers. Resolve to A2A cards, ERC-8004, Entra Agent ID — register once.
Stripe test mode
Agent Connect payments
Real placeholder-resolution flow inside the TEE. Run end-to-end payment intents with test cards — no PCI scope on your side.
Full SDK + MCP
Every integration surface
npm package, MCP server, CLI, REST/SDK, sample apps. Drop into LangChain, CrewAI, AutoGen, or roll your own.
No credit card, ever • Preferential Mainnet pricing locked for T3N sandbox builders
From signup to first protected action in 5 minutes
Sign in with Google and enter an optional campaign code. We’ll instantly provision your T3 decentralized ID (DID) and queue up your test tokens.
Copy your API key directly from the success screen. Your test tokens and DID will be assigned automatically to that API key. Note: During the test phase, you will not be able to retrieve your API key after this page, so please make sure to store them somewhere safe before you move on.
npm install, initialize the client, and provide your API key. Set to testnet — your app can open an authenticated TEE session and deploy your contract in 5 minutes.
import { T3nClient, loadWasmComponent, setEnvironment, createEthAuthInput, eth_get_address, metamask_sign, } from "@terminal3/t3n-sdk"; setEnvironment("testnet"); // your API key const key = process.env.T3N_API_KEY!; const address = eth_get_address(key); const client = new T3nClient({ // all crypto runs inside WASM wasmComponent: await loadWasmComponent(), // signs your login challenge handlers: { EthSign: metamask_sign(address, undefined, key) }, }); // open an encrypted session in the TEE await client.handshake(); // prove your wallet → your did:t3n:… await client.authenticate(createEthAuthInput(address)); // your token balance const { balance } = await client.getUsage(); console.log(`Credits available: ${balance.available}`); ▍
These are the reference agents shipping with the T3N sandbox. Click any orbit node to explore the contract and the sample call. Clone any one, swap in your data, and you're 30 minutes from a working demo.
An agent that reads HR data and triggers bank transfers — without ever holding raw account numbers. The flagship demo for Super AI Week.

No — the campaign code is entirely optional. It exists for hackathon partners, conferences, and ecosystem programs that might be granting bonus tokens. Sign up without one and you still receive the full 20,000 T3N starter allocation.
