What AGEN is
AGEN (Agentic Generative Evolving NFT) is a personal AI agent. It remembers what matters about you, talks by text or voice, and can be connected to other AI apps through MCP (Claude is the client we have tested). You decide what it keeps, and you can revoke the key of any app that uses it, or pause all access at once.
Each AGEN is an NFT on Ethereum, one per wallet. The NFT is the key to your agent: it proves who owns it, and sensitive actions ask for your wallet signature. It is not a financial product.
The name says what it is: Agentic, because it acts within the rules you set; Generative, because it writes and speaks its answers; Evolving, because its memory, skills and NFT metadata change as you use it; and an NFT, the key that proves it is yours. AGEN is the name of the product; your own agent goes by the name you give it.
Who it is for
- People who use AI every day and are tired of repeating the same context in every tool.
- Developers and builders who want an agent with memory and clear, revocable permissions.
- People who care about privacy and want to know what is stored, where it goes and how to delete it.
How it works for you
- You get an AGEN edition. The NFT is minted to your wallet.
- You open AGEN Live and talk to your agent by text or voice.
- The agent learns from your conversations and the documents you share. You see what it remembers, and you can pin or delete any item.
- You connect other AI apps through MCP. Each app gets its own key. You can see every access, revoke one app's key, or pause all access at any time.
- Every answer is measured in energy (Q). A visible receipt per answer is coming soon.

Energy plans and packs
Buying energy in advance, with the holder discount applied to the purchase price.
"Coming soon" means work in progress. Scope and dates can change.
Editions
All editions run the same agent. Higher editions add usage capacity and extras. Prices below are the current prices on this site.
| Edition | Price | What it gives you today |
|---|---|---|
| Access | US$ 25 | Your AGEN NFT in your wallet · Memory, chat and voice, MCP connections · Edition shown in the NFT metadata |
| Builder | US$ 75 | Everything in Access · Edition shown in the NFT metadata |
| Genesis | US$ 200 | Everything in Access · Edition shown in the NFT metadata |
| Founder | CHF 1,250 | Everything in Access · Edition shown in the NFT metadata · Direct contact with the team |
Usage limits today follow the number range of your NFT, not the edition. Limits by edition are coming soon.
Coming soon for holders: a discount on the purchase price of energy, never on the usage rate. Amounts will be published when energy plans open.
Energy and usage pricing
Your agent spends energy, measured in Q. One ruler everywhere: 1 Q = 1 QSIGNS = US$ 0.01. Q is a usage credit with a fixed price. It cannot be transferred, it does not change in value and it earns nothing.
| Level | Q per 1,000 tokens | Cost per 1M tokens | Typical use |
|---|---|---|---|
| Economy | 0.36 | US$ 3.60 | Short, simple tasks |
| Standard | 0.97 | US$ 9.70 | Everyday use (the default) |
| Premium | 3.5 | US$ 35.00 | Long or demanding answers |
- Tokens counted are input plus output.
- A typical message at the Standard level (about 1,300 tokens) costs about 1.3 Q, a little over one US cent.
- Every answer is measured in Q. A visible receipt per answer is coming soon.
- Chat, Live and MCP draw from the same balance. The rate is the same for every edition.
- Converting QST into energy is paused until legal review.
The QST token
QST is the QuantumStack ecosystem token, an ERC-20 on Ethereum. You do not need QST to use AGEN.
Token details will be published after legal review.
Evidence
We built a benchmark, AGEN Bench, to check whether memory and rules make a real difference. In our internal tests, with synthetic data:
95% vs 26%
useful answers with AGEN vs the same model without its context
0/80 vs 60/80
forbidden actions carried out with AGEN vs without the owner's rules
Synthetic owner profiles, not real users. A model given the right context by hand performs about as well; the gain is that you do not have to paste it every time.
Security and privacy
- Ownership of your agent is recorded on Ethereum. Sensitive actions ask for your wallet signature.
- Each app connected through MCP has its own key and its own access log. You can revoke one app's key or pause all access.
- Today, your agent's memory is kept per NFT on QuantumStack servers. You can see and delete it in the AGEN Hub. After a transfer, the new owner starts with a clean memory.
- Coming soon: stored memory encrypted with a key only you hold, so we cannot read it without you.
The limit, said plainly: during a conversation, the part of your context that is used goes to the AI provider that answers. Privacy here does not mean anonymity: card payments go through a payment provider and wallets are public.
Security work is reviewed internally on an ongoing basis. No external audit has been completed yet.
Where the money goes
Money from edition sales, and later from energy, pays for AI providers, servers, product development and security reviews.
The detailed allocation will be published once it is decided and reviewed by counsel.
Risks and limits
- Beta. AGEN is in beta. Features can change, break or be removed.
- Third-party AI providers. Answers come from external AI companies. Their availability, prices and data policies can change.
- Coming-soon features may change or be delayed. Do not buy an edition for a feature that is not available yet.
- No external audit yet. Smart contracts and servers can contain bugs.
- Wallets and networks. If you lose access to your wallet, you lose control of your AGEN. Network fees apply on Ethereum.
- Energy is measured in Q; charging is coming soon. The rates above are the ones the service uses to measure usage.
- Not an investment. Editions and Q are for using the product. Nothing here is financial advice.
